Nx56/64 IMUX
ATLAS 550 Resource Module
|
The ATLAS 550 IMUX 56/64 Module combines multiple ISDN B-channels using the
BONDing Mode 1 protocol to support high bandwidth ISDN applications such as dial
backup of frame relay or dedicated circuits. The inverse multiplexing (IMUX)
capacity of the module is 32 DSOs or ISDN B-channels (2.048 Mbps total), which
can be allocated according to the user's needs. For example, one bonding session
in an ATLAS 550 could be configured to bond eight B-channels as a dial backup
link to a remote 512 kbps device such as the ISU 512. Similarly, the total
bonding capacity of the module might be configured to implement two sessions at
512 kbps, one at 384 kbps, and five at 128 kbps. The table on reverse shows how
many sessions can be supported at typical BONDing rates.
The ATLAS 550 IMUX 56/64 Module has no external network or user interfaces
and is a plug-on board for all user modules and the resource host module.
Network traffic is passed to it though other ATLAS modules such as the Quad BRI
Module or the Dual T1/PRI module. Similarly, traffic is passed to the user
through modules such as the Dual Nx56/64 module. This partitioning allows the
IMUX 56/64 Module to serve as a resource for multiple user devices.
When combined with the ATLAS 550, the IMUX 56/64 module can offer high speed
dial backup around the network in frame relay applications. This same capability
can be applied to providing dial backup of failed dedicated circuits or other
network connections. Other applications that may call for the IMUX 56/64 Module
include image transfer and video conferencing.
The IMUX 56/64 Module is compatible with the ISDN Dial Backup options of
ADTRAN's ATLAS 800 Series, Express 5000 series products, and the IQ family of
frame monitoring CSU/DSUs. It is also compatible with ISDN Access products such
as ADTRAN's ISU 128 and ISU 512, as well as the ISDN dial backup options of the
TSU family of T1 access devices.

In addition to the specific configurations described in the above
table, it is possible to configure ATLAS for a combination of IMUX
speeds, e.g., three 512 kbps sessions and four 128 kbps sessions.
Multiple IMUX 56/64 Modules can be installed in an ATLAS system to
increase capacity.
