External Paging Interface
The system provides a special transformer-isolated
paging port that you can use to couple the system to a
customer-supplied external paging amplifier. This
external paging port does not provide a talk-back path
nor will it recognize DTMF dial tones.
You can use the relay closure dry-contact points that
the system makes available at the ringing port terminal
for controlling the external paging amplifier during a
paging operation. These contacts close and stay
closed during the time that a paging operation is active
to provide a constant enable signal path for the paging
amplifier.
IMl66-107
NOTE: This paging enable constant closure function
overrides the ring pattern closure provided
when ringing is sent to the paging port.

the previous paragraph titled -on Au&&
0 Connect the audio input of a customer-supplied
external paging amplifier to the paging port as
shown below in Figure 3-10.
0 If the paging amplifier requires an enable signal,
connect the enable leads to the station 17 audible
terminals as shown in Figure 3-10.
