(ASCEND) No IP connection between Max and Pipeline - but why not???



Hi,

Last week we (finally) configured our ISDN connection between my
pipeline and a Max. After some configuration troubles, we finally got
it working fine.

Until today, but I'm at a loss why. 

I'm calling to our Max, which validates via CHAP and calls me back:

May 26 21:38:27 6Q:egwene ASCEND: slot 2 port 1, Outgoing Call, xxxxxxx
May 26 21:38:28 6Q:egwene ASCEND: slot 2 port 1, line 1, channel 2,
Call Connected, MBID 002
May 26 21:38:28 5Q:egwene ASCEND: call 2 OR slot 2 port 1 64K xxxxxx
May 26 21:38:28 6Q:egwene ASCEND: slot 2 port 1, LAN session up, cit
May 26 21:38:28 5Q:egwene ASCEND: call 2 CL 0K 
May 26 21:38:28 4Q:egwene ASCEND: slot 2 port 1, line 1, channel 2,
Call Disconnected
May 26 21:38:28 6Q:egwene ASCEND: slot 2 port 1, Call Terminated
May 26 21:38:28 6Q:egwene ASCEND: slot 0 port 0, LAN session down, cit

And of course, I'm awaiting that call, which arrives promptly. I'm
also using CHAP: 

May 26 21:38:44 6Q:egwene ASCEND: slot 0 port 0, line 1, channel 1,
Incoming Call, xxxxxxxxxx
May 26 21:38:44 6Q:egwene ASCEND: slot 2 port 1, Assigned to port,
xxxxxxxxx
May 26 21:38:44 6Q:egwene ASCEND: slot 2 port 1, line 1, channel 1,
Call Connected, xxxxxxxxx
May 26 21:38:44 5Q:egwene ASCEND: call 3 AN slot 2 port 1 64K
xxxxxxxxxx
May 26 21:38:45 6Q:egwene ASCEND: slot 2 port 1, LAN session up, cit

LAN session up, so I'm supposed to be in business, right? Wrong. 

When I ping the Max at the other end of the connection, I get total
package loss. Those systems simply don't see each other. 
However, earlier today it did work flawlessly - I didn't change the
configuration though!

Any suggestions how to find the cause of "sometimes it works, usually
not" behavior? I'm running 5.0A+, the Max runs 4.6c (or something like
that).
