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.”
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
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
