OCTAL BRI S/T MODULE OVERVIEW
FUNCTIONAL DESCRIPTION
61200343L1-1
Introduction
The Octal BRI S/T Module is a member of the ATLAS family of integrated
access products, providing eight Basic Rate ISDN (BRI) S/T interfaces, each
capable of operating in NT mode.
The Octal BRI S/T Module combines with the ATLAS 800 Series base unit
and other ATLAS modules to support requirements calling for multiple BRI
circuits. As many Octal BRI S/T Modules can be installed in a system as can
be physically accommodated in the ATLAS 800 chassis. Figure 1-1 shows a
sample application of the Octal BRI S/T Module.
T1/PRI Module
When combined with the ATLAS 800 Series base unit and, optionally, one or
more Quad T1/PRI Modules, the Octal BRI S/T Module can implement an
ISDN access switch, combining multiple BRI circuits into one or more Pri-
mary Rate ISDN (PRI) circuits.
The Octal BRI S/T Module installs in any available option slot in the ATLAS
800 Series chassis. You can view the status of the module itself, as well as the
circuits to which it interfaces, from the ATLAS front panel. Additional status
information is available via the terminal menus, accessible through either a
VT-100 terminal connected to the ATLAS 800 Series control port, or via a Tel-
net session established through the base unit's Ethernet port. Use the termi-
nal menu to configure the Octal BRI S/T Module and to download
application software.
