Portable systems
The following sections describe the portable systems that are compatible with the Business
Communications Manager system, and the hardware components that are required.
Companion system components
The Companion system allows portable access from a fixed line. The system consists of the
following hardware components:
• Companion base station — transmits and receives signals between the Business
Communications Manager hardware and portable handsets. You install the base stations on
walls or ceilings. Each base station provides radio coverage for a maximum of 32 cells.
• C3050 portable handset — The C3050 CT2 Plus portable handset is available in Canada
only. The Etiquette C3050 portable handset is available in the USA only. You can assign the
C3050 portable handset a separate telephone number or the same telephone number as a
desktop telephone. The C3050 supports basic features such as call forward, call transfer,
conferencing and visual message waiting indication. The C3060 handset is also supported.
• Remote power interconnect (RPI) Unit — The RPI provides remote power for base station
support. There are two types of RPIs: RPI-8 that supports a maximum of eight base stations
and RPI-16 that supports a maximum of 16 base stations.
DECT system components
The DECT system allows the user to access calls and call features while away from their stationary
telephone. The following components combine with the DECT media bay module to provide this
service:
• Radio base station — provides the radio link between the Business Communications
Manager, through the DECT module, to the portable handsets.
• Portable handsets — communicate through radio base stations connected to the DECT
module.
DECT system installation and configuration information is contained in the Business
Communications Manager DECT Installation and Maintenance Guide.
Note: Companion systems installed in the United States require a keycode to activate the
base stations. Refer to the Companion Installation and Configuration Guide.
Note:
The DECT cordless handset can be configured to act as a separate set, either providing a
point for target line calls, or with full call and receive capability, although some of the
features are not available.
The handset can also be twinned with desk sets to provide mobile coverage of one or more
stationary sets.
