1 TM Hotwire POTS Splitter Central Office Installation Instructions Document Number 5020-A2-GN10-30 About the Hotwire POTS Splitter The Hotwire System enables simultaneous high-speed digital data access and analog voice service over the same twisted-pair telephone line. The simultaneous access to RADSL (Rate Adaptive Digital Subscriber Line) or MVL (Multiple Virtual Lines) and POTS (Plain Old Telephone Service) requires the installation of a POTS splitter at the central office (CO). The POTS splitter filters out the DSL signal and allows the POTS frequencies to pass through. Each central office POTS splitter card contains 12 filters to serve 12 local loops with DSL-based service and POTS. The POTS splitter card is a passive device and requires no power. NOTE: For the purposes of this document, both MVL and RADSL technology are referred to as DSL cards. POTS Splitter Chassis The POTS splitter chassis is shipped separately from the POTS splitter card(s). Two chassis are available: 1-slot card chassis which can be placed on a tabletop or installed in a rack. 6-slot chassis which must be installed in a commercial EIA-standard 19 or 23 rack or cabinet. POTS Splitter Cards Two POTS splitter cards are available. This Card... Interoperates with Hotwire DSLAM POTS Splitter 8510, 8540, and 8546 RADSL cards POTS Splitter 8310 MVL card A2-GN

2 Before You Begin Consider the following before installing the POTS splitter: Installation Site The location should be well-ventilated, clean, and free of environmental extremes. Allow clearance at the front of the POTS splitter chassis to provide access to the cables. Cabling Three Telco 50-conductor cables are used to connect to the three interfaces on each POTS splitter card. The location of the system hardware affects the length of the three cables. Cables and Hardware You Need For each POTS splitter card, obtain three Telco 50-conductor cables with 50-position amphenol-type connectors at the appropriate length based on cabling requirements in your environment. A Y-cable is available for the DSL connection. Refer to Cabling Overview, page 11, and Connector Pin Numbers, page 17.

To plan the bracket and chassis installation, determine: Width of the rack: 19 or 23. Chassis position in the rack: center mounted or front mounted. Center mounted is recommended for convenient access to cables. Whether the rack has mounting rails with threaded or non-threaded screw holes. If a 1-slot 8600 DSLAM chassis is being placed on a table top. If so, plan to install the rubber feet as shown on page 3. Discard rubber feet for any rack-mounted chassis. NOTE: In order to reduce the risk of accidental tip over, it is strongly recommended that the chassis be installed into the rack from the bottom up A2-GN

6 Installing the Brackets The brackets can be installed in the chassis in a center-mounted or front-mounted configuration. Mounting holes are provided in the chassis for either configuration. Install the appropriate 19 or 23 brackets on the 1-slot or 6-slot chassis. 1-Slot Chassis 19-Inch Rack 23-Inch Rack Slot Chassis Center Mount 23-Inch Rack Front Mount 19-Inch Rack Select one of the next two procedures for chassis installation in a rack A2-GN10-30

7 Installation into a Rack with Threaded Screw Holes Procedure After installing the appropriate brackets on the chassis: 1. Determine the preferred placement of the chassis in the rack. 2. Use the four Phillips-head mounting screws provided and a Phillips screwdriver to install the chassis. Front Rail Screw Tighten all four screws. To install the next chassis in the same manner, follow Steps 1 through 3. For a standard rack installation, chassis can be mounted directly on top of each other A2-GN

8 Installation into a Rack without Threaded Screw Holes Procedure After installing the appropriate brackets on the chassis: 1. Determine the preferred placement of the chassis in the rack. 2. Insert a speed nut onto each mounting rail hole selected and align the hole of the speed nut with the hole in the rail. Front Rail Speed Nut Screw Use a Phillips screwdriver to install the: 1-slot chassis in 19 or 23 rack, or a 6-slot chassis in a 19 rack. 6-slot chassis in a 23 rack. Install the top two screws loosely enough to allow the bracket s upper keyholes to drop under the screw heads during installation. 4. Line up the chassis-mounting bracket with the speed nut and start to rotate the speed nut screw into the chassis mounting bracket and the speed nut. 5. Loosely install the bottom screws first and then the top screws. Tighten each screw until the head is flush with the chassis and securely mounted in the rack. To install the next chassis in the same manner, follow Steps 1 through 5. For a standard rack installation, chassis can be mounted directly on top of each other A2-GN10-30

11 TM In the 6-slot chassis, each filler panel is attached to the chassis with two 1/4-turn fasteners. Remove a filler panel and replace with a POTS splitter card, as needed. Keep filler panels in all unused slots. CO POTS Splitter 6-Slot Chassis Filler Panel 1/4-Turn Fastener DSL Interface Loop Interface PSTN Interface 1/4-Turn Fastener Cabling Overview The interfaces to both the POTS splitter card and the DSLAM use 50-position amphenol-type connectors. Each DSL line uses one pair of copper wires. Each POTS splitter card uses 12 pairs of the 25 pairs on each 50-position connector. The 12 pairs for the POTS splitter card can be connected directly to the DSLAM using a straight-through cable or connected directly to the MDF. In order to directly connect 24 POTS splitter pairs, use a Y-cable to combine 12 pairs from two POTS splitter cards. The Y-cable Part Number is 8000-F A2-GN

12 TM TM A B POWER ALARMS A B Fan Major Minor Cabling Examples To connect 24 pairs from two POTS splitter cards to the DSLAM, use a Y-cable. The DSLAM connector feeds 24 DSL ports, comprised of six slots with four ports per DSL card slot. Interface connections: DSL Interface connects to the 8800 DSLAM using a Y-cable. The Y-cable enables 24 POTS splitters to serve 24 DSL lines on the DSLAM. LOOP Interface connects to the local loop via the main distribution frame. PSTN Interface connects to the local PSTN switch.
