3.1.4 Question 11/16 Summary
The group had as a goal to complete the work on a draft new Recommendation that defines Procedures for the end-to-end connection of analogue PSTN text telephones over an IP network utilizing text relay (V.151). A second goal was to complete the text of a new Amendment to V.150.1 that supports V.151 and also adds new SPRT data types. On completion of discussing several Delayed contributions it was agreed by the group to create a new corrigendum to V.152 to add clarification and correct editorial errors. The Question plans to hold one interim meeting.
3.1.5 Question 14/16 Summary
The group had as a goal to review and address maintenance issues against the T-series Recommendations within its sphere of responsibility. Several Delayed contributions were presented against T.38. These were reviewed and it was agreed not to submit a new version of T.38 for consent at this meeting. Rather, it was agreed to collate the accepted changes to T.38 into a single document that would be a living list of baseline text. Contributions to future meetings addressing or commenting on this baseline text are requested. The Question plans to hold one interim meeting.
3.1.6 Question 15/16 Summary
At this meeting, Q15/16 finalized the draft Corrigendum 1 to Recommendation G.767 for consent. Advance was also made in the work for the enhancement of G.769. Two contributions, one to report the quality evaluation results to emphasize the merit of channel multiplexing scheme in IP-CME, and another to propose the method for the end-to-end QoS parameters notification for NGN terminals. Regarding the work on drafting I.733, the group agreed to postpone the decision whether terminate drafting work or not, since submission of contributions at expected interim meeting was suggested. The Question plans to hold one interim meeting.
3.1.7 Question 16/16 Summary
Further progress was made on drafting text for revised ITU-T Rec. G.168 (Echo Cancellers) and new ITU-T Rec. G.160 (Voice Enhancement Devices). G.168 is planned for Consent in November 2006. G.160 was planned for Consent at this meeting but it was agreed that the text was not sufficiently stable. Instead, a work plan was developed to address the issues for Consent of G.160 at a later date. One liaison statement was sent to SG12requesting the development of a new objective test method for evaluating the voice quality of noise reduction functions. One interim meeting is proposed for 30 August to 5 September 2006.
3.1.8 Question 17/16 Summary
At this meeting, Q.17 reviewed three incoming LSs and produced two outgoing LSs. Three delayed contributions were discussed. The question agreed to version 1.4 of the draft G.IP2IP, and the living list of G. 799.1/Y.1451.1 was updated. The Question is planning one interim meeting 30 August – 5 September 2006.
3.1.9 Question 18/16 Summary
The purpose of the meeting was to advance the work on draft new Recommendation Q.115.2 “Logic for the control of Voice Enhancement Devices/Functions”, draft new Recommendation G.mdcspne “Mechanism for dynamic coordination of SPNE”, draft revised Recommendation G.161 "Interaction aspects of signal processing network equipment" for consent in 2006 and draft new Recommendation G.UCPSPNE about “SPNE mechanisms/auxiliary functions” for consent in 2007.
