Business Communications Manager Companion Configuration Guide
Chapter 1
Installing the Companion system
This section describes the process for installing a Companion wireless system.
This book assumes the following has been completed:
• A site survey has been completed and you have determined the exact locations of the base
stations around your site.
You have determined how many handsets you want.
To determine this, you need to know whether your system has a DS30 channel 2/6 or 3/5 split.
• The Companion requires a DSM8 module for every 32 handsets. You can assign a maximum
of 32 Companion handsets per DSM because the Companion system can use both B channels.
You can install a maximum of two DSM8s or one DSM32 for Companion handsets, per
system, providing your system is configured with a DS30 channel 2/6 split. Refer to the
Business Communications Manager Installation and Maintenance Guide for detailed hardware
configuration.
This section includes the following information:
• “Companion components” on page 13
• “Hardware installation process map” on page 14
• “Companion components” on page 13

• “Installing external antennas and lightning surge protection” on page 30
Companion components
Your Companion portable telephone allows you to leave your desk without missing telephone
calls. The telephones can access most Business Communications Manager business features such
as call forward, call transfer, voice conference, and voice messaging using feature codes.
Business Communications Manager Companion has four main components:
Software - Companion software manages the telephone traffic between Companion base stations
and portable telephones. Base stations connect to the Business Communications Manager in the
same way that Business Communications Manager telephones do. You register the Companion
portable telephones on the system. They do not require any ports on the system. You can connect a
maximum of 60 portable telephones and a maximum of 32 base stations (32 cells) to the system.
Note: If you choose a 3/5 channel split for your system, you cannot assign a module to
channel 7. This limits you to a maximum of 16 base stations, which can support a
maximum of 30 handsets.
