Digital-Port (DP) Board Emulation
In R3.1 and earlier releases, this term referred to both the port emulation and to the integration
method. In R3.2 and later, it refers to the port emulation only; the integration method can be either
control link (CL) or display set (DS).
Digital-Port (DP) Mode
The type of switch-link integration for which the DEFINITY AUDIX System, up through release 3.1,
is connected to the switch via digital port board emulation. The type of port board that the DEFIN-
ITY AUDIX emulates within the switch (TN754.)
Digital Signal Processor (DSP)
Programmed RAM chips on the Multifunction board that provide signaling, power-level control,
speech coding, and data processing.
Display Set (DS) Integration
A new term that replaces the term digital port integration for R3.2 and later. It refers to the use of
the display and other messages sent from the switch to the port board for providing voice mail
integration with the switch. Integration with the switch is achieved via display set messages. The
messages carry information such as calling party identification and message waiting indicator
status and control.
Disconnect Signaling Detection
Signaling from the CO to the PBX which indicates that the far end caller has hung up.
Dual Language Greetings
When the Call Answer Language Choice is in effect, the subscriber can record personalized
