24、uction The main field of application of Point-to-Multipoint (P-MP) systems is to provide access to both the Public Switched Telephone Network (PSTN) and private networks (Private Digital Network (PDN), particularly for remote subscribers. By means of P-MP systems the network service area may be exte
25、nded to cover both distant and scattered subscriber locations. These remote subscribers. in a similar manner to the city subscriber. are offered the full range of services by the particular public or private network. Subscribers have access to these services by means of the various standardized user
26、 network interfaces (2-wire loop, data, .). P-MP applications in the metropolitan and urban environment are mainly for the provision of new data services for business subscribers and for the extension of Integrated Services Digital Network (ISDN) services to local subscribers The frequency bands bel
27、ow 3 GHz are particularly suitable for the extension of telecommunications services to distant rural and suburban subscribers. P-MP systems provide standard network interfaces and transparently connect subscribers to the appropriate network node (local switch, .). These systems allow a service to be
28、 connected to a number of subscribers ranging from a few users to several hundred and over a wide range of distances. P-MP systems are generally, but not necessarily. configured as pre-assigned systems or as Demand Assigned Multiple Access (DAMA) radio systems. The essential features of a typical P-
29、MP DAMA radio systems are: - efficient use of the radio spectrum; - concentration; - transparency. Radio is often the ideal way of obtaining communications at low cost and almost independent of distance and difficult topology. Moreover, only a small number of sites are required for these installatio
30、ns, thus facilitating rapid implementation and minimizing maintenance requirements of the systems. Concentration means that N subscribers can share n channels (N being larger than n), allowing better use to be made of the available frequency spectrum and at a lower equipment cost. The term “multi-ac
31、cess“ is derived from the fact that every subscriber has access to every channel (instead of a fixed assignment 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. Concentrati
32、on requires the use of distributed intelligent control which in turn allows many other operation and maintenance functions to be added. Transparency means that the exchange and the telephone communicate with each other without being aware of the radio link. 6 ETSl EN 300 636 V1.3.1 (2001-02) 1 Scope
