Troubleshooting

Symptom 1: Failure to establish a dialup connection

DDR dialup connection cannot be established because the modem does not dial when the router
forwards data.

Solution

To resolve the problem:
1. Verify that the modem and phone cable connections are correct, and that the modem initialization
process is correct.
Verify that the dialup interface, if it is synchronous/asynchronous, is configured as an
2.
asynchronous interface in protocol mode.
3. Verify that DDR is enabled on the dialup interface.
4. Verify that a dialer route or dialer number command is available for the packets.
