8-Pin Modular
Note: The cable that connects to this connector is provided in the NT7T87AA
T1 CSU Cable Kit. The cable is a straight through cables between the Carrier
Remote IPE 8-pin modular jack and the Telco demarcation point. If the carrier
links are just hardwired without using Telco network, pins 1 and 2 must be turned
over (swapped) with pins 5 and 4 respectively at one end of the cable.
