47Digital Family Features
CTI (Computer Telephone Integration) applications
CTI applications, including Telephone Application
Programming Interface (TAPI), Telephone Services
Application Programming Interface (TSAPI), and the
proprietary interface TelradLINK, enable integration
of your DIGITAL systems and your personal computer
(see Section 7, DIGITAL KEY BX, DIGITAL 400 and
DIGITAL 1000 Computer Telephony Integration,
above.)
Day and night service
For day and night modes, various call handling
parameters for features (such as incoming ring routing
and Class Of Service assignment) may be programmed.
Day or night service mode is normally activated from
the attendant position.
Dial-By-Name (Automated Attendant DBN)*
See ImaGEN System Features in Section 5, ImaGEN
Voice Mail and Automated Attendant Features, above.
DID analysis
The DIGITAL systems Direct Inward Dialing (DID)
analysis system allows the handling of DID numbers,
received from the public exchange or the private
network, which contain more than four digits. DID
analysis also allows the processing of incoming DID
calls directed to specific trunk groups, where supported
by the public exchange.
Digital stations
The DIGITAL KEY BX, DIGITAL 400, and
DIGITAL 1000 systems supports all seven models of
Telrad Avanti family of digital telephone sets.
Direct In Lines (DIL)
Incoming calls on lines in the DIGITAL systems can
be programmed to terminate directly at an extension,
without being transferred from an attendant position.
Direct Inward Dialing (DID)
Since the DIGITAL systems have the ability to translate
incoming dialed digits, they support Direct Inward
Dialing from a Central Office. This enables outside
callers to dial directly to a particular extension within
the system, without the intervention of an attendant.
With the DIGITAL KEY BX system, you can store
200 number translations, with the DIGITAL 400
system, 400 numbers, and with the DIGITAL 1000
system 1500 numbers.
Direct Inward System Access (DISA)
An outside caller may dial into the system, access
system features and, after dialing a security password,
may even dial out of the system on the lines of the
DIGITAL system. A DID number can be routed to
DISA. To prevent unauthorized calls, DISA may be
deactivated during night service.
Direct Outward Dialing (DOD)
Outside calls, including long-distance and international
calls, can be placed from any extension, depending on
system programming, without the intervention of an
attendant.
Directory assistance*
See ImaGEN Incoming Caller Features in Section 8,
ImaGEN Voice Mail and Automated Attendant Features,
above.
Door Unit interface
An attendant and up to four designated stations can be
alerted to a person at the front door by an audio warning,
an indication on the station's display, and a programmed
station DOOR UNIT button. They may then converse
with the person, and release the door lock. The door
unit has a distinctive ring so that it can be easily
distinguished. Door units can be ring routed to different
locations in day and night mode.
