Abstract :
The frame aligner is a key part in a digital multiplexer/demultiplexer system. A novel error tolerant frame alignment methodology is presented in this paper. Analysis shows that this method complies with ITU-T recommendation and improves the performance. The parameters of frame aligner and framing pattern are carefully selected. Finally, the parallel realization of a frame aligner with the proposed method, which can lower the working frequency and power, is applied in an STM-4 system
