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 interfer-  
ence-causing equipment standard entitled "Digital Apparatus,"  
ICES-003 of the Department of Communications.  
Cet appareil nuerique respecte les limites de bruits radioelec-  
triques applicables aux appareils numeriques de Class B pre-  
scrites dans la norme sur le materiel brouilleur: "Appareils  
Numeriques," NMB-003 edictee par le ministre des Communica-

CANADIAN EQUIPMENT LIMITATIONS  
Notice: The Canadian Industry and Science Canada label identi-  
fies certified equipment. This certification means that the equip-  
ment 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 per-  
missible to be connected to the facilities of the local telecommuni-  
cations 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 (tele-  
phone extension cord). The customer should be aware that com-  
pliance with the above conditions may not prevent degradation of  
service in some situations.  
Repairs to certified equipment should be made by an authorized  
Canadian maintenance facility designated by the supplier. Any  
repairs or alterations made by the user to this equipment, or  
equipment malfunctions, may give the telecommunications com-  
pany 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 in-  
ternal metallic water pipe system, if present, are connected togeth-  
er. This precaution may be particularly important in rural areas.  
Caution: Users should not attempt to make such connections  
themselves, but should contact the appropriate electric inspection  
authority, or an electrician, as appropriate.

the percentage of the total load to be connected to a telephone loop  
which is used by the device, to prevent overloading. The termina-  
tion on a loop may consist of any combination of devices subject  
only to the requirement that the total of the Load Numbers of all  
devices does not exceed 100.

Installation  
INSTALLING THE ADTRAN EXPRESS XRT  
This section describes how to connect the Express XRT to a com-  
puter 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 XRT  
allow you to physically configure certain settings. Figure 2-1 on  
page 6 shows the location of the dip switches on the rear panel of  
the unit.  
The factory default position for all switches is On (down) during initial  
installation.  
SW 1:  
Off (up)  
230.4 kbps  
=
=
On (down)  
Autobaud (speeds up to 115.2 kbps)  
If dip switch 1 is set to the Off position (up), the unit is set to op-  
erate at a DTE speed of 230.4 kbps. A special serial COM port us-  
ing a 16650 UART is required while in this mode. If switch 1 is set  
to the On position (down), the unit will automatically adapt to the  
DTE rate (up to 115.2 kbps).  
In order to configure the Express 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 XRT 230.4  
Kbps & 16650 UART. See the section Installing Windows 95 Dial-Up  
Networking on page 23.

Basic Telephone Service  
In addition to the computer connection, two analog devices such  
as a telephone, FAX, modem, or answering machine can be con-  
nected 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 re-  
turn, call holding, three- or six-way conference, call transfer, call  
rejection, and call waiting are fully supported by the Express 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 an-  
swering 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 us-  
ing a touch-tone phone as follows:  
Disable call waiting: Press ** 0  
Enable call waiting: Press ** 1  
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.  
To enable Call Conferencing, dial **2 before dialing the telephone  
number. This enables the Flash Hook button on your telephone to  
conference up to six people together. The dial code is only neces-  
sary when S37=0, when S37=1, or when the Flash Hook button  
will conference by default.

Automatic Redial  
Automatic redial dials the last number dialed. This can be accom-  
plished using a touch-tone phone as follows:  
Redial last number: Press ** 5  
When connecting to a National ISDN 1 switch, call conferencing, mes-  
sage waiting, and call transferring are assigned a unique feature identi-  
fier 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 on page 7.  
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.

An external or internal analog modem can be connected to the Ex-  
press XRT to access an Internet provider, BBS, or host server that  
does not support ISDN.  
EXTERNAL ANALOG MODEM APPLICATION  
In order to connect an external analog modem to the Express XRT,  
the following items are necessary:  
• External analog modem  
• RS-232 serial cable  
• RJ-11 to RJ-11 telephone cable  
Incoming calls must use ISDN phone number 2 for external analog ap-  
plications.  
In addition to the RS-232 cable connecting the Express XRT to the  
PC, a separate RS-232 cable is required to connect an external an-  
alog modem to the Express XRT. This RS-232 cable is not sup-  
plied.

which the Express XRT is connected.  
If you are connecting a modem to the Express XRT that has al-  
ready been in use by Windows 95, you are ready to use the exter-  
nal analog modem. The external analog modem can be enabled  
either through the Express Configuration Wizard or by using a VT  
100 terminal emulation package. See the section Express Configu-  
ration Tray Tool Menu on page 22 for more information on en-  
abling and disabling an analog modem.  
If you are connecting an external analog modem that has not been  
previously in use by Windows 95, see the section Installing a New  
External Analog Modem on page 29.

Configuring an External Analog Modem  
If the modem does not support 230.4 kbps, dip 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 external  
modem. To re-enable the 230.4 kbps operation for ISDN connec-  
tions, set dip switch 1 to the Off (up) 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 230.4 kbps 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 Configuration Wiz-  
ard. The Carrier Detect signal from the modem should be set to  
Normal (track the CD signal). This can be accomplished by using  
the AT command AT&C1. AT commands can be entered into the  
modem using the following procedure:  
<cr> indicates to press the Enter key on the keyboard.  
1. Open a terminal emulation session using HyperACCESS or  
HyperTerminal.  
2. Type AT_L1 <cr>  
3. Type AT <cr>  
4. Type ATI <cr>  
5. Type AT &C1 <cr>  
6. Type AT&W <cr>

Controlling an External Analog Modem  
There are three options for enabling and disabling an external mo-  
dem: the Express Configuration Wizard, the WIN 95/NT 4.0 Tool  
Tray Icon, or a terminal emulation package. See the section Ex-  
press Configuration Tray Tool Menu on page 22 for more informa-  
tion on enabling and disabling a modem.  
Once the external analog modem is enabled, all further COM ac-  
tivity 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 mo-  
dem 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.  
Express Configuration Wizard Modem Enable  
Run the Express Configuration Wizard and select the Connect Ex-  
ternal Modem option under the Configuration tab. Figure 3-2 on  
page 32 illustrates the Express Configuration Wizard Connect Ex-  
ternal Modem option.  
See the section Express Configuration Wizard Tray Tool on page 19

tion.  
See the section Express Configuration Tray Tool Menu on page 22 for  
more information on disabling a modem.  
Terminal Emulation Modem Enable  
An alternative method of enabling/disabling an external analog  
modem is to use a terminal emulation package such as HyperAC-  
CESS. In order to determine if an external analog modem is prop-  
erly connected to the Express XRT, issue the AT command AT!Z  
(followed by Enter). If an external analog modem is properly con-  
nected to the Express XRT, the Express XRT responds with the  
message MODEM FOUND (shown in Figure 3-4 on page 34).  
The AT!Z command is directed to the Express XRT, not the analog  
modem itself. An ERROR occurs if the command is sent while the  
external analog modem is enabled.  
If the external analog modem is not properly connected to the Ex-  
press XRT, the Express XRT responds with the message NO MO-  
DEM FOUND.

Application Configuration  
There are three methods available for configuring the Express  
XRT: Express Configuration Wizard, VT 100 terminal, or AT  
Commands.  
Before configuring the Express XRT for any application, the Ex-  
press XRT should be connected correctly for the application as de-  
scribed in the chapter Installation on page 5.  
Some features in the Express XRT do not take effect upon selec-  
tion. This prevents unintentional reconfiguration of the Express  
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 ADT-  
RAN web home page at http://www.adtran.com under the Infor-  
mation Desk. These provide information on how to use  
ADTRAN products in specific applications on PC and Macintosh  
platforms.

Calls with Data 56k and Data 64k are routed with the RS-232  
port.  
Enable Call Rejection List  
Enabling this option configures the Express XRT to compare all  
incoming Speech and Audio calling party numbers to the list of  
ten numbers in the Incoming Voice Call Rejection List. If a match  
between the incoming calling party number and an entry in the  
Incoming Voice Call Rejection List is found, the Express XRT will  
not ring the POTS port. Generally the caller will experience a  
busy signal. A message in the Status Buffer is the only indication  
that a call has been rejected.  
Enable Anonymous Call Rejection  
This option enables rejection of calls where the calling party  
number is blocked. These numbers normally appear as Private  
on a Caller ID unit. When an incoming anonymous call is  
received, while Anonymous Call Rejection is enabled, the call  
will not ring the POTS ports. Generally the user will experience a  
busy signal. A message in the Status Buffer is the only indication  
that an anonymous call has been rejected.

Troubleshooting  
TROUBLESHOOTING GUIDELINES  
This section provides troubleshooting techniques to alleviate  
problems that may be encountered while operating the Express  
XRT. If problems persist contact ADTRAN technical support for  
assistance (see the back cover of this manual).  
Power/Line LED is Off  
This indicates a problem with the power to the unit. Verify that  
the power cord is connected to the Express XRT and is plugged  
into a known working electrical outlet. If the Euro ISDN switch is  
selected, this may also indicate that the power is on but the line is  
deactivated.  
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 XRT.  
1. Verify the large end of the RJ-45 to RJ-45 cable (included with  
the Express XRT) is connected to the ISDN connector on the  
rear panel of the Express XRT.  
2. Verify the other end of the RJ-45 to RJ-45 cable is connected to  
the ISDN NT1.  
3. Contact the local telephone service provider.

Chapter 6. Troubleshooting  
Power/Line LED, B1, and B2 LEDs Flash Green  
This indicates a configuration problem. Verify the following in-  
formation is correct:  
• Switch Type  
• Service Profile Identifiers (SPIDs) (used in North America  
only)  
• ISDN Phone Numbers  
This information can be viewed by choosing the Status Register  
button under the Diagnostics tab of the ADTRAN Express Con-  
figuration 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 con-  
nected. If the link status is good and calls still can not be placed,  
review the section for Dial-Up Connection Problems on page 55.  
Auto-Detect can be used under the Wizard button in the ADT-  
RAN Express Configuration software (or by using the Auto-De-  
tect SPIDs/Switch option in the Configuration screen of the VT  
100 menus) to automatically detect the SPIDs and the Switch  
Type. This only applies to North American switches.  
1. 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.  
2. Verify the correct protocol is selected:  
• PPP or V.120 generally for Internet applications  
• V.120 or Async BONDING for work-at-home  
Power/Line LED, B1, and B2 LEDs flash green sequentially. After a soft-  
ware upgrade, if the Power/Line, B1 and B2 LEDs flash green in se-  
quence, a problem occurred. Restart the download using the instructions  
in on page 49, If the download fails a second time, contact ADTRAN  
technical support.

Chapter 6. Troubleshooting  
Dial-Up Connection Problems  
Many connection problems can be diagnosed by viewing the sta-  
tus buffer message returned from the ISDN network and the Ex-  
press XRT. These messages are accessed by choosing the Status  
Buffer button in the Diagnostics tab of the ADTRAN Express  
Configuration window.  
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 in-  
voke the VT 100 menu system.  
Auto-detect Switch/SPIDs Remains at Link Down  
Auto-detect is only used in North America.  
The Link Down condition persisting for longer than 15 minutes  
indicates a problem with the ISDN line provided from the tele-  
phone company. The ISDN physical layer device has not been  
able to synchronize to the network. Ensure the RJ-45 to RJ-45 ca-  
ble is correctly installed between the Express XRT and the NT1  
and that the Express XRT is powered on. Call the local telephone  
company and have them check the ISDN line for correct opera-  
tion.  
Express XRT Not Detected  
If the Express Configuration Wizard cannot detect the Express  
XRT verify the following:  
1. The Express XRT is powered on.  
2. No other applications are running that could be using the COM  
port to which the Express XRT is attached. A Windows appli-  
cation does not have to be active to tie up a COM port. Be sure  
to check the Windows 95 Taskbar for any suspended applica-  
tions (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 XRT at 230.4 kbps, ensure that  
dip switch 1 on the rear panel is off (up). This is required for  
operation at 230.4 kbps. Also, confirm that the computer has a  
16650 UART.

Chapter 6. Troubleshooting  
External Analog Modem Not Detected  
If the Express Configuration Wizard cannot detect the external an-  
alog mode verify the following:  
1. The external analog modem is powered on.  
2. The external analog modem is properly installed and config-  
ured for use with the Express Configuration Wizard. See Con-  
figuring an External Analog Modem on page 30 for more details  
on the required settings.  
Difficulty with 230.4 kbps Operation  
If the Express XRT does not work when the DTE rate is set to 230.4  
kbps inside Windows, verify the following:  
1. Verify that dip switch 1 on the back of the Express 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  
XRT, check the modem configuration for the Express 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 XRT can be configured and  
controlled with AT commands from a serial port similarly to ana-  
log modems.  
To exit data mode and enter command mode, the serial port must  
transmit a proper escape sequence to the Express XRT. A speci-  
fied time delay must occur between the last data character 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 de-  
fault value for the guard time is one second. For a valid escape se-  
quence 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 XRT to configure most of the options, dial re-  
mote Express XRTs, or initiate tests to check both the Express XRT  
and the network connections. All command lines must begin with  
the AT character set in either capital or lower case letters. To re-  
turn 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 En-  
ter. When a series of commands is used, the individual com-  
mands may be separated with spaces for readability. The

Appendix A. AT Commands and S-Registers  
maximum length for a command line is 40 characters. Each com-  
mand line is executed by the Express XRT upon receipt of a termi-  
nating 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 transmit-  
ted, the command line can be edited by using the backspace char-  
acter (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 val-  
ue of the setting desired and then press Enter. The following com-  
mand returns the software version of the unit:

with S-registers. See the section S-Register List on page 63 for a de-  
scription of each S-register and its corresponding range of values.  
Reading an S-Register  
Type ATS followed by the number of the S-register to be read fol-  
lowed by a question mark and press Enter.

for stored phone numbers, SPIDs, etc. Type ATSS followed by  
the number of the string S-register to be read followed by a ques-  
tion mark and press Enter.  
ATSS80?  
Changing an S-Register
