Overview:
The BP-5 Power Failure Transfer Unit is designed to connect two-wire Central Office (CO)ground start or loop start trunk lines to selected station telephones in the event of a power failure or telecommunications system malfunction. When used with ground start trunks, the BP-5 includes automatic loop start to ground start conversion circuitry to provide the signaling required to draw CO dial tone when a station telephone is brought off-hook. This eliminates the need to add ground start push buttons to the station telephones. In the normal, non-transfer mode of operation, the BP-5connectsthe CO trunk lines to trunk ports on the associated PBX system; PBX extension ports are connected to the station telephones.
