  • Abstract
    A framework for controlling transmission quality of international connections is the joint responsibility of CCITT Study Groups XII, XV, XVI and Special D. These study groups recommend rating methods, overall performance objectives, network plans, and equipment characteristics. Still closer cooperation may help to avoid unnecessary regional differences in equipment standards, as in today´s PCM multiplexes.
