OPX SUPPORT
The system supports the operation of the optional off
premises extension (OPX) unit. System or
administration programming arranges a station port for
OPX operation.
A device (such as a model 2500 telephone set or
compatible device) that is connected through an OPX
unit to a station port can access both intercom and
outside lines. The system default provides intercom
line access when the device goes off-hook. With
either prime line alone or prime line and idle line
preference enabled through programming, the device
connected through the OPX unit will seize an outside
line when it goes off-hook. After going off-hook, the
user can get the intercom line by pressing theTAP
button. If no digits are dialed after going off-hook, the
outside line is dropped when the TAP button is
pressed. If digits are dialed after going off-hook, the
outside line is placed on hold when the TAP button is
pressed.
ORIGINATING DENIED
The ability to originate calls on certain lines can be
denied at individual stations through system
programming. The originating denied feature is
programmed on a per station/per line basis.
Originating denied does not prevent a user from
answering a ringing line, retrieving a held call or
receiving a transferred call. Call origination on a line is
denied at a particular station by the system or
administration programming.
PBX/CENTREX/CENTRAL OFFICE
COMPATIBLE
System features and programmable buttons support
the requirements of most PBXs, Central Offices, and
CENTREX systems. Numbers, #’s, S‘s, programmable
pauses, and flash signals can be made a part of every
stored number for access to host system feature
codes.
PERSONALIZED RINGING TONE
This programmable feature enables stations to ring in
a distinctive manner with one of four different tones.
The ringing tones are combinations of four different
frequencies and two different warble rates. Personal
ringing tones can be assigned with system or
administration programming.
POWER FAILURE TRANSFER
A power failure line connection is available for
installing an industry-standard telephone such as a
Comdial model 2500-xx. The installed power-fail
telephone is automatically connected directly across
line 1 by the system whenever there is an AC power
failure. Normal origination and reception of calls
through the power-fail telephone is possible during an
AC power failure. The power-fail telephone is
automatically disconnected as soon as power is
restored.
POWER ON, VISUAL INDICATION
The common equipment has a red LED which
monitors the status of the system, and provides an
“AC power-on” indication.
PRIME LINE AUTOMATIC
If a station is programmed for prime line automatic, the
designated outside line or intercom line will be
automatically selected when the handset is taken off
hook. Prime line pick up may be pre-empted by
preselecting another line before lifting the handset. If
the prime line is ringing, it is automatically answered
by lifting the handset. Assign a prime line to a station
through system or administration programming.
PRIVACY RELEASE
A line can be made non-private at a particular station
while remaining private at all other stations. This
arrangement allows other stations with that line
appearance to join that particular station whenever it is
on the privacy-released line. A line is specified as
private or non-private at a particular station with
system or administration programming. Also see the
discussions titled, Add-on Conference and Automatic
Privacy.
PROGRAMMABLE BUTTONS
All multiline keysets are equipped with a minimum of
twelve programmable buttons which can be
programmed a line pick-up, auto dial, station speed
dial, and DSS action. Refer to the discussions titled,
Auto Dial, Programmable DSS, And Station Speed
Dial. System or administration programming is used to
assign functions to programmable buttons.
PROGRAMMABLE DSS/BLF
(DIRECT STATION SELECTION/BUSY LAMP
FIELD)
A multiline station user can store true, one-button,
direct station selection (DSS) at any programmable
button location to create a DSS button. When this
button is pressed, any active outside call is
automatically placed on hold and an intercom call is
automatically made to that previously stored station
number. The visual indicators of the stations
programmed at the button locations form a busy lamp
field (BLF). The BLF conveys station status to the
user. An auto dial number can also be programmed
as a secondary function at every DSS/BLF memory
location. Also refer to the discussions titled, Tone Or
Voice Signalling (Intercom) and Auto Dial.
