Power Failure Transfer

The Power Failure Transfer relay is located in the KSU. When selecting a
Single Line Telephone for power failure transfer, make sure it matches the CO
line dialing type (10 pps, 20 pps, or DTMF) where it is connected. A Single
Line Telephone with a ground button must be used with Ground Start Trunks.
