Chapter 1 Introduction
MODEM-16 MODULE OVERVIEW
The Modem-16 Module combines with other ATLAS components to implement a
high-capacity modem pool in the ATLAS Integrated Access System. The Modem16 Module, which occupies a single slot in the ATLAS chassis, supports sixteen
K56flex modem calls or sixteen ISDN connections. Using the ATLAS Async-232
Module provides remote users with dial-in access to external equipment through
EIA-232 ports. ATLAS provides support for up to 48 modem or ISDN users per
system. Figure 1-1 shows a sample application of the Modem-16 Module.
Modem module supports sixteen 56k analog or sixteen ISDN calls
Figure 1-1. ATLAS Remote Access Application
FUNCTIONAL DESCRIPTION
The Modem-16 Module installs into any available slot in the ATLAS 800 chassis.
The status of the module itself, as well as the circuits to which it interfaces, can be
viewed from the ATLAS front panel. 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 Modem-16 Module can be configured and application software can be downloaded using the terminal menu.

Chapter 2 Installation
UNPACK AND INSPECT
Carefully inspect the Modem-16 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 Modem-16 Module for repair or for verification of shipping damage.
Contents of ADTRAN Shipment
The following items are included in the ADTRAN shipment:
• Modem-16 Module
• Modem-16 Module User Manual (insert into main ATLAS User Manual)
INSTALLING THE MODEM-16 MODULE
The installation procedure is described below, and Figure 2-1 shows the proper
placement of the option module.
1. Remove the cover plate (corresponding to the slot in which the Modem-16
Module will be installed) from the ATLAS chassis rear panel.
2. Slide the Modem-16 Module into the ATLAS chassis until the module is posi-
tioned firmly against the front of the ATLAS unit.
3. Fasten the thumbscrews at both edges of the option module.
4. Complete installation of remaining modules and Base Unit as specified in the
61200181L1-1 Modem-16 Module User Manual 2-1
Installation chapter of the ATLAS User Manual.

Chapter 2. Installation Power-Up and Initialization
Failed Self-Test
POWER-UP AND INITIALIZATION
When the Modem-16 Module is inserted into the ATLAS chassis, the front panel
STATUS indicator blinks red, yellow, and green for a time. Previously configured
settings for the Modem-16 Module are automatically restored upon power-up.
When the Modem-16 Module is ready for operation, the STATUS indicator
remains solid green. At this time a system self-test can be invoked, as described
in ATLAS User Manual.
This startup sequence may take up to two minutes.
Failed Self-Test
The terminal menu self-test log records self-test failures for the Modem-16 Module. Analog resources which fail self-test are disabled after power-up initialization is complete. Performing a hardware reset via the terminal menu may recover
these failed resources.

Chapter 3 Operation
OVERVIEW
You can configure and control the Modem-16 Module from several sources, as
shown in Table 3-1. The ATLAS User Manual provides detailed instructions on
operating each of the supported management approaches. The remainder of this
chapter describes the menu items available for managing the Modem-16 Module
using the terminal menu.
Table 3-1. Management Methods for the Modem-16 Module
Source Purpose
ATLAS Front Panel For minimal configuration and status support
Terminal Menu For detailed configuration, status, and diagnostics
Simple Network Management Protocol (SNMP)
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.
TERMINAL MENU STRUCTURE
ATLAS uses a form of hierarchical menus to access all of its features. The top-most
menu level leads to submenus which are grouped by functionality. All submenu
options display in the VT-100 terminal window.
You can use the Modules terminal menu to configure and control the Modem-16
Module. The Modules menu option, Ty pe , shows the Modem-16 Module as
M56K-16 (see Figure 3-1). The following sections describe the Modules menu and
its submenus.

MENU ACCESS
The ATLAS System Controller automatically detects the presence of the
Modem-16 Module when it is installed in the system. To access the Modules
menu and submenus, use the keyboard arrow keys to scroll to the appropriate
row and column; then press ENTER on the keyboard. For example, to view the
Menus submenu for M56K-16, use the keyboard arrow keys to move to the row
M56K-16 and the column Menu; then press ENTER on the keyboard.
Refer to the ATLAS User Manual for detailed instructions on how to navigate
through the terminal menu.
MODEM-16 MENU DESCRIPTIONS
The following paragraphs (Slt (slot), Type, Menu, Alarm, Test, State, Status, and
Rev (revision)) describe the Modules menu and submenus.
Slt (Slot)
Read security: 5
Displays the number of available slots in the ATLAS chassis. Slot 0 refers to the
ATLAS Base Unit.
Type
Write security: 3; Read security: 5
Displays the module type currently installed in the slot or the module type you
plan to install in the slot. If a Modem-16 Module is installed, the Typ e field automatically defaults to M56K-16 (the Modem-16 Module). You can use this field to
preconfigure the system before installing modules by specifying the module that
you want to install into each slot.

ATLAS FEATURES USED WITH MODEM-16 MODULE OPTIONS
In addition to the Modem-16 Module menu items, two additional ATLAS menu
items may be operated in conjunction with the Modem-16 Module. These are Fac-
tory Restore and System Self-test.
Factory Restore
You can restore the factory default settings for the Modem-16 Module by pressing
F on the keyboard while the cursor is positioned over the Slt number (this restores
the factory settings for all of the module options) or while the cursor is positioned
over an individual field (this restores factory settings only for the particular field).
System Self-Test
System Self-test, a submenu of the ATLAS main menu item System Utility, executes both the Modem-16 Module internal test and the ATLAS internal test. The
results of the self-test are displayed in the LCD. For additional information on
self-test, see the ATLAS User Manual.
When System Self-test displays, place the cursor on it and press ENTER to execute the test. The unit continuously changes the display on the self-test log screen
until all test results are shown.
