THE HORIZONTAL SEGMENT I. The Design Process A. The horizontal segment consists of two elements: 1. The horizontal cable and connecting hardware that provide the means for transporting the telecommunications signals between the network access module (NAM) in the work area and the horizontal cross-connect in the intermediate distribution frame (IDF). 2. The horizontal cabling pathways and spaces that distribute and support the horizontal cable and connecting hardware between the NAM and the IDF. Note: Cables that interconnect IDFs on the same floor, while physically horizontal in orientation, are considered part of the riser segment. B. This section describes the policies and procedures for the following design activities: 1. Determining the type and number of outlets in the work area. 2. Identifying the types and lengths of cable used in the horizontal segment. 3. Determining termination hardware requirements at the outlet. 4. Designing the structures needed to support the horizontal cabling. 5. Assigning the NAM numbers to the appropriate locations. 6. Cable testing procedures. II. The Type and Number of Outlets A. Work area outlets at UC Davis fall into three general configurations: basic, enhanced, and integrated. 1. The basic design supports voice or data applications. It consists of a single NAM supported by one 4-pair UTP Category 5e cable. A basic outlet may be used for a wall phone, a courtesy phone, a card reader, or to augment an existing work area with additional voice or data capacity. 2. The enhanced design supports voice and data applications. It consists of two NAMs per outlet. One 4-pair UTP Category 5e cable supports each NAM. The enhanced outlet is the most commonly used configuration at UC Davis. December 2000 Page 8 of 113

3. The integrated design supports complex systems including voice, data, and video applications. In general, it consists of three or more 4-pair UTP Category 5e cable supported NAMs per outlet. It may also consist of a combination of 4-pair UTP Category 5e cable supported NAMS with a 2- strand fiber optic cable supported NAM. B. The features of these three designs may be combined in the most cost-effective manner with Communications Resources approval. C. At least two enhanced outlets must be provided in each office and conference room. D. Laboratories require additional outlets to support workstations and test equipment. E. A 4 4 2½ inch back box with a single gang plaster ring must be used at each work area for NAM installations. From each backbox a minimum of ¾ conduit for basic and enhanced NAM, minimum 1 for integrated NAMs, will be run to the cable pathway support system. Conduit is to be sized appropriately for the fill of cable it is to accommodate. III. Cable Types and Lengths A. UC Davis recognizes two types of cables for use in the horizontal segment: UTP (unshielded twisted pair) cable and fiber optic cable. 1. UTP cable will be 4-pair, 24 AWG, solid conductor cabling that meets all the latest ANSI/TIA/EIA 568-A and TIA/EIA 568-A-1 Propagation and Delay Skew specifications for Category 5e cable, with all current Amendments and Bulletins, and must meet Anixter Level 6 (ALC-6) performance requirements. 2. Fiber optic cable will be a minimum of two strands, multi-mode, graded index, and tight-buffered cable. a) Fiber optic cable will be constructed with an aramid yarn strength member around the fiber sub units. b). Core Diameter 62.5 (+-) 3.0 um c) Cladding Diameter 125 (+-) 2.0 um d) Numerical Apeture 0.275 (+_) 0.015 e) Core to Cladding Offset 3.0um f) Core and Cladding Non-Circularity: (1) Core: <6.0 Percent (2) Cladding <2.0 percent g) Graded Index December 2000 Page 9 of 113

h) Coating to be mechanically strippable, dual layered, UV-cured acrylate applied by the fiber manufacturer. i) OVD Process 3. Performance: a) Bandwidth: (1) 850 nm >220 MHz at 1 km (2) 1300 nm > 600 MHz at 1 km b) Chromatic Dispersion: (1) Minimum Zero Dispersion Wavelength 1332 nm (2) Maximum Zero Disperson Wavelength: 1354 nm (3) Maximum Zero Dispersion Slope: 0.098 ps/nm.km c) Attenuation: (1) Max attenuation point discontinuity: <0.2 db at any design wavelength. (2) Bending Attenuation: induced @ 1550 nm, with 100 turns on 75mm diameter mandrel: <0.10dB. d) Attenuation Difference: at 1380 nm, <attenuation at 1300 nm + 1 db/km e) Water Immersion: (1) Induced attenuation, 23 degree C water immersion : <0.05 db/km 4. Manufacturer: a) Corning Cable Systems b) Avaya Communication c) Or equal. B. All conductive cabling and associated components must comply with Article 800 of the NEC (1996). Furthermore, all fiber optic cabling must comply with Article 770 of the NEC (1996). C. All cabling will be UL Listed Type CMP or OFNP if it is placed in air-handling plenums without conduit. The cable sheath will be marked with the UL listing. D. Horizontal cables will not be connected directly to telecommunications equipment. Suitable connecting hardware (i.e. patch panels/cords and punchdown blocks) and equipment cables must be used to make the connection. E. Horizontal UTP cable and fiber optic cable will not be spliced. F. The maximum lengths of horizontal distribution cables are shown in Table 2-1 (see Note). Horizontal Cables From the NAM to the horizontal cross-connect Used for patch cords and cross-connect jumpers in the horizontal cross-connect Maximum Length 295 feet 20 feet December 2000 Page 10 of 113

Table 2-1 Note: These limits apply to all types of horizontal cables. In establishing these limits, a 33-foot allowance was made for the combined length of patch cables and cables used to connect equipment in the work area and IDF. G. Equipment cables attach directly to active equipment and must meet the same performance requirements as the patch cords. Patch cables and cross-connect jumpers must not attach directly to active equipment. H. Cable slack must be provided at both ends of cable runs to accommodate future cabling system changes. 1. The minimum amount of slack must be 1 foot for UTP cables and 3 feet for fiber optic cables at the outlet. At the IDF, UTP horizontal cables are to meet manufactures procedures for slack, for patch panels, and 110 frames. 2. Service Loops placed during installation of 4-pair horizontal cable were tested and determined to cause Return Loss and NEXT problems on the order of 2-3dB. When creating service loops, they should be coiled in a Figure-eight configuration to eliminate this effect. 3. The fiber optic cable must have a 10-foot service loop at the IDF. 4. The slack must be included in all length calculations to ensure that the horizontal cable does not exceed 295 feet. IV. Termination Hardware Requirements at the Outlet A. Each UTP cable will be terminated at the outlet with an Ortronics GigaMo Solution: OR-60950011, OR-60950012 SERIES II, or OR-63750001 TRACJACK Module Information Outlet. (Face plates for the designated outlets must be from the same vendor.) B. Each fiber optic cable will be terminated at the outlet using a SC-style duplex connector mounted in a modular-coupling mounting module. Refer to Appendix A Specification 01 for details about NAMs. V. Assigning the NAM numbers to the appropriate locations, and NAM Matrices. The NAM matrices are used by Communications Resources department in the application of operational databases, for assignment of services to departments, and for other service related purposes. They are crucial to the implementation of service to the project. December 2000 Page 11 of 113

A. Each NAM will be pre-assigned a NAM number by the Communications Consultant on the project drawings prior to bid. B. NAM numbers shall be obtained by the Consultant from the UC Davis Line Assigner at 530-752-4598. Note: All additional NAM numbers shall be obtained only from the UC Davis Line Assigner at 530-752-4598. NAM numbers shall not be duplicated. C. After NAM numbers have been pre-assigned to the floor plans, the Consultant will complete the NAM matrices. Refer to Appendix A Specification 01 for information on NAM matrices. Nam matrices are to be completed at the beginning of Construction Document preparation. A hardcopy of NAM matrices shall be provided to UCD Project Manager, and excel 2000 spreadsheet file to be provided to Communications Resources. D. The Consultant will ensure that specifications are placed in the contract documents that inform the Cabling Contractor regarding use of and maintenance of the NAM matrices for the project. VI. Cross Connecting Voice NAMS. A. The Project Consultant shall ensure that the Contractor provides a Voice NAM Matrix, identifying all cross connections from the NAM to the BDF. B. The Voice NAM Matrix shall be provided to Communications Resources as part of the record drawing documentation. C. The Voice NAM Matrix shall be provided prior to final inspection of the cabling work VII. Structures to Support the Horizontal Cabling A. Special attention must be given when selecting and designing the type and layout of structures to support the horizontal cabling. The design must accommodate cabling changes with a minimum of disruptions to occupants. Note: UC Davis requires that the space above the ceiling grid be used, whenever possible, to route the horizontal cabling. B. Listed below are the steps needed to complete this phase of the design process: 1. Obtain an accurate set of floor plans. 2. Annotate, on the floor plan, the locations and types of outlets. December 2000 Page 12 of 113

3. Annotate, on the floor plan, the locations of the IDFs. If these locations have not been identified, please complete Section 3, The Intermediate Distribution Frame, before proceeding with this section. 4. Verify that the distance from each outlet to the horizontal cross-connect in the IDF does not exceed 295 feet. This distance must include the planned cable path as well as any vertical transitions. Note: If there are horizontal cable lengths that exceed 295 feet, the IDF must be relocated to a more centralized location or another IDF must be added. Section 3, The Intermediate Distribution Frame, addresses how to locate and size the IDF. 5. Sketch the route of the conduit and the cable tray on the floor plan. Note: The preferred method of routing the horizontal cabling is to run conduit from the outlet to a cable tray placed along natural building corridors. The cable tray then channels the cabling to the IDF. See Appendix A Specification 03 for conduit design considerations. a) A ¾-inch EMT conduit must be used from basic and enhanced outlet boxes to the cable tray. A 1-inch, or larger if appropriate, EMT conduit must also be used if the bulk of the cables to be supported exceed the recommended 40% fill ratio. b) A 1-inch, or larger, EMT conduit must be used from an integrated design outlet to the cable tray. See Appendix A Specification 04 for details on horizontal conduit capacity. c) All conduits will be firestopped in accordance with fire codes as interpreted by the State of California Fire Marshal. d) Conduit will be installed with a pull string with a minimum test rating of 200 pounds. e) The ends of conduits will be reamed and bushed to eliminate sharp edges that can damage cables during installation or service. Refer to Appendix A Specification 05 for cable tray specifications. 6. Identify firewalls or fire rated barriers that will be breached during cable installation. December 2000 Page 13 of 113

Note: All horizontal pathways that penetrate fire rated barriers must be firestopped in accordance with applicable fire codes. See Figure 2-1. Metallic dit Approved fire stop bl Fire rated b i Figure 2-1. Conduit must extend through the fire rated barrier when a fire rated barrier exists between the outlet and the cable tray. 7. Identify hard ceilings or ceilings with restricted access that must be traversed during cable installation. a) Multiple metallic conduits will be used in these areas. b) Conduits will be of a size that will ensure that a 40% fill ratio is not exceeded. Rigid conduit above hard ceilings Hard or limited access Cable December 2000 Page 14 of 113

Figure 2-2. Conduit placed above hard or limited access ceiling c) The ends of the conduit will be bonded and earthed. Conduit will be earthed to MTGB. Refer to Figure 2-2. d) Surface molding will be used to route cable from the work area outlet to the interstitial space in areas with limited ceiling access. 8. Identify outlets that will be located on walls that are not made of sheet rock construction such as plaster walls, concrete block walls, exterior walls, and insulated walls. Written approval must be obtained from the Manager, Systems Engineering & Development, Communications Resources to use surface mounted outlets if these walls cannot be fished. Note: Exterior walls, while furred and covered with sheet rock, may not provide the necessary clearance between the sheet rock and the backing material (commonly concrete block) for standard outlets. 9. Identify the location of system furniture that will be cabled for communications. System furniture can be fed from furred columns, wire whips from abutting walls, or power poles or under-floor systems. Note: The use of power poles will be minimized. 10. Minimum cable bend radii and conduit capacity must be considered when using a modular furniture system. Refer to Specification 03 for cable bend radii restrictions and Specification 04 for details on conduit capacity. 11. Annotate on the floor plan the cable paths that will be supported with J- hooks. Note: J-hooks will be placed at least every 4 feet to support the cable, and will be annotated on the construction drawings. December 2000 Page 15 of 113

VIII. Cable Testing Procedures A. General 1. Test and report on each intermediate cabling segment separately, including Main Distribution Frame (MDF) to Building Distribution Frame (BDF), riser cabling, station cabling, horizontal distribution (each segment, if multiple) and telecommunications closet wiring. 2. Test each end-to-end cable link. B. Voice Cabling Plant. 1. The Contractor shall perform tests on the Voice Telephone Plant cable. The tests shall be performed end-to-end from each termination block on each pair. Provide machine-generated documentation of all test results on Contractor-provided, and University s Representative-approved forms. This end-to-end test shall include the following: a) DC Continuity b) Reversals c) Shorts d) Opens e) Overall loop resistance/cable length f) Attenuation g) Splits C. UTP Horizontal Cable Testing 1. UC Davis requires that all UTP cable pairs be tested with a Level II or Level III tester for full compliance with Category 5e specifications regardless of intended use. 2. Test results must be provided for all conductor pairs of each cable. 3. The test results must be provided on a 3.5-inch MS-DOS formatted diskette in an MS Excel worksheet format. 4. EIA/TIA 568A Commercial Building Telecommunications Wiring specification must be used as a framework for testing UTP cable at UC Davis. 5. Field testing must comply with the EIA/TIA 568A specification. December 2000 Page 16 of 113

Table 2-2 describes worst-case channel performance at 100 MHz as presented in SP-4195 ( A-5). Parameter Specified Frequency Range Attenuation NEXT Power Sum NEXT ACR Power Sum ACR ELFEXT Power Sum ELFEXT Return Loss Propagation Delay Category 5e 1-100 MHz 24.0 db 30.1 db 27.1 db 6.1 db 3.1 db 17.4 db 14.4 db 10.0 db 548ns Delay Skew 50ns Table 2-2 Note: The Level II minimum limits for attenuation and NEXT accuracy are 1.0 db and 1.6 db respectively. 6. The overall (NEXT) or attenuation of a cabling run is a composite of the NEXT and attenuation of each of the components (UTP cable, NAM, patch panel, 110-block, patch cords, etc.) in that cable run. December 2000 Page 17 of 113

D. Fiber Testing 1. The horizontal fiber optic cable must be tested using a double-ended loss test. See Table 2-4 for proper fiber testing measures. a) The horizontal cable must be tested in-line between two reference cables. One cable will be attached to the source and the other to the meter to measure the db loss from both connectors, as well as any db loss associated with the cable between the connectors. Note: Because of the relatively short cable lengths within the horizontal segment (less than 295 feet), the main loss will be connector loss. b) The db loss for a horizontal segment must not exceed 2.0 db. c) TIA/EIA 526-14A outlines the steps required to test the horizontal fiber optic cabling. (1) Select two test jumpers. Ensure that the jumpers have a fiber core size of 62.5 µm and are connected with SC- style connectors (see Figure 2-3). (2) Ensure that the optical source meter is stabilized and has a center wavelength within ± 20 nm of the multi-mode nominal wavelength. (3) Ensure that the power meter and the light source are set to 850 nm if testing multi-mode fiber or 1310 if testing single mode fiber. (4) Ensure that all SC connectors are clean. Figure 2-3. SC- style connector. (5) Establish a reference. December 2000 Page 18 of 113

Note: A baseline must be established for the test jumper between the power meter and light source unit. (6) Verify the second test jumper by adding this second jumper between the power meter and the original jumper. Note: If the loss is greater than 0.5 db, clean all connectors (except the connector inserted at the source) and test again. If the loss is still unacceptable, replace the second test jumper. (7) Test the horizontal segment from each end of the fiber - from the NAM at the outlet and from the distribution cabinet in the communications room. Note: Because the length of the fiber optic cable in the horizontal segment is less than 295 feet, the main loss will be connector loss. (8) The total signal loss for a fiber link will not be greater than 2.0 db - this includes connector loss and fiber loss. (9) Once the test is successful, electronically capture the results or note the attenuation level. Note: reversing the direction of test to see if the end connector is bad should isolate high loss, in a doubleended test. Basic Guideline for Loss Measurements for Installed Fiber Optic Cables Connector loss: 0.75 db per mated pair Fiber loss: Multi-mode: 2.5 db/km @ 850 nm, 2.5 db/km @ 1300 nm Fiber loss: Single mode: 1.0 db/km @ 1310 nm Table 2-4 December 2000 Page 19 of 113

THE INTERMEDIATE DISTRIBUTION FRAME I. The Design Process A. The intermediate distribution frame (IDF) is the space where the horizontal cable is terminated on patch panels, 110-blocks, or connector panels, and crossconnected to the riser cable. B. The IDF supports the voice, data, and video needs of one floor of a building as opposed to an entire building or campus. It may also support other building information systems such CATV, alarms, security, audio,800mhz radio, other wireless systems and other telecommunications systems. 1. It is important to note that a BDF can be collocated with a IDF. Additional space, racks, electrical and cable management are required to support the BDF. II. The Size of the IDF A. The size of the IDF depends on its function and the size of the usable floor space it serves. Usable floor space refers to the building areas used by the occupants in their normal daily work functions. The minimum IDF sizes shown are based on providing telecommunications service to one individual work area of 100 sq. ft. B. There must be at least one IDF per floor. C. Multiple IDFs are required if the usable floor space to be served exceeds 10,000 square feet or the cable length between the work area outlet and the horizontal cross-connect in the IDF exceeds 295 feet. Minimum IDF sizes are shown in Table 3-1. D. Additional floor space must be allocated if fire alarm panels and/or building monitoring equipment are located in the IDF. E. Additional floor space must be allocated for additional applications, such as, Video Distribution cabling and equipment, etc. Floor Area Served (Square Feet) Minimum IDF Room Size (Feet) 5,000 or less 10 8 5,000 to 8,000 10 9 8,000 to 10,000 10 11 December 2000 Page 20 of 113

Table 3-1 Note: These wall lengths are the minimum acceptable. Shorter wall lengths will not allow space for equipment. III. The Location of the IDF A. Since the IDF is the focal point for many communications services, it must be designed as an integral part of the overall building. B. The IDF must be located as close as possible to the center of, and on the same floor as, the work area it serves in order to minimize the horizontal cable lengths.. C. Access to the IDF must be directly from hallways, not through classrooms, offices, or mechanical spaces. D. The IDF must be located above any threat of flooding. All water pipes transiting the room(as well as the associated plumbing fixture) must be removed or contained. E. The IDF must not be located near power supply transformers, elevator or pump motors, generators, x-ray equipment, radio transmitters, or other potential sources of electromagnetic interference. F. The IDF must not share space with electrical, janitorial, or storage facilities. G. IDFs must be stacked vertically in a multi-story building. H. When controlled access to an IDF cannot be guaranteed, free standing or wall mounted lockable distribution cabinets will be used as the IDF. See Appendix A, Specification 07 for details on these cabinets. I. The locations of the IDFs must be submitted to the project manager for inclusion in the construction drawings, and they must be annotated on the floor plan. IV. Design Requirements A. The major factors that must be considered when designing the IDF are as follows: 1. The minimum ceiling height must be 8 feet, 6 inches. 2. The doors must be a minimum of 3 feet wide and 6 feet, 8 inches tall. The doors must open outward and be lockable. December 2000 Page 21 of 113

3. The floor must be sealed concrete or tile to minimize dust and static electricity. 4. There must be continuous and dedicated environmental control (24 hours per day, 365 days per year). a) Heating, ventilation, and air conditioning sensors and control equipment must maintain the room temperature between 64 F and 90 F. b) The relative humidity must be 20% to 80%. 5. The IDF must not be equipped with a drop tile or other false ceiling. 6. The lighting in the IDF must provide a minimum equivalent of 50 footcandles when measured 3 feet above the finished floor. a) The light fixtures must be mounted a minimum of 8 feet, 6 inches above the finished floor. b) The light switches must be located inside the room. 7. All walls must be lined with Trade Size ¾-inch AC-grade plywood, 8 feet high, as measured from finished floor. Note: The plywood must be securely fastened to the wall-framing members, and painted with two coats of white fire-retardant paint. 8. The IDF must be equipped with: a) A minimum of two dedicated 3-wire 120V AC quad electrical outlets on separate branch circuits and 20-ampere rated.

THE RISER SEGMENT I. The Design Process A. The riser segment consists of the riser cable and the supporting infrastructure within a building or cluster of buildings that connect the intermediate distribution frames (IDFs) and the building distribution frame (BDF). B. The riser segment must be designed one segment at a time as illustrated in Figure 4-1, even though the riser cables may follow the same path. IDF 3.1 Segment B IDF 2.1 Segment A BDF 1.1 Figure 4-1. Riser segment. C. This section describes the policies and procedures for the following design activities: 1. The sizing of the riser cable. 2. Designing the structures to support a vertically aligned riser segment. 3. Designing the structures to support a horizontally offset riser segment. December 2000 Page 30 of 113

II. The Size of the Copper Riser Cable A. The size of the riser cable is a function of the number of basic, enhanced, and integrated outlets supported by the IDF. 1. The minimum number of copper cable pairs required for each type of outlet is as follows: basic outlets = 1.5 pairs; enhanced outlets = 2 pairs, integrated outlets = 2.5 pairs 2. Commonly available cable sizes are 50, 100, 200, 300, 600, 900 and 1200 pairs. Example: The riser cable for an IDF supporting 5 basic outlets, 50 enhanced outlets, and 4 integrated outlets would be sized as follows: Basic outlets 1.5 pair = 7.5 Enhanced outlets 2 pairs = 100 Integrated outlets 2.5 pairs = 8 Size of riser cable = 115.5 pairs In this case, the riser cable would be 200 pairs, the next larger, commonly available copper cable, above 100 pair. III. The Size of the Fiber Optic Riser Cable A. The size of the fiber optic cable is a function of the number of data outlets served by the IDF. Note: The minimum number of fiber strands for each type of IDF is shown in Table 4-1. Each IDF fiber cable shall be comprised of 50% multimode and 50% single mode fiber strands (example: 12 fiber cable with 6 multimode and 6 singlemode fiber strands) Less than 24 data outlets 12 strands = 6sm + 6mm Less than 48 or more than 24 data outlets 24 strands = 12sm + 12mm Less than 96 but more than 48 data outlets 48 strands= 24sm + 24mm More than 96 data outlets 60 strands= 30sm + 30 mm Table 4-1 December 2000 Page 31 of 113

IV. Structures to Support Vertically Aligned IDFs A. IDFs that are vertically aligned must be connected with sleeves or slots. A sleeve is a circular opening through the ceiling or floor of an IDF that allows the passage of cables and wires. A slot is similar to a sleeve except that it is a rectangular opening. B. Sleeves and slots must be positioned near a wall on which the riser cables can be supported. C. They must be located where pulling and termination will be easy, preferably on the left side of the IDF. D. Sleeves and slots must not be placed directly above or below the wall space that is used for termination fields. E. Sleeves and slots must conform to the National Electrical Code (NEC) and local fire codes. F. Sleeves and slots must not be left open after cable installation and they must be properly firestopped at all times in accordance with applicable building codes. G. Sleeves must extend a maximum of 4 inches above the floor level. Slots must have a 1-inch high curb. See Figure 4-1 for typical sleeve and slot dimensions. H. Rigid steel conduit (RSC) sleeves must be 4 inches in diameter unless a structural engineer requires a smaller size or obstructions are present. They must be fitted with plastic bushings on both ends and equipped with pull strings. I. All unused sleeves must be capped. J. In a multi-story building, grip beckets must be specified to support the riser cable s weight as it passes through the IDF.. See Figure 4-1 for typical sleeve and slot dimensions. December 2000 Page 32 of 113

Figure 4-1. Proper sleeve and slot construction. Table 4-1 lists the minimum number of 4-inch sleeves that must be used based on the total feet that the sleeves support. Total Square Feet Quantity of Sleeves Up to 50,000 3 50,000 to 100,000 4 100,000 to 300,000 5-8 300,000 to 500,000 9-12 Table 4-1 Table 4-2 lists the sizes of slots that are required based on the total square feet served by the slot. Total Usable Area Served by Slot (Square Feet) Size of Slot (Inches) Up to 250,000 6 9 250,000 to 500,000 6 18 500,000 to 1,000,000 9 20 Table 4-2 Note: The number of sleeves and/or sizes of slots must be specified prior to construction because coring holes through concrete is expensive, it creates dust, and it may cause water damage or create structural hazards. An engineer registered in the State of California must approve all structural changes and floor penetrations. December 2000 Page 33 of 113

V. Structures to Support Horizontally Offset IDFs A. IDFs that are not vertically aligned must be connected with cable trays or conduits. B. Cable trays that are used to support horizontal cabling may be used to support riser cables provided the following conditions are met: 1. The cable trays carrying capacity can accommodate the riser cables. 2. The route of the cable trays can be used or modified to accommodate the lateral run between the IDFs. 3. The riser cables conform to NEC Article 800-3(b)(1), NEC Article 800-3(b)(3), and comply with the State of California fire codes as interpreted by the State Fire Marshal s department. 4. The riser cables are UL Listed Type CMP or OFNP if they are placed in air-handling plenums without conduit. Refer to Appendix A Specification 05 for cable tray specifications. C. Conduit will be used to route the riser cables between the IDFs if cable trays are not used to support the horizontal cabling. Conduit paths are tightly controlled pathways that must be coordinated with other trades during construction or remodeling. 1. The conduit will be rigid steel conduit (RSC), EMT, or intermediate metallic conduit (IMC), 4 inches in diameter. See Appendix A Specification 08 for details on conduit fill for riser cables. 2. The conduit will be grounded at each end. 3. The conduit will be installed with a pull string and the ends will be bushed to protect the cable. 4. Conduits that enter the IDF must be placed near the corner and as close as possible to the wall where the backboard is mounted to allow for proper cable racking and to minimize the cable route inside the IDF. 5. Conduit located in the ceiling must protrude into the IDF 1 to 2 inches and above 7½ feet above the finished floor. Conduit will not turn down. December 2000 Page 34 of 113

Note: A 1-inch conduit must be dedicated from the IDF to a sealed junction box on the roof of the building for use as an antenna access point. This conduit must be grounded using a path other than the telecommunications ground provided in the IDF. D. Listed below are the steps needed to plan conduit runs in the riser segment: 1. Identify on the floor plans the IDFs that will be supported using conduit. 2. Determine the number of conduits required. This number is the same as the number of sleeves required if the IDFs had been vertically stacked. 3. Sketch the proposed route of the conduit on the floor plan. 4. Determine if any pull boxes are needed along the conduit run. a) Pull boxes are required in sections of conduit that are 100 feet or more in length or that contain more than two 90 bends. Pull boxes must not be used in lieu of a bend. b) Cables must feed straight through a pull box. See Appendix A Specification 09 for details on installing and selecting the proper size of pull boxes. 5. Notify the project manager of the locations and sizes of the pull boxes for inclusion in the mechanical or electrical designs. 6. Annotate on the floor plan the locations and sizes of the pull boxes. E. The riser cable is labeled based on a cable number assigned by Communications Resources. The cable pair numbers will also be included in the label. December 2000 Page 35 of 113

THE BUILDING DISTRIBUTION FRAME I. The Design Process B. The building distribution frame (BDF) is the room that houses the telecommunications equipment that meets the voice, data, and video needs of an entire building. This equipment may include Private Branch Exchange (PBX), switching nodes, local area network hubs, and video distribution equipment, and/or network routers. C. The BDF contains cross-connect facilities for terminating cables and for connecting the horizontal and riser segments to each other and to telecommunications equipment. The BDF may also support other building information systems such CATV, alarms, security, audio, and other telecommunications systems. 1. It is important to note that an IDF can be collocated with a BDF. Additional racks, electrical and cable management are required to support the IDF. The quantity of racks is dependant upon the quantity of NAMs that must be supported. D. Whether this space is separated or combined with the building service entrance, it is, by almost every definition, a specialized area. This room will house sensitive electronic components that will generate heat 24 hours a day, 365 days a year and must be cooled to maintain operating performance. E. The air handling system for equipment rooms must be designed to provide positive air flow and cooling even during times when the main building systems are shut down. This may require separate air handlers and/or small stand-alone cooling systems that are thermostatically controlled in this space. If this room is to be used as a Area Distribution Facility (ADF), the air handling system should be connected to the building s backup power generation system. II. The Size of the BDF A. The size of the BDF depends upon the size and variety of the equipment to be installed and the size of the area that the room will serve. 1 The BDF must provide enough space for all planned equipment and cables, including any environmental control equipment, power distribution/conditioners, and uninterrupted power supply systems that will be installed there. December 2000 Page 36 of 113

2. The BDF must also provide space for access to the equipment for maintenance and administration, and for equipment changes with minimal disruptions. B The minimum size of the BDF can be determined as follows: 1. In a BDF dedicated to Communications Resources (if the environment allows) open equipment racks a 19 x 84 rack will be utilized with 6 vertical cable management on each side. This equates to a 32 equipment bay. A minimum of three bays will be installed in any size building with the x wall a minimum of 10 feet. 2. A minimum of 2 feet shall be left at the end of the row of equipment bays. A minimum of 5 feet between walls and equipment bays will allow space for wall mounted copper cable terminations and the required 36 distance from equipment for work space. 3. In larger size buildings requiring additional rows of equipment bays, the bays shall be lined up in rows with 5 feet between the rows and walls. Use the formula below to determine the minimum square footage. The number of equipment bays required will determine the x dimension. 4. For one row of equipment bays hold the x dimension to 10 feet, for two rows of equipment bays hold the x dimension to 16 feet, and for three rows of equipment bays hold the x dimension to 22 feet. III. The Location of the BDF A. The BDF must be located as close as possible to the building entrance so that it is accessible for the delivery of large equipment. B. The BDF must not be located in any place that may be subject to water or steam infiltration, humidity from nearby water or steam, heat, and any other corrosive atmospheric or environmental conditions. C. The BDF must not be located near electrical power supply transformers, elevator or pump motors, generators, x-ray equipment, radio transmitters, radar transmitters, induction heating devices, and other potential sources of electromagnetic interference. F. The BDF must not share space in or be located near electrical closets, boiler rooms, washrooms, janitorial closets, and storage rooms. G. The location of the BDF must be submitted to the project manager for inclusion in the construction drawings, and it must be annotated on the floor plan. December 2000 Page 37 of 113

IV. Design Requirements A. The major factors that must be considered when designing the BDF are as follows: 1. The minimum ceiling height must be 8 feet, 6 inches. 2. Ceiling protrusions must be placed to assure a minimum clear height of 8 feet 6 inches to provide space over the equipment frames for cables and suspended racks. 3. The doors must be double doors that are 6 feet wide by 7 feet, 6 inches tall. The doors shall be keyed to campus standards for access by Communications Resources only. They must open outward and be lockable. Access shall allow for future equipment changes. 4. The floor must be sealed concrete or tile to minimize dust and static electricity. 5. There must be continuous and dedicated environmental control (24 hours per day, 365 days per year). a) Heating, ventilation, and air conditioning sensors and control equipment related to the environment within the BDF must be located in the BDF. b) The room temperature must be maintained between 64 F and 80 F. c) The relative humidity must be 30% to 55%. d) Heat load is 5,000 BTUs per hour per electronic cabinet, equipment rack. e) A positive air pressure differential must be maintained with respect to surrounding areas. 6.

The BDF must be provided with an electrical ground on a 4-inch or larger busbar as defined by NEC Article 250-71(b). a) The busbar must be mounted 6 feet, 6 inches above the finished floor if ladder racking is included in the design. If ladder racking is not part of the design, the busbar must be located near, but not behind, the riser sleeves between floors. b) This grounding bar must be connected to a main building ground electrode, reference ANSI/EIA/TIA-607. 10. Acoustic noise levels in the BDF must be maintained to a minimum by locating noise-generating equipment outside the BDF. 11. Additional equipment such as fire alarm panels and/or building monitoring devices must not be housed in the BDF. Separate space for these services can be provided as part of the electrical room or in a separate space. V. Termination Hardware Requirements in the BDF December 2000 Page 39 of 113

THE CAMPUS SEGMENT I. The Design Process The campus segment consists of the cables and structures needed to inter-connect BDFs and area distribution frames (ADFs). It includes underground (in conduit) cables, direct buried cables, splice boxes, manholes, pull boxes, aerial cables, pole lines, outside terminals, and support structures. The campus segment must be designed and installed to ANSI/EIA/TIA-758 Specifications for Outside Plant Construction. A. This section describes the policies and procedures for the following design activities: Identifying cable routes from building to building, selecting cable distribution methods, determining the underground and direct buried cable requirements, identifying the types of cable used in the campus segment, determining splice boxes, manholes, and pull box requirements, determining aerial cable requirements, satisfying electrical protection and bonding/grounding requirements. II. Cable Routes A. The following steps must be taken to identify the cable routes between new buildings and major building renovations. 1. Obtain a photocopy of the campus layout map. 2. Determine where the cable entrance point is for each building. 3. Sketch the cable route from the starting point to the terminating point in the buildings to be served on the campus layout map. 4. Note any obstacles, existing cable facilities, or other underground utilities on the campus layout map. 5. Note if right-of-way permits or easements are required. 6. Review proposed cable route to determine if conditions exist that require environmental impact applications. Identify sources of future cable maintenance problems. December 2000 Page 47 of 113

III. Cable Distribution Methods A. Communications Resources Systems Engineering & Development, and appointed layout engineers must be contacted to determine the best cable distribution method along the proposed cable route. The method may be one or a combination of underground (in conduit), direct buried, directional boring, or aerial. 1. An underground cable system consists of cables placed in buried conduits, using manholes and/or pull boxes for splices in large runs. The conduit runs from the building entrance location to a pole, pedestal, or manhole. 2. A direct buried cable system consists of cables and associated splices directly placed in the earth. The trench runs from the building entrance location to a pole, pedestal, or manhole. 3. In aerial cable systems telecommunications cable is installed on aerial supporting structures such as poles, sides of buildings, and other above ground structures. Note: An underground cable system must be used if a conduit route is available between buildings. IV. Underground (In Conduit) and Direct Buried Cable Requirements A. The California Public Utilities Commission (CPUC) regulates underground and direct-buried cable placement specifications. Note: All underground conduit applications and direct buried construction at UC Davis must conform to CPUC s General Order Number 128, Section IV. B. Underground (in conduit) and direct buried cable projects must be worked from engineering drawings approved by the Manager Systems Engineering & Development, Communications Resources. These drawings 4 must include the following information: 1. Details of typical trench cross sections showing cable and duct locations in the trench, clearances from final grade, backfill materials and depths, pavement cutting information, and compacting requirements for both paved and unpaved areas. 2. Construction notes applicable to the work being performed. 4 Reference: UC Davis Campus Standards & Design Guide for drawing content pages, 29, 30, & 31 dated June 2000. December 2000 Page 48 of 113

3. A scale drawing showing location ties to existing structures, cable, conduit, utility boxes, and any conflicting substructures and profile drawings of congested areas where vertical and horizontal separation from other utilities is critical during cutting and placing operations and any other areas as requested by UC Davis. 4. A legend explaining symbols of all relevant structures and work operations. 5. Cable types, counts, and directions of feed. 6. Conduit types, dimensions, and wall-to-wall measurements when used with pull boxes, splice boxes, manholes, and BDFs. 7. Manhole drawings showing cable-racking information, applicable cable counts, conduit assignments, splicing details, north point arrows, and street names. Manhole drawings must be consistent with UC Davis Communications Resources standards. C. All cables entering a building must conform to the bonding and grounding requirements listed in NEC Articles 250 and 800. D. Warning tape containing metallic tracings must be placed a minimum of 18 inches above the buried cable to minimize any chance of an accidental dig-up. The American Public Works Association has adopted the color orange for the telecommunications cables. Refer to Specification 10 for details on underground conduit requirements and conduit sizing. E. The minimum depth of a trench must allow 24 inches of cover from the top of the cable to final grade. Local underground utilities must be contacted, a Underground Service Alert (USA) call number receipt (ticket) must be present and on site during any construction and utilities located before digging to locate all subsurface facilities such as power, gas, water, and outdoor lighting. Table 6-1 shows the vertical or horizontal separations that must be maintained between telecommunications facilities and other facilities sharing a common trench. December 2000 Page 49 of 113

Adjacent Structure Power or other foreign conduit Minimum Separation 3 inches of concrete or 4 inches of masonry or 12 inches of well-tamped earth Pipes (gas, oil, water, etc.) 6 inches when crossing 12 inches when parallel Railroad crossings (except street railways) 5 feet below top of rail 12 feet from the nearest rail if terminating on a pole 7 feet from the nearest rail if terminating on a pole at a siding Street railways 3 feet below top of rail Table 6-1. See Figures 6-1 and 6-2 for typical trench cross-sections. Figure 6-1. Trench cross-section for underground and direct buried placement in paved areas. December 2000 Page 50 of 113

Figure 6-2: Trench cross-section for underground and direct buried placement in paved areas. V. Cable Types A. UC Davis recognizes two types of cable for outside use in the campus segment: copper cable and fiber optic cable. 1. Filled polyethylene-insulated conductor (PIC) cable must be used for underground and direct buried copper cable. Filled cable preserves the integrity of the cable by providing physical protection against moisture penetration and seepage. a) Direct buried cable requires an armored sheath to resist rodent and penetration type damage. b) PIC cables must be marked with cable length, cable code, date and location of manufacture, and manufacturer. c) The following standard designations for copper exchange cable have been assigned by the Rural Utilities Services (RUS): (1) PE-39 refers to filled cable with solid insulation for directburied applications. (2) PE-89 refers to filled cable with an expanded insulation for direct-buried applications. December 2000 Page 51 of 113

25.1. The cable jacket of a cable containing two different fiber types (hybrid construction) shall be marked to indicate quantity of each fiber type, identity of each fiber type and the fiber sequence. 26. If the initial marking fails to meet the specified requirements (i.e., improper text statement, color, legibility, or print interval), the cable may be remarked using a contrasting alternate color. The numbering sequence will differ from the previous numbering sequence, and a tag will be attached to both the outside end of the cable and to the reel to indicate the sequence of remarking. The preferred remarking color will be yellow, with the secondary choice being blue. 27.

Splice boxes and manholes are needed where maximum cable reel lengths are exceeded, at the intersection of main and branch conduit runs, and at other locations where splices are needed in a conduit system. 1. UC Davis has accepted the general sizing guidelines for splice boxes and manholes used by Pacific Bell Telephone. These guidelines are based on ultimate requirements. 2. Splice boxes and manholes must meet the weight-bearing standards required under CPUC s General Order Number 128. 3. Manholes, hand-holes, and subsurface equipment enclosures in street areas, which are subject to vehicular traffic, must be constructed to withstand H-20-44 highway loading as designated by the American Association of State Highway Officials. Floors of manholes must meet the requirements of Public Utilities Code, Section 8054. 4. Precast manholes must be used whenever possible. Site-cast manholes may be used when the size required exceeds precast sizes, obstructions prohibit placing precast manholes, manholes must be rebuilt, or a custom design is required. 5. Manholes must be sized to meet the maximum conduit requirements and be located to optimize the use of the associated conduit routes. 6. All conduits must be sealed in a manhole system to prevent water entry. 7. The strength of concrete used for manholes must be at least 3,500 psi. December 2000 Page 56 of 113

Specification 10 Conduit for Underground Cabling Telecommunications System Design Segment Horizontal IDF Riser BDF Campus These specifications provide a minimum configuration that must be used when planning new construction or major remodeling of an existing facility. Communications Resources must be consulted during the early utilities planning phase of the project since each site may have technical requirements requiring a modification of these specifications. Conduit must be PVC Schedule 40, corrosion-resistant plastic with a 4 inch inside diameter. Conduit must be provided with a 12-gauge steel wire or equivalent pull wire with a minimum of 200 pound pulling tension. All unused entrance conduits must be capped/plugged and installed with pull strings. Conduit stubs entering the building must extend beyond the foundation landscaping. All conduit ends adjacent to the building must be flagged for easy identification. Conduit entering from a below grade point must extend 4 inches above the finished floor in the BDF. Conduit entering from ceiling height must terminate 4 inches below the finished ceiling. Conduit must be securely fastened to the building to withstand a typical placing operation performed by the service provider. The area around the conduit entrance must be free of any construction, storage, or mechanical apparatus. All metallic conduit and sleeves must be reamed, bushed, and capped when placed. Metal sleeves through foundation walls must extend to undisturbed earth to prevent shearing. December 2000 Page 84 of 113

The top of the conduit must be buried at least 24 inches below the ground surface. Warning tape equipped with a metallic tracer shall be placed 18- inches above top of conduit bank. Underground conduit must be terminated at the designated property line with a minimum cover of 24 inches. Conduit must be encased in concrete when the following conditions exist: minimum conduit depth cannot be attained, conduits must pass under roads, driveways, or railroad tracks, or bend points might be subject to movement. Reinforcing bars within the concrete must be used at any location subject to potentially extreme stress. All entrance conduits must be securely fastened to the building to withstand a typical placing operation performed by the service provider. The area around the conduit entrance must be free of any construction, storage, or mechanical apparatus. The inside-the-building end of the conduit must be sealed to prevent rodents, water, or gases from entering the building There must be no more than two 90 bends between pulling points on all entrance cables. All bends must be long, sweeping bends with a radius not less than 6 times the internal diameter of conduits 2 inches or smaller, or 10 times the internal diameter of conduits larger than 2 inches. Conduit must be positioned on the field side of the poles (the side that is protected from the normal flow of traffic). Sizing Underground Conduit The quantity and size of underground entrance conduits are based on the anticipated number and type of telecommunications circuits that will be brought into the building. UC Davis requires 2 entrance pairs per 100 square feet of usable office space. The following table shows the data for determining the quantity and size of underground entrance conduits. Telephone Entrance Conduits Required Pairs 1-1000 1each 4-inch conduit + 2 spare 4-inch conduits 1001-2000 2 each 4-inch conduits + 2 spare 4-inch conduits 2001-3000 3 each 4-inch conduits + 2 spare 4-inch conduits 3001-5000 4 each 4-inch conduit + 2 spare 4-inch conduits 5001-7000 5 each 4-inch conduits + 2 spare 4-inch conduits 7001-9000 6 each 4-inch conduits + 2 spare 4-inch conduits Note: Two spare 4-inch conduits must be brought into every building in addition to the quantities specified above.

Specification 11 Electrical Protection, Bonding/Earthing Telecommunications System Design Segment Horizontal IDF Riser BDF Campus These specifications provide a minimum configuration that must be used when planning new construction or major remodeling of an existing facility. Communications Resources must be consulted during the early utilities planning phase of the project since each site may have technical requirements requiring a modification of these specifications. Electrical protection must be provided for cables that are subject to lightning, power contact, ground potential rise, or induction. The minimum protection is a tri-element gas module device. Cables exposed to power sources must be provided with sneak current protectors which will protect cables against voltage and power surges by interrupting the current or by grounding the conductors. Ground systems must conform to the NEC specifications. Approved ground systems are: building entrance power ground from transformer single point building steel (the metal frame of the building itself ) building footing (a concrete-encased electrode near the bottom of the building's foundation) ground ring (20 feet or more of bare copper wire in direct contact with the earth-it encircles the building) metallic power service conduit, enclosure, or grounding electrode ground rod or pipe Equipment single point grounds must be grounded to the building grounding systems as defined in ANSI/TIA/EIA-607 (1994) Commercial Building Grounding and Bonding Requirements for Telecommunications December 2000 Page 86 of 113

. Riser cables must be grounded at the point of origination and at any floor in which pairs leave the cable sheath. Riser cable sheaths must be bonded to approved grounds in the IDFs and the BDF. Lateral cables must be bonded to approved grounds in the IDFs. Cable sheaths of cables entering a building must be bonded to an approved ground at the building entrance location. Protector panels will be wired to an approved ground by the straightest and shortest means. The NEC requires a listed primary protector (such as the AT&T 188B1-100, 25, 50 or the CIRCA Equivalent with 4B1E-W Protector Module) at both ends whenever an aerial communications cable is routed across a street and whenever aerial or underground campus circuits may be exposed to accidental contact with power conductors operating at over 300 volts. TGB3.1 Equipment Exposed refers to an outdoor communications cable s susceptibility to electrical power system faults or to lightning or other transients. A cable is also considered electrically exposed if any of its branches or individual circuits is exposed. A lightning exposure guideline is included in the NEC Section 800-30(a). It states that inter-building circuits are considered to have exposure to lightening unless cable runs are 140 feet or less, buried with a properly grounded shield. The NEC also states that the shield must be bonded to the building s ground electrode system at each end. TGB2.1 TMGB Grounding Electrode System Equipment #6 insulated copper conductor Equipment NEC Article 100 and Section 250-70 define bonding as the permanent joining of metallic parts to form an electrically conductive path that will assure electrical continuity and the capacity to conduct safely any current that is likely to be imposed. Bonding conductors are not intended to carry electrical load currents under normal conditions, but must carry fault currents so that electrical protection (circuit breakers) will properly operate. December 2000 Page 87 of 113

A #6 AWG copper conductor will be used to bond the communications components to the ground. A larger conductor will be used if the ground source exceeds 5 ohms. The electrical contractor must provide access to a bonding connection at the electrical service ground during new construction (NEC 250-71(b)). A telecommunications main grounding busbar (TMGB) must be specified in the BDF with an approved ground connector back to the electrical service ground point. A telecommunications grounding busbar (TGB) must be specified for each IDF in the building. Each TGB will have a #6 AWG conductor back to the TMGB. In a renovation or remodeling project where a suitable ground to the electrical service ground is not available, a grounding electrode will be installed in accordance with the NEC Section 250-83. Note: a metallic water pipe connected to a utility water distribution system is no longer the first choice for a grounding electrode. The NEC recommends the that a ½ inch diameter, 5 foot ground rod be used. Communications bonding relies on short direct paths that have minimum resistive and inductive impedance: Bonding conductors must be routed with minimum bends or changes in direction. Bonding connections must be made directly to the points being bonded, avoiding unnecessary connections or splices. December 2000 Page 88 of 113

APPENDIX B Reference Materials Following is a listing of reference materials on telecommunications infrastructure. ANSI/TIA/EIA-568-A-1995, Commercial Building Telecommunications Cabling Standard, provides rules and guidelines for the physical design of a cabling infrastructure that supports voice and data transmissions in a multi-vendor environment. The standards specify a cabling system with a physical star topology. This topology provides economic benefits in terms of initial cabling costs, ongoing maintenance, and administration costs. The standards specify copper and fiber optic cable by parameters that determine performance. They also identify connectors and their pin assignments to ensure inter-connectivity. The standards specify maximum allowable distances within the various elements of a cabling system. Include latest additions, corrections or Addendums. ANSI/EIA/TIA-569-A 1998, Commercial Building Telecommunications Pathways and Spaces, describes design and construction practices for pathways and spaces to support telecommunications media and equipment within and between buildings. Standards are given for the design of horizontal and work area pathways, building entrance facilities, telecommunications closets, and equipment rooms. Include latest additions, corrections or Addendums. ANSI/TIA/EIA-606-1993, Administration Standard for the Telecommunications Infrastructure of Commercial Buildings, provide guidelines for labeling and administering the telecommunications equipment space, cable pathways, grounding, cabling, termination, and other components that comprise a structured cabling system. The administration of telecommunications includes documentation of telecommunications outlet boxes, connectors, cables, termination hardware, patching and cross-connect facilities, conduits, other cable pathways, telecommunications closets and other spaces. These standards specify a telecommunications infrastructure administration scheme that is independent of applications. Use of these standards results in a cabling system that is well documented and easily managed by the administrator over the life cycle of the building. ANSI/TIA/EIA-607-1994, Commercial Building Grounding and Bonding Requirements for Telecommunications, describes a standard method for distributing signal ground throughout a building. These standards provide the requirements for a ground reference for telecommunications systems within the telecommunications entrance facility, the telecommunications closet, and the equipment room. They also specify the requirements for bonding and connecting pathways, cable shields, conductors, and hardware at telecommunications closets, equipment rooms, and entrance facilities. The grounding and bonding approach is consistent with the cabling topology specified in ANSI/TIA/EIA-568-A-1995 and installed in accordance with ANSI/EIA/TIA-569-1990. December 2000 Page 89 of 113

ANSI/TIA/EIA-758 Customer-Owned Outside Plant Telecommunications Cabling Standard (April 1999) ANSI/TIA/EIA-758-1 Addendeum No. 1 to TIA/EIA-758 Customer-Owned Outside Plant Telecommunications Cabling Standard (March 1999) This Standard specifies minimum requirements for customer-owned OSP telecommunications facilities in a campus environment. The standard specifies the cabling, pathways and spaces to support the cabling. Customer-owned OSP cabling extends between separated structures including the terminating connecting hardware at or within the structures. The OSP pathway includes the pathway through the point of entry into the building space. Customer-owned OSP pathways may include aerial, direct-buried, underground (e.g., duct), and tunnel distribution techniques. Customer-owned OSP pathways and spaces specified by this Standard are intended to have a useful life in excess of forty (40) years. The OSP cabling specified by this Standard is intended to support a wide range of applications (e.g., voice, data, video, alarms, environmental control, security, audio, etc.) on commercial, industrial, institutional and residential sites. The customer-owned OSP cabling specified by this Standard is intended to have a useful life in excess of thirty (30) years. This standard applies to all campuses, regardless of the size or population. Underwriters Laboratories (UL), LAN Cable Certification Program. Test products to verify that performance meets or exceeds industry standards. The UL tests the electrical shock, flame spread, and smoke production characteristics of cables. The UL also tests cables for transmission properties. National Electrical Code (NEC) Sections 250 and 800, provide a set of codes governing items such as voltage limits, transmission media conductor size, overvoltage protection requirements, fire resistance of cables, and cabling methods. It is important to check with local governing bodies to determine if their codes supersede the NEC articles.

APPENDIX F SUPPORTING STANDARDS FOR IN-BUILDING RADIO COMMUNICATION SYSTEM AMPLIFICATION Supporting Standards for In-Building Radio Communication Systems Amplification. 1.0 Purpose. This purpose of this document is to establish the policies and procedures regarding the needs assessment, specifications, type, cost evaluation, testing and acceptance of an in-building radio system required in new campus buildings. 2.0 General Radio Communications Coverage. All buildings require the capability to support radio communications of the local public safety entities (Fire, Police etc.) Since each building is unique in its location, construction, and interior design, this document provides guidance in support of the formal Radio System Coverage Evaluation / In-Building Radio Communication Systems which requires consideration of funding appropriations for specific radio system coverage of each newly constructed facility and/or consideration for existing facilities that may be impacted by the new construction. In many cases, a placeholder is to be used for in-building amplification costs; based on historical data, a recommendation of $35,000 should be used for capital projects exceeding 5000 square feet or multi-level structures. (Refine estimate during cost evaluation) 2.1 Definitions. BTS Base Transceiver Station also known as the donor site. dbm db, decibels, in milli-watts. A unit of measure for RF signal level. Distributive Antenna A system of non-radiating cable connected to an array of passive antenna. Donor - Base Transceiver Station also known as the donor site. Donor channel The frequency in which the donor site transmits digital control information Grade of Service Typical service is stated as 95% coverage, 95% calls Received and Transmitted at Circuit Merit Level 3 (CM3). 6 6 The California Governor s Office of Emergency Services (OES) Auxiliary Communications Service (ACS) uses a "circuit merit" rating as a reporting system for transmission quality. CM5 = Completely clear, each word fully understood. CM4 = Clear with slight amount of static and or interference. Each word is understood. CM3 = Static and or interference present, but the bulk of the transmission is understood without having to be repeated. Deemed to be the margin of acceptable, professional communication. CM2 = Static and interference are prevalent and words are missing. December 2000 Page 107 of 113

Fiber Optic Optical transport of radio signals over fiber optic cable. Off Air Repeater A repeater that receives frequencies from and antenna and amplifies and retransmits these frequencies. NPSPAC National Public Safety planning and Advisory Committee FCC Federal Communications Commission 3.0 General Policy Except as otherwise provided, no person shall, erect, construct, change the use of or provide an addition of more than 20% to, any building or structure or any part thereof, or cause the same to be done which fails to support adequate radio coverage for the clients of the University of California, Davis 800 MHz Trunked Communications System, (including but not limited to Firefighters, Police Officers, or Emergency Response Personnel). For purposed of this section, adequate radio coverage shall include all of the following: A minimum signal strength of -95 dbm available in 95% of the area of each floor of the building or structure when transmitted from the campus Central Transceiver of the University of California, Davis 800 MHz Trunked Communications System; 7 A minimum signal strength of -95 dbm received at the campus Central Transceiver of the University of California, Davis 800 MHz Trunked Communications System when transmitted from 95% of the area of each floor of the building; The frequency range which must be supported shall be 821-823 MHz and 866-868 MHz; and A 100% reliability factor. 4.0 Amplification Systems Allowed. Buildings and structures which cannot support the required level of radio coverage shall be equipped with either (A) an internal multiple antenna system with or without FCC type accepted bi-directional 800 MHz amplifiers as needed or (B) radiating cable system (leaky coax). If any part of the installed system or systems contains an electrically powered component, the system shall be capable of operating on an independent battery and/or generator system for a period of at least twelve (12) hours without external power input. The battery system shall automatically charge in the presence of an external power input. If used, bi-directional amplifiers shall include filters to reduce adjacent frequency interference at least 35 db below the NPSPAC band. The filters shall be tuned to 825 MHz and to 870 MHz so that they will be 35 db below the NPSPAC frequencies of 824 MHz and 869 MHz respectively. Other settings may be used provided that they don't attenuate the NPSPAC frequencies and further provided that they are not more than one MHz from the NPSPAC frequencies. 5.0 Evaluation Process. CM1 = Signal is barely evident and the words are not understandable. CM0 = Nothing heard 7 When measuring the performance of a bi-directional amplifier, signal strength measurements are based on one input signal adequate to obtain a maximum continuous operating output level. December 2000 Page 108 of 113

The evaluation process for determining the need for in-building amplification is conducted in a minimum of three phases: Pre-construction, construction, and acceptance/implementation. 5.1 Pre-construction Phase. Before the construction of the new building, basic information can be gathered to begin the process of determining the need, type and actual implementation of augmentation to the radio system. In most cases, the following information must be known to properly design and cost estimate an in-building radio system. 5.1.1 New Building Information. Type/Size of building single story, multi-level, square foot If multi-level, number of stories Orientation of building above/below ground, line of sight Construction of the outer and inner walls. Plaster, drywall, brick. Proposed equipment locations Equipment rooms, cableways, conduits. Building location - Longitude and latitude coordinates. Local building code requirements and special requirements. Building Blueprints or drawings. 5.1.2 Existing System Information. BTS location Longitude and latitude coordinates. Donor channel frequency Specific digital channel to enhance radio coverage. Grade of Service required meeting objective. Type of subscriber unit. Number of channels and their frequencies. Signal strength of donor site at the building location. With the information above, the following steps can establish determining the potential need for an inbuilding radio system. 5.1.3 Needs Determination - Signal Strength Measurements. At the planned construction site, measure (or have measured) the signal strength of the donor control channel: If the signal strength of the donor is 95 dbm or less on the outside of the building, the probability of additional in-building coverage is high. If the signal strength of the donor is greater than 95 dbm, determine the expected signal strength of the donor by subtracting the sum of the interior losses due to walls, doors and windows from the ambient signal outside the building. (See Table 1) If a signal strength of -95 dbm or greater is calculated at the inner most point of the building, an in building system may not be required. If the signal strength is calculated at 95 dbm or less, an in-building system is warranted. To determine signal strengths for specific areas on campus and evaluate the impact of the facility on existing structures, consult the latest UC Davis Outdoor RF Survey report. If determined that In-building amplification is required for either the proposed site or existing structures impacted by the proposed construction, provide placeholder in budget for cost of communication system based on results of the above. 5.2 Construction Phase. As the construction progresses, refinements to the placeholder budget should be made to ensure adequate funds are available to cover the cost of providing in-building amplification to the new facility and to re- December 2000 Page 109 of 113

evaluate the impact on existing structures. Re-visiting the specifications from the initial evaluation will fine-tune the proposed cost line item. 5.3 Acceptance / Implementation Phase. Using criteria from Section 7, the Project Manager will accept the In-Building amplification measurements, ensuring they are within design specification. The budget line item may be closed out upon final acceptance. 6.0 Cost Evaluation / RFSP. Once a determination has been made that in-building amplification is required for the proposed facility or as an augmentation to existing facilities impacted by the new facility, cost estimating an in building coverage system is mostly an academic process. The first step in this process is to determine if the system should be fiber based or an Off- air system. Each system has it own unique advantages and disadvantages. (Table 2 identifies several cost considerations that may be quantified in the planning stage) 6.0.1 Fiber Optic Based System. If there is dark fiber present or can be economically installed from the Network Operations Center (NOC) to the proposed building, then a fiber based solution is viable. Fiber based systems have typically better performance than an off-air system. This is due to the reduction of out of band interference that an off-air system is exposed. Fiber based systems are typically more expensive than off air system, but once installed are easily expanded and maintained. Fiber systems typically have multiple antennas that transmit low power RF (0 dbm typical). An antenna transmitting 0 dbm can cover approximately a 75 foot radius. Therefore, by breaking up the coverage area into 75 foot sections and multiplying the number of section by the cost per antenna installed can give you an approximate system price. 6.0.2 Off Air Repeater. If dark fiber is not present or too expensive to route to the building, in building coverage can be provided through the use of Bi-Directional Amplifiers and distributed antenna system or leaky feeder radiating cable. Off Air Repeater systems are simple and reliable and typically cost less than fiber-based solutions. They are however, susceptible to interference caused by large level signals that are close to the pass band of the amplifier. Extra RF filtering can be engineered into the system design to reject the unwanted signals. Typical applications have a central head end amplifier, which drives the distributed antenna or leaky feeder cable and the remainder of the antenna system. Adding the cost of the amplifier installed plus the cost of the distributed cable system can determine a budgetary cost estimate of an Off-Air Repeater system. 3 6.1 Vendor Request. Request for Survey and Proposal (RFSP) should be created to provide to multiple wireless system vendors. The format of the RFP can be mandated or left open to each vendor. However, the RFSP should at the minimum include the following sections: Cover Letter stating overall system price Company Capabilities Statement of Work System Description 3 NOTE: Radiating cable is typically used in narrow spaces such as tunnels and hallways. This is due the high coupling loss between the radiating cable and subscriber unit. As well, radiating cable has limited propagation and poor wall penetration characteristics. December 2000 Page 110 of 113

System Block Diagram General Schedule Turnkey Pricing 4 Conditions of Quotation Acceptance Test Plan (ATP) Maintenance, Service and Warranty The RFSP should clearly state the areas where coverage is needed, the grade of service expected (GOS), and construction schedule of the building in process. Additionally, the RFP should include the information gathered in the pre-construction assessment phase of this policy. 6.2 Testing and Acceptance. Once implemented, the RF coverage system should be tested via the pre-determined Acceptance Test Plan (ATP). The ATP should include personnel from Information and Educational Technology, Police, Fire, Safety and Vendor. A walk through test should be completed and any discrepancies noted and resolved by the vendor. 7.0 Acceptance Test Plan (ATP). When an in-building radio system is required, and upon completion of project installation, it will be the Project Manager s responsibility to have the radio system tested to ensure that two-way coverage on each floor of the building are within General policy requirements as prescribed below: Each floor of the building shall be divided into a grid of approximately twenty (20) equal areas. The test shall be conducted using a Motorola MTS 2000, or equivalent, portable radio, talking through the campus Central Transceiver of the University of California, Davis 800 MHz Trunked Communications System. o A spot located approximately in the center of a grid area will be selected for the test. o The radio will be keyed to verify two-way communications to and from the outside of the building through the campus Central Transceiver. o Once the spot has been selected, prospecting for a better spot within the grid area will not be permitted. Each grid area will be tested for transmission/reception; minimum signal strength of 95 dbm. If signal strength fails to meet the requirement, the grid area shall be marked as a fail. A maximum of two (2) nonadjacent areas will be allowed to fail the test. In the event that three (3) of the areas fail the test, in order to be more statistically accurate, the floor may be divided into forty (40) equal areas. o In such event, a maximum of four (4) nonadjacent areas will be allowed to fail the test. o After the forty (40)-area test, if the system continues to fail, the project Manager shall have the system altered to meet the 95% coverage requirement. The gain values of all amplifiers shall be measured and the test measurement results shall be kept on file with Communications Resources, a Division of Information and Educational Technology, so that the measurements can be verified each year during the annual tests. In the event that the measurement results became lost, the building owner will be required to rerun the acceptance test to reestablish, the gain values. 8.0 Additional System Testing Communications Resources will periodically test in-building amplification systems. Results of the testing will be compared to designed specifications and corrective action taken if required maintaining the system within the desired design specification. 4 Overall project management of the implementation of an in building coverage system should be offered and included in the turnkey proposal submitted.

8.1 Qualifications of Testing Personnel. Communications Resources shall be responsible for conducting or contracting system testing. All tests shall be conducted, documented and signed by a person in possession of a current FCC license, or a current technician certification issued by the Associated Public-Safety Communications Officials International (APCO) or the Personal Communications Industry Association (PCIA). All test records shall be retained on the inspected premises and a copy submitted to Communications Resources and to the Police/Fire Department officials. 8.2 UC Davis Outdoor RF Survey Report. At the discretion of Communications Resources, but no less than semi-annually, the campus shall conduct an Outdoor RF Survey mapping the campus footprint for RF energy. The report should specify specific frequencies, coverage with relative signal strength highlight those areas of signal strength below standards. 8.3 Annual Tests. When an in-building radio system are installed, Communications Resources shall test all active components of the system, including but not limited to amplifiers, power supplies and backup batteries, a minimum of once every twelve (12) months. Amplifiers shall be tested to ensure that the gain is the same as it was upon initial installation and acceptance. Backup batteries and power supplies shall be tested under load for a period of one (1) hour to verify that, they will properly operate during an actual power outage. If within the one (1) hour test period, in the opinion of the testing technician, the battery exhibits symptoms of failure, the test shall be extended for additional one (1) hour periods until the /testing technician confirms the integrity of the battery. All other active components shall be checked to determine that they are operating within the manufacturer's specifications for the intended purpose. 8.4 Five-Year Tests. In addition to the annual test, Communications Resources shall perform a radio coverage test a minimum of once every five (5) years to ensure that the radio system continues to meet the requirements of the original acceptance test. The procedure set forth above shall apply to such tests. 8.5 Field Testing. Police and fire personnel, after providing reasonable notice to Communications Resources, shall have the right to enter property to conduct field-testing to be certain that the required level of radio coverage is present. Discrepancies from field-testing and recorded tests shall immediately be brought to the attention of Communications Resources. Communications Resources will provide corrective action in response to reported discrepancies. December 2000 Page 112 of 113
