Re: Auto Answering

I'm not completely clear on the problem; but with regard to the AA light being on, and the modem not answering;

1. Check to make sure the DTR is asserted. Make sure the modem has its DTR light on, otherwise it wont answer. The Cisco 1600 asserts this line, but it is possible your cable doesn't carry this signal.

Also, you have specified a "dialer-group" command, but have not declared a dialer interface.
