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

13、technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. 2) In the field of information technology, IS0 and IEC have established a join

14、t technical committee, ISO/IEC JTC 1. Draft international Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. 3) Attention is drawn to the p

15、ossibility that some of the elements of this International Standard may be the subject of patent rights. IS0 and IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC and IS0 technical committees is to prepare International Standards. In exceptional ci

16、rcumstances, a technical committee may propose the publication of a technical report of one of the following types: 0 type 1, when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts; type2, when the subject is still under technical deve

ISOAEC 10192-2, which is a technical report of type 2, was prepared by subcommittee 25: Interconnection of information technology equipment, of ISO/IEC joint technical committee 1 : Information technology.

24、n devices and a home network in the Home Electronic System (HES). The SI type 1 connects simple devices offering and accepting only a two state signal to an HES home network. Two signals are available at the SI type 1. One is a control signal for turning the device on and off. The other is a monitor

25、 signal for checking the state of the device.

It is one of the family of Process Interfaces. The basic reference model for the SI type 1

38、is the same asfor all Process Interfaces (see figure 1). The difference from other PIS lies in the different services offered to the device via the SI type 1.
