Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document contains the minimum technical requirements to ensure compatibilit
26、y of products and conformance with radio regulations across the European states of interest to ETSI Member. Radio terminals from different manufacturers are not required to interwork at radio frequency (i.e. no common air interface). The present document defines the requirements of radio terminal an
27、d radio relay equipment and associated interfaces. The requirements for multiplex, network management and antennalfeeder equipment may be addressed elsewhere. The former title of the present document was: “Transmission and Multiplexing (TM); Sub-STM1 Digital Radio Relay Systems (DRRS) operating in t
28、he 13 GHz, 15 GHz and 18 GHz frequency bands with about 28 MHz co-polar and 14 MHz cross-polar channel spacing“. National transposition dates Date of adoption of this EN: 16 February 2001 Date of latest announcement of this EN (doa): 31 May 2001 Date of latest publication of new National Standard or
29、 endorsement of this EN (dople): 30 November 200 1 Date of withdrawal of any conflicting National Standard (dow): 30 November 200 1 1 Scope The present document specifies the minimum performance parameters for terrestrial fixed services radio communications equipment, as given below, for operation i
30、n the 13 GHz, 15 GHz and 18 GHz frequency bands (i.e. 12,75 GHz to 13,25 GHz, 14,50 GHz to 15,351 GHz and 17,70 GHz to 19,70 GHz). The equipments covered by the present document are intended for operation with about 28 MHz basic channel spacing with frequency re-use either in 14 MHz interleaved mode
31、 or in co-channel mode (definitions are in ITU-R Recommendation F.746-4 26). The present document covers equipment for the transmission of sub-Synchronous Transport Module level-1 (STM-I) digital signals with a Virtual Container-3 (VC-3) payload capacity. The standardization of sub-STM-1 radio syste
32、ms for 13 GHz, 15 GHz and 18 GHz bands has been prepared to ensure the compatibility with the existing plesiochronous and the new synchronous systems concerning frequency plans and performance. The architecture and functional aspects should be in accordance with ITU-R Recommendation F.750-3 7 and tr
33、ansmission characteristics and performance requirements in accordance with ITU-R Recommendation F.75 1-2 8. The present document does not cover aspects related to test procedures and test conditions which are currently under study in TM4. The application of these Digital Radio Relay Systems (DRRS) i
34、s anticipated to be for point-to-point links in local, regional and national networks, mobile base station connections and customer access links. Consideration has to be given to special requirements of the local network (e.g. simple towers with less space for antenna, different network structures w
35、ith high density nodes). The systems considered in the present document are intended to operate on average hop lengths about 15 km for 1 8 GHz band, 20 km for 15 GHz band and 30 krn for 13 GHz band. Equipment should be designed in order to meet network performance and availability requirements defin
36、ed by ITU-T Recommendations G.82 1 17 and G.826 IS, following the criteria defined in ITU-RRecommendations F.634-4 3, F.695 30, F.696-2 5, F.697-2 6, F.1092-1 28 and F.1189-1 29, for high or medium or local grade or the international or the national portion of the digital connection. The parameters
37、to be specified fall into two categories: a) those that are required to provide compatibility between Radio Frequency (RF) channels occupied by different sources of equipment on the same route connected either: - to separate antennas; or - to separate polarization of the same antenna. b) parameters
38、defining the transmission quality of the proposed system. The standardization deals with Intermediate Frequency (IF), RF and baseband characteristics relevant to sub-STM-1 Synchronous Digital Hierarchy (SDH) transmission. Spurious emissions and ElectroMagnetic Compatibility (EMC) requirements are al
39、so included in the present document.
