Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document contains the minimum technical requirements to ensure compatibili
16、ty of products and conformance with radio regulations across ETSI member states. Radio terminals from different manufacturers are not required to interwork at radio frequency (i.e. no common air interface). The present document defines the requirements for radio-relay equipment and associated interf
17、aces. The present document is intended to cover a variety of systems designed for a variety of services, applications, performance objectives and deployment conditions. Therefore it is necessary to include in the present document different sets of system parameters. In the present document these set
18、s of parameters are referred to as “system types“. In addition to the changes resulting from Public Enquiry, following the publication of CEPTERC Recommendation 74-01 2, clauses 2,5.3.3, 5.4.2 and 7.3 have been modified. The present document has been editorially modified after vote to maintain coher
19、ence with the other radio standards produced by ETSI Technical Committee Transmission and Multiplexing. The former title of the present document was: Transmission and Multiplexing (TM); Digital Radio Relay Systems (DRRS); Frequency Division Multiple Access (FDMA); Point-to-multipoint DRRS in fi-eque

By means of P-MP systems the network service area m
22、ay be extended to cover both distant and scattered user locations; and the systems may be applied to build new access networks covering both urban and rural areas. Users are offered the full range of services by the particular public or private network. Users have access to these services by means o
23、f the various standardized user network interfaces (2-wire loop, new data services and ISDN). P-MP systems provide standard network interfaces and transparently connect users to the appropriate network node. These systems allow a service to be connected to a number of users ranging from a few to sev
24、eral thousands and over a wide range of distances. Point-to-Multipoint systems are generally configured as Pre-Assigned Systems or as Demand Assigned Multiple Access (DAMA) Radio Systems. The essential features of a typical P-MP DAMA Radio Systems are: efficient use of the radio spectrum; concentrat
