ASYNC-232 MODULE OVERVIEW

The Async-232 Module combines with other ATLAS components to provide solu-
tions for a variety of wide area networking applications. Providing sixteen asyn-
chronous EIA-232 DTE ports, the Async-232 Module serves as the interface to
terminal servers and other DTE equipment. Each port of the Async-232 Module
can be configured to operate at any standard asynchronous rate up to 115.2 Kbps.
For remote access applications, ATLAS receives incoming analog or ISDN-based
signals from remote users, concentrated onto T1 or primary rate ISDN circuits.
These calls are processed and directed to the Async-232 Module via ATLAS' inter-
nal bussing system. As with all ATLAS components, configuration can be accom-
plished through a variety of mechanisms, including Telnet or VT-100 emulation.
SNMP management is supported for alarm and event reporting.

Functional Description

The Async-232 Module installs into any available option slot in the ATLAS chas-
sis. The ATLAS front panel displays the status of the module itself, as well as the
circuits to which it interfaces. In addition, the terminal menu gives further status
information, allows you to configure the Async-232 Module, and downloads
application software.
