Connecting the cables

WARNING

Always use caution when installing or modifying telephone lines. Do not install telephone wiring during a lightning storm. Never touch uninsulated telephone wiring unless the line is disconnected at the network interface.

Each Option 11C Mini system chassis requires up to five 25-pair cables. The Main 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, and NTAK03 cards. These cables are not wired out to station equipment or trunk circuits. Do not use the NE-A25B cable with the NTBK45, NTAK10, NTBK50, or NTAK79 circuit cards.
