Dear Q.12/16 broadband system experts, The Sunriver experts group meeting agreed to correct the H.320/H.321 interoperation mode stack of H.310 RAST-5 terminals and to apply this correction to H.310 Version 1. This agreement was reported to WP1&2/16 meeting on 12 September and the guidance obtained there was to use the procedure defined in Section 8.7.2 of Resolution No. 1 (Geneva, 1996) as attached. I need to submit a white contribution containing the proposed changes. I intend to use Annex to APC-1300 for this purpose. As this is a rather heavy (very visible to everybody) procedure, I need your cooperation to review thoroughly the Annex to APC-1300 so that our correction is defectless. Please return your advice as soon as possible, by 7 October at the latest. Then I will send the white contribution to Geneva for reference in the Director's invitation to the January-February meeting of SG16. Best regards, Sakae OKUBO (Mr.) ******************************************************************** Graphics Communication Laboratories Phone: +81 3 5351 0181 6F ANNEX TOSHIN BLDG.

This Guide is an historical document recording all identified defects and their status of correction, from their identification to final resolution, and would be issued in the Study Group's COM Series of documents. 8.7.2 Defects identified since the approval of the latest issue of the Implementors' Guide (par. 8.7.1) and their proposed corrections are referenced in the Director's invitation to the next Study Group meeting so the Study Group can address them. The Chairman shall be accountable for a fair decision about the nature of the proposed corrections, in the spirit which is expressed in par. 8.5.2 above. After approval by the Study Group (see par. 8.5.3 to par. 8.5.6), the Director shall announce the corrections in a Circular-letter and the Study Group will update the Implementors' Guide accordingly.
