Abstract: According to the characteristic of tributary unit(TU) point justification in synchronous digital hierarchy (SDH), this paper provides a method of software and hardware for designing adaptive bit-leaking. The content is a solution of making random signal, designing the software flow, and circuit design. Then it gives the result of four tests for combined jitter measurement in SDH.
