  1. ITU-T Study Group 15 Peter Wery Chairman ITU-T Study Group 15 Nortel Networks

  2. Responsibility and Mandate • Focal point in ITU-T for studies on optical and other transport networks, systems and equipment. This encompasses the development of transmission layer related standards foraccess, metropolitan and long haul sections of communication networks. • Lead Study Group on: • Access Network Transport (ANT) • Optical Technology

  3. Network Access SG 15 Work Program • Question 1/15 (WP 5/15) • Access Network Transport • Focus on Lead Study Group activity • Question 2/15 (WP 1/15) • Optical systems for access networks • Focus on B-PON; G-PON • Question 4/15 (WP 1/15) • Transceivers for customer access and in-premises phone line networking systems on metallic pairs • Focus on xDSL

  4. Optical systems for access networks • Work started in 1996 • B-PON related Recommendations • G.983-series • 8 Recommendations (basic; mgmt.& ctrl.; serv. cap.) • 2 Recommendations consented April 2004 (mgmt. & ctrl. I/Fs) • G-PON related Recommendations • G.984-series • 3 Recommendations approved (basic; phys. media dependent layer; transmission convergence layer) • 1 Recommendation consented April 2004 (mgmt. & ctrl. I/Fs)

  5. DSL systems for access networks • Work started in 1996 • Phone line networking systems related Recommendations • G.989-series • 3 Recommendations (basic; payload format; isolation function) • HDSL & SHDSL related Recommendations • G.991-series • 2 Recommendations (transceivers) • ADSL related Recommendations • G.992-series • 5 Recommendations (ADSL splitter & splitterless; ADSL 2; ADSL 2+) (cont’d)

  6. DSL systems for access networks (cont’d) • VDSL related Recommendations • G.993-series • 1 Recommendation (basic) • Revised version consented April 2004 (transceiver & line code) • OtherDSL related Recommendations • G.994-series – Handshake procedures • G.995-series – Overview of DSL Recommendations • G.996-series – Test procedures • G.997-series – Physical layer management • Future work • IP and IP-based, Ethernet and other services over DSL • Bonding multiple DSL • Single ended line testing • Management of DSL systems/equipment • Enhancements to existing Recs.

  7. Lead SG on Access Network Transport • Mandate • Define, maintain overall framework (other SGs, SDOs, Forums/Consortia) • Own Questions • Coordinate, assign and prioritize work in other SGs • Consistent, complete, timely standards • Implementation • ANT Standardization Overview (who, what, when) • ANT Standards Work Plan (holes, lack of progress, priorities) • Provide ‘value added’ http://www.itu.int/itudoc/itu-t/com15/ant/index.html
