Re: v.24 transport over ethernet

Yes, it needs one of those pins to come up to send the data I think and sync up. I'd say play with the dip switches on the v.24 card. I think 50% is the clocking and the other 50% is flipping what way the port sees the cable on the station.

The dial-peer for the router should point to the other router. So if you are on 1.141 your session targets should point to 1.142 and vice versa.

Good point on the unsupported commands as well. I knew there was another reason for the 28xx vs the 26xx for doing this work.

Timing. The serial server must support synchronous data. Most of those (the 10 second glance - it wasn't easy to quickly see if one did it or not) do not support that. The Cisco and Juniper etc. routers handle high speed serial data connections like T1, T3, etc., which are synchronous.
