  1. Liaison Report of N2171 Jihyun Lee 2013. 12. 13 1

  2. Content Scope of N2171 ANT(Access Network Transport) Reference Model ANT Interface and Scenarios ANT-Relevant Standards of SC25 WG1 Appendix 2

  3. Scope of N2171 • Scope • defines an ANT(Access Network Transport) on the background of the Recs. G.902 and GII Y.100 series • provides an overview of the existing ANT related standards released and/or prepared by the ITU and other standardization bodies. • Main purpose • Which standards exist • Topics/standards under study/development • Lack of standards • Duplication and/or overlap • Market needs • Priorities 3

  4. ANT Reference Model 4 • Logical represen

  5. ANT Interface • SNISn : between Service Function and Access Network (n- seq. number) • SNICn : between Core Network and Access Network ( n- seq. number) • XNIXYn : between Access Network and CPN (x: type of access technology / y: medium) • Ln : between Access Networks • Qn : between Access Network and Management Agent/Network 5

  6. ANT Scenarios 6

  7. Sample format for standards matrix Classification: G= General; O= Overview; A= Architecture; Q= Network Management Access Medium: F= Fiber; C= COAX; P= Twisted pair; A= Wireless Interface: J= User/Access Network; H= Service Node/Access Network; B= Direct Server/Access Network; W= User/Wireless Access Network The matrix will be updated through liaison to ITU-T, ITU-R, and standards organizations outside the ITU. It is planned to eventually replace this manual method for presenting the matrix of standards with a web-based approach. 7

  8. ANT-Relevant Standards 8

  9. Work Conceptual Model of SC25 WG1 9

  10. Scenario Model of SC25 WG1 Service Function [G/W server, HNRM,,] WiBEEM Dev KNX Dev Core Network IGRS Dev Access Network [ADSL,,] Access Unit [HES G/W, ADSL,,] ECHONET Dev … Dev Access Network [Wireless] Wireless Dev 10

  11. ANT-Relevant Standards of SC25 WG1 Classification: G= General; O= Overview; A= Architecture; Q= Network Management Access Medium: F= Fiber; C= COAX; P= Twisted pair; A= Wireless Interface: J= User/Access Network; H= Service Node/Access Network; B= Direct Server/Access Network; W= User/Wireless Access Network 11

  12. Appendix Logical representation of each scenario 12

  13. Scenario 1 - Provision of Voice/DataVideo Service over existing infrastructure 1a) Provision of Voice/Data/Video services over existing infrastructure 1b) Provision of Voice/Data/Video services over 2-way Cable networks using PSTN or ISDN 13

  14. Scenario 2 - Provision of Voice/Data/Video Services over Cable Networks using B-ISDN 2a) Provision of Voice/Data/Video Services over one-way Cable Networks using B-ISDN with independent control channel 2b) Provision of Voice/Data/Video Services over two-way Cable Networks using B-ISDN 14

  15. Scenario 3 - The use of ADSL or VDSL to provide video bandwidth over copper pairs 15

  16. Scenario 4 - Fibre Access 16

  17. Scenario 5 – Wireless Access 5a) Short-term provision of radio services 5b) Wireless Access Network 17

  18. Scenario 6 - Access using satellites 18

  19. Scenario 7 – Example of Internet Access 7a) Fast Internet access 7b) Internetworking between the Internet and B-ISDN Network 19
