Power saving tutorials
A series of three one-hour power saving tutorials
were held 13-15 February 2008
Each early-morning session attracted about 100
participants
SG15 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 efficiency
Consider opportunities and techniques for power
saving in DSL and PON as well as energy efficient
Ethernet

Developing country issues
SG15 action plan on developing country
issues
Preparation 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.
