¿µ¹®³»¿ë¿ä¾à The present document describes the Physical Layer(PL) and the Data Link Layer(DLL) of the Air Interface(AI) as well as the standardized services and facilities of the radio. Radio equipments which conform to the present document shall be interoperable at the PL and DLL with equipment from other manufacturers.
The present document describes 2 levels of functionality(services and facilities) that can be offered by the equipment. For the purposes of interoperability, a basic level of services and facilities(ISF) is defined along with a simplified mode of addressing such that all radios will be capable of interoperating without the need for any set-up or programming at the point of sale. An advanced level of services and facilities(CSF) is also defined for those equipments that can be re-programmed to offer a higher level of functionality.
