2.4 Fault Recovery/Diagnostics
2.4.1 Power Failure Transfer
Description
When the power supply to the PBX fails, specific SLTs and/or ISDN terminal devices are automatically
connected to specific trunks (
Power Failure Connections
). The PBX will switch from normal operation to the
Power Failure Connections, and all existing conversations will be disconnected.
Only the trunks handled by Power Failure Connections can be used during a power failure.
Conditions
•
Only trunk calls can be made during a power failure. All other features do not work.
•
DC Power Source
If the DC power is available from backup batteries, even if the AC power fails, the PBX will remain fully
operational.
•
The analogue trunk cards and extension cards, as well as the number of PFT ports (ports which can be
used for Power Failure Connections) are as follows:
Trunk Cards:
LCOT16 (4 PFT ports), LCOT8 (2 PFT ports), LCOT4 (2 PFT ports), and CLCOT8 (2 PFT
ports)
Extension Cards:
MCSLC24 (2 PFT ports) and MCSLC16 (2 PFT ports)
Only connect one extension card to each trunk card.
Note
Through system programming, it is possible to allow trunk calls that are established during a power
failure to be maintained even when the power returns and the connection is switched back to the normal
configuration from the Power Failure Connection. However, if no special programming is performed,
the connection will be dropped when power returns.
•
The BRI8 (one PFT port) and BRI4 (one PFT port) cards can also be used for Power Failure Connections.
For details about Power Failure Connections, refer to the Installation Manual.
