Cable rerouting for Option 21–81 CE/PE, IPE/IPE-E modules

In a standard configuration, the Meridian MAX IPE/IPE-E module can be

placed in any peripheral slot on the Option 21–81 CE/PE or IPE modules.

This is possible when the slots are fully cabled to accommodate 24 tip and

ring pairs per slot. If your system is running a software release prior to

Meridian 1 X11 Release 18, you need to reroute cables inside the CE/PE or

IPE module.

In the standard backplane configuration of the NT8D11 CE/PE and

NT8D37 IPE modules, using a software release prior to Meridian 1 X11

Release 18, some slots on the backplane are fully cabled to accommodate

24 tip and ring pairs (3 cable connectors). Most of the backplane slots,

however, accommodate 16 pairs (2 cable connectors). By adding and

reconfiguring cable ends in the backplane slots, 24 pairs can be connected

to each backplane slot. Once the rerouting process is done, the CE/PE or

IPE cabinet can support the Meridian MAX IPE/IPE-E module.

Note: When backplane slots are reconfigured for expanded cabling,

the labeling for NT8D11 CE/PE and NT8D37 IPE modules must be

changed at the MDF to reflect the change in the backplane slots.

Cables are designated by the letter of the I/O panel (A, B, C, and so forth)

where the 50-pin cable connector is attached. Each cable has three 20-pin

connectors (16 positions are used) designated 1, 2, or 3, which attach to the

backplane. Using the designations described, the backplane ends of the first

cable are referred to as A-1, A-2, and A-3.

The location of the cable connectors on the backplane are designated by the

slot number (L0 through L9 for NT8D11, L0 through L15 for NT8D37)

and the shroud row (1, 2, 3). Using these designations, the slot positions in

the first slot are referred to as L0-1, L0-2, and L0-3.

Cable rerouting for NT8D11 CE/PE module

In the standard seven-cable configuration for the backplane in the NT8D11

CE/PE module, cables D, G, and L are not used. Those cables are used in

the 10-cable fully expanded configuration.

Cabling for the first four PE slots can be expanded using one NT8D81AA

cable/filter assembly. Cabling for all of the PE slots can be expanded using

three NT8D81AA cable/filter assemblies.
