INTERNATIONAL TELECOMMUNICATION UNION ITU-T RECOMMENDATION SUMMARY Rec. No. : I.113 Title : Vocabulary of terms for broadband aspects of ISDN Study Group : XVIII - ISDN Version : Revised Date of adoption : 1991 Notes : Recommendation I.113 consists primarily of those terms and definitions that are considered essential to the understanding and application of the principles of broadband aspects of the integrated services digital network (B-ISDN). They are not exclusive to B-ISDN and are recommended also for application, in so far as they are relevant, to other types of telecommunication networks. Included are terms that may already be defined in other CCITT/CCIR Recommendations. However, the definitions given in Recommendation I.113 embrace only the essential concepts and on that basis it is considered that they are not inconsistent with the more specialized definitions that appear in those Recommendations.
