We have a DIVA board and we need to receive a LAPD digital data call.
I believe I should choose the appropriate DivaCallType when using DivaAnswer(). However, I cannot find a LAPD choice.
These are the digital data types I found:
DivaCallTypeDigitalData (plain HDLC) DivaCallTypeX75, DivaCallTypeV120, DivaCallTypeX25.
The requirements of our peer:
(First, our peer sends a User-User-Info in the SETUP signal to declare that he wants to create a data transfer in the B-channel. We reply with another UUS in an ALERT signal.)Then, our peer will create a data-link with the LAPD protocol (balanced protocol of the HDLC family). It will initiate the procedure by emittinga SABME frame. It will follow ETS 300 125 : User-network interface data link layer specification; Recommendations Q.920/I.440 and Q.921/I.441He will be network side, while we should be user side.The parameters for the connection are: SAPI = 15 TEI = 0 Window = 7 Modulo = 128Do we have to set these parameters? Where should we set these parameters?
