How to Troubleshoot Connection Problems continued
Symptom: Remote Module unexpectedly disconnects from Switch Card
Reason for
Disconnect
Possible Cause Action
Lost Carrier Either the modems
dropped the line due
to errors, or the
remote module
dropped the analog
phone line or digital
terminal.
Check the Statistics tab to view
any unusual or excessive errors and
refer to tables on pages 6-16 to
6-18.
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.
