2.5 Power Failure Transfer
The Power Failure Transfer relays are located on the COIU 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
COIU blade supports two power failure transfer connections. During a power
failure condition, CO Ports 1 and 2 on the COIU Blade are used for Power Failure
Transfer relays 1 and 2 consecutively.
Table 3-1 Power Failure Transfer
Connections is a relay diagram. The relay is shown with the power ON.
NOTE

Power Failure and FAX Branch Connection do not function
simultaneously on the same port. Use Program 14-02-21 (Fax Branch
