residential environment. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio or TV reception,
which can be determined by turning the equipment off and on. The user is
encouraged to try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from

CANADIAN EMISSIONS REQUIREMENTS
This digital apparatus does not exceed the Class B limits for radio noise
emissions from digital apparatus as set out in the interference-causing
equipment standard entitled "Digital Apparatus," ICES-003 of the Depart-
ment of Communications.
Cet appareil nuerique respecte les limites de bruits radioelectriques
applicables aux appareils numeriques de Class B prescrites dans la norme
sur le materiel brouilleur: "Appareils Numeriques," NMB-003 edictee par le

CANADIAN EQUIPMENT LIMITATIONS
Notice: The Canadian Industry and Science Canada label identifies
certified equipment. This certification means that the equipment meets
certain telecommunications network protective, operational, and safety
requirements. The Department does not guarantee the equipment will
operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permis-
sible to be connected to the facilities of the local telecommunications
company. The equipment must also be installed using an acceptable
method of connection. In some cases, the company’s inside wiring
associated with a single line individual service may be extended by
means of a certified connector assembly (telephone extension cord). The
customer should be aware that compliance with the above conditions
may not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Cana-
dian maintenance facility designated by the supplier. Any repairs or
alterations made by the user to this equipment, or equipment malfunc-
tions, may give the telecommunications company cause to request the
user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground
connections of the power utility, telephone lines and internal metallic
water pipe system, if present, are connected together. This precaution
may be particularly important in rural areas.
Caution: Users should not attempt to make such connections them-
selves, but should contact the appropriate electric inspection authority,
or an electrician, as appropriate.
The Load Number (LN) assigned to each terminal device denotes the
percentage of the total load to be connected to a telephone loop which is
used by the device, to prevent overloading. The termination on a loop
may consist of any combination of devices subject only to the require-
ment that the total of the Load Numbers of all devices does not exceed
100.

Chapter 1. Introduction
Before getting started, review the section Minimum Requirements
in this chapter to ensure your computer is compatible. In
addition, examine the contents of the box to ensure everything
has been received undamaged and gather the required setup
information provided by your telephone company.
MINIMUM REQUIREMENTS
What You Provide
In order to operate the Express XR/ XRT the following is re-
quired:
• A computer (386 or higher PC, or Macintosh)
• Windows 3.1 or higher for PC
• 16550 UART high speed serial port (16650 UART required for
data speed of 230.4 kbps)
• RS-232 serial cable with a DB-25 connector for the Express XR/
XRT and the other end matching the COM port on the com-
puter (Do not use a null modem cable)
• One Basic Rate ISDN line (Two ISDN phone numbers, some-
times referred to as local directory numbers)
Single ISDN phone number and point-to-point lines are not recom-
mended for use with the XRT.
Basic Rate ISDN Line
When ordering your ISDN line from the telephone company,
request EZ-ISDN 1 (Capability Package U) to ensure it is set up
properly. EZ-ISDN 1 is recommended by the industry for most
home office/ small business applications. If EZ-ISDN is not
available from your service provider order Generic Data M. For
more information regarding ordering ISDN, see the ADTRAN
document Ordering ISDN Service User Guide part number
60000.015-8, or contact the telephone company for alternative
line configurations. The Ordering ISDN Service User Guide is
available on the ADTRAN home page at http://www.adtran.com

Installation
INSTALLING THE ADTRAN EXPRESS XR/XRT
This section describes how to connect the Express XR/ XRT to a
PC and how to install the Express Configuration Wizard soft-
ware.
Verify Switch Settings
Dip switches 1 and 2 located on the rear panel of the Express
XR/ XRT allow certain settings to be physically configured.
Figure 2-1 shows the location of the dip switches on the rear
panel of the unit.
The factory default position for all switches is down (On) during initial
installation.
SW 1: Off (Up)
=
230.4 kbps
On (Down) = Autobaud (speeds up to 115.2 kbps)
If switch 1 is set to the Off position, the unit is set to operate at a
DTE speed of 230.4 kbps. A special serial COM port using a
16650 UART is required while in this mode. If switch 1 is set to
the On position, the unit will automatically adapt to the DTE
rate (up to 115.2 kbps).
In order to configure the Express XR/XRT to operate at 230.4 kbps
with Windows 95 or Windows NT 4.0 Dial-Up Networking, a new
modem must be added from the Modems icon in the Control Panel.
Enter the name for this new connection and select ADTRAN Express
XR or XRT 230.4 Kbps & 16650 UART. See the section Installing
Windows 95 Dial-Up Networking.

Basic Telephone Service
In addition to the computer connection, two analog devices such
as a telephone, FAX, modem, answering machine, or caller ID
box can be connected using the two POTS interfaces on the rear
panel (RJ-11 jacks labeled 1 and 2 with a diagram of a telephone
above the jack).
Supplementary Voice Services
Supplementary services such as call forwarding, caller ID, call
return, call holding, three- or six-way conference, call transfer,
and call waiting are fully supported by the Express XR/ XRT on a
touch-tone telephone. These services are available only if in-
cluded in the ISDN line configuration and are implemented
using the standard commands provided by the telephone
company.
Call Waiting
Call Waiting permits one voice call to be placed on hold while
answering another voice call. Use the flash-hook to place the
active call on hold and answer an incoming call. Hanging up
terminates both calls. The call waiting tone can be disabled and
enabled using a touch-tone phone as follows:

Chapter 2. Installation
Conference Calling
Conference Calling (also known as three-way calling) permits a
conversation between three parties, each at different locations.
During a voice call, the call waiting tone signals a second incom-
ing call. Flash-hook to place the first call on hold and answer the
incoming call. Flash-hook again to retrieve the first caller. A
third flash-hook conferences all three parties.
Automatic Redial
Automatic redial dials the last number dialed. This can be
accomplished using a touch-tone phone as follows:
Redial last number: Press ** 5
When connecting to a National ISDN 1 switch, call conferencing and
call transferring are assigned a unique feature identifier number. This
number may not be the same in all areas. S-registers 90 and 91 contain
the feature identifier numbers for conference and transfer. If these
features do not work, contact your ISDN provider.
Phone Number Allocation
The Express XRT allocates ISDN phone number 1 to POTS port
1. Connect the primary telephone to POTS port 1 as shown in
Figure 2-2.
ISDN phone number 2 is shared by the RS-232 port and POTS
port 2, therefore only one can be used at a time.
ISDN data calls and external modem applications must be placed to
ISDN phone number 2.
Single Phone Number Operation
For AT&T 5ESS point-to-point lines and other lines with a single
phone number, incoming voice calls are routed to POTS port 2 to
allow for use of either a modem or a telephone. Service on POTS
port 1 is not available.

Configuring an External Analog Modem
If the modem does not support 230.4 kbps, Switch 1 on the back
panel of the Express XRT must be On (down) to install and use
an external modem with the Express XRT. This limits the DTE
speed to 115.2 kbps when using the Express XRT with an exter-
nal modem. To re-enable the 230.4 kbps operation for ISDN
connections, set Switch 1 to the On position.
When using applications supporting Express XRT operation at
230.4 kbps with an external analog modem that does not support
230.4 kbps, attach the Express XRT to the high speed 16650
UART COM port and connect the external modem to a separate
COM port. This allows the Express XRT to operate at 230.4kbps
and the external modem to operate at the reduced speed.
Required External Analog Modem Settings
There is one setting in the external modem that is required
before trying to enable the modem with the Express Configura-
tion Wizard. The Carrier Detect signal from the modem should
be set to Normal (track the CD signal). This can be accom-
plished by using the AT command AT&C1. AT commands can
be entered into the modem using the following procedure:

Controlling an External Analog Modem
There are three options for enabling and disabling an external
modem: the Express Configuration Wizard, the WIN 95/ NT 4.0
Tool Tray Icon, or a terminal emulation package. See the section
Express Configuration Wizard Tray Tool for more information on
enabling and disabling a modem.
Once the external analog modem is enabled, all further COM
activity is transmitted to the external analog modem connected
to the Express XRT modem port. The external analog modem
RTS and CTS lines are switched over to the PC COM port
directly when the Express XRT is commanded to enable the
external modem port. This allows the external analog modem to
provide flow control as normal.
When the external analog modem is disabled, all further COM
port activity is processed by the ISDN terminal adapter within
the Express XRT.

Application Configuration
There are three methods available for configuring the Express
XR/ XRT: Express Configuration Wizard, VT 100 terminal, or AT
Commands.
Before configuring the Express XR/ XRT for any application, the
Express XR/ XRT should be connected correctly for the applica-
tion as described in the chapter Installation.
Some features in the Express XR/ XRT do not take effect upon
selection. This prevents unintentional reconfiguration of the
Express XR/ XRT during an active call. Items such as Bit Rate,
Protocol, and Call Type take effect only at the beginning of a new
call.
Technical notes, documents and scripts can be found on the
ADTRAN web home page at http://www.adtran.com under the
Information Desk. These provide information on how to use
ADTRAN products in specific applications on PC and Macintosh
platforms.

Troubleshooting
TROUBLESHOOTING GUIDELINES
This section provides troubleshooting techniques to possible
problems that may be encountered while operating the Express
XR/ XRT. If problems persist contact ADTRAN technical support
for assistance (see the back cover of this manual).
Power/Line LED is Off
Indicates a problem with the power to the unit. Verify the power
cord is connected to the Express XR/ XRT and is plugged into a
known working 120 volt AC electrical outlet.
Power/Line LED Flashes and B1 and B2 LEDs are Off
This indicates a problem with the physical connection of the
ISDN line from the local telephone company to the Express XR/
XRT.
1. Verify the large end of the RJ-45 to RJ-11 telephone cable
(included with the Express XR/ XRT) is connected to the
ISDN connector on the rear panel of the Express XR/ XRT.
2. Verify the small end of the RJ-45 to RJ-11 telephone cable is
connected to the ISDN telephone wall jack installed with
Basic Rate ISDN.
3. Contact the local telephone service provider.

Chapter 5. Troubleshooting
Power/Line LED, B1, and B2 LEDs Flash Green
This indicates a configuration problem. Verify the following
information is correct:
• Switch Type
• Service Profile Identifiers (SPIDs)
• ISDN Phone Numbers
This information can be viewed by choosing the Status Register
button under the Diagnostics tab of the ADTRAN Express
Configuration Wizard window or the Configuration Screen in
the VT 100 menu system. The Link Status should indicate Link
Up if all configuration information is correct and the unit is
properly connected. If the link status is good and calls still can
not be placed, review the section for Dial-Up Connection Problems.
Auto-Detect can be used under the Wizard button in the AD-
TRAN Express Configuration software (or by using the Auto-
Detect SPIDs/Switch option in the Configuration screen of the
VT 100 menus) to automatically detect the SPIDs and the Switch
Type.
Look for the following with the COM port setup:
• IRQ conflicts.
• Wrong DTE speed.
• Use Microsoft diagnostics (msd.exe) to verify the COM port
has 16550 UART (for speeds of 115.2 kbps and below) or a
16650 UART (for speeds up to 230.4 kbps).
• Proper COM driver is installed (not provided) to support DTE
speeds above 19.2 kbps.
Verify the correct protocol is selected:
• PPP or V.120 generally for Internet applications
• V.120 or Async BONDING for work-at-home
Dial-Up Connection Problems
Many connection problems can be diagnosed by viewing the
status buffer message returned from the ISDN network and the
Express XR/ XRT. These messages are accessed by choosing the
Status Buffer button in the Diagnostics tab of the ADTRAN
Express Configuration window.

Chapter 5. Troubleshooting
The Status buffer can also be accessed using the key sequence
Ctrl+V in the VT 100 menu system. Issue the AT command
AT!V from a terminal emulation package such as HyperACCESS
to invoke the VT100 menu system.
Auto-detect Switch/SPIDs Remains at Link Down
The Link Down condition persisting for longer than 15 minutes
indicates a problem with the ISDN line provided from the
telephone company. The ISDN physical layer device has not
been able to synchronize to the network. Ensure the RJ-45 to RJ-
11 telephone cable is correctly installed between the Express XRT
and the ISDN wall jack and that the Express XR/ XRT is powered
on. If the wall jack does not have ISDN installed on the two
middle pins (tip, ring), the Express XR/ XRT will never synchro-
nize to the telephone switching equipment. Call the local
telephone company and have them check the ISDN line for
correct operation.
Express XR/XRT Not Detected
If the Express Configuration Wizard cannot detect the Express
XR/ XRT verify the following:
1. The Express XR/ XRT is powered on.
2. No other Windows applications are running that could be
using the COM port to which the Express XR/ XRT is
attached. A Windows application does not have to be active
to tie up a COM port, be sure to check the Windows 95
Taskbar for any suspended applications (such as
HyperTerminal and HyperACCESS) that may be using the
COM port. If any are minimized, these must be closed
before starting the Express Configuration Wizard.
3. If you are operating the Express XR/ XRT at 230.4 kbps,
ensure that switch 1 on the rear panel is off. This is required
for operation at 230.4 kbps. Also, confirm that the computer
has a 16650 UART.

Chapter 5. Troubleshooting
External Analog Modem Not Detected
If the Express Configuration Wizard cannot detect the external
analog mode verify the following:
1. The external analog modem is powered on.
2. The external analog modem is properly installed and
configured for use with the Express Configuration Wizard.
See Configuring an External Modem for more details on the
required settings.
Difficulty with 230.4 kbps Operation
If the Express XR/ XRT does not work when the DTE rate is set
to 230.4 kbps inside Windows, verify the following:
1. Verify that switch 1 on the back of the Express XR/ XRT is
set to off (up).
2. Verify that a high speed serial card with a 16650 UART is
being used and the software drivers to support the extended
baud rate tables are installed.
Dial-Up Networking Difficulty
If Windows 95 Dial-Up Networking cannot talk to the Express
XR/ XRT, check the modem configuration for the Express XR/
XRT. Ensure the bit rate for the DTE is set correctly. If the PC is
not equipped with a 16650 UART then the fastest DTE operation
speed is 115.2 kbps. Ensure the speed is not higher than the PC
and modem can support.

Appendix A
AT Commands and S-Registers
AT Commands
While a call is not established, the DTE port accepts AT com-
mands. During this time, the CD signal is inactive. When a call
is established, the port is used for data. This data mode is
indicated by the CD signal active. The Express XR/ XRT can be
configured and controlled with AT commands from a serial port
similarly to analog modems.
To exit data mode and enter command mode, the serial port
must transmit a proper escape sequence to the Express XR/ XRT.
A specified time delay must occur between the last data charac-
ter and the first escape sequence character. This is the guard
time delay, and it can be changed by writing a value to the S12
register. The default value for the guard time is one second. For
a valid escape sequence to occur, the DTE must transmit the
escape code character three times in succession with delay
between each character being less than the guard time. The
default escape sequence is +++.
Once command mode is entered, AT commands can be transmit-
ted to the Express XR/ XRT to configure most of the options, dial
remote Express XR/ XRTs, or initiate tests to check both the
Express XR/ XRT and the network connections. All command
lines must begin with the AT character set in either capital or
lower case letters. To return an active call to the on-line state
type ATO.
The command line may contain a single command or a series of
commands after the AT attention code. AT commands _L1 and
_L0 are exceptions and must be on a separate line followed by
Enter. When a series of commands are used, the individual

Appendix A. AT Commands and S-Registers
commands may be separated with spaces for readability. The
maximum length for a command line is 40 characters. Each
command line is executed by the Express XR/ XRT upon receipt
of a terminating character. The default terminating character is a
carriage return (ASCII 013), but it can be changed by writing a
different value to register S3. Before the terminating character is
transmitted, the command line can be edited by using the
backspace character (ASCII 008) to erase errors so the proper
commands can be entered.
Using an AT Command
Type AT followed by the letter of the command and numeric
value of the setting desired and then press Enter. The following
command returns the software version of the unit:
ATI1
Using S-Registers
The configuration of the Express XR/ XRT can be changed or
reviewed with S-registers. See the section S-Register List in this
