Howard's words are right on the mark. Here is the link to the
Cisco page you were looking for:
http://www.cisco.com/warp/public/133/3.html
I made a post a while back on this very topic. I tested the
actual throughput of X.25 using various parameters on a V.35
link. The bottom line is that it never really got much higher
than 140-145kBps when the line was clocked at 4Mbps. The
overhead was much too high. I never really tested the
throughput of XOT (X.25 over TCP), or running X.25 over an
Ethernet segment. It might be something to do on a Saturday if
one had some spare time :-) Still, the basis for doing that
seems somewhat irrelevant, because ultimately I would expect
the X.25 somewhere to be transiting a WAN link. In that
regard, you will still have a bottleneck.
HTH,
