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

25、ion; transparency. Radio is often the ideal way of obtaining communications at low cost and almost independent of distance, and difficult topography. Moreover, a small number of sites are required for these installations, thus facilitating rapid implementation and minimizing maintenance requirements

26、 of the systems. Concentration means that m users can share n radio channels (m being larger than n), allowing a better use to be made of the available frequency spectrum and at a lower equipment cost. The term “multi-access means that every user has access to every channel (instead of a fixed assig

27、nment as in most multiplex systems). When a call is initiated one of the available channels is allocated to it. When the call is terminated, the channel is released for another call. Concentration requires the use of distributed intelligent control which in turn allows many other operation and maint

28、enance functions to be added. Transparency means that the exchange and the user equipment communicate with each other without being aware of the radio link. ETSI 7 ETSI EN 301 373 V1.2.1 (2001-02) 1 Scope 1 .I Appl cat ions The present document covers the following point-to-multipoint applications:

Frequencies The present document covers fixed point-to-multipoint services operating in the 1,5 GHz, 2,2 GHz, 2,4 GHz and 2,6 GHz bands. The frequency plans for the 1,5 GHz, 2,2 GHz and 2,6 GHz bands are given in CEPTERC Recommendatio

30、n T/R 13-01 i. For the 2,4 GHz band, the ITU-R Recommendation F.701-2 li is applicable. 1.3 Access Method The present document covers Frequency Division Multiple Access (FDMA) systems. 1.4 Com pati bility There is no requirement to operate a Central Station (CS) from one manufacturer with a Terminal

31、 Station (TS) or a Repeater Station (RS) from another manufacturer. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present documen t.
