Power Failure Transfer

The Power Failure Transfer relays are located on the COT Blades (CN3). 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. Each COT Blade supports two power failure transfer connections.
During a power failure condition, CO Ports 1 and 2 on the COT Blade are used
for Power Failure Transfer relays 1 and 2 consecutively.
