ETSIETSI EN 301 401 V1.2.6 (1999-10)71ScopeThe present document specifies the technical characteristics to be provided by terminal equipment to be connected topublic networks presented at an ITU-T Recommendations V.10 [10], V.11 [11] (including X.26 [21] and X.27 [22]),V.12 [12], V.24 [13]/V.28 [14], V.35 [15] or V.36 [16] interface regardless of data rate. The objective of the presentdocument is to ensure that no disturbance occurs to the public network.The present document contains the minimum set of requirements derived from the above set of ITU-TRecommendations and is applicable for connection to X.21 [18] leased line and circuit switched, X.21 bis [19] leasedlines, X.25, Frame Relay and SMDS plus any other public network service that may be presented on the same electricalinterfaces.NOTE:Not all of the above services are available in all countries.A test is given for each requirement in the present document, including measurement methods. Requirements apply atthe public network interface of the terminal equipment, which may be stimulated to perform the tests by additionalequipment if necessary.Terminal equipment may be subject to additional or alternative requirements depending on its functionality, in particularif it supports a service that is considered to be a justified case for regulation of terminal interworking via thetelecommunications network.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]Council Directive 73/23/EEC of February 1973 on the harmonization of the laws of the MemberStates relating to electrical equipment designed for use within certain voltage limits (Low VoltageDirective.[2]Council Directive 89/336/EECof 3 May 1989 on the approximation of the laws of Member Statesrelating to electromagnetic compatibility.[3]Council Directive 98/13/EEC of 12 February 1998 relating to telecommunications terminalequipment and satellite earth station equipment, including the mutual recognition of theirconformity.[4]Council Directive 98/34/EC of 22 June 1998 laying down a procedure for the provision ofinformation in the field of technical standards and regulations.[5]ISO 2110 (1980): "Information technology - Data communication - 25-pole DTE/DCE interfaceconnector and contact number assignments".[6]ISO 2593 (1984): "Information technology - Telecommunications and information exchangebetween systems - 34-pole DTE/DCE interface connector and contact number assignments".[7]ISO 4902 (1980): "Information technology - Data communication - 37-pole DTE/DCE interfaceconnector and contact number assignments".SIST EN 301 401 V1.2.6:2004
