Page 7ETS 300 630: March 19971ScopeThis ETS specifies the minimum performance parameters for terrestrial digital fixed service radiocommunications equipment operating in the 1,4 GHz frequency bands. The requirements and limits givenin this ETS are relevant to all environmental conditions for the chosen climatic class. The test methods tobe used are currently under study in ETSI STC TM4.Digital systems are intended to be used for point-to-point connections in local and regional networks atdata rates between 9,6 kbit/s and 4x2 Mbit/s. Other data rates may also be foreseen. Typical applicationsinclude:a)customer connections;b)Integrated Services Digital Network (ISDN) extension;c)mobile base station connections;d)telemetry and telecontrol, including transportable and off-shore use.CCIR high, medium and local grade performance objectives, i.e. CCIR Recommendations F.634 [14],F.696 [4], F.697 [5], CCITT Recommendation G.821 [7] and the forthcoming performance objectivesdetailed in ITU-T Recommendation G.826 [8] should be realizable using systems considered in this ETS.The parameters to be specified fall into two categories:a)Those that are required to provide compatibility between channels from different sources ofequipment on the same route, connected either to:-separate antennas; or to-separate polarizations of the same antenna.b)Parameters defining the transmission quality of the proposed system.The ETS deals with Intermediate Frequency (IF), Radio Frequency (RF) and baseband characteristicsrelevant to low capacity Plesiochronous Digital Hierarchy (PDH) transmission. Antenna/feeder systemrequirements are covered in EN 300 631 [12].Due to the wide spread of applications and corresponding system rates, parameters such as RF spectrummasks and receiver sensitivity are related to standardized channel spacings rather than to minimumsystem rates. This allows individual countries to allocate a bandwidth and therefore a standard channelspacing in accordance with the foreseen services and their own frequency management and radionetwork planning.As the maximum bit rate in a given bandwidth depends on the system spectral efficiency, differentequipment classes are defined:Class 1:equipment based on a minimum of 2-level modulation scheme (e.g. 2-FSK,GMSK with discriminator detection, or equivalent);Class 2:equipment based on a minimum 4-level modulation scheme (e.g. 4-FSK,4-QAM, or equivalent);Class 3:equipment based on a minimum 16-level modulation scheme (e.g. 16-QAM, orequivalent).Safety aspects are outside the mandate of ETSI and they will not be considered in this ETS.SIST ETS 300 630 E1:2003
