Adtran 1200186L1 OCTAL BRI/U Interface

OCTAL BRI/U Interface

The ADTRAN® ATLAS™ includes an advanced
access architecture for switching dial-up calls
to specific ports or DS0s. The Octal Basic
Rate ISDN (BRI) module contains eight ISDN
U-Interfaces and combines with other ATLAS
components to implement an ISDN access
switch. The Octal BRI module can connect to
the ISDN network (NT mode), or it can
emulate the ISDN network to other ISDN
access devices (LT mode) that support the
U-Interface, such as terminal adapters and
network termination units.
As a component in an ATLAS access
switching application, the Octal BRI module
can consolidate multiple Basic Rate ISDN (BRI)
connections onto T1/PRI access lines. The
module also supports BRI-to-BRI and BRI-to-
PRI switching. In addition, ATLAS converts
between ISDN D-Channel (PRI or BRI) and
T1 robbed bit signaling, allowing non-ISDN
equipment to access a more efficient PRI or BRI facility. Moreover, the module’s call
filtering feature allows you to program on
a per-user basis, the call types that will be
answered and originated.
Single B-Channel ISDN calls can be
directed to synchronous V.35 ports operating
at 56 kbps or 64 kbps. For asynchronous
applications, ISDN calls can be routed to
EIA-232 ports on the Async-232 module.
The Octal BRI module can be configured
through a variety of mechanisms, including
Telnet or VT100 emulation. SNMP management
is supported for alarm and event reporting.
The Octal BRI module includes an
extensive array of diagnostic tools to assist
in identifying and correcting network problems
including a built-in Self-Test utility, local
and remote loopback testing for B1, B2, and
2B+D, and performance monitoring to ensure
the quality of the ISDN line.
