Matt, Thanx for the ISDN 101 class, But I already understand how ISDN
works, Hell I should hope considering I do run all of Internet access here
I'm trying to predict the behavior of the MAX under certain
configuration settings. As we both know the Max doesn't always perform
as spec'd out in the RUBB. (Really Useless Big Book)

It should be quite easy to get the Max to do the particular call routing
that I am looking for, 

Have the max call route on a special treament basis, If the incomming 
call doesn't match the flag set (the second MSN#). Then treat it as 
an ordinary call. If it does match the rule set, Then port it directly to
the HDLC call.
