At each cell center, one radio (the Common Signaling Channel,
CSC, radio) is dedicated to locate and track portable movements.
The other radios of that cell center (traffic radios) are used to
establish voice connections with the portables.
Characteristics of CSC radios:
• The CSC radio will always be busy.
• You cannot measure the RSSI of a CSC radio.
• When the voice traffic in a given cell is high, the CSC radio may
be used as a traffic radio.
• The CSC radios are allocated randomly at startup.
• If a CSC radio is disconnected, the system chooses another radio
at that cell center to be the CSC radio.
The COMPANION Deployment Tool (CDT) is used to map the
radio coverage of a system. It is composed of a transceiver with
stand and a portable. The portable used with the CDT is a standard
COMPANION portable. The transceiver resembles a Base Station,
but is a special purpose device and will not operate when connected
to a Controller.
The Companion Diagnostic Software (CDS) provides access to real-
time and historical radio performance on the COMPANION 200
system. CDS runs on a personal computer (located either on site or
in a remote location), and connects to the COMPANION 200
through a Remote Access Device (RAD).
Configuration programming is used by the installer to customize a
COMPANION 200 system as determined by the user or the host
system requirements, and to establish the basic operation of lines
and Base Stations in a Companion system. Configuration allows you
to change parameters such as radio data, line access, line data, etc.
The central hardware component in the Companion system. The
Controller has 32 built-in TCM ports for the Base Stations, the
Administration Terminal, and the Remote Access Device (if used).
It can also support up to eight access lines with the addition of Line
Cartridges. Its capacity can be increased by connecting Base Station
