Page 7ETS 300 417-1-1: January 1996ForewordThis European Telecommunication Standard (ETS) has been produced by the Transmission andMultiplexing (TM) Technical Committee of the European Telecommunications Standards Institute (ETSI).This ETS has been produced in order to provide inter-vendor and inter-operator compatibility ofSynchronous Digital Hierarchy (SDH) equipment.This ETS consists of 8 parts as follows:Part 1:"Generic processes and performance" (DE/TM-01015-1-1).Part 2:"Physical section layer functions" (DE/TM-01015-2-1).Part 3:"STM-N regenerator and multiplex section layer functions" (DE/TM-01015-3-1).Part 4:"SDH path layer functions" (DE/TM-01015-4-1).Part 5:"PDH path layer functions" (DE/TM-01015-5-1).Part 6:"Synchronization distribution layer functions" (DE/TM-01015-6-1).Part 7:"Auxiliary layer functions" (DE/TM-01015-7-1).Part 8:"Major compound functions" (DE/TM-01015-8-1).Parts 2 to 7 specify the layers and their atomic functions. Part 8 specifies combinations of atomicfunctions, the compound and major compound functions.NOTE 1:This ETS does not currently address configuration management.NOTE 2:The SDH radio equipment functional blocks are addressed by ETSI STC TM4.Transposition datesDate of adoption of this ETS:31 January 1996Date of latest announcement of this ETS (doa):30 April 1996Date of latest publication of new National Standardor endorsement of this ETS (dop/e):31 October 1996Date of withdrawal of any conflicting National Standard (dow):31 October 1996SIST ETS 300 417-1-1 E1:2003

Page 9ETS 300 417-1-1: January 19961ScopeThis European Telecommunication Standard (ETS) specifies a library of basic building blocks and a set ofrules by which they may be combined in order to describe a digital transmission equipment. The librarycomprises the functional building blocks needed to specify completely the generic functional structure ofthe European digital transmission hierarchy. In order to be compliant with this ETS, equipment needs tobe describable as an interconnection of a subset of these functional blocks contained within this ETS. Theinterconnections of these blocks should obey the combination rules given.This ETS specifies both the components and the methodology that should be used in order to specifySDH equipment; it does not specify an individual SDH equipment as such.The specification method is based on functional decomposition of the equipment into atomic, compoundand major compound functions. The equipment is then described by its Equipment FunctionalSpecification (EFS) which lists the constituent atomic and compound functions, their interconnection, andany overall performance objectives (e.g. transfer delay, availability, etc.). The concept is illustrated infigure 1.The internal structure of the implementation of this functionality (equipment design) need not be identicalto the structure of the functional model, as long as all the details of the externally observable behaviourcomply with the EFS.The equipment functionality is consistent with the SDH multiplexing structure given in ETS 300 147 [1].Equipment developed prior to the production of this ETS may not comply in all details with this ETS.Equipment which is normally stated to be compliant with this ETS may not fulfil all the requirements in thecase that it is interworking with old equipment that is not compliant with this ETS.The structure of the ETS envisages the addition of new layers, atomic functions and (major) compoundfunctions. For example, Asynchronous Transfer Mode (ATM), Integrated Services Digital Network (ISDN)and n x 64 kbit/s layers could be added as new complete parts while corresponding adaptation functionsare added to existing layers. "SDH interworking" functionality can be added as new layers in part 5. Thisapproach allows for short development times for standards describing new functionality.Atomicfunction XPerformanceobjectives listPerformanceobjectives listPerformanceobjectives listPerformanceobjectives listAtomicfunction YAtomicfunction ZEquipmentfunctionalspecificationOverall performanceobjectives listCompoundfunction 1Inter-connectFigure 1: Composition of equipment functional specificationSIST ETS 300 417-1-1 E1:2003
