22、 Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). ETSI ETSI TR 183 014 V1.1.1 (2005-12) 6 1 Scope The present document presents the results of an analysis of bearer, ba

23、sic and supplementary services currently provided in PSTN and ISDN implementations. The purpose of the analysis was to identify further areas of standardization to ensure that such services can be reliably emulated within the NGN thus enabling network operators to fulfil the technical regulatory obl

24、igations on European ECN providers of Publicly Available Telephone Service. It was assumed during the analysis that PSTN and ISDN signalling would be presented in the Integrated Services User Part (ISUP) as defined in EN 300 356-1 3 and EN 300 356-2 4 and that signalling within the NGN would be enca

25、psulated in SIP-I as defined in EN 383 0011 and ITU-T Recommendation H.248.1 29. 2 References For the purposes of this Technical Report (TR), the following references apply: 1 ETSI EN 383 001: “Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN); Interwo
