14、national Electrotechnical Commission) together form a system for worldwide standardization as a whole. National 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 particu
15、lar fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other 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 establi
16、shed a joint technical committee, ISO/IEC JTC1. The main task of a technical committee is to prepare International Standards but in exceptional circumstances, the publication of a technical report of one of the following types may be proposed: type1, when the necessary support within the technical c
17、ommittee cannot be obtained for the publication of an International Standard, despite repeated efforts; type2, when the subject is still under technical development requiring wider exposure; type3, when a technical committee has collected data of a different kind from that which is normally publishe
18、d as an International Standard (“stateofthe art”, for example). Technical reports of types1 and2 are subject to review within three years of publication, to decide whether they can be transformed into International Standards. Technical reports of type3 do not necessarily have to be reviewed until da
19、ta they provide are considered to be no longer valid or useful. ISO/IEC TR9578, which is a technical report of type3, was prepared by ISO/IEC JTC1, Information technology.iv blankISO/IECTR9578:1990(E) BSI 04-2000 1 Introduction This Technical Report deals with connectors for communication systems. F
20、or a number of years, communications interfaces defined by ISO have used interface connectors which had been or are being standardized by IEC. This Technical Report briefly defines connectors that are primarily used in International Standards for local area networks, which may also be used in wide a
21、rea networks and municipal area networks. It should be clearly understood that the data on connectors given in the International Standards merely provides reference information for particular applications. The final responsibility for connector standards lies with IEC. This subject of connector stan
22、dards has caused some misunderstanding in the past and it is hoped that this Technical Report will minimize the confusion as work proceeds on new open system interconnects related to local area networks. It should assist those not fully conversant with electrical connector technology to use the corr
23、ect components in their systems. The connectors described in this Technical Report are divided into three groups, according to the three transmission media currently defined for local area networks, that is to say copper wire/twisted pair, coaxial and fibre optic media, where the standards are avail
24、able and appropriate. 1 Scope This Technical Report describes the physical layer connection device for local area networks. This device is sometimes referred to as the medium interface connector and is used between the terminal equipment and the trunk coupling unit for the trunk cable. The connector
25、s described in this document were proposed by ISO/IEC JTC1 SC6, SC13, SC83, IEC TC46, IEC TC48, and IEC TC86. This document focuses the work of all of these groups into one compendium which describes the physical devices which are currently available in the standards world. Data transmission techniq
26、ues can be divided into two basic classifications: baseband and broadband. They can be further defined by the speeds of the data transmission across the interface. To avoid undue complexity, no attempt is made to describe the cable or wire used in conjunction with the connectors that are described.
27、2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this Technical Report. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this Techn
28、ical Report are encouraged to investigate the possibility of applying the most recent editions of the standards listed below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO4903:1980, Data communications15-pin DTE/DCE interface connector and pin assignments.
