Page 5ETR 189: June 1995ForewordThis ETSI Technical Report (ETR) has been produced by the Signalling Protocols and Switching (SPS)Technical Committee of the European Telecommunications Standards Institute (ETSI).ETRs are informative documents resulting from ETSI studies which are not appropriate for EuropeanTelecommunication Standard (ETS) or Interim European Telecommunication Standard (I-ETS) status. AnETR may be used to publish material which is either of an informative nature, relating to the use or theapplication of ETSs or I-ETSs, or which is immature and not yet suitable for formal adoption as an ETS oran I-ETS.PSIST ETR 189:1996

Page 7ETR 189: June 19951ScopeThis ETSI Technical Report (ETR) provides an overview of the codepoints used by the Digital SubscriberSignalling System No. one (DSS1) protocol for the pan-European Integrated Services Digital Network(ISDN) as provided by European public telecommunications operators at the T reference point orcoincident S and T reference point (as defined in ITU-T Recommendation I.411 [3]).This overview is related to messages, information elements, notification indicator values, progressindicator values, state values, operation and error values which are used for basic call, packet mode call,and supplementary services specified so far by ETSI. In addition, the operations and errors identified byan ETSI object identifier is included in a separate table.All codepoints currently specified either by ETSI or ITU-T are shown in the following tables. When acodepoint is specified for use in networks conforming to an ETSI standard, a reference is included in thetable to indicate the ETS where the particular codepoint is defined.Other codepoint values are indicated by the note: "Not applicable in networks conforming to ETSIstandards". This note applies to values which are used in ITU-T Recommendations, but are not currentlyspecified for use by ETSI in any ETS.Clause 12 of this ETR shows the relationship between messages and the information elements that eachmessage may carry. The purpose of tables 12 to 15 is only to provide an overview of possible messagecontents but it does not indicate which information element or combinations of information elements arepresent in a particular message for a specific purpose (e.g. basic call, a certain supplementary service).2ReferencesThis ETR incorporates by dated or undated reference, provisions from other publications. Thesereferences 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 ETRonly when incorporated in it by amendment or revision.
