Building Wiring

Building (station) wiring (must be 24 AWG or heavier) from voice and data terminals to the equipment location should already be in place. System 25 wiring requires that 4-pair circuits be distributed from the equipment location to each station’s wall jack. The SIP hardware (Figures 2-2 through 2-6),designed specifically for this purpose, is furnished with each system. Except in extraordinary circumstances, this cross-connect hardware must be used.

In unusual circumstances where the 617A Panels are not used and some other cross-connect equipment that does not provide a modular jack interface to the port circuits is used, separate 4-pair circuits must be run for the voice and data terminal at the workstation.

All examples and instructions in this manual assume that a SIP is used.

The station wiring terminations in the equipment area should have been labeled to indicate the room location and jack number of the other end of the line. When SIP connections are made, the connection information should be entered on the Voice and Data Station Records Form (see Install Equipment Room Station Cabling in this part for details).
