ETSIEN 300 417-2-1 V1.1.2 (1998-11)81ScopeThe present document specifies a library of basic building blocks and a set of rules by which they are combined in orderto describe transport functionality of equipment. The library comprises the functional building blocks needed tocompletely specify the generic functional structure of the European transmission hierarchies. Equipment which iscompliant with the present document needs to be describable as an interconnection of a subset of these functional blockscontained within the present document. The interconnections of these blocks need to obey the combination rules given.The generic functionality is described in the EN 300 417-1-1 [8].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]ANSI T1.102 (1993): "Telecommunications; Digital Hierarchy; Electrical Interfaces".[2]ANSI T1.107 (1988): "Telecommunications; Digital Hierarchy; Formats Specifications".[3]ETS 300 147: "Transmission and Multiplexing (TM); Synchronous Digital Hierarchy (SDH);Multiplexing structure".[4]ETS 300 166 (1993): "Transmission and Multiplexing (TM); Physical and electrical characteristicsof hierarchical digital interfaces for equipment using the 2 048 kbit/s - based plesiochronous orsynchronous digital hierarchies".[5]ETS 300 167: "Transmission and Multiplexing (TM); Functional characteristics of 2 048 kbit/sinterfaces".[6]ETS 300 232 (1993): "Transmission and Multiplexing (TM); Optical interfaces for equipments andsystems relating to the Synchronous Digital Hierarchy [ITU-T Recommendation G.957 (1993)modified]".[7]ETS 300 337: "Transmission and Multiplexing (TM); Generic frame structures for the transport ofvarious signals (including Asynchronous Transfer Mode (ATM) cells and Synchronous DigitalHierarchy (SDH) elements) at the ITU-T Recommendation G.702 hierarchical rates of 2 048kbit/s, 34 368 kbit/s and 139 264 kbit/s".[8]EN 300 417-1-1: "Transmission and Multiplexing (TM); Generic requirements of transportfunctionality of equipment; Part 1-1: Generic processes and performance".[9]EN 300 417–6–1: "Transmission and Multiplexing (TM); Generic requirements of transportfunctionality of equipment; Part 6-1: Synchronization distribution layer functions".[10]CCITT Recommendation G.703 (1991): "Physical/electrical characteristics of hierarchical digitalinterfaces".[11]CCITT Recommendation G.742 (1988): "Second order digital multiplex equipment operating at8 448 kbit/s and using positive justification".SIST EN 300 417-2-1 V1.1.2:2003
