T7406 cordless systems
The T7406 cordless system consists of a base station that connects to three ports on a Business
Communications Manager digital station module, providing a radio interface for three cordless
handsets. The cordless handsets register to the base station, which transfers the call over the
telephone lines connected to the system. The handsets are configured to emulate the T7316/M7310
telephone features. This system is most suited to small to medium office environments set up in an
open fashion.
T7406 cordless telephones use the DNs for the ports on the station module that the base station is
connected to. They are digital sets and use M7310/T7316 as an operational model.
The T7406 Cordless Telephone Installation Guide provides:
• deployment parameters
• a description of the handset features
• instructions for installing the base station
• instructions on how to correctly charge the handset battery
• general operational directions, including describing special operational features of the handset
Moving Telephones
You can move an Business Communications Manager digital telephone to a new location within
the system without losing its programmed settings if the telephone has been enabled with
Set relocation. When you enable Set relocation (automatic telephone relocation), the internal
numbers, autodial settings, and personal speed dial codes remain with the telephone when you
disconnect the telephone.
If you connect a different telephone to the jack before you reconnect the moved telephone, the new
telephone takes the programmed settings. The Business Communications Manager system can no
longer identify the old telephone.
After you plug a moved set into a new jack, the Business Communications Manager system can
take 45 seconds to identify the telephone. Programming relocation takes three minutes to
complete. Wait for this to occur before you change any settings for the telephone in the system.
For IP telephones to retain DN-specific features, the Keep DN Alive setting for the telephone
programming must be set to Yes.
If
Warning: If you disconnect a relocated telephone before the relocation programming is
complete, the telephone can lose the programmed settings.
Note: Automatic telephone relocation is disabled by default.
