Testing the Power Failure Transfer Jacks
To test a power failure transfer (PFT) jack for proper operation, the outside line
numbers to the module's line/trunk jacks must be assigned and the trunks
must be operational. A PFT telephone on a GS line must have a GS button
attached to the telephone. See Figure 7–1.
