Transfer Units

Installing the PFTU

This chapter describes how to install a QUA6 Power Failure Transfer Unit
(PFTU). This chapter contains the following procedure:
• Procedure 23: "Installing the PFTU" on page 185
You can connect PFTUs to the Main Chassis.
Note: The QUA6 PFTU operates with loop start and ground start CO
trunks. With ground start trunks, the associated telephone set must have
a ground start button.
If you require power failure backup as a fail safe for this system, use analog
trunks. A PFTU does not support digital trunks.
Refer to the equipment layout plan to determine where to locate the PFTU.
See "Chapter 4 — Creating an equipment layout plan and a card slot
assignment plan" on page 69.
Procedure 23
Installing the PFTU
1 Install the PFTU on the wall near the system cross-connect
terminal. Fasten the PFTU in position with four screws.
2 Install an NE-A25B-type 25-pair cable from connector J1 on the
faceplate of the PFTU to its assigned location at the
cross-connect terminal.
3 Label the pairs of the J1 cable on the cross-connect terminal
block as shown in Figure 56 on page 186.
