SpectraLink 6100 MCU: Installation and Operation: SpectraLink 6000 System

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 exits the building, consult the telephone system
manual, the National Electrical Code (NEC), and local codes for
instructions on providing lightning and other over-current protection.
When cabling an external Base Station or a Base Station with
wiring that exits the building, protect all Base Station wiring with the
Quick Clip Fuse (Illinois Tool Works, Linx Division, SCP-2X2)
before bridging with other Base Station power leads.
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.
