Because Layer 2 to the switch was already up, MULTIPLE-FRAMES-ESTABLISHED,
and 3 was trying to come up. So, I figure, if 3 is trying to come up and
cannot that there is another issue and ppp is easier, in my opinion, to
troubleshoot than hdlc.

Leah,
If the call isn't even connecting to the other side how is debugging PPP
going to help?
