ITU Telecommunication Standardization Sector Document APC-1722 Study Group 16 Version 1 Q12-14/16 Rapporteur Meeting 4 October 1999 Red Bank, 18-22 August 1999 Source: ITU-TSB (Frank Cohen) Title: Terminology difference between T.35 and H.225.0 Purpose: Information _______________________ From: "Cohen, Frank" To: "'ccaron@mediatrix.com'" Cc: "Bigi, Fabio" ,"'Staudinger, Wilhelm'","'Silbiger, Herman'","'okubo@giti.or.jp'" Subject: RE: t35CountryCode, t35Extension and manufacturerCode in the H221Non Standard sequence (in H.225) Date: Mon, 4 Oct 1999 14:47:48 +0200 MIME-Version: 1.0 Dear Mr. Caron In response to your message, ITU-T Study Group 16 when developing its H221Non Standard Sequence used a different terminology than the one used by ITU-T Study Group 8 when that Study Group developed T.35. Therefore, the"t35Extension" of H.221should be considered the "provider code"of T.35, and the "manufacturerCode" of H.221should be considered the "provider oriented code" of T.35. Since the administration of Canada has not informed us that they have chosen a national body for the assigning of the provider code, it is they you will have to turn to for that code.
