Digital-Port (DP) Mode
The type of switch-link integration for which the DEFINITY AUDIX Sys-
tem, up through release 3.1, is connected to the switch via digital port 
board emulation. The type of port board that the DEFINITY AUDIX 
emulates within the switch (TN754.)
Digital-Port (DP) Board Emulation
In R3.1 and earlier releases, this term referred to both the port emula-
tion 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 Signal Processor (DSP)
Programmed RAM chips on the Multifunction board that provide signal-
ing, 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 mes-
sages. The messages carry information such as calling party identifica-
tion 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 greetings for each of the languages listed as 
the primary and secondary announcement sets. The subscriber 
instructs the caller to enter *1 to switch to the alternate language.
E
Errors
Problems detected by the system during automatic self-tests and 
recorded in an error log. Errors can produce an alarm (fault) if they 
exceed a threshold.
Events
Occurrences such as inline errors, maintenance procedure failures, 
alarms, errors, or transitions into or out of the 
AUDIX
 or 
OA&M
 states 
which are recorded in an events log.
F
Faceplate and Alarm Controller (FAC)
For release 3.2 and earlier versions, the circuitry on the Multifunction 
board that monitors activity of the DEFINITY AUDIX System.
