needed changes to H.245 V4
by Dale L. Skran 01 May '98

01 May '98

As noted in the revised meeting report of the Yokosuka meeting, an error was made in agreeing to remove T.38 related references from H.245 V4. Doing so creates a set of forward references, and prevents the ITU-T from moving forward both H.323 Annex D and T.38 Annex B. Note the following: Determination Decision H.245 V4 Feb. 98 Sept 98 H.245 V5 Sept 98 April 99 H.323 Annex D Feb 98 Sept 98 T.38 Annex B June 98 Jan-Feb 99 It can be readily seen that, for example, H.323 Annex D cannot refer to H.245 V5 as this would be a forward reference. Please find attached needed changes to H.245 V4 as previously attached to the draft Annex D H.323. These changes *will not* be included in the H.323 Annex D as they should be in the H.245 white paper. Please contact H.245/Q14 Rapporteur Gary Thom with any questions. Dale Skran Rapporter Q13
