16、p (SMG Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI). This ETS identifies the Interworking Functions (IWFsI and requirements to support interworking between Public Land Mobile Network (PLMN) and Circuit Switched Public Data Network (CCPDN). This final draft E
17、TS corresponds to GSM technical specification GSM 09.04 version 4.0.2. The specification from which this ETS has been derived was originally based on CEPT documentation, hence the presentation of this final draft ETS may not be entirely in accordance with the ETSVPNE rules. Reference is made within
18、this final draft ETS to GSM-TSs. NOTE: TC-SMG has produced documents which give the technical specifications for the implementation of the European digital cellular telecommunications system. Historically, these documents have been identified as GSM Technical Specifications (GSM-TSs). These TSs may
19、have subsequently become I-ETSs (Phase 11, or ETSs (Phase 21, whilst others may become ETSI Technical Reports (ETRs). GSM-TSs are, for editorial reasons, still referred to in GSM ETSs.
