Thanks very much for the input. You were correct. After working on this
one for a while, it was discovered that the customer was still plugging
away on trying to get their (Digi's) proprietary 128k bonding to work with
the PM3. :) Oh well... It's one of those situations that required prying
and prodding to get everything worked out. However, you were right on the
mark. I hope that this info may help some others out there.
Thanks again.

This message is a bit old, but I don't think you got any responses yet.
It looks like the Datafire is trying to establish a two-channel
connection, I would attempt to get a single channel one going first--much
easier to debug. I don't know anything about the DataFire, so make sure
that it is not trying to use a proprietary 128K/bonding mode which some
TAs have.
We are sending out the LCP_CONFIGURE_REQUEST and not getting back a
response (or at least one that is invalid). The "Bad PPP Address" means
we received a packet with an invalid address byte in the PPP frame. This
should be set to 0xff but we are receiving something else from the remote.
The only time when this can be set other then to 0xff ("All-Stations
Broadcast") is if it has been pre-negotiated during the LCP_CONFIGURE
phase (which doesn't even appear to have started if the above output is
complete).
Try the suggestions in the first paragraph, turning off anything that
looks like a "non-standard" option and cutting it back to a single
channel. It is either has a really messed up LCP implementation or is
expecting something else of its own making on the other end.. ;)
