Connecting CT1/PRI CSU Modules to the Network

To connect a CT1/PRI CSU module to the network, use a straight-through RJ-48C-to-RJ-48C cable to connect the RJ-48C port to an RJ-48C jack (see Figure 10). These ports are color-coded tan.

Channelized E1/ISDN PRI Balanced (120-Ohm) Network Modules

This section provides information about the following network modules for Cisco modular routers:

•1-port channelized E1/ISDN PRI balanced (120-ohm) network module (NM-1CE1B or CPANM-1CE1B) (see Figure 11). This module is also referred to as the 1-portCE1/PRI-B network module.

•2-port channelized E1/ISDN PRI balanced (120-ohm) network module (NM-2CE1B or CPANM-2CE1B) (see Figure 12). This module is also referred to as the 2-portCE1/PRI-B network module.
