Foreword This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document contains the m
25、inimum technical requirements to ensure compatibility of products and conformance with radio regulations across ETSI member states. Radio terminals from different manufacturers are not required to interwork at radio frequency (i.e. no common air interface). The present document defines the requireme
26、nts of radio terminal and radio-relay equipment and associated interfaces. The requirements for multiplex, network management and antenna 1 feeder equipment may be addressed elsewhere. The former title of the present document was: “Transmission and Multiplexing (TM); Digital Radio Relay Systems (DRR
27、S); Sub-STM- 1 DRRS operating in the 13 GHz, 15 GHz and 18 GHz frequency bands with about 14 MHz co-polar channel spacing“. National transposition dates Date of adoption of this EN: 9 February 200 1 Date of latest announcement of this EN (doa): 31 May 2001 Date of latest publication of new National
28、Standard or endorsement of this EN (dopie): 30 November 2001 Date of withdrawal of any conflicting National Standard (dow): 30 November 200 1 6 ETSI EN 300 786 V1.3.1 (2001-02) Scope The present document specifies the minimum performance parameters for terrestrial fixed services radiocommunications
29、equipment, as given below, for operation in the 13 GHz (12,75 GHz to 13,25 GHz), 15 GHz (14,5 GHz to 15,35 GHz) and 18 GHz (17,7 GHz to 19,7 GHz) frequency bands. The present document covers equipment for the transmission of sub-STM-1 digital signals with a VC3 payload capacity. The standardization
30、of sub-STM-1 radio systems 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 application of these digital radio-relay systems is anticipated to be for poin
31、t-to-point links in local, regional and national networks, mobile base station connections, customer and access links. Consideration has to be given to special requirements of the local and access network, e.g. simple towers with less space for antenna, different network structures with high density
32、 nodes. The systems considered shall operate in these networks having regard for existing hop lengths, which mainly depend on the frequency band envisaged, the performance objectives set by relevant ITU-R Recommendations or national Network Operators requirements and existing propagation characteris
33、tics. The hop lengths are considered to be normally up to 37 km in the 13 GHz band, up to 30km in the 15 GHz band and up to 20 km in the 18 GHz band. The parameters to be specified fall into two categories: a) Those that are required to provide compatibility between RF channels occupied by different
34、 sources of equipment on the same route connected either to: - separate antennas; or to - separate polarization of the same antenna. NOTE: Equipment supplied by different manufactures on the same path and using different polarizations shall operate on different frequencies. b) Parameters defining th
35、e transmission quality of the proposed system. The standardization deals with IF, RF and baseband characteristics relevant to Sub-STM-1 SDH transmission. Spurious emissions and EMC requirements are also included in the present document. Safety regulations are outside the scope of the present documen
