Digital Telephone System
of an external paging amplifier and the installer can arrange the wiring so that the relay
closures energize the paging amplifier while it is receiving the ringing tone. Use system
class of service programming to choose either the paging port. or station port 17 for the
ringing port relay control. Also use system class of service to determine the type of
ringing sent to the paging port. Use station class of service programming to determines
the type of ringing that the system sends to station port 17.
Programmers can arrange for the system to send ringing tones for particular lines
through the PA port. They can choose between intercom tone and DTMF signaling tone
for the PA port ringing. They should choose the intercom tone if they desire a soft tone
and the DTMF tone if they desire a loud tone.
Common Audible Ringer Interface
Connections are available at the common equipment that provides "dry-contact" relay
closures whenever an incoming line rings. These contact closures track the ringing
pattern and can be used to control an external signaling device.
Delayed Ringing
Ringing assignments are programmable. A station can be programmed to provide
delayed ringing on some lines while providing immediate ringing on other lines.
Delayed ringing is assigned to certain lines at each station through station class of service
programming. When a programmer assigns delayed ringing to a station for certain lines,
he or she can also assign the time length of the delay.
Distinctive Ringing
The ringing cadence of an incoming call is the same as the ringing cadence of the
TELCO, PBX, or CENTREX system. The ringing cadence of an intercom call presents
two tone bursts sounded every four seconds.
Flexible Ringing Assignments
Ringing assignments are programmable on a per station/per line basis. Ringing can be
controlled for every line that has an appearance at each station. Delayed ringing is
assigned to certain lines at each station through station class of service programming.
Flexible Ringing Assignments Of PA Port
The PA port can be programmed for flexible ringing assignments and zone pages. Any
desired lines can be programmed for direct ring, delay ring, or night transfer (of ringing)
at this port. Paging can be to programmed zone or to all-call. A speaker can be connected
to the PA port to sound the ringing that is generated by the system and sent to this port
