T1/E1/ISDN PRI NIM Card Ports

The T1/E1/ISDN PRI NIM comes equipped with either 1, 2 or 4 Ethernet (WAN) ports that support fractional T1/E1 transmission in full-channel, fractional or unchannelized format with 8- pin modular RJ-48C connectors and include a built-in DSU/CSU, as shown in Figure A-12.

Cables required for these ports must be 100-ohm, straight-through, twisted-pair for T1 lines and a 120-ohm version for E1 lines. Refer to Figure A-13for pinout assignments.

Note: m version for E1 lines. Refer to Figure 13 for pinout assignments. If you are using the TI/EI/ ISDN PRI NIM in Singapore or Australia, the cables required for these ports must not employ individual shields for each pair.
