Error Performance Events for SDH Multiplex and Regenerator Sections Series G: Transmission Systems and Media Digital Systems and Networks Digital Networks - Quality and Availability Targets Study Group 13
ITU-T Rec. G.828 [6] specifies error performance parameters and objectives of international,
constant bit rate synchronous digital paths. Error performance objectives of ITU-T Rec. G.828 refer
to the hypothetical reference path (HRP) of a length of 27 5
