EXTERNALPAGING AND PAGE RELAYS
Using External Paging
The Auxiliary PCB has one External Paging audio output
and one associated control relay. You connect the audio out-
put to the audio input on customer-provided paging systems.
In some paging systems, you can use the control relay to
automatically turn the amplifier on and off. The control
relay is normally opened and closes whenever a user calls
the External Paging zone.

DOOR BOX

Using the Door Box
Each Auxiliary PCB supports two Door Boxes. In addition,
you can connect each circuitÕs control relay to an electric door
strike. This allows an extension user to remotely activate  the
door strike while talking to a visitor at the Door Box. The
control relays are normally open.
Installing a Door Box

1. Locate an available 2-pin DDK connector in an auxiliary
(C) block.
2. For the DDK connector chosen, cross-connect the associated
wire pair from the C block to...

MUSIC SOURCES
4-12
Music on Hold
Music on Hold (MOH) provides music to callers on Hold.
The systemÕs default setting provides an internal (synthe-
sized) MOH music source, or a customer-provided music
source connected to the Auxiliary PCB can be used instead.
There are two jumpers that determine whether or not the
system will play Music on Hold.  The first jumper is located
on the CPU and is labeled SW2.  This jumper should be set
to the ON position.  If it is not, it overrides the setting of the
SW1...

CALLER ID
4-14
Using the Caller ID Feature
Each Auxiliary PCB supports the use of Caller ID on the
three CO lines in the system.  Caller ID allows a display key-
set to show an incoming callerÕs telephone number and/or
name with the time and date on the phoneÕs display.  The
callerÕs information can be checked before answering an
incoming call.  The information received by the system
depends upon the capabilities of your local telco.
