U interface (UNI). The American variant is specified by the American National Standards Institute (ANSI) in T1.601. In Europe, the NT1 belongs to the network operator, so the user doesn't have direct access to the U interface. The European variant is specified by the European Telecommunications Standards Institute (ETSI) in recommendation ETR 080. The ITU-T has issued recommendations G.960 and G.961 with world-wide scope, encompassing both the European and American variants of the U interface. Like all other ISDN basic rate interfaces, the U interface carries two B (bearer) channels at 64 kbit/s and one D (data) channel at 16 kbit/s for
