Radio terminals from different manufacturers are notrequired to inter work at radio frequency (i.e. no common air interface).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 documentdifferent sets of system parameters. In the present document these set of parameters are referred to as "system types".National transposition datesDate of adoption of this EN:1 January 1999Date of latest announcement of this EN (doa):30 April 1999Date of latest publication of new National Standardor endorsement of this EN (dop/e):31 October 1999Date of withdrawal of any conflicting National Standard (dow):31 October 1999IntroductionThe main field of application of Point-to-Multipoint (P-MP) systems, using the Fixed Service (FS), is to provide accessto both public and private networks (Public Switched Telephone Network (PSTN), Public Data Network (PDN), etc.).By means of P-MP systems the network service area may cover scattered subscriber locations. The systems may beapplied to build new access networks by means of a multi cellular architecture, covering both urban and regional areas.Subscribers are offered the full range of services by the particular public or private network. Subscribers have access tothese services by means of the various standardized user network interfaces (e.g. 2-wire loop, and Integrated ServicesDigital Network (ISDN) ranging from basic rate to n × primary rate).P-MP systems provide standard network interfaces and transparently connect subscribers to the appropriate networknode. These systems allow a service to be connected to a number of subscribers ranging from a few to several thousand,and over a wide range of distances.P-MP systems are generally configured as pre-assigned systems or as Demand Assigned Multiple Access (DAMA) radiosystems.SIST EN 301 080 V1.1.1:2003
ETSIEN 301 080 V1.1.1 (1999-02)6The essential features of a typical P-MP radio system 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 difficulttopography. Moreover, a small number of sites are required for these installations, thus facilitating rapid implementationand minimizing maintenance requirements of the systems.Concentration means that m subscribers can share n radio channels (m being larger than n), allowing a better use of theavailable frequency spectrum at a lower equipment costs. The term "multi-access" means that every subscriber hasaccess to every channel (instead of a fixed assignment as in most multiplex systems). When a call is initiated, anavailable channel 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 andmaintenance functions to be added.Transparency means that the network node (service node) and the subscriber equipment communicates with each otherwithout being aware of the radio link.SIST EN 301 080 V1.1.1:2003
ETSIEN 301 080 V1.1.1 (1999-02)71ScopeThe present document specifies the minimum requirements for system parameters of Frequency Division MultipleAccess (FDMA) Point-to-Multipoint (P-MP) radio systems in the terrestrial Fixed Service (FS) operating in the bands3 GHz to 11 GHz.The system will provide access to both public and private networks (Public Switched Telephone Network (PSTN),Public Data Network (PDN), etc.) by means of the various standardized network interfaces (e.g. 2-wire loop, IntegratedServices Digital Network (ISDN) and 2 Mbit/s).The system may be applied to build access networks by means of a multi cellular architecture, covering urban, includingsuburban, and regional areas.The FDMA P-MP system will transmit a Radio Frequency (RF) signal from the customer site to the Central Station (CS)only utilizing a spectral bandwidth corresponding to that capacity which is requested from and assigned to the customerby pre-assignment or by Demand Assigned Multiple Access (DAMA). The CS receives from each customer site a singlemodulated carrier being processed independently within the CS. Thus the CS is receiving a FDMA signal.The present document covers the following typical P-MP applications:The transmission of:-voice;-fax;-voice band data;-telex;related to analogue interfaces and:-64 Kbit/s;-ISDN;-digital video;-digital audio;related to digital interfaces.Further applications like Asynchronous Transport Mode (ATM) may also be provided.Two classes of systems have been defined in order to take into account the large variety of possible applications due toaccess network implementations and type of service to be provided.The equipment covered by the present document should be designed to be able to meet the network performancerequirements foreseen by ITU-R Recommendations F.696-2 [1] and F.697-2 [2], for medium, local grade orITU-R Recommendation F.1189-1 [3] national portion (access or short haul) of the digital connection following thecriteria defined in ITU-T Recommendation(s) G.821 [4] and/or G.826 [5]. It should be noted that the values for B and Care provisional taking also into account note 5 of ITU-R Recommendation F.1189-1 [3].The availability requirements are under further study by the relevant bodies.Network operators may choose different performance and availability requirements in order to extend the possible areaof application thus fitting to their network needs.Radio terminals from different manufacturers are not intended to interwork at radio frequency (i.e. no common airinterface).The present document defines the requirements of radio terminal and radio-relay equipment including the interfaces.The requirements for multiplex, network management and antenna / feeder equipment may be addressed elsewhere.SIST EN 301 080 V1.1.1:2003
