Introduction

Power fail transfer occurs when the main power to the CS 1000E system is cut off. When a power interruption occurs, the Power Fail Transfer Unit (PFTU) connects predetermined analog (500/2500-type) telephones directly to the Central Office trunks. A PFTU is capable of supporting a maximum of five or eight telephones (depending on the PFTU type).

A PFTU can be connected to the AUX connector on a Media Gateway.

IMPORTANT!

A PFTU does not support Digital trunks. Use Analog trunks if power failure backup is required.
