Page 7ETS 300 011 : April 1992ForewordThis European Telecommunication Standard (ETS) was produced by the Transmission and Multiplexing(TM) Technical Committee of the European Telecommunications Standards Institute (ETSI).This ETS aims to meet urgent requirements of network operators and equipment manufacturers who aredesigning equipment to operate with an Integrated Services Digital Network (ISDN) primary rate accessuser-network interface. This ETS shall replace CEPT Recommendation T/L 03-14 (November 1987).This ETS is based upon CCITT Recommendation I.431 (1988) [9] and provides modifications and furtherrequirements to that base document. It also is affected by CCITT Recommendations G.703 [2], G.704 [3]and G.706 [4] (1988), and modifications and statements to these CCITT Recommendations are providedwithin this ETS.This ETS also takes into account requirements contained in ECMA Standard 104: "Physical layer at theprimary rate access interface between data processing equipment and private switching networks (1985)",which are given in Annex B.SIST ETS 300 011 E1:2003

Page 9ETS 300 011 : April 19921ScopeThis European Telecommunication Standard (ETS) specifies requirements and test principles for the ISDN72048 kbit/s primary rate user-network interface including the physical, electrical and functionalcharacteristics and the information exchange with higher layers. Compliance with this ETS ensures that,with regard to layer 1 interface aspects, equipment for use with ISDN primary rate access is portablewithin countries that adhere to this ETS and, furthermore, that interworking with higher layer protocols forISDN is supported.This ETS is applicable to equipment having interface Ia or Ib for the connection to the ISDN primary rateuser-network interface intended to be installed on customers' premises. In accordance with CCITTRecommendation I.411 [10], this ETS is to be applied to interfaces at reference points S, T and S/T(coincident S and T) of the ISDN reference configuration.This ETS is applicable for ISDN channel arrangements as defined in CCITT Recommendation I.412 [11],as far as the primary rate at 2048 kbit/s is concerned.This ETS is based on CCITT Recommendation I.431 [9] and gives further requirements or modifications tothat Recommendation. Furthermore, this ETS identifies for each clause of CCITT Recommendation I.431[9] whether it is regarded as normative, informative or as not relevant in the sense of an ETS.This ETS also specifies, in Annex A, reference configurations and special requirements for application ofthis interface as a user-network interface for leased lines or as a user-user interface in particular forPrivate Telecommunications Network Exchange (PTNX) interconnections.Annex B specifies additional requirements for interfaces at reference point S.Annex C to this ETS specifies the relevant test principles to verify the requirements, and for testingconformance to this ETS. It is outside the scope of this ETS to define the static conformance requirementsan equipment has to meet for attachment approval to a public network.This ETS does not specify:-safety requirements;-interface or equipment overvoltage protection requirements;-immunity requirements against electromagnetic interferences;-emission limitation requirements.2Normative referencesThis ETS incorporates, by dated or undated reference, provisions from other publications. These normativereferences are cited at the appropriate places in the text and the publications are listed hereafter. Fordated references subsequent amendments to, or revisions of, any of these publications apply to this ETSonly when incorporated in it by amendments or revision.

Page 11ETS 300 011 : April 19923DefinitionsFor the purpose of this ETS the following definitions, together with those given in Clause 3 of ETS 300 012[1] and in CCITT Recommendation I.411 [10] apply. Further definitions are given in Annex B.Terminal equipment (TE): an equipment providing an interface Ia.NOTE:This term is used in this ETS to indicate terminal-terminating aspects of TE1, TA andNT2 functional groups, where these have an Ia interface.Terminal equipment type 1 (TE1): this functional group includes functions belonging to the functionalgroup TE, and with an interface that complies with the ISDN user-network interface standard.Network termination (NT): an equipment providing interface IbNOTE:This term is used in this ETS to indicate network-terminating aspects of NT1 and NT2functional groups where these have an Ib interface.Network termination type 1 (NT1): this functional group includes functions broadly equivalent to layer 1(physical) of the OSI reference model. These functions are associated with the proper physical andelectromagnetic termination of the network. NT1 functions are:-Line transmission termination;-layer 1 maintenance functions and performance monitoring;-timing;-layer 1 multiplexing;-interface termination.Network termination type 2 (NT2): this functional group includes functions broadly equivalent to layer 1and higher layers of the CCITT Recommendation X.200 reference model. Private Automatic BranchExchanges (PABXs), local area networks and terminal controllers are examples of equipment orcombinations of equipment that provide NT2 functions. NT2 functions include:-layer 2 and 3 protocol handling;-layer 2 and 3 multiplexing;-switching;-concentration;-maintenance functions;-interface termination and other layer 1 functions.Terminal adapter (TA): an equipment with interface Ia and one or more auxiliary interfaces that allow non-ISDN terminals to be served by an ISDN user-network interface.Interface Ia: user side of the ISDN user-network interface for the primary rate access.Interface Ib: network side of the ISDN user-network interface for the primary rate access.SIST ETS 300 011 E1:2003
