AC 

The Peripheral Equipment Power Supply AC is used to provide power to all

peripheral equipment modules in 

 systems. It converts 

 V ac to

 V, 

 V, 

 V, 

 V, and -48   dc voltages used to power peripheral

equipment logic cards and to supply “talk battery” to lines and trunks. This
power supply is located in the far left hand card slot labeled “PE Pwr Sup.”

Configuration guidelines  One Peripheral Equipment Power Supply AC is

used in each of the following AC modules:

 Intelligent Peripheral Equipment Module 

 Peripheral Equipment Module 

Common/Peripheral Equipment Power Supply AC 
The Common/Peripheral Equipment Power Supply AC converts

 V ac to 

 V, 

 V, 

 V, 

 V, 

 V, -150 V dc, and

86 V 

 Hz ringing voltages used to power peripheral and common

equipment, supply talk battery, and light Message Waiting lamps on 

sets. It is located in the left of the Module in the slot 

 

 

sup. 

One Common/Peripheral Equipment Power

Supply AC is used in each of the following AC modules:

 Common/Peripheral Equipment Module 

 or 

 Remote Peripheral Equipment Module 

The AC Ringing Generator AC operates from a nominal 

 V ac input

and provides selectable AC ringing voltage outputs superimposed on 

 V dc.

The frequency and voltage options are 70 V ac at 

 Hz, 80 V ac at 

Hz, and 86 V ac at 

It also supplies -150 V dc message waiting lamp

 set applications. The Ringing Generator mounts in the PE modules

to the right of the Peripheral Equipment Power Supply.

One Ringing Generator AC is used in each of the

following, when these AC modules support 

 or 

 analog sets:

 Intelligent Peripheral Equipment Module 

 Peripheral Equipment Module
