acoustical ceiling tiles, or on the wall. Avoid locating Base Stations in high or hard-
to-reach places, as this will hinder maintenance, testing, or repositioning.
Wire Specifications
The customer’s wire contractor is responsible for adhering to all local
codes for wiring.
SpectraLink recommends UL-listed wire that conforms to the following
specifications for AWG, distance, and number of power pairs required for this
installation.

2 N/A 6,000 4,800
3 N/A N/A 6,000
One additional pair is also required for Data.
For wire runs of less than 3,500 feet, attenuation must not exceed 6.8
dB/1,000 feet at 772KHz.
For wire runs between 3,500 and 6,000 feet, attenuation must not exceed
4.5 dB/1,000 feet at 772KHz.
Wire that is already installed (spare house cable) can be used when it is available.
House cable will usually run from the MDF in the telephone equipment room to
intermediate distribution frames (IDFs) spread throughout the facility. Install new
wire from the closest IDF to the Base Station. Be sure no bridge taps, multiples, or
“Y” connections are created or present.
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
6,000 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, refer to section 6.3
Install Outdoor Base
Stations
.
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.
