ETSIEN 301 163-1-1 V1.1.1 (1999-05)71ScopeThe purpose of the present document is to provide specifications for ATM equipment to be used in the ETSI region.These specifications seek to define the processes associated with ATM rather than specific equipment types. Suchspecifications will ensure compatibility between equipment by identifying which functions within a process aremandatory for interworking and which can be considered as truly optional. It is not the intention to preventmanufacturers or procurers from following an alternative specification, but the consequences should become clear fromthe present document.The ETSI ATM Equipment specification will be in two parts. The first part (the present document) being moreconceptual, producing a list of functions and processes and some guidance to the ITU model and the ETSI functionalmodel. The second part (EN 301 163-2-1 [18]) is a formal representation of transfer and layer management functions inthe form of a library of atomic functions. This will provide flexibility since many equipment types may be defined byusing these atomic functions in different combinations.The specification will take advantage of the work done in ITU but will take the work further with an ETSI view. Thismeans: the identification of ITU options that has to be mandatory in the ETSI region, deletion of options not requiredfor the ETSI region, creation of new or revised descriptions where necessary, identification of guideline or benchmarkperformance parameters for classes of equipment.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]ATMF TM v4.0: "Integrated Local Management Interface (ILMI) Specification v4.0".[2]ETS 300 019-1-0: "Equipment Engineering (EE); Environmental conditions and environmentaltests for telecommunications equipment; Part 1-0: Classification of environmental conditions;Introduction".[3]ETS 300 119-1: "Equipment Engineering (EE); European telecommunication standard forequipment practice; Part 1: Introduction and terminology".[4]ETS 300 132-1: "Equipment Engineering (EE); Power supply interface at the input totelecommunications equipment; Part 1: Operated by alternating current (ac) derived from directcurrent (dc) sources".[5]ETS 300 132-2: "Equipment Engineering (EE); Power supply interface at the input totelecommunications equipment; Part 2: Operated by direct current (dc)".[6]ETS 300 150: "Transmission and Multiplexing (TM); Protocol suites for Q interfaces formanagement of transmission systems".[7]ETS 300 253: "Equipment Engineering (EE); Earthing and bonding of telecommunicationequipment in telecommunication centres".[8]ETS 300 301: "Broadband Integrated Services Digital Network (B-ISDN); Traffic control andcongestion control in B-ISDN".SIST EN 301 163-1-1 V1.1.1:2003
