FOREWORD
The ITU munication Standardization Sector (ITU-T) is a an of the International -
munication Union. The ITU-T is responsible for studying technical, operating and tariff questions and issuing
mendations on them with a view to standardizing munications on a worldwide basis.
The World munication Standardization Conference (WTSC), which meets every four years, established the
topics for study by the ITU-T Study Groups which, in their turn, produce mendations on these topics.
ITU-T mendation was prepared by the ITU-T Study Group 15 (199x-199x) and was approved by the
WTSC (Place, Month xx-xx, 199x).
