Error performance of an international digital connection operating at a bit rate below the primary rate and forming part of an Integrated Services Digital Network
This Recommendation specifies error performance events, parameters and objectives of a N ×64 kbit/s circuit-switched digital connection (1 ≤N ≤24 or ≤31 respectively) used for voice traffic or as a "Bearer Channel" for data-type services. The application of this Recommendation is limited to international digital connections, operating below the primary rate of the digital hierarchy, that use equipment designed prior to the adoption of revised ITU-T Rec.G.826 on 14 December 2002.
