T1/E1/ISDN PRI NIM Card Ports
The T1/E1/ISDN PRI NIM, as shown in
Figure A-12
, 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.
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-13
for pinout assignments.
