Companion base stations — Position the base stations around the coverage area to send and
receive calls between the portable telephones and Business Communications Manager. Base
stations use digital radio technology and support handoff and roaming within the coverage area.
The coverage area can be a maximum of 160,000 square meters (1,700,000 square feet) when
using the maximum number of base stations.
Companion wireless handsets — Business Communications Manager supports the following
wireless handsets: Companion 3020, Companion C3050 Etiquette, Companion C3050 CT2Plus,
and Companion C3060.
The portable telephones used with your Business Communications Manager system are small,
lightweight units with complete digital performance to provide clear voice quality. Companion
portable telephones feature a three-line, 16-character, alphanumeric display.
Administration and maintenance tools — Programming of the Companion system is easily and
quickly done through the Business Communications Manager Unified Manager. You can assign
portable telephones to the system, check base station parameters, and enable and disable
registration through programming.
Companion Diagnostics software allows you to run diagnostics on the wireless system. You run
the diagnostics using a personal computer located at the customer site or in a remote location.
