Troubleshooting

Symptom
Modem is in abnormal status (for example, the dial tone or busy tone keeps humming).
Solution
•
Use the shutdown command and undo shutdown command on the device physical interface
connected to the modem to check whether the modem has been restored to normal status.
•
If the modem is still in abnormal status, repower the modem.
