Defines end-to-end error performance parameters and objectives for international digital paths which operate at or above the primary rate and for international digital connections which operate below the primary rate of the digital hierarchy. Deals with the performance of PDH paths, and of those SDH paths using equipment designed prior to the adoption of ITU-T Recommendation G.828 in March 2000.
