Chapter 1 Introduction
IMUX-56/64 MODULE OVERVIEW
The IMUX-56/64 Module combines with other ATLAS components to pro-
vide a flexible disaster recovery system in the ATLAS Integrated Access Sys-
tem. The IMUX-56/64 Module 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-56/64 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.
Figure 1-1. ATLAS Remote Access Application
CONFIGURING AN ENDPOINT TO USE BONDING
The manner in which 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 mention of BONDING in the help line. See the ATLAS 550 or 550
manuals 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 config-
uration (see Figure 1-2).

FUNCTIONAL DESCRIPTION
The IMUX-56/64 Module installs onto any option module that can be
installed into one of the four user slots of the ATLAS 550 chassis. You can
view the module status from the ATLAS 550 front panel LEDs (also see
Chapter 4 of the ATLAS 550 User Manual). You can also use the terminal
menus to provide additional status information, configure the module, and
download application software. Access the terminal menus via either a
VT-100 terminal connected to the ATLAS 550 Base Unit's control port or a
Telnet session established through the Base Unit's Ethernet port.
Features
• Compliant with TIA/EIA-619 Standard (BONDING)
- Up to (16) 128Kbps BONDING sessions per module
- Up to (4) 512Kbps BONDING sessions per module
- Up to (1) 2.048Mbps BONDING sessions per module
• Event-driven dial-backup of frame relay or T1 circuits
• Support for 56K or 64K circuits
• Video conferencing support
• Software upgrades via FLASH download

PHYSICAL DESCRIPTION
The IMUX-56/64 Module provides no external interfaces. OtherATLAS 550
components provide both the network and customer interfaces. An internal
bus exchanges information between the ATLAS 550 chassis and the IMUX-
56/64 Module.

UNPACK AND INSPECT
Carefully inspect the IMUX-56/64 Module for shipping damages. If you
suspect damage, file a claim immediately with the carrier and then contact
ADTRAN Technical Support at the number provided in the back of this
manual. If possible, keep the original shipping container for returning the
IMUX-56/64 Module for repair or for verification of shipping damage.
CONTENTS OF ADTRAN SHIPMENT
The ADTRAN shipment includes the following items:
•IMUX-56/64Module
•IMUX-56/64 Module User Manual
(Insert into main ATLAS 550 User Manual.)
INSTALLING THE IMUX-56/64 MODULE
The IMUX-56/64 module must be attached to an ATLAS 550 option module
before the IMUX-56/64 module may be installed into the ATLAS 550 unit.
The IMUX-56/64 module can be attached to any type of ATLAS 550 option
module and the resulting assembly can then be installed into any option
module slot of the ATLAS 550 chassis. Only an ATLAS 550 option module
can be used to carry the IMUX-56/64 module. In particular, the IMUX-56/
64 module cannot be attached to any network module or inserted into any
network module slot of the ATLAS 550 chassis.
To install the IMUX-56/64 module onto an ATLAS 550 option module and
then into the ATLAS 550 unit, use the following procedure.
The IMUX-56/64 module cannot be installed into anATLAS 550
chassis without being first attached to anATLAS 550 option
module.

Instructions for Installing the IMUX-56/64 Module
Step Action
1
On the rear of the ATLAS 550 chassis, remove the cover plate
covering the slot into which the option module carrying the IMUX-
56/64 module is to be inserted.
If theATLAS 550 option module is already in the ATLAS 550
chassis, simply loosen the thumbscrews at both edges of the
option module faceplate and slide the module out of the chassis.
2
Carefully align the P10 connector on the IMUX-56/64 module with
the J10 connector on the option module.
Using only fingertip pressure, so that neither circuit board bends
or flexes, ensure that the connectors are firmly seated.
Secure the opposite end of the IMUX-56/64 module to the option
module using the screws and standoff posts supplied.
3Slide the option module, with the IMUX-56/64 module attached,
into the ATLAS 550 chassis until the module is positioned firmly
against the front of the ATLAS unit.
4Fasten the thumbscrews at both edges of the option module
faceplate. Tighten with a screwdriver.
5Install any additional modules into the base unit, as specified in
the
Installation chapter of the ATLAS 550 User Manual .

POWER-UP AND INITIALIZATION
After installing the IMUX-56/64 Module into the ATLAS 550 chassis, the
front panel STATUS indicator blinks red, yellow, and green for a time. The
STATUS indicator remains solid green when the IMUX-56/64 Module is
ready to use. At this time, you can invoke a system self-test; refer to the AT-
LAS 550 User Manual for details.
FAILED SELF-TEST
The terminal menu self-test log records any self-test failures for the IMUX-
56/64 module. Resources that fail self-test are disabled after power-up ini-
tialization is complete. Performing a hardware-level reset via the terminal
menu may recover these failed resources.
This self-test sequence may take up to eleven (11) minutes.

Chapter 3 Operation
OVERVIEW
You can configure and control the IMUX-56/64 Module from two sources,
as shown in Table 3-1. The ATLAS User Manual provides detailed instruc-
tions on operating each of the supported management approaches. The re-
mainderofthischapterdescribesthemenuitemsavailableformanagingthe
IMUX-56/64 Module using the terminal menu.
TERMINAL MENU STRUCTURE
ATLAS uses hierarchical menus to access all of its features. The top-most
menu level leads to submenus which are grouped by functionality. All sub-
menu options display in the VT-100 terminal window.
You can use the Modules terminal menu to configure and control the
IMUX-56/64 Module. The Modules menu option, Type,shows the IMUX-56/
64 Module as IMUX (see Figure 3-2). The following sections describe the Mod-
ules menu and its submenus.

You must have the appropriate password level to edit items using
the terminal menu. (See the section Access Passwords in the
ATLAS User Manual for detailed information on working with
passwords.)
Security level 1 users can view and edit every available field.
Security level 5 users can view any field, but they cannot edit.
Each menu description in this section indicates the required
password level required for write and read access.
