Power Down Mode
What’s this?
During power failure, it is desirable to have trunk lines available directly on few stations. This is known as Power
Down Mode. When mains power returns, normal operation resumes. Change over from normal to power down
operation and back is automatic.
During power down mode, by default, Trunk 1 gets connected to station 21, Trunk 2 gets connected to station
22, whereas Trunk 3 gets connected to station 23. At the time of Power failure/Power return ongoing calls gets
disconnected.
During power failure condition, calls can be made from these stations. Also the incoming calls lands on
respective stations. This way, your link with the outside world is retained even during dark-outs.
