• 7406 cordless digital handset: This handset communicates with the BCM through a station
module that supports three handsets. The station module connects to a digital trunk installed
on the system.

Call out to external systems using host system dialing
When you make external calls, or forward calls to external systems, such as private branch
exchanges (PBX system), you may need to insert one or more Host System dialing signals to
connect the call. These features are also known as end-to-end signaling. Signaling features either
send a special signal to the host system or allow you to program delays required by host systems in
external autodial or speed dial sequences.
Programming : Same as for 7316 digital phone. This telephone has six display keys.
Programming : Refer to the Companion Installation and Configuration Guide , which is
included on the documentation CD for previous versions of BCM software. The handsets

Programming : Refer to the DECT deployment documentation and the DECT Installation
and Configuration Guide on your documentation CD. The handsets also come with a user
