Emergency transfer capability is provided by an 808A Emergency Transfer Panel (or equivalent)
mounted next to the trunk/auxiliary field. See
Also refer to Table 21, Emergency Transfer and Auxiliary Power,

Use analog telephones for emergency transfer. The 500-and 2500-type telephones can also be used as
normal extensions. Emergency transfer capability may be provided on analog CO and Wide Area
Telecommunications Service (WATS) trunks.
The transfer panel provides emergency trunk bypass or power-fail transfer for up to 5 incoming CO trunk
loops to 5 selected station sets. The 808A equipment's Ringer Equivalency Number (REN) is 1.0 Amp.
At the MDF, the unit is controlled by a connection to a yellow terminal row/connecting block in the
trunk/auxiliary field. The unit is controlled by -48 VDC from the EM TRANS RELAY PWR terminals.

housing has ears for screw-mounting and cutouts for snap-mounting the unit in an 89-type

meet standard environmental considerations such as temperature, humidity, and so forth.
