Introduction
This chapter describes how to install a QUA6 Power Failure Transfer Unit
(PFTU). This chapter contains the following procedure:
•
Procedure 42 "Installing the PFTU" (page 230)
For the Cabinet system, you can connect PFTUs to the expansion cabinets
as well as to the main cabinet. Only one PFTU is supported per cabinet.
For the Chassis system, you can connect PFTUs to the chassis.
The QUA6 PFTU operates with loop-start and ground-start CO trunks.
Note: With ground-start trunks, the associated telephone set must be
equipped with a ground-start button.
If you require power failure backup as a fail safe for the system, use analog
trunks. A PFTU does not support digital trunks.
PFTU installation
Refer to the equipment layout plan to determine where to locate the PFTU.
