Issue, April 998. GENERAL.0 The DLx System provides a circuit access interface for network elements in digital transmission systems. The DLx System concentrates digital system signals in a centralized area providing the flexibility to be distributed in interconnect or cross-connect arrangements as desired by the customer. It also provides technicians the capability to perform circuit maintenance and service provisioning functions at a centralized location.. DESCRIPTION.0 The DLx System provides improved cable management and easy access for circuit monitoring and reconfiguration. The primary components of the system are: Chassis mounting and cable management bracket 6-circuit chassis Coax modules Equipment racks/cabinets A. Chassis Mounting and Cable Management Bracket.0 The chassis mounting and cable management bracket, as shown in Figure, has one 6- circuit chassis attached. The combination of two mounting brackets and two chassis is referred to as a chassis group, providing 3 module positions. Cable management tie bars are provided on the brackets for routing and securing network element cables, separating them from the U-link/looping cords and cross-connect jumpers. This provides efficient management of the coaxial cables and easy access to the coax connectors. Optional cross-connect jumper troughs are available (ordered separately) for cross-connect systems. The trough includes a cable guide plate to aid in the management of cross-connect jumpers between chassis.

Issue, April 998 B. 6-Circuit Chassis.03 Each chassis is designed to house 6 individual circuit modules. Refer to Figure. The chassis provides a common platform such that any module type can be mounted into the same chassis providing flexibility for configuring the system to meet the needs of a variety of network applications. Cable management rings are provided at the top and bottom of the chassis, and a ground post is provided at the rear of the chassis for connecting to a local office ground. C. Coax Modules.04 Each coax module provides two.6/5.6 connectors for terminating cables. Modules with BT 43 and BNC connectors are also available. The modules include a designation card on the front for circuit identification and are fastened to the chassis by a thumb screw on the front of the module. A monitor is also available for some modules providing a permanent monitor port at the front for easy access. The monitor port allows non-intrusive access by providing a signal.5 db below the output signal. Different coax modules are available for a wide range of applications as shown in Table and Figure.

Issue, April 998 TO GROUND POST TO RACK GROUND 0699-A Figure 0. Chassis Mountings C. Installing the Chassis to Rack Ground 3.05 Chassis and rack ground wire requirements must conform to local regulations. Each chassis is designed to be grounded to the rack. The rack to central exchange ground must be locally provided. A chassis ground post is located on the rear of each chassis. ADC recommends using 0.643 mm ( AWG) or equivalent wire from the chassis ground post to the rack ground. 3.06 Prepare the chassis ground to rack ground wire as follows:. Prepare an appropriately sized ground wire that will reach from each chassis ground post to the rack ground. Allow enough length to route the wires along the mounting bracket up to the top of each chassis.. Feed the ground wire along the mounting brackets. Refer to Figure 0. The chassis ground wires can be routed both to the left, both to the right or separately to the left and right depending on the location of the rack ground. Secure chassis ground wires to tie lances provided along chassis mounting bracket. 3. Connect the wire at the rack end only at this time, leave the chassis end until the chassis is prepared and ready for mounting. D. Installing Chassis 3.07 For interconnect applications, chassis connecting plates are attached to the bottom of one chassis and the top of the chassis below it. See Figure. For cross-connect applications crossconnect jumper troughs with cable guide plates are available and must be ordered separately. Refer to Figure. When the cross-connect jumper troughs are used, the chassis connecting plates provided are not used. Page 3 998, ADC Telecommunications, Inc.
Issue, April 998 3.08 Prepare and mount the chassis as follows:. Ensure the chassis mounting screws are backed out far enough for the chassis to hang on them. Refer to Figure 0.. Align keyholes at rear of chassis over mounting screws, place chassis on screws and tighten screws. Note: Always install chassis furthest from cable entrance first. Refer to Figures 8 and 9. 3. Repeat Steps through for remaining chassis. 4. Skip step 4, for cross-connect applications. For interconnect applications attach the chassis connecting plate between adjacent chassis as shown in Figure A or B. Only attach plates to connect adjacent chassis. Do not install plate on last chassis group. Note: It may be necessary to loosen chassis mounting screws to align mounting holes. 5. Connect the chassis end of the rack ground to the ground post located on the rear of the chassis. See Figure. 6. Return to all chassis mounting bracket screws and tighten securely.

The DLx System is designed to route network equipment cables to the left side, as viewed from the front, of each chassis and U-Link/looping cords or cross-connect jumpers connected to the right side. For basic interconnect applications, the right-hand side is also used for routing network equipment cables. Page 8 998, ADC Telecommunications, Inc.
Issue, April 998 3.3 The routing of network element cables to each chassis group depends upon system configuration, interconnect or cross-connect, and rack floor mounting, raised floor or concrete floor. See Figure 6. When network element cables enter the rack from the bottom (raised floor), the cables are routed to chassis group (top) first and then work down. When the network element cables enter the rack from above, the network element cables are routed to chassis group (bottom) and then work up. Route cables to chassis using the recommended pattern for each chassis. See Figures 7 and 8.

Cross-Connect and Interconnect with U-Link/Looping Cord 3.5 For these applications the network element and cables always connect to the left side of the module. The cross-connect jumpers and U-Link/looping cord always connect to the right side of the module. See Figures 0 and. Page 998, ADC Telecommunications, Inc.
Issue, April 998 3.6 Recommended cable connections on each module type for typical arrangements are shown in Figures 9, 0 and. Each module must be at the out stop position when making network element connections. Then tie the cable bundles off at the succeeding chassis group mounting bracket, refer to Figure 7 or 8. This will provide slack for sliding the coax module in and out of the chassis. CABLES CABLES CABLES U-LK/LOOPG CORD X- X- 034-A 03-A Figure 9. Basic Interconnect without Monitor Figure 0.

Issue, April 998 4. OPERATION 4.0 Operation of the DLx system consists of establishing circuits with cross-connect jumpers, looping cords or interconnection of network element cables at the coax module. In addition to establishing normal circuit connections, maintenance test setups can be performed at the coax module. A. Installing Cross-Connect Jumpers 4.0 Cross-Connect jumpers always connect to the right side of the coax module. The connections between origination and destination chassis must follow basic rules to maintain good cable management. All jumpers leaving a chassis or chassis group must follow a path that only changes directions at a cable ring. See Figure.
