MODEM-16 MODULE OVERVIEW

The Modem-16 Module combines with other ATLAS components to implement a
high-capacity modem pool in the ATLAS Integrated Access System. The Modem-
16 Module, which occupies a single slot in the ATLAS chassis, supports sixteen
K56flex modem calls or sixteen ISDN connections. Using the ATLAS Async-232
Module provides remote users with dial-in access to external equipment through
EIA-232 ports. ATLAS provides support for up to 48 modem or ISDN users per
system. Figure 1-1 shows a sample application of the Modem-16 Module.

FUNCTIONAL DESCRIPTION

The Modem-16 Module installs into any available slot in the ATLAS 800 chassis.
The status of the module itself, as well as the circuits to which it interfaces, can be
viewed from the ATLAS front panel. Additional status information is available
via the terminal menu, accessible through either 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. The Modem-16 Module can be configured and applica-
tion software can be downloaded using the terminal menu.
