Description Of System Feats
to the DISD assist station if one is programmed;
otherwise, the line is dropped. If the assist station is
busy (call will camp-on at the assist station) or
lf
the
assist station does not answer before the transfer recall
timeout period, the system will return the caller to DISD
dial tone. If extension number dialing is not completed
within the dial time limit this time, the line is dropped.
It is recommended that a music source be connected
to the system to provide a reassurance to the caller
during a camp-on situation when the DISD feature is
being used.
DIRECT STATION CALL
HOLD (STATION PARK)
This feature allows a station user to park a call at a
specific station where
lt
will be held without ringing. A
feature code plus a station extension number can be
dialed over the intercom line to park the call or a
programmable button can be programmed to provide
a “directed hold” to a specific station. The parked call
is picked up by directed station by dialing a feature
code. It can be picked up at any station through the
use of the call pickup feature. No class of service is
required. Also refer to the discussions titled: Call
Pickup
-
Directed and Call Park.
DIRECT STATION SELECTION (DSS)
PROGRAMMABLE
Refer to the discussion titled: ProgrammableDSSlBLF.
DISTINCTIVE RINGING
The ringing cadence of an incoming call is the same as
the ringing cadence of
theTELC0,
PBX, or CENTREX
system. The ringing cadence of an intercom call
presents two tone bursts sounded every four seconds.
DO NOT
DISTURB
Any station can be set to a do-not-disturb mode (DND)
using the designated DND programmable button and
associated indicator (indicator will light when DND is
active). While in the DND mode, the station will not ring
on any incoming call nor will it accept an intercom call.
A party making an intercom call to a station set in the
do-notdisturb mode hears a fast busy tone. The
feature cannot be overridden by the calling party
unless the override feature is enabled. The DND
feature is used with the departmental calling feature to
provide a station wrap-up mode and a station off-duty
mode.
Refer to the discussions tftled: Do Not Disturb
Override, Executive/AttendantOvertide, and
Departmental Calling Distribution Report.
DO NOT DISTURB INHIBIT
The system can be programmed to inhibit any station
from entering the DND mode. System class of service
programming is used to program this feature.
DO NOT DISTURB OVERRIDE
Stations can be provided with DND override capability
which will allow them to call a station that is set in the
DND mode. The Executive/Attendant Override feature
must also be active for DND override feature to
function. Station class of service programming is used
to assign this feature. Also refer to the discussions
titled: Do Not Disturb and Executive/Attendant
Override.
DUAL INTERCOM
This feature provides for two separate intercom lines at
the same station. One intercom line is fixed and is
accessed with the ITCM button. The other intercom
line is programmable and is accessed by a
programmable button selected for that purpose by
class of service programming. Calls are handled on
the intercom lines in much the same manner as
outside calls are handled using the line buttons.
Special considerations are as follows:
Distant party hang-up causes intercom link to drop.
Intercom call to station already busy on intercom
rings in subdued fashion and flashes indicator
associated with other intercom button.
With both intercom lines busy, a third intercom call
resufts in a secure off-hook voice announce (if
enabled) at busy station.
Pressing a DSS button while on an active intercom
call will drop the distant party unless the automatic.
hold feature is enabled for the intercom line
through class of service programming. The hold
button can be used, however, to place an intercom
call on hold before selecting the other intercom
line for use.
Any action taken on the intercom by a station
being observed via the service observing feature
will cause the observing station to return to an idle
state.
The station class of service button mapping procedure
assigns a programmable button to serve as the second
intercom button.
DYNAMIC LINE
BUlTONS
Through class of service programming, certain idle line
buttons can be arranged to serve as dynamic line
buttons. This feature allows the system to temporarily
assign a line to a station that normally does not have
the line assigned to
it,
and have that line appear on a
dynamic line button. While the call is appearing on the
dynamic line button (LED on), any normal call handling
