Troubleshooting
How to Troubleshoot Connection Problems continued
Symptom: Remote Module unexpectedly disconnects from Switch Card
Reason for Disconnect
Lost Carrier
Possible Cause
Either the modems dropped the line due to errors, or the remote module dropped the analog phone line or digital terminal.
Action
Check the Statistics tab to view any unusual or excessive errors and refer to tables on pages
Reset the stats after the remote user connects. Use the Make Busy feature in the Switch Management Interface to prevent new connection attempts. When the user is dropped, expectedly or unexpectedly, a complete detail of that one connection will be visible. Make Busy will actually prevent further connections until cleared. If the problem seems to be excessive modem errors lower the “Connect Rate” on the remote module.
If there are no unusual or excessive errors on the Statistics tab, the problem is probably caused by a cabling problem on the remote module. Either the digital terminal or the analog line on the remote module appears to have been disconnected. Disable specific features, such as call waiting, on the remote modules analog line.
