X25 Transpac connection on B-channel with CAPI 2.0

Hello,

I am looking for some explanations on how to establish a X25 connection with
a Transpac server (in France) on a B-channel with CAPI 2.0. I have the
number to call ("called number" = 08 36 08 64 64) and the Transpac number of
the server that I would reach. I have also the protocols specifications of
the final server, and I can communicate with it. But my questions are on the
connexion step with the X25 access point (before the link to the final
server) :
- What are the correct configurations to use for each protocol : B1, B2, B3.
I think it is HDLC for B1, LAP-B for B2 (but how to select it in CAPI 2.0
?), and X25 for B3 (but X25 DTE-DTE or X25 DCE in CAPI 2.0 ?).
- What is the way to transmit the Transpac number after the dial operation ?
- What are the answer (s) of the access point after the dial operation ? And
after the Transpac number transmission ?
- Is it possible to get an example code in C/C++ of a similar operation ?

Many thanks in advance.

Best regards,

Bruno MANILLIER.
