Chuck,
I believe your first problem is with your cabling. You will need a DCE
cable on the Cisco side coupled together with your DTE cable connecting
to the 3com side.
If you're only going to use the two routers I don't believe you will
have much success setting the Cisco up as a frame switch. You would
need at least two routers hanging off the 2500 in order to switch
to/from. However, you can setup PPP encapsulation between the two and
you then should have a valid back-to-back config.

Subject: OT - 3Com router back-to-back with 2500
Anyone,
I've got a 3Com Netbuilder II router I'm trying to use back to
back
with a 2500 router. I'm using the V.35 port on the 3Com, and a standard
sync serial on the Cisco. The cable is a V.35 DTE, so the 3Com should
be
providing the clock. I want to try frame relay, using the Cisco as the
frame switch. But the interfaces stay down on both sides. I've told
the
3Com to be the DCE side, using the clock - test mode setting. I tried
using
PPP on both sides as well, but I think it's a signaling problem, not a
frame
or PPP problem. Has anyone done this before? On the Cisco side, I've
got
DCD=down DSR=down DTR=up RTS=up CTS=down. I'm not sure what the 3Com is
showing, because I'm not really sure where to find that. Any help would
be
appreciated.
TIA,
Chuck Church
