Modem to Router issue

[wlamo]

I realize I might be in the wrong place since I do not believe my question falls under this catagory but I thought maybe someone can point me in the right direction. I have a US Robotics modem that all the default dip switches are thrown including auto-answer however when it is attached to my Adtran Router and I dial into it the phone just rings and rings. Is there something I'm missing?

Thanks ahead for any responses.

Hmm, Have you looked here:

Are you talking about a VOIP setup, or something else? If the issue seems to be more with the Telephony side of things, I'd suggest starting in the above forum.

no VoIP just a simple console session into an Adtran Router. The Modem is in Auto-Answer but the Router is not picking up. This is a typical Hyper-Term configuration I would think.

The Adtran doesn't send an answer command (ATA) to the modem. The modem has to auto-answer.... I would double-check the dip switches. If the modem isn't going offhook at all, it's something on the modem, not the Adtran.

When you dial the modem, you should see the "AA" light blinking with each ring. If you don't, then you may have an REQ issue; where not enough voltage is getting to the modem on ring to trip the circuit.

By default, the modem is NOT set to auto-answer. If all of the dip switches are in the "Default" settings, then you should just have to flip the AA dip switch to the "other" state.

I read somewhere I need a Null Modem cable, is that correct?

Not if you're connecting to a modem. A null-modem cable crosses over if you're connecting two DCE devices directly. (taking the modem out of the loop, therefore "null modem")
