Emergency Transfer
Emergency Transfer provides service to and from the local telephone company
central office (CO) during a power failure or when service is impaired. Emergency
Transfer is also called Power Failure Transfer; the terms are synonymous.
Detailed description
Emergency Transfer allows analog telephones (500- or 2500-type) to access the
local CO and to answer incoming calls during a power failure.
Each DEFINITY ECS cabinet supports Emergency Transfer panels via the AUX
connectors on the rear panel. The transfer is initiated when:
■ a transfer panel or associated cabinet loses power.
■ someone manually activates the Emergency Transfer switch on the
associated maintenance circuit pack
■ the software determines that service for that cabinet is severely impaired
You cannot activate any other system features during a complete system power
failure.
