Determine the amount of wire needed to connect the Base Station to

the MCU by scaling from a floor plan or a sketch, pacing, measuring,

or estimating. Remember to include enough wire to reach the ceiling.

The wire length between the MCU and each Base Station may not
exceed 2,200 cable feet.
Install an extra 25 feet of wire at the Base Station to allow for
possible relocation.

Pull Cable

Pull the cable from the MCU location (usually in the telephone

equipment room) to the Base Station locations designated on the floor

plans.

If the cabling between the MCU and the telephone system or to the
Base Station leaves the building, consult the telephone system
manual, the National Electric Code (NEC), and local codes for
instructions on providing lightning and other over-current protection.

Run all cable before attaching the RJ-45 connectors to the Base

Stations. Label both the demarcation block end and the Base Station

end of each wire with the Base Station number using a wire tie marker

or other form of marker.

Remove bridge taps, multiples, or “Y” connections to the Base
Station wires; these will cause data transmission errors.

The area above some suspended ceilings is used as an
environmental air plenum. The NEC requires that wire installed in
plenums be rated for plenum installation.
