Do Not Disturb
Any station can be set to a do-not-disturb mode using
the SPKR button. While in this mode, the station will
not ring on any incoming call nor will it accept an inter-
com call. A party making an intercom call to a station
set in the do-not-disturb mode hears a fast busy tone.
The feature cannot be overridden by the calling party.
DSWBLF
Console (Optional)
The
DSS/BLF
Console is designed to be a companion
to any system station. It is useful with high call
volume systems which require a dedicated call trans-
fer location. The console provides a one-button direct
station selection (DSS) intercom and an associated
busy lamp field (BLF). It also provides one-button ac-
cess 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 sys-
tem 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;;dS;~alllng
After an outside call has been established, the system
can continue to send dialing signals (DTMF tones)
through the
telw
network and have them received at
the distant end for inward call completion (bank by
phone, etc.). This conventional, off-hook dialing fea-
ture can be performed from every station in the sys-
tem. 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 con-
dition also links the held call to the timed hold recall
timeout feature. After timeout, audible and visual
sig-
nalling will occur and the exclusive hold condition will
revert to a normal line hold condition. System or ad-
ministration programming can enable this feature.
External Paging Interface
A station port or line port can be programmed to inter-
face 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 program-
ming can be used to program a line port as an exter-
nal paging port.
Extended Dual Tone Multiple
frequency
(DTMF)
Tones
The model XE telephone system can access answer-
ing machines, banking computers, voice mail equip-
ment, etc. that require DTMF tones that are longer
than the standard one with a 50 ms. on and off time. A
shift to a longer tone of preprogrammed length is auto-
mat
i
cally made 10 seconds after a line is selected or
10 seconds after the last digit is dialed. A user can
shit
from one tone length to the other by pressing the
HOLD button and then selecting the line again. While
the off-time of a DTMF tone is maintained at 50 ms,
the class of service programmer can increase the
on-
time 80 ms. so that he or she can program even
longer DTMF tones. Normally a short DTMF tone
gives satafactory results but
lf
a longer one is needed,
the programmer should choose the one
with
the
shortest tone duration that is necessary. 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/nor?-Square
Qs-
tern.
Flexible Ringing Assignments
Ringing assignments are programmable on a per sta-
tion/per line basis.
Ringing can be controlled for
everyg
line that has an appearance at each station. Direct, or
immediate, ringing can be programmed for some as-
signed lines and delayed ringing programmed for
others. Direct or delayed ringing is programmed
through system or administration programming.
