Page 11ETS 300 417-3-2: November 1997ForewordThis European Telecommunication Standard (ETS) has been produced by the Transmission andMultiplexing (TM) Technical Committee of the European Telecommunications Standards Institute (ETSI).This ETS provides the Implementation Conformance Statement (ICS) proforma specification to be used inconnection with conformance/approval testing of Synchronous Digital Hierarchy (SDH) equipment. It isone of a family of ETSs covering various aspects of SDH equipment standards.The ICS proforma specification will ultimately consist of 8 sub-parts of ETS 300 417, numbered 1-2 to 8-2,each of which will correspond to sub-parts 1-1 to 8-1 of ETS 300 417, respectively. The ICS sub-parts are:Part 1-2:ETS 300 417-1-2: "General information about Implementation Conformance Statement (ICS) proforma specification";Part 2-2:ETS 300 417-2-2: "SDH and PDH Physical section layer functions Implementation Conformance Statement (ICS) proforma specification";Part 3-2:ETS 300 417-3-2: "STM-N regenerator and multiplex section layer functions Implementation Conformance Statement (ICS) proforma specification";Part 4-2:ETS 300 417-4-2: "SDH path layer functions Implementation Conformance Statement (ICS) proforma specification";Part 5-2:ETS 300 417-5-2: "PDH path layer functions Implementation Conformance Statement (ICS) proforma specification";Part 6-2:ETS 300 417-6-2: "Synchronization layer functions Implementation Conformance Statement (ICS) proforma specification";Part 7-2:ETS 300 417-7-2: "Auxiliary layer functions Implementation Conformance Statement (ICS) proforma specification";Part 8-2:ETS 300 417-8-2: "Major compound functions, Implementation Conformance Statement (ICS) proforma specification".Transposition datesDate of adoption:24 October 1997Date of latest announcement of this ETS (doa):28 February 1998Date of latest publication of new National Standardor endorsement of this ETS (dop/e):31 August 1998Date of withdrawal of any conflicting National Standard (dow):31 August 1998SIST ETS 300 417-3-2 E1:2003

Page 12ETS 300 417-3-2: November 1997IntroductionTo evaluate conformance of a particular implementation, it is necessary to have a statement of whichcapabilities and options have been implemented for a telecommunication specification. Such a statementis called an Implementation Conformance Statement (ICS).A client of a test laboratory who requests a conformance/approval test shall provide to the test laboratorya completed ICS proforma for each layer to be tested and a detailed system description of theimplementation.The ICS proforma is not another complete description of the related specification, but rather a compactform of its static conformance requirements, to be used by the test laboratory to identify which test shallbe performed on a given implementation. Not every feature of a profile specification is contained in therelated ICS proforma. For particular cases requiring specific information the ICS can refer to theappropriate clause of the related specification by means of references, notes and or comments.The ICS proforma captures the implementation flexibility allowed by the related specification and detailswhich option are left to the implementor, which are conditionally dependent on other
