GLOSSARY OF TERMS
The following is a list of terms and their definitions, as used in this manual.
ACIF2-A
Advanced Computer Interface Board second design, revision A. This board works
with the WinACIF Software program and is used as an interface between the host PC
and evaluation board via a serial interface.
GCI
General Circuit Interface. Allows for a common data highway that conveys the PCM
encoded voice data, device programming commands and data, and loop control and
status information.
Mini-PBX Software
Embedded software application that runs on the VP Demo board and provides real-
time operation of the evaluation boards and line modules to allow performance and
evaluation testing in a real-time operational environment.
MPI
Microprocessor Interface. Communicates with an external microprocessor over a
serial interface. It passes user control information to internal blocks of the QLSLAC
device and passes status information from the internal blocks to the user.
PCM
Pulse Code Modulation. The modulation scheme involving sampling digitization,
filtering and encoding of an audio waveform.
SLIC
Subscriber Line Interface Circuit. Provides telephone interface functions to the two-
wire telephone line. Supports BORSHT functions.
VP Demo Board
Voice Path Demo Board. The board is used with the VP-Script software.
VP-Script Software
Voice Path Script software. Windows based interactive program. Provides interactive
control of the QLSLAC devices registers, filters and operating commands. Supports
PCM mode only.
WinACIF
Windows
®
based Advanced Computer Interface software program that provides
interactive control of the QLSLAC device's registers, filters and operating commands.
Supports PCM and GCI modes.
WinSLAC2 Windows based software tool that aids in the calculation of coefficients for the
programmable filters of a SLAC device along with predicted performance of system
parameters.
