Thank you all Acknowledgements SG 15’s significant achievements would not have been obtained without the dedicated effort of many individuals working as a coherent team. Thank you all The SG Vice-Chairmen and WP Chairmen The Rapporteurs and Editors Those with ‘Other Roles’ (SG Representatives) The TSB counsellor and his Assistant (Paolo Rosa, Isabelle Garde) Other TSB staff, too numerous to name The SG 15 members for their participation and contributions

Peter H.K. Wery Chairman ITU-T SG 15 Peter H.K. Wery has been involved with ITU-related activities since 1969, when he represented SEL (Germany) at joint CCIR/CCITT Study Group CMTT (Sound Program and TV signal transmission). Since 1976 Peter has participated pro-actively for Nortel Networks (Canada) in a variety of ITU-T Study Groups and roles, including Rapporteur, Liaison Rapporteur, Working Party chairman and SG Vice-chairman. Peter has successfully chaired Study Group 15 (Optical and other Transport Networks) since 1996. Under his leadership Study Group grew into the largest Study Group of the ITU-T, developing over 260 Recommendation texts, predominantly in its core competency areas of Network Access and SDH & Optical Transport Networks and Technology.
