Power saving tutorialsA series of three one-hour power saving tutorials were held 13-15 February 2008Each early-morning session attracted about 100 participantsSG15 can play its part in helping to reduce greenhouse gas emissions by implementing energy saving techniques in its standardisation work programme by focusing on the goals of reduced power consumption and energy efficiencyConsider opportunities and techniques for power saving in DSL and PON as well as energy efficient Ethernet


21


Developing country issues

SG15 action plan on developing country issuesPreparation of a new Supplement 42 on the use of the ITU-T Recommendations related to Optical Technology to give to developing countries improved capability in the

application of standards also seen as benefiting the wider telecommunication

industry, particularly manufacturers and operators, which could benefit from the greater involvement of developing countries in the making and application of standards.
