21、hnical Specification (TS) was been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN) and originally published as ETSI ES 283 012 17. It was transferred to the 3rd Generation Partnership Project (3GPP) in in February
22、 2008. The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version
23、number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,
24、 updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. ETSI ETSI TS 129 412 V8.1.0 (2010-04)63GPP TS 29.412 version 8.1.0 Release 81 Scope The present document defines the control procedures for trunk gateways when PSTN/ISDN emulation and
25、PSTN/ISDN simulation services in an NGN Network require interworking with ETSI PSTN/ISDN services in a ISUP network. Interworking with BICC networks is not included in the scope of TISPAN R2. Existing profiles will be evaluated, in order to determine if they can be re-used, with possible modificatio
26、ns, or if a completely new profile is to be defined. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.)
27、or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies.

42、 The reference architecture applies to both PSTN/ISDN Simulation (IMS Architecture) and Emulation Subsystem (TISPAN PES). 4.2 Functional Requirements 1) Trunking Media Gateways shall support the establishment and release of IMS/NGN (ephemeral) Terminations. H.248 IMS/NGN Terminations are based on IP
43、. The IP version used by H248 IMS/NGN Terminations in TISPAN IMS domains is either IPv4 or IPv6.The default IP version is IPv4 for H.248 RTP Terminations for ETSI PES. IPv4 is still in use for H.248 IMS/NGN Terminations for VoIP NGNs, particularly in non-3GPP environments. NOTE: The default IP versi
44、on is IPv6 for H.248 IMS/NGN Terminations in 3GPP IMS domain. 2) Trunking Media Gateways shall support the establishment and release of TDM (physical) Terminations. 3) Trunking Media Gateways shall support the interworking of the associated User Plane (UP) protocol stacks for the networks to which t
45、he TMGW is inter-connecting. These details and further physical characteristics are described in clause 4.3. 4) Trunking Media Gateways shall provide support for G.711 A-law codecs and may support other codecs. 5) Trunking Media Gateways supporting other codecs than G.711 shall support autonomous tr
46、ansition to G.711-based VBD mode upon detection of voiceband data traffic (like fax/modem, data/modem, text/modem) according to V.152. This shall be upon a per-call-basis request from the MGC. Additionally, Trunking Media Gateways shall be fully compliant with ITU-T Recommendation G.168 6 on detecti
47、ng VBD. 6) Trunking Media Gateways supporting other codecs than G.711 shall also support the procedures defined in RFC 2833 5 to detect, generate and forward DTMF digits. DTMF shall be identified by name, as opposed to their waveform properties. ETSI ETSI TS 129 412 V8.1.0 (2010-04)93GPP TS 29.412 v

See also clauses 4.5.2.4 and 4.5.2.5. 8) All properties of tones requested by the MGC shall be provisioned in the Media Gateway. The MGC is not required to send the physical characteristics
49、of tones to Media Gateways. 9) Trunking Media Gateways shall support ISDN Bearer Service ITU-T Recommendation I.231.1 7 for TDM-to-TDM bearer connections. 10) Trunking Media Gateways shall support ISDN Bearer Service ITU-T Recommendation I.231.1 7 for TDM-to-RTP bearer interworking. This ISDN bearer service on TDM side shall be mapped onto RTP Clearmode according RFC 4040 8 on IP side. 11) Trunking Media Gateways shall support testing of circuit-oriented bearer connections at circuit-switched network interfaces of the
