578 Linebacker (TM)

Automatic Operation:

               The 578 Porta Systems Linebacker™ Power Fail Transfer Unit automatically activates the instant of a power outage or system alarm. Dial tone is maintained to eight pre-designated lines and calls in progress remain uninterrupted—even after service is restored and the circuits are returned to PBX control - a feature not always available in other such units.

Quick Installation:

               The 66-type configuration mounts easily on a standard 89B bracket or backboard. The unit is equipped with two RJ21 connectors for quick connection to Central Office cables and stations. A 66-type clip field is also provided if cross-connection is required.
