25. 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 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.
