IMI 66-064 System Description
2-4
DSS/BLF CONSOLE (OPTIONAL)
The DSS/BLF Console is designed to be a companion
to any system station. It is useful with high call
volumesystems which require a dedicated call transfer
location. The console provides a one-button direct
station selection (DSS) intercom and an associated
busy lamp field (BLF). It also provides one-button
access to system-wide, all-call paging. The console is
designed to be connected to any station port and
serve as a companion to the station connected to the
adjacent data-paired port. System or administration
programming is used to program a station port as a
DSS/BLF port.
END TO END SIGNALLING
ON INTERCOM
After an intercom call has been established, the
system can continue to send dialing signals (DTMF
tones) through the intercom path to station ports that
are programmed as OPX unit ports. This feature can
be performed from every station in the system, and is
used by peripherals such as an OPX unit and voice
mail equipment.
END TO END SIGNALLING
ON LINES
After an outside call has been established, the system
can continue to send dialing signals (DTMF tones)
through the telco network and have them received at
the distant end for inward call completion (bank by
phone, etc.). This conventional, off-hook dialing
feature can be performed from every station in the
system. No class of service programming is required.
EXCLUSIVE HOLD
Exclusive hold prohibits a held call from being
retrieved by any other station. The exclusive hold
condition also links the held call to the timed hold
recall timeout feature. After timeout, audible and
visual signalling will occur and the exclusive hold
condition will revert to a normal line hold condition.
System or administration programming can enable this
feature.
EXTERNAL PAGING INTERFACE
A station port or line port can be programmed to
interface with an external paging amplifier. The
paging amplifier can then be dial accessed through the
station port or directly accessed through the line port
from other stations in the system. DTMF tones can be
dialed through the interface to make a zone selection if
zone paging is provided by the external paging
amplifier. System or administration programming can
be employed to program a station port as an external
paging port. Only system class of service
programming can be used to program a line port as an
external paging port.
EXTENDED DUAL TONE MULTIPLE
FREQUENCY (DTMF) TONES
The model XE telephone system can access
answering machines, banking computers, voice mail
equipment, etc. that require DTMF tones which are
longer than the standard 80 msec. tone. A shift to a
longer tone of preprogrammed length is automatically
made 10 seconds after a line is selected or 10
seconds after the last digit is dialed. A user can shift
from one tone length to the other by pressing the
HOLD button and then reselecting the line. It is
recommended that the shortest duration possible be
chosen. DTMF generation is a system feature and if
several stations are using the extended DTMF feature
at the same time, a delay in the time between button
press and tone sound may be noticed.
FLEXIBLE LINE ASSIGNMENT
Refer to the discussion titled, Square/non-Square
System.
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.
Direct, or immediate, ringing can be programmed for
some assigned lines and delayed ringing programmed
for others. Direct or delayed ringing is programmed
through system or administration programming.
HANDSFREE ANSWER INHIBIT
The MUTE button on a multiline station can be used to
block all handsfree answerback response. This
arrangement will prevent a station user from
monitoring another station site using the monitoring
ability of the voice announce feature. When the
button is pressed, all handsfree answerback is
disabled thus inhibiting any off-site monitoring. The
speaker light will flash to indicate that this feature is
active. Also refer to the discussion titled, Mute.
HEADSET INTERFACE
A station port can be programmed to allow the
operation of special telephones which provide the user
with a headset option. Programming for this feature is
through either system or administration programming.
HEARING AID COMPATIBLE HANDSET
The station handset is compatible with
magnetically-coupled hearing aids.
IDLE LINE PREFERENCE
The system can be programmed on a per station basis
to enable idle line preference. When idle line
preference is enabled, taking the handset off-hook will
