Chapter 1 Introduction
ASYNC-232 MODULE OVERVIEW
The Async-232 Module combines with other ATLAS components to provide solu-
tions for a variety of wide area networking applications. Providing sixteen asyn-
chronous EIA-232 DTE ports, the Async-232 Module serves as the interface to
terminal servers and other DTE equipment. Each port of the Async-232 Module
can be configured to operate at any standard asynchronous rate up to 115.2 Kbps.
For remote access applications, ATLAS receives incoming analog or ISDN-based
signals from remote users, concentrated onto T1 or primary rate ISDN circuits.
These calls are processed and directed to the Async-232 Module via ATLAS’ inter-
nal bussing system. As with all ATLAS components, configuration can be accom-
plished through a variety of mechanisms, including Telnet or VT-100 emulation.
SNMP management is supported for alarm and event reporting.
Functional Description
The Async-232 Module installs into any available option slot in the ATLAS chas-
sis. The ATLAS front panel displays the status of the module itself, as well as the
circuits to which it interfaces. In addition, the terminal menu gives further status
information, allows you to configure the Async-232 Module, and downloads
application software.
Features
The following list describes the Async-232 Module features:
• Sixteen asynchronous interfaces at speeds up to 115.2 Kbps
• Incoming and outgoing analog modem and ISDN call support when used in
conjunction with the ATLAS Modem-16 Module
• AT command set
• DTR dialing
• Performance monitoring including the following:
- DTE signals
- I/O statistics
- Call status and statistics
• Hot swappable

ASYNC-232 MODULE SPECIFICATIONS
Each port of the Async-232 Module conforms to the specifications given in
Table 1-1.
Physical Description
Two DB78 to octal DB25 cables make the physical connection. A label below each

Chapter 2 Installation
UNPACK AND INSPECT
Carefully unpack and inspect the Async-232 Module for any shipping damages. If
you suspect damage has occurred, immediately file a claim with the carrier and
then contact ADTRAN Technical Support. If possible, keep the original shipping
container for returning the Async-232 Module for repair or for verification of
shipping damage.
Contents of ADTRAN Shipments
The ADTRAN Async-232 Module shipment includes the following items:
• Async-232 Module
•Async-232 Module User Manual (Insert into the main ATLAS Manual.)
• Two DB78 to Octal DB25 Cables
INSTALLING THE ASYNC-232 MODULE
The Async-232 Module plugs into any available option slot. Figure 2-1 depicts the
action required for proper placement of the Async-232 Module, as described here:
1. Remove the cover plate from the option slot into which the Async-232 Mod-
ule will be installed (located on the ATLAS chassis rear panel).
2. Slide the Async-232 Module into the option slot until the module is firmly
positioned against the front of the ATLAS chassis.
3. Fasten the thumbscrews at both edges of the Async-232 Module.
4. Connect the DB78 end of the cable to the Async-232 Module, and connect the
DB25 connector to the associated devices.
5. Complete installation of the remaining modules and base unit, if necessary, as
specified in the Installation chapter of the ATLAS User Manual.

WIRING
Each Async-232 Module port provides a single DB25 DCE connector. The connec-
tor pinout is given in Table 2-1.
.
POWER-UP AND INITIALIZATION
When the Async-232 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 Async-232 Module are automatically restored upon power-up.
When the Async-232 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.

Failed Self-Test
If the self-test fails, both the LCD on the ATLAS front panel and the terminal
menu report this event. The LCD displays an error message reporting the failure,
and the terminal menu self-test log records the same error message. See the ATLAS
User Manual for details. Appendix C, Failure Messages, of this document lists the
specific failure messages.
Operational Alarms
The front panel LEDs and the red ALARM LED illuminate when an alarm condi-
tion is detected.

Chapter 3 Operation
OVERVIEW
You can configure and control the Async-232 Module from a variety of sources,
as shown in Table 3-1.
The VT-100 terminal is attached to the control port of the ATLAS Base Unit, and a
Telnet session is established through the Ethernet port of the ATLAS Base Unit.
Chapter 3 of the ATLAS User Manual provides detailed instructions on the operation
of each of the management approaches listed in Table 3-1.
The remainder of this chapter describes the menu items available when managing
the Async-232 Module via the terminal menu.
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 sub-
menu options display in the VT-100 terminal window.
Refer to the ATLAS User Manual for detailed instructions on how to navigate
through the terminal menu.
MENU ACCESS
The ATLAS System Controller automatically detects the presence of the Async-
232 Module when it is installed into the Base Unit. To access the Modules Menu
options, use the keyboard arrow keys to scroll to the Modules menu and press
Enter. Then, for example, to view the Menu submenu for the ASYNC-16, use the
keyboard arrow keys to move to the row ASYNC-16 and the column Menu; then

ASYNC-232 MENU DESCRIPTION
The following paragraphs (Slt (slot), Type, Menu, Alarm, Test, State, Status, and
Rev (revision)) describe the Modules menu options (see Figure 3-1).
Figure 3-1. Modules Menu
Slt (Slot)
Read security: 5
Displays the number of all the available slots in the ATLAS chassis. Slot 0 refers
to the ATLAS base unit. This field is read-only.
Type
Write security: 3; Read security: 5
Displays the module type installed in the slot or the module type you plan to
install in the slot. If an Async-232 Module is installed, the Type field automati-
cally defaults to Async-16. You can use this field to preconfigure a system before
installing modules by specifying the module that you want to install into each
slot.
If a module is installed, the module type automatically displays the name of the
installed module, and it cannot be set to any other option.
Menu
Read security: 5
Displays additional status and configuration menus for the selected module. (To
access the submenus for this item, use the arrow keys to scroll to the Menu col-
umn for the module you want to edit, and press Enter.)

ASYNC-232 Menu Description Chapter 3. Operation
61200182L1-1 Async-232 Module User Manual 3-3
Alarm
Read security: 5
Displays whether there is an alarm condition on the Async-232 Module. Press
Enter in this field to activate the Alarm menu.
Test
Read security: 5
Displays whether the Async-232 Module is executing a test. Press Enter in this
field to activate the Test menu.
State
Read security: 5
Displays whether the module is online or offline. Even though a module is phys-
ically installed, its status must be marked Online for it to be considered an avail-
able resource. Marking an installed module Offline may be useful in system
troubleshooting. If you choose Offline, the module will not be in alarm condition,
but will display Offline.
Only if State reads Online can the ATLAS use an installed module for any data
bandwidth.
Status
Read security: 5
Displays status information on the Async-232 Module. Table 3-2 describes status
messages, and their meanings, that may appear.
Rev (Hardware Revision)
Read security: 5
Read-only field that displays the hardware revision of the Async-232 Module.
Table 3-2. Async-232 Module Status Messages
Message Meaning Comments
Online The module is enabled and is respond-
ing to the system controller’s status
polls.
This is the normal response of
the system.
No Response The module is enabled but is not
responding to the system controller’s
status polls.
This response indicates either a
problem in the system or the
module is not installed.
Empty The system controller has not detected
the presence of a module in the option
slot, nor has a module been manually
enabled for this option slot.
Offline The module is installed but has been
taken Offline by a user.
The module is still responding
to controller polls.
Offline /
No Response
The module is installed but has been
taken Offline by a user. The module is
not responding to polls.
