18、the present document. Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). National transposition dates Date of adoption of this EN: 4 July 2003 Date of latest announcement of this EN (doa): 31 October 2003 Date
19、 of latest publication of new National Standard or endorsement of this EN (dop/e): 30 April 2004 Date of withdrawal of any conflicting National Standard (dow): 30 April 2004 Introduction The main field of application of Point-to-Multipoint (P-MP) systems is to provide access to both public and priva
20、te networks (Public Switched Telephone Networks (PSTN), Private Data Networks (PDN). By means of P-MP systems the network service area may 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. U
21、sers are offered the full range of services by the particular public or private network. Users have access to these services by means of the various standardized user network interfaces (2 wire loop, new data services and Integrated Services Digital Network (ISDN) ranging from basic rate to n primar
22、y rate). 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 several thousands and over a wide range of distances. P-MP systems are generally configu
23、red as Pre-Assigned Multiple Access (PAMA) radio systems or as Demand Assigned Multiple Access (DAMA) radio systems. The essential features of a typical P-MP radio system are: - efficient use of the radio spectrum; - concentration; - transparency. ETSI ETSI EN 301 021 V1.6.1 (2003-07) 6 Radio is oft
24、en the ideal way of obtaining communications at low cost and almost independent of distance, and over difficult topography. Moreover, a small number of sites are required for these installations, thus facilitating rapid implementation and minimizing maintenance requirements of the systems. Concentra
