FOREWORD
The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the International Telecommunication
Union. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them
with a view to standardizing telecommunications on a worldwide basis.
The World Telecommunication Standardization Conference (WTSC), which meets every four years, established the topics for
study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
ITU-T Recommendation H.261 was revised by the ITU-T Study Group XV (1988-1993) and was approved by the WTSC
(Helsinki, March 1-12, 1993).

Sector.
As a consequence of a reform process within the International Telecommunication Union (ITU), the CCITT ceased
