Connecting the cables
WARNING
Always use caution when installing or modifying telephone lines.
Avoid installing telephone wiring during a lightning storm. Never
touch uninsulated telephone wiring unless the line has been
disconnected at the network interface.
For the Cabinet system:
Each cabinet requires up to ten 25-pair cables. Each cabinet requires
an additional terminal block at the cross-connect terminal for the
termination of the 9-pin conductor auxiliary cable.
All cables are connected at the bottom of the cabinet and are routed
through the openings in the lower part of the cabinet.
For the Chassis system:
Each chassis requires up to five 25-pair cables. The chassis requires
an additional terminal block at the cross-connect terminal to terminate
the 9-pin conductor auxiliary cable.
Connect all cables at the back of the chassis.
Note: Use caution when using NE-A25B cables with the NTAK02
card. These cables are not wired out to station equipment or trunk
circuits. Do not use the NE-A25B cable with the NTAK10, NTBK50,
or NTAK79 circuit cards.
For 1.5 Mbit and 2.0 Mbit DTI/PRI-related wiring and cable information, refer
