Troubleshooting
Symptom 1
DCC dialup connection cannot be set up because the modem does not dial when the router forwards
data.
Solution
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.
