COMPANION 200 Installation and Maintanence Guide
The Base Station is the communication link between the portables
and the COMPANION 200 system. Each Base Station contains two
radios and connects to a TCM port at the Controller either directly
or through a Base Station Module. Each Base Station can handle two
portable calls simultaneously.
A module mounted alongside the Controller and connected to it
through an Expansion Cartridge. Each Base Station Module
provides support for 16 additional Base Stations.
A method of twinning a portable and a desk (wired) telephone. The
wired telephone and the portable are assigned the same host switch
telephone number when bridge-tapping is used. An incoming call
rings on both telephones and can be answered on either. Only one
call can be active on the line assigned to the host switch telephone
number. For example, when a call is active on the portable, a second
call cannot be made on the twinned wired telephone.

The area covered by one or more radios in close proximity. One or
more cells make up the coverage area. Cell sizes vary with layout

Base Station) specified for radio coverage. During site planning, this
value is used to locate the outer edge of the coverage area for each
cell (see RSSI reading).
The location of the radios or the external antennas serving a cell.
This is the point of reference for determining the cell boundary.
