Federal Commu nications Com mission Radio Frequenc y Interference Statemen t:
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance
with the instruction manual, may cause harmful interference to radio frequencies. Operation of the is
equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
Changes or modifications to this unit not expressly app roved by the party responsible
for compliance could void the user’s authority to operate the equipment.

Introduction
IMUX-56/64 MODULE OVERVIEW
The IMUX-56/64 Module combines with other ATLAS components to provide a flexible disaster recovery system in the ATLAS Integrated Access System. The IMUX-56/64 Module, which occupies a single slot in the ATLAS
chassis, supports multiple, independent BONDING sessions with each session having the potential to use a different bandwidth. The IMUX-56/64
Module can use either 56Kbps or 64Kbps data lines (i.e., channels) for any
given BONDING session. The IMUX-56/6 4 Module can establish a BONDING session using as few as 2 or as many as 32 channels. Figure 1-1 shows
an example application of the IMUX-56/64 Module.

CONFIGURING AN ENDPOINT TO USE BONDING
How an endpoint is configured to use BONDING is unique to each type of
endpoint. Typically, it will be a reference to the number of DS0s, with men-
tion of BONDING in the help line. See the ATLAS 800 or 800
for more information on endpoint configuration. Information may also be

found in the help menus under the endpoint’s Dial plan Interface configuration.
For example, to configure an Nx endpoint for BONDING, set Max DS0s and
Min DS0s to something other than 1 under the Nx Dial Plan interface configuration (see Figure 1-2).
FUNCTIONAL DESCRIPTION
The IMUX-56/64 Module installs into any available slot in the ATLAS chassis. The status of the module itself can be viewed from the ATLAS front pan-
el. 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 IMUX-56/64 Module can be configured and application
software can be downloaded using the terminal menu.
Features
• Compliant with TIA/EIA-619 Standard (BONDING)
- Up to (32) 128Kbps BONDING sessions per module
- Up to (8) 512Kbps BONDING sessions per module
- Up to (2) 2.048Mbps BONDING sessions per module
• Event-driven dial-backup of frame relay or T1 circuits
• Support for 56K or 64K circuits
• Video Conferencing
• Software upgrades via FLASH download

PHYSICAL DESCRIPTION
The IMUX-56/64 Module has no external interfaces. Both the network and
DTE interfaces are provided on other ATLAS components. Information is
passed to and from the IMUX-56/64 Module via ATLAS’ internal bussing
scheme. Figure 1-3 illustrates the IMUX-56/64 Module card as seen from the
rear panel.

UNPACK AND INSPECT
Carefully inspect the IMUX-56/64 Module for shipping damages. If damage
is suspected, file a claim immediately with the carrier and then contact
ADTRAN Technical Support. If possible, keep the original shipping
container for use in returning the IMUX-56/64 Module for repair or for
verification of shipping damage.
