2811 serial connection to a modem

Answered Question
Feb 14th, 2008

Hi There;

I'm looking for an example interface script for an asynchronous RS422 serial connection from a 2811(DTE) to a modem(DCE). How do I route the traffic to the modem? For instance, am I required to give the modem an ip address to act as the next hop?

Regards

I have this problem too.

You don't route traffic to the modem, just like you don't route traffic to your phone line. The connection is strictly layer1.

> For instance, am I required to give the modem an ip address to act as the next hop?

You can assign an IP address to certain modems for remote management purposes, however these modems have a dedicated port for such tasks, they don't use the serial port.
