<strong>The</strong> <strong>Essential</strong> <strong>Report</strong> on IP TelephonyTIA TR-45.2: (PN-4934) to be published as TIA/EIA/IS-872, "IP Core Network-Legacy MS SupportDomain" and (PN-4935) to be published as TIA/EIA/IS-873, "IP Core Network-Multimedia Domain".TIA TR-45.3, "Time Division Digital Technology". An update of the TDMA Universal WirelessCommunications (UWC-136) technology has been completed and will be published as TIA/EIA-136-Rev C,"TDMA Third Generation [3G] Wireless". TR-45.3 worked with ETSI to design the UWC-136 RadioTransmission Technology (RTT) data section, General Packet Radio Service (GPRS) backbone for IP traffic,based on ETSI's GSM specifications.ETSI TIPHON: Communication between users connected to IP-based networks and Switched Circuit.IETF SPIRITS WG: PSTN/IN to the IP network and optional responses from the IP network back to thePSTN/IN.5aTraffic volumes (influence of IP traffic on fixed and mobile PSTN traffic), traffic engineeringand dimensioning of IP networksITU-T SG 2 WP 1 Q.2, "Routing and interworking plans for fixed and mobile networks".ITU-T SG 2 WP 3, "Traffic Engineering".IETF Internet Traffic Engineering (TEWG) WG.5bPending items at ITU-T (especially ITU-T IP Project)ITU-T SG 4 Q.10, "Framework for unified management of integrated circuit-switched andpacket-based networks (with initial emphasis on IP-based networks)".ITU-T SG 13 IP Project Description Version 5 (http://www.itu.int/ITU-T/studygroups/com13/ip/documents/IPProjectLastVersion5.doc).Scope of ITU-T IP Project: 1) IP Applications Including Multi media: Q.3/13, SG 10, SG 16. 2) ServiceInterworking: Qs 2/13, 5/13. 3) IP and non-IP Access: Qs 12/13, 14/13, SGs 15 and 16. 4) SignallingSupport: SG 11. 5) Network Capabilities: Qs 1, 2, and 3/13, SG 9. 6) Interworking: Q5/13, SG16 and SSG.7) IP Performance: Q 6/13, SGs 2 and 12. 8) IP Transport: Qs 10/13, 16/13, SG 15. 9) Management: SG 4,6/SSG, 4/15, 3/16. 10) Naming, Numbering, Addressing and Routing: SG 2. 11) Overall NetworkArchitecture and Framework: Qs 1, 11, 14 and 16/13. 12) Operational Issues: SGs 2, 3, and 7.ITU-T SG 13 List of Questions Under Study (http://www.itu.int/ITU-T/studygroups/com13/ questions.html).ITU-T SG 16 List of Questions under Study (http://www.itu.int/ITU-T/studygroups/com16/ questions.html).Organization of the IP-related ITU-T Recommendations Y.1000-series.IP-based Networks Contribution originating from SG 13, to the Secretary-General's <strong>Report</strong> to the ITUCouncil (http://www.itu.int/ITU-T/studygroups/com13/ip/documents/ip.doc).IETF WGs/ITU-T SGs Mapping (http://www.itu.int/ITU-T/studygroups/com13/ip/ietf-wg.html).130 Annex K
