National

41、 bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Ot

42、her international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rul

43、es given in the ISO/IEC Directives, Part 3. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires app

44、roval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 13239 was

ISO/IEC 13239:2002(E) vi ISO/IEC 2002 All rights reservedIntroduction This third edition adds a new frame format

47、type to Annex H Frame format types. This frame format type is used in those environments where additional error protection, identification of both the source and the destination(s), and/or longer frame sizes are needed. High-level data link control (HDLC) procedures are designed to permit synchronou

48、s or start/stop, code-transparent data transmission. The normal cycle of the code-transparent data communication between two data stations consists of the transfer of frames containing information from the data source to the data sink acknowledged by a frame in the opposite direction. Generally, unt

49、il the data station comprising the data source receives an acknowledgement, it holds the original information in memory in case the need should arise for retransmissions. In those situations that require it, data sequence integrity between the data source and the data sink is effected by means of a numbering scheme, which is cyclic within a specified modulus and measured in terms of frames. An independent numbering scheme is used for each data source/data sink combination on the data link. The acknowled
