TRY THIS
1. Verify that your ISP (Internet Service Provider) supports 2 channel ISDN (128K).
Some ISPs support ISDN on one 64K channel. Verify you have the correct ISDN
phone number (with the ISP).
2. Verify the Express 3000 configuration (using this guide).
3. Verify the initialization string is correct in your computer for your operating
system (refer to Remote Access Settings on page 3 for more details).
Note: If the Express 3000 has an active data call, the unit will not be available through
the ADTRAN Express Configuration software or Windows Device Manager.
THEN
Check the Express 3000 status buffer messages by completing the following steps:
1. Launch the ADTRAN Express Configuration software (ships with the unit) by
selecting PROGRAMS > ADTRAN > ADTRAN EXPRESS CONFIGURATION. Select
the DIAGNOSTICS menu (on the left side of the window). Click the STATUS BUFFER
button (for the Local Unit) and a list of the status buffer displays. Clear this buffer
by clicking the CLEAR BUFFER button. Close the buffer window by clicking the
CLOSE button. Exit Express Configuration Software by clicking EXIT.
2. Attempt your outbound call again.
3. Launch the ADTRAN Express Configuration software and display the status
buffer messages (see Express Configuration Software Installation on page 2).
4. Review the status messages. The entries are in reverse order, with the most
recent entry displayed on line 1. Check the sequence of events for the
connection for a DIAL 2 error message.
ED_MISMATCH followed by Disconnect 2 indicates that the ISP was unable
to bring both ISDN calls together and disconnected the second call. Try a
different access number or contact your ISP.
NORMAL_CLEARING followed by Disconnect 2 indicates that the ISP
blocked and disconnected the second call. Some ISPs limit ISDN service to
64K during times of high traffic. Try a different access number or contact your
ISP.
Telephone company messages are in upper case and have underscores
between words (for example, NETWORK_BUSY, NO_ROUTE_TO_DEST, and
INCOMPATIBLE_DEST). Refer to the manual provided on the Express 3000
CD for error messages definitions.
NOTE: The PHONE 2 LED on the Express 3000 will illuminate orange during an
outgoing call attempt. These steps assume the PHONE 2 LED is illuminating but
the data call does not successfully negotiate. If the PHONE 2 LED does not
illuminate during an outgoing call attempt, refer to the troubleshooting steps in
SYMPTOM:ADTRAN Express Configuration or Windows Device Manager is
unable to locate the Express 3000 on page 4.
TRY THIS
1. Verify the number dialed is an ISDN number.
2. Verify the initialization string is correct in your computer for your operating
system (refer to Remote Access Settings on page 3 for more details).
NOTE: If the initialization string you enter in Windows does not save, the Windows
registry is not working properly. Please contact Technical Support for your
computer or operating system for help with this problem.

NO_ROUTE_TO_DEST, and INCOMPATIBLE_DEST). Refer to the manual
provided on the Express 3000 CD for error message definitions.
NOTE: If there are no entries in the status buffer, the dialer you are using (normally
Windows) is not communicating with the Express 3000. Check the setup of
your dialer and verify that it is configured to use the Express 3000.
TRY THIS
1. Disconnect power from the Express 3000.
2. Unplug the ISDN line from the back of the unit.
3. Connect power back to the Express 3000.

4. After the Express 3000 powers up, wait at least 30 seconds and place SWITCH 2
in the ONposition (switch pointing down).
5. If the PHONE 1 and 2lights remain off, reconfigure the unit. If the PHONE LEDs
illuminate again, contact ADTRAN Technical Support (see Contact Information
on page 6).
6. Reapply the ISDN profile or reconfigure the device.
