The informationpertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be foundin SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in respectof ETSI standards", which is available free of charge from the ETSI Secretariat. Latest updates are available on theETSI Web server (http://www.etsi.org/ipr).Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guaranteecan be given as to the existence of other IPRs not referenced in SR 000 314 (or the updates on the ETSI Web server)which are, or may be, or may become, essential to the present document.ForewordThis European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmissionand Multiplexing (TM).The present document contains the minimum technical requirements to ensure compatibility of products andconformance with radio regulations across ETSI member states. Radio terminals from different manufacturers are notrequired to interwork at radio frequency (i.e. no common air interface). However, terminals may be combined with othermanufacturers' equipment on an Radio Frequency (RF) branching network for operation on different polarizations.The present document defines the requirements of radio terminal and radio relay equipment and associated interfaces.The requirements for multiplex, network management and antenna / feeder equipment may be addressed elsewhere.The present document was sent for ETSI Public Enquiry 67 as an ETS. To comply with the current ETSI deliverabletypes the present document has been converted to an EN.National transposition datesDate of adoption of this EN:22 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 1999SIST EN 300 430 V1.1.2:2003

ETSIEN 300 430 V1.1.2 (1999-02)61ScopeThe present document specifies parameters for digital radio-relay systems with a capacity of 1 x Synchronous TransportModule-1 (1 x STM-1) designed to operate in the 17,7 GHz to 19,7 GHz band. The channel spacing between adjacentco-polar channels is 55 MHz. Operation in the Co-Channel Dual Polarized (CCDP) mode with orthogonal polarizationsis also foreseen.The parameters to be specified fall into two categories:a)those that are required to provide compatibility between channels from different sources of equipment on thesame route connected either to:-separate antennas; or-separate polarizations of the same antenna; or-one polarization of one antenna at a frequency separation of twice the basic co-polar spacing (2 x 55 MHz),enabling interworking of different manufacturers equipment at the same Radio Frequency (RF) branching.This category also includes parameters providing compatibility with the existing radio-relay network;b)parameters defining the transmission quality of the proposed system.The standardization deals with Intermediate Frequency (IF), RF and baseband characteristics relevant to SynchronousDigital Hierarchy (SDH). Antenna / feeder system requirements are also considered.Two possible baseband interfaces have to be considered: one for STM-1 signals in accordance withITU-R Recommendation F.750 [4] and another for 140 Mbit/s signals.Safety aspects are outside the mandate of ETSI and they will not be considered in the present document.2ReferencesThe following documents contain provisions which, through reference in this text, constitute provisions of the presentdocument.· References are either specific (identified by date of publication, edition number, version number, etc.) ornon-specific.· For a specific reference, subsequent revisions do not apply.· For a non-specific reference, the latest version applies.· A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the samenumber.[1]ITU-R Recommendation F.595-5: "Radio-frequency channel arrangements for radio-relay systemsoperating in the 18 GHz frequency band".[2]ITU-R Recommendation F.634-4: "Error performance objectives for real digital radio-relay linksforming part of the high-grade portion of international digital connections at a bit rate below theprimary rate within an integrated services digital network".[3]ITU-R Recommendation F.695: "Availability objectives for real digital radio-relay links formingpart of a high-grade circuit within an integrated services digital network".[4]ITU-R Recommendation F.750: "Architectures and functional aspects of radio-relay systems forSDH-based networks".[5]ETS 300 019-1: "Equipment engineering; Environmental conditions & environmental tests fortelecommunications equipments, Part 1: Introduction and terminology".SIST EN 300 430 V1.1.2:2003
