Regarding the Views Expressed

P IEEE SA St d d B d O ti M l J 2005Per IEEE-SA Standards Board Operations Manual, January 2005:

“At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall make it clear that his or her views should be considered the personal views of that individual rather than the formal position, explanation, or interpretation of the IEEE.”

The views I am expressing on IEEE standards and related products should NOT be considered the formal position, explanation, or p , p ,interpretation of the Ethernet Alliance.
