4. Run Cable for System
4.1 Run Cables to Base Station Locations
The Base Station locations should be designated on the building floor plans provided to
the installer. Base Stations can be mounted easily on raised or 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.

One additional pair is required for Data.
Attenuation must not exceed 6.8 dB/1,000 feet @ 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
2,200 cable feet.
Install an extra 25 feet of wire at the Base Station to allow for possible
relocation.
