Troubleshooting Diagnostic Commands
If a data connection could not be established, you might be able to
determine the cause through the AT command interface.
Follow the steps listed below:
•
Close all data applications.
Otherwise, these applications might start a retry command that will
interrupt your troubleshooting efforts.
•
Unplug and re-connect the data cable.
This terminates any ongoing data connections.
•
Establish basic computer-to-modem communication.
For instructions, see “Establishing Communication” on page 72.
•
Query the last “Extended Error Code”.
Although you might not be able to see the text as you type it, you should
see a result code returned to you.
Extended Error Result Codes
Extended error result codes report the network reason why a data
connection failed. If you report a failed connection to technical support, be
sure to provide the code. See the following table for a list of the extended
error result codes that the modem can return.
