Power Failure Transfer
Description
Power Failure Transfer ensures that a customer has access to the Central Office network during a power
outage. The CO/PBX tip and ring are automatically transferred to the time and ring of a pre-selected
single line Single Line Telephone. The single line telephone can function in the system during normal
operation or be used during a power failure.
Conditions
The single line telephones that are installed must provide dialing signal accepted by the
outside exchange (dial Pulse or dual-Tone Multifrequency).
Only single line telephones cross-connected at the MDF can be used for this feature.
Single line telephones and outside lines connected during power failure are fixed
one-to-one.
Single line telephones must be equipped with a ground start button for use with Ground
Start Trunks.
System features cannot be activated from single line telephone when Power Failure
Transfer is in operation.
When power is restored to the system, Power Failure Transfer is cancelled. Calls in
progress on Power Failure Transfer lines are disconnected.
Refer to the Electra Elite IPK II System Hardware Manual for the MDF Pin Numbers and
