Specifications

Direct Station Call Hold (Station Park)
This feature allows a station user to park a call at a
specific station where it 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 Pick-Up -
Directed and Call Park.
Direct Station Selection (DSS)
Programmable

Distinctive Ringing
Refer to the discussion titled Ringing.
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-not-disturb 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.
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.
Dual Console Support
Refer to the discussion titled Console Support.
Dual Intercom
Refer to the discussion titled Intercom.
Dynamic Line Buttons
Through class of service programming, the
programmer can arrange certain idle line buttons 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 operations can be
performed. Station class of service programming
allows certain buttons to be programmed as dynamic
line buttons
End-To-End Signalling
End-To-End Signalling On Intercom
After an intercom call has been established with an
ATI-D port, the system can continue to send dialing
signals (DTMF tones) through the intercom path. This
feature can be performed from every station in the
system, and is used by peripherals such as 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.
Exclusive Hold
Refer to the discussion titled Hold.
Exclusive Hold System-Wide
Enable/Disable
Refer to the discussion titled Hold.
Executive/Attendant Override
This feature allows the user of a station, upon ’
encountering a busy signal at another station, to dial a
code that will override the busy signal of a call, sound
a warning tone, and allow access to the existing
conversation. This feature is enabled through station
class of service programming.
External Paging Interface
Refer to the discussion titled Paging.
Feature Inhibit
A large array of individual features can be disabled
system-wide to provide a basic telephone system. A
basic telephone system is useful for installation
environments where a large proportion of the stations
are accessible to unauthorized users thus subject to
tampering or for environments where station users
must be limited as to the variety of features allowed to
them. Features are disabled by system class of
service. Once disabled, they can enabled by turning
on all features at once using the system default
programming.
