QoS / NP and QSDG activity

• Luis S. Cardoso
• QSDG Chairman

The Quality of Service Development Group ( QSDG
) which is in nature an operational group
including a field trial group was created in
the Study Group 2 organisation in 1984.
3
The original idea came from Mr. C. McCauley from
ATT who felt that, despite their usefulness,
the writing of Recommendations as such or
drafting a handbook was not enough to improve
the quality of service. Telecommunications
people need to come together, communicate and
help each other, to achieve the best actions for
improvements and to have a free exchange of
views and ideas in a multilateral environment.
