FUNCTIONAL DESCRIPTION
The VCOM Module installs into any available slot in the ATLAS 800
chassis. You can view the module status from the ATLAS front panel (see
Chapter 4 of the ATLAS 800
menu to provide additional status information, configure the module, and
download application software. Access the terminal menu either via a
VT-100 terminal connected to the ATLAS Base Unit's control port or via a
Telnet session established through the Base Unit's Ethernet port.
VOICE COMPRESSION RESOURCES
• The VCOM Module ordering options provide 8, 16, 24, or 32 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) generation and detection.
• The VCOM Module enables and disables individual voice compression
resources.
