H.245v6 ASN.1 tree?

Paul,
The only change to the syntax for V6 that I am aware of is the change given
below (from TD69/PLEN of Santiago), where ** is used to label additions.
MediaTransportType ::=CHOICE
{
ip-UDP NULL,
ip-TCP NULL,
atm-AAL5-UNIDIR NULL, -- virtual circuits used as unidirectional
atm-AAL5-BIDIR NULL, -- virtual circuits used as bidirectional
...,
** atm-AAL5-compressed SEQUENCE
** {
** variable-delta BOOLEAN ,
** ...
** }
}
At the Berlin meeting there were discussion regarding the T.38 fax
codepoints - we had received a liaison from SG8 that showed that there were
differences between T.38 Annex B and H.245 V5. We replied to them suggesting
a syntax addition to H.245 (V6) to allow the additional fields in T.38 Annex
B to be signalled. I am assuming that we will not include these changes in
H.245 until we have received a response from SG8.
I have not made a new syntax - it did not seem worth the effort - and I am
not aware of anyone else doing so.
Best regards
Mike
