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