no, i didn't try it. All the MLPPP i searched about initially on the
net referred only to Internal ISDN cards. So i just ingored mppp then.
so, while reading (man 8 pppd) i may have missed it out. But, while
reading another post, i remember someone saying "with external TA, u
have to configure only the TA for MLPPP, while using pppd to connect.
the pppd - mlppp conversion is done by the ext. TA."

Do i need to dial twice (my pppd script has connect 'chat -v ...' in
it), or just after dialing once, use pppd -detach /dev/ttys0.
Also, how do i check if my kernel has MPPP support? I said, its 2.4
and its just the same which the installation program installed. I
haven't recompiled it.

Somehow, today i managed get get someone on line at the ISP support.
They said u just require one phone line to have 128K. I think, u
require two lines (2pairs in the incomming cable with 4 pins on the
RJ11 jack). Also, the telephone charges get doubled.
But when i checked the incomming telephone line, i just saw 1 pair of
copper cable and the jack had just 2 pins! Is this OK? does the 2B in
BRI indicate two distinct frequency channels and not physical
channels? Even if this is the case, do i get two telephone numbers for
the 2B channels? I have just 1 telephone number.

Has nebody tried squid for windows? is it stable? will it perform
better than Win+NAT(builtin)

As i said, the setup is at coll (closed today), i'll reply with the
results tommorow. ne way, John, can i mail you, if i have ne problems
then? (i'll post here also).
