Peter Wery Chairman ITU-T Study Group 15 Nortel Networks

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 for access, metropolitan and long haul sections of communication networks.
