Introduction
In the event of a power failure or system error in HiPath 3800, analog trunks can be transferred
(ALUM) to designated analog telephones. These are:
1 analog trunk with a PFT1 (Power Failure Tranfer) board
●
4 analog trunks with a PFT4 board
●
When using an analog telephone for outgoing calls, you may need to adapt its signaling method
to match the signaling method of the connected trunk.
