GENERAL
Station wiring has a significant role in today’s customers’ information systems.
Technological innovations have enabled both voice and data transmission to be provided
through communications system wiring and have simplified wiring by significantly reducing
the number of cable pairs required by terminals with enhanced feature options.
This guide provides planning, ordering, and installation guidelines for a system Uniform
Wiring Plan (Figures 1-2 and 1-3) using Z100-, 110-type, or 66-type hardware.
The system switch ports for data and voice terminals require three pairs of wire per circuit.
Voice terminal adjuncts require an additional pair for remote powering. To provide
maximum flexibility for voice terminal changes, rearrangements, and powering, all data and
voice terminal information outlets are wired with 4-pair cable. With proper administration,
this will allow any terminal to be located at any information outlet.
