NOTE: En a previous version (ETS 300 43 1 i47), there was provisioa for: - further options for Grade A digital radao sysiems (wth i 12 MHz charnel separation); - specfic antenna radiataon patterns (now saperseded by EN 400 843 4) These optlons are not reprinted an the present document as the
21、y are considered to be no longer of anterest for ETSi members However, for regulatory purposes, they may stall be referenced from ETS 300 431 1371 Digital systems are intended to be used for point-to-point connections in local and regionai networks at data rates between 2 Mbitls and the Synchronous
22、Transport Module, Level I (STM-1). The parameters to be specified fall into two categories: a) those that are reqmred to provide compatibility between channels from different sources of equipment on the same route, connected either: - to separate antennas; or - to separate polarizations of the same
23、antenna. b) parameters defining the transmission quality of the proposed system. The present document deals with Radio Frequency (RF) and baseband characteristics relevant to low, medium and high capacity Plesiochronous Digital Hierarchy (PDH) transmission systems, STM-0 and STM-1 Synchronous Digita
24、l Hierarchy (SDH) transmission systems. Antennalfeeder system requirements are covered in EN 300 833 3. For digital systems, with capacities up to 34 Mbitls, for class 2 equipment there are also two types of equipment specified: - grade A equipment, intended for applications where moderate frequency
25、 congestion is envisaged; - the deployment of grade A equipment in new links will be limited and stopped over a period of time. Therefore, it is likely that provision for grade A equipment will be removed from the present document during the next revision: - grade B equipment, intended for applicati
26、ons where higher nodal capacity is required. The present document does not contain aspects related to test procedures and test conditions, however they are to be found in EN 30 1 126- 1 2. As the maximum transmission rate in a given bandwidth depends on system spectral efficiency, different equipmen
27、t classes are defined: class 2: equipinent spectral efficiency based on typically 4-states modulation scheme (e.g. 4-FSHC, 4-QM, or equivalent); class 3: equipment spectral efficiency based on typically 8-states modulation scheme (e.g. 8PSK, or equivalent); class 4: equipment spectral efficiency bas
28、ed on typically 16 or 32-states modulation scheme (e.g. 16-QM, 32-QM, or equivalent); class 5: equipment spectral efficiency based on typically 64 or 128-states modulation scheme (e.g. 64-QW, 128-QN, or equivalent). The above classes are indicatnve only and do not imply any csnstra-int to the actual
29、 modulation format, provided that all the requirements in the present document are met. Safety aspects will not be considered in the present document. However compliance to EN 40950 1351 will be required to comply with Directive 199915lEC 36 (R Conformance testing; Part 1: Point-to-point equipment -
