DECvoice system
An integrated hardware and software product that provides a computer
with a voice application platform.
Device
The general name for any entity connected to a system that can receive,
store, or transmit data.
Diagnostic program
A program that detects and identifies abnormal system hardware
operation. The MicroVAX Diagnostic Monitor software used to test a
system contains several diagnostic programs.
DTC04 module
The DECvoice module board that provides computers with voice
capability. The module is a Q-bus option that installs in the MicroVAX II
Q-bus backplane.
DTMF key
The telephone keys that produce the tone signals that a Touch-Tone phone
creates.
Encoding algorithm
The voice encoding algorithm that DECvoice uses to store voice data.
DECvoice supports three voice encoding algorithms: full bandwidth 64
Kbits/s -law, full bandwidth 64 Kbits/s A-law, and 16 Kbits/s subband
compressed encoding.
Event
A response to an RTL routine that DECvoice communicates to the
application. Applications can use the VOX$GET_EVENT routine to
retrieve events from DECvoice.
Formatted data
Data laid out in a particular pattern to conform to a predetermined
structure. The structure is dictated by the system software.
Hardware
The physical components—mechanical and electrical—that make up the
DECvoice system. (Compare Software.)
