Tunnel Async Data
VER A 7/23/03
As an example, assume that async RS-232 devices are to be connected by leased line modems. Instead, the leased line modems are replaced with Cisco comm servers. Plug the RS-232 devices into async lines on the Cisco comm servers and connect the comm servers via an arbitrary topology IP network. In this sample configuration, one side is the caller and the other side is the called. It is presumed that the caller side is more persistent in its desire to send data.

The caller side has an IP address of 10.224.8.3 and is using Line 2.
The called side has an IP address of 10.226.x.1 and is using Line 3.
