The problem with combining 2 ISDN channels like this
(known as multilink) is that there is no actual (ITU)
standard for it.
Both ends of the connection must use the same protocol
for combining the info from both B channels to one data
stream, as it seems that TInet and you have a mismatch
I actually haven't tried multilink to any ISPs only
between my own ISDN switches so I can't give you any
specific pointers in this regard. All I can say is
that the cheapo ISPs like IOL/Indigo/TInet just don't
know anything about ISDN.
