Troubleshooting

DCC dialup connection cannot be set up because the modem does not dial when the router forwards data.

Check that:

• The modem and phone cable connections are correct, and the modem initialization process is correct.

• The dialup interface, if it is synchronous/asynchronous, is set to operate in asynchronous protocol mode.

• DCC is enabled on the dialup interface.

• A dialer route or dialer number command is available for the packets.

The remote end cannot be pinged after the modem is connected.

Check that:

• The same link layer encapsulation is used at the two ends, and correct PPP parameters are configured for authentication. Use the debugging ppp all command to verify that.

• A correct IP address is assigned to the dialup interface (physical or dialer interface).

• DCC is enabled on the dialup interface.

• The correct dialer-group and dialer-rule commands are configured and associated to make sure that the packets can pass.

• Use the debugging dialer event and debugging dialer packet commands to locate the problem.
