Modem Configuration Problems

3 When the access server receives the call, verify that the dial-in modem is detecting

data terminal ready (DTR). Usually, there is a light on the modem marked DTR or

TD. Most modems will not answer without this signal.

4 If the modem is not detecting DTR, the modem cable might be faulty. Replace the

cable and retry.

5 If the modem is detecting DTR, but it is not answering the telephone, then either the

modem is not functioning correctly or it is not configured for autoanswer. For more

information, refer to the modem documentation.

6 Verify that the access server port hardware is working correctly. See the section

Verifying a Port for Hardware Failure (page 10-8).
