Commercial power failure

Commercial power failure
If commercial power fails, the system’s battery backup keeps your console
operating for a short time. When this short time expires, the power failure transfer
automatically activates, and the console does not function. When power returns,
consoles return to normal operation. On the 302D, you must press the activate
button.
When power fails, all active calls and all calls on hold are lost. Also, a power
failure affects the following features that require corrective action:
■ Attendant Control of Trunk Group Access — Reestablish control of
desired outside lines.
■ Call Forwarding All Calls — Reactive Call Forwarding All Calls for
desired extension numbers.
■ Controlled Restrictions — Reestablish control of desired phones or groups
of phones.
■ Night Service — Reactivate Night Service as desired.
