AT&T feature module 2 Power Failure Telephones, Different line modules, Outside calls

Power Failure Telephones

DESCRIPTION	In case of a power failure, a basic Touch-Tone or rotary telephone connected
	to a Power Failure Telephone jack in a control unit module has access to
	another line on the same module. (See Figure 2-26 to identify the PFT jack on
	different line modules.)
	When there is a power failure, all of the system except for power failure
	telephones, shuts off. If you have plugged a Power Failure Telephone
	into the PFT jack, the basic telephone automatically goes on when a power
	outage occurs. You can use the power failure telephone to place and receive
	outside calls.

CONSIDERATIONS

HOW TO USE

You cannot use a MERLIN II system voice terminal as a power failure telephone.

Plug the basic telephone into the power failure telephone jack on a control unit module. When there is a power failure, the power failure telephone connects to the first line on the module.
