Central Location Ed-1E434, Group 460 Or 462 Tms Fiber Link(S) (Phases 1 And 2) - AT&T System 85 Installation And Test

Central Location ED -1E434, Group 460 or 462 TMS Fiber Link(s) (Phases 1 and 2)
Install the TMS fiber link(s) for the central location from the TMS carrier(s) to the central
LCIT. Figures 52 and 53 show the connections for an unduplicated and duplicated system.
WARNING: The cable must be loosely supported to prevent damage. The
fiber-optic cable has a minimum bend radius of 1.5 inches.
Use the CSD to determine the connector pins that are used on TMS carriers(s) for the TMS
fiber link to each remote module. If CSDs are unavailable, Table AB can be used to
determine this information for an unduplicated system. Tables AC and AD can be used to
determine this information for a duplicated system. Look up the module number of each
remote module in the appropriate table, and use the corresponding TMS carrier and pin
numbers to connect from the TMS backplane to the LCIT as shown in Figures 52 and 53.
The number of a remote module is determined by the module that is in the system.
Install the TMS fiber link as follows:
1. Connect transmitter (Z982C) and receiver (Z982D) paddleboards to the appropriate
connectors on the backplane of the TMS carrier(s). The transmitter paddleboard must
be mounted first.
2. Connect transmitter paddleboard Z982C to Fiberl/Blue and the receiver paddleboard
Z982D to Fiber2/White of the ED-1E434, Group 460 or 462 lightguide cable.
3. Route the cable out of the auxiliary cabinet to the central LCIT along the outside of the
overhead ducts using locally provided hardware. Figure 47 illustrates the routing of
lightguide cables.
4. Connect the appropriate attenuator to the central LOT (Figure 46) in the correct
position as determined by your CSD.
5. Connect the fiber-optic cables to the appropriate attenuator as shown in Figures 52 and
53.
