Run Cable for System
Run Cables to Base Station Locations
The Base Station locations should be designated on the building floor
plans provided to the Polycom field service engineer. 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 and/or repositioning.
Wire specifications
The customer’s wire contractor is responsible for adhering to all
local codes for wiring.
Polycom recommends UL-listed wire that conforms to the following
specifications for AWG, distance, and number of power pairs
required for this installation.
Power

Max Cable Feet
22 AWG
Max Cable Feet

One additional pair is required for data.
Attenuation must not exceed 6.8 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.
