Introduction
VOICE COMPRESSION MODULE OVERVIEW
The Voice Compression Module (VCOM Module) combines with other
ATLAS 550 components to implement a voice over frame relay (VoFR)
capability in the ATLAS 550 series of Integrated Access Systems. You can
order the VCOM Module with support for 4, 8, 16, 24, or 30 simultaneously
compressed calls.
FUNCTIONAL DESCRIPTION
The VCOM Module installs onto any option module that can be installed in
the ATLAS 550 chassis. You can view the module status from the ATLAS 550
front panel LEDs (also see Chapter 4 of the ATLAS 550 User Manual). You can
also use the terminal menus to provide additional status information,
configure the module, and download application software. Access the
terminal menus via either a VT-100 terminal connected to the ATLAS 550
Base Unit's control port or a Telnet session established through the Base
Unit's Ethernet port.
VOICE COMPRESSION RESOURCES
• The VCOM Module ordering options provide 4, 8, 16, 24, or 30 voice
compression resources.
• The VCOM Module provides automatic selection of CCITT Standard or
ADTRAN-proprietary voice compression algorithms based on endpoint
configuration.
• The VCOM Module supports FAX at 14400 bps.
• The VCOM Module includes dual-tone, multi-frequency (DTMF) gener-
ation and detection.
• The VCOM Module enables and disables individual voice compression
resources.
