Whoops! I had my lab glasses on... Yes, yes, HDLC will default and should
work fine... (PPP buys you more than just authentication, though, but not
much in the lab). It hadn't occurred to me that he might have backed off to
HDLC while troubleshooting. D'oh!
I agree though that it looks like it could be a switch problem. I would like
to see the q.921 output though...
