1002 Matrix ETERNITY NE System Manual
Power Fail Transfer
When the power supply to SARVAM UCS fails, SLT 1 is automatically connected to the CO1. The PBX switches
from normal functioning mode to the Power Failure Connection mode. Only CO1 trunk can be used during a power
failure. Outgoing calls can be made from SLT1 extension as well as incoming calls on the CO1 trunk can land on
this extension. When power is resumed and normal functioning of the system is restored, calls on the Power Failure
Connection remains unaffected until they are terminated.
