Dear T.120 experts,

Following the Q.1 Rapporteur meeting in Shenzhen last March, some of the ASN.1 syntax were questioned while Q.1 was reviewing a proposed draft revised T.135.

After consultation with the ASN.1 Project Group of SG17, the TSB ASN.1 Specialist and the Editor of T.135, we received some suggestions and were able to understand the small corrections still needed to allow the T.135 ASN.1 to compile without errors. We prepared what should be the final version of T.135 to be submitted as a TD.

The changes from the version that you saw at the Shenzhen Rapporteur meeting are the following:

- on some constraints on AcknowledgmentType, "WITH COMPONENTS" was added; - in a comment a string like "------------" shall contain an even number of "-" character.

The attached draft contains change marks. Please review it and let me know if you have any comments before we submit the draft to the upcoming SG16 meeting.

Best regards,

Patrick Luthi Rapporteur for Q.1/16
