Peripheral Equipment Power Supply 
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. 
Configuration guidelines
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 
Ringing Generator AC 
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.
Configuration guidelines
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
