2.9 Power Failure Connections
2.9.1 Power Failure Connections
When the power supply to the PBX fails, power failure transfer will switch from the current connection
to the Power Failure Connections.
Power Failure Connections connect a specific extension and an outside (CO) line in the event of
power failure as follows:
Outside (CO) line 1—extension (T, R) jack 01
Outside (CO) line 4—extension (T, R) jack 09
Outside (CO) line 7—extension (T, R) jack 17
Notes
• In the event of a power failure, system memory is protected by a factory-provided lithium
battery. No system data will be lost, except for the Camp-on, Saved Number Redial, Last
Number Redial and Call Park data.
• The current connection automatically switches to the Power Failure Connection when the
power supply stops.
• Proprietary telephones (PTs) cannot be used during a power failure. Therefore, we
recommend connecting single line telephones (SLTs) in parallel with PTs to extension jacks
01, 09, and 17.
