2.11 Using A Line Port As An
External Paging Interface
You can use class of service programming to program a line port to be an AUXILIARY port. As
an AUXILIARY port, a user can use it to couple a telephone to an external paging device that
you have wired to the line port. He or she does this from any station with that line presence by
pressing the proper line button to select the AUXILIARY port. The user can dial DTMF tones or
dial pulses through the AUXILIARY port as needed. The paging enable relay closure feature
discussed previously is not available for use with this installation.
• Connect the audio input of a customer-supplied external paging amplifier to the tip and ring
leads of the AUXILIARY port.
• You can install a DTMF tone select, zone-paging amplifier if you wish. If you do install
this type of amplifier, the user must dial the zone-select code after he or she presses the
AUXILIARY port line select button.
