    5. Outline • End User Perspective • Conceptual Framework • Next Generation Telco ..

    6. End User - Internet Telephone

    7. Komponen VoIP / Menit • Telkom Rp. 75 / menit • ISP Rp. 75 / menit • Hook-off Service • http://www.net2phone.com • Delay <250ms

    8. Biaya SLI / Menit (1US$=Rp8000)

    9. Solusi Kantor Kecil / Rumah • Satu (1) Saluran VoIP • Internet PhoneJACK US$150 • Internet LineJACK US$220 • Internet PhoneCARD US$170

    10. Komunitas WARNET • Asosiasi-warnet@itb.ac.id • Free subscribe: • Asosiasi-warnet-subscribe@itb.ac.id • Komunitas e-commerce • Mastel-e-commerce@egroups.com • Warta-e-commerce@egroups.com • E-commerce@itb.ac.id

    11. Kebutuhan WARNET • Line telepon koin • Leased line analog Regional Network / DIVNET • Akses ke box JAMUS V.35 / RS.449

    12. WARNET “tanpa” Telkom WARNET ke Internet • Satellite DirectPC – US$200 / card • KabelVision – Rp. 300.000 / bulan Jaringan WARNET • 2-11 Mbps 2.4 GHz US$250 / card

    13. Teknologi VoIP sederhana

    14. Internet Telephone

    15. Dialer

    16. Video Conference

    17. Internet PhoneJACK

    18. Connection PhoneJACK

    19. Internet PhoneCARD

    20. Voice Quality Comparison

    21. Solusi Gateway Sederhana

    22. VoiceTronix (8 port)

    23. VoIP untuk WARNET • Investasi WARNET+ • Invest Card DSP ~US$150 / kanal. • Estimasi ke US biaya / menit • US$0.13 + Rp. 75 + Rp. 75 • Estimasi ke US biaya SLI 001 • Rp. 9900-8300 / menit

    24. Issue Desktop VoIP Solution • Ease of Installation. • Infrastructure. • Flexibility. • Compatibility. • Ease-of-Use. • Quality. • Cost • Growth Path. • Base for Applications.

    25. Aplikasi Desktop VoIP • IntraNet Communication • Remote Call Forwarding • Distributed Call Center • Virtual PBX • Line Doubling • Personal Iphone Calling

    26. Personal Iphone Calling

    27. Intranet Communications

    28. Remote Call Forwarding

    29. Distributed Call Center

    30. Virtual PBX

    31. Line Doubling

    32. Mobile User

    33. Mobile User • Internet Locator Service (ILS) • Mapping Name Number  Dynamic IP

    34. Internet Locator Service (ILS) • http://www.icq.com • ILS & chat system • http://www.tzo.com • Dial your DNS name.

    35. Conceptual Framework • H.323

    36. H.323 Benefit • Codec Standards. • Interoperability. • Network Independence. • Platform & Application Independence. • Multipoint Support. • Bandwidth Management. • Multicast Support. • Flexibility. • Inter-Network Conferencing.

    37. H.323 mengatur .. • Video Codec (H.261 dll). • Audio Codec (G.711, G.723 dll). • Data channel (T.120 dll) e-board dll. • System Ctrl Unit (H.245, H.225.0 dll). • H.225.0 layer – error detection, error correction and frame sequencing.

    38. Open Standard

    39. Komponen H.323 • Terminal • Gateway • Gatekeeper • Multipoint Control Unit (MCU)

    40. Terminal H.323 • Provide Real-Time. • Provide Two-way communications. • H.245 – nego channel usage & capabilities. • Q.931 – Registration/Admission/Status (RAS). • T.120 – Data Conferencing Protocols.

    41. Komponen H.323 • H.323 Gateway • Interface H.323 terminal – WAN terminal. • H.323 Gatekeeper • Address Translation (E.164 – IP) • Admission Control. Authentication. • Bandwidth Control. • Zone Management. • Call Control & Management • (e.g. VoIP – PSTN)

    42. H.323 Gateway • Optional! • Translation function between H.323 conferencing endpoints and other terminal types. • Translation between transmission formats (i.e. H.225.0 to H.221). • Translation between communications procedures (i.e. H.245 to H.242). • Translation between audio and video codecs. • Performs call setup and clearing on both the LAN side and the PSTN side.

    43. H.323/PSTN Gateway

    44. Gatekeeper • The most important component asct as a virtual switch of an H.323 enabled network. • It acts as the central point for all calls within its zone and provides call control services to registered endpoints.

    45. Gatekeeper • Address translation from LAN aliases for terminals and gateways to IP or IPX addresses (e.g E.164 – IP) • Bandwidth management. • Route H.323 calls. • Bill for calls.

    46. Gatekeeper Zone

    47. Isu Quality of Service (QoS) • Kekurangan Bandwidth • Delay terlalu lama. • Jitter / Variasi delay.

    48. QoS • Resource Reservation Protocol (RSVP) • Real Time Protocol (RTP) • Compressed Real Time Protocol (CRTP) • Traffic Shaping • Queuing: Custom Queuing, Weighted Fair Queuing. • Congestion Control: Random Early Detection. • Effisiensi Jaringan: link fragmentation & interleaving.
