Descriotion Of Svstem Features
IMl66-107
Pulse/Tone Switchable
The programmer can program the system on a per line
basis using the line class of service programming to
allow the stations to switch from pulse to DTMF type
dialing as needed. Alternately, she or he can program
the system to only allow tone dialing.
Redialing
Automatic Redial (Of Busy
Number Or Unanswered Call)
A user can automatically redial a busy number or
unanswered call by activating this feature. Once the
user activates automatic redial, the station will select
the line, automatically dial the number, and wait for a
response. It will do this once a minute for
approximately 10 minutes unless the user deactivates
the feature by pressing that button or another button or
by lifting the handset. The feature cycle is timed and
does not have busy detection circuitry. Because of
this, if the user is operating handsfree when the called
party answers, she or he must lift the handset to
prevent the caller from being cut off by the timing
cycle. The automatic redial button is a designated
programmable button position and the user must
program its location to make it active.
Automatic Pause Insertion
When the system stores a dialed number for later
redial, it automatically stores a pause whenever the
user waits between digits for at least two seconds.
The system inserts the automatic pause in the stored
number sequence at the point where the manual
pause in dialing occurred. The length of the automatic
pause is programmable.
Last Number Redial
Each station is provided with a last number redial
feature. This feature will save 32 digits of the last
outside number dialed. A newly dialed number will
always automatically replace a previously dialed
number. Upon command, the system will choose a
line and redial the saved number. The system will first
choose the prime line if assigned and idle. If it is busy
or unavailable, the system will choose any line
assigned to idle line preference. If they are
unavailable, the system will chose the last line used at
the station. If it is busy, no further choice is made. No
class of service is required.
Saved Number Redial
This feature enables a button action to save the first
16 digits of the last number manually dialed from the
keypad. The saved number can be redialed at a later
time, The saved number is permanently available for
later use until it is replaced with a new number.
When the caller identification feature is active, this
saved number redial feature will save the identified
number for redial.
Response Messaging

Remote Programming And Administration

Ringing
Auxiliary Ringer Interface
The auxiliary ringer interface provides “dry-contact”
relay closures which track the ringing pattern
whenever the system sends ringing to a
programmable destination. Programmers can
program relay control to be activated when the system
sends ringing to station port 17 or to the paging port.
When programmed for station port 17 ringing, an
installer often uses an external device to provide loud
ringing. When programmed for paging port ringing, an
installer often installs an external paging amplifier to
sound the rings. The system supplies ringing tones to
the paging port along with the relay closures. It can
send the ringing tones to the input 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.
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
signalling 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.
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.
