December I996 ISSN 031 7-5669 Reference number ISO/IEC 13575:1995(E) ISO/IEC 13575:1995(E) Foreword IS0 (the International Organization for Standardization) and IEC (the Inter- national Elec
4、trotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of techn
5、ical activity. IS0 and IEC technical corn- mittees collaborate in fields of mutual interest. Other international organ- izations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint t
6、echnical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for vot- ing. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. International Standard ISO/lEC

10、face between data terminal equipment DTE) and data circuit terminating equipment (DCE). It is applicable where the functional characteristics of the interface conform to CCllT Recommendation V.24 and the electrical characteristics conform to ITU-T Recommendation V. 12. 2 Normative references The fol
11、lowing ITU-T (CCllT) Recommendations and International Standards contain certain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All ITU-T (CClrr) Recommendations and International
12、Standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the sta nda rdslreco m m end at i ons indicated below.

16、iguration of contacts in a component. 3.3 female contact : A contact intended to make electrical engagement on its inner surface. 3.4 intermateable connectors : Two connectors that are capable of being connected to each other electrically and mechanicatly without regard to their performance. 3.5 lat
17、ching device : A feature incorporated in certain components to provide mechanical retention of their mating parts. 3.6 electrical engagement on its outer surface. male contact : A contact intended to make 3.7 seating plane : The surface that the connector bottoms on when fully mated. 4 Connector A 5
18、0-pole connector shall be provided for the DTE/DCE interface. Figures I to 4 illustrate the connector. Only those dimensions that are essential for mating are shown. The DTE-DCE interface point is defined at the point between the cable connector associated with the cable attached or wired to the DTE
19、 and the equipment connector associated with the DCE (see figure 5). Figure 1 illustrates the cable connector which has 50 male contacts in a connector housing. Figure 2 illustrates the equipment connector which has 50 female contacts in a connector housing. The connector housing on the equipment co
20、nnector is dimensioned to fit inside the connector housing of the cabte connector (see figures 3 and 4). Figures 3 and 4 give contact numbering and illustrate the dimensions and latching mechanism for the cable and equ i pm ent connectors respectively. 1 ISO/IEC 13575:1995(E) 102 P02a 102b 0 ISO/IEC
