The invention relates to a
delay equalization method for realization of service code
stream irrelevance by automatic mark
insertion. According to the scheme, a whole set of channel
equalization device which includes a sending part and a receiving part, is adapted to a multi-channel and multi-
route network environment, and overcomes channel time varying influence is constructed by technical development such as code
stream synchronization, cache adjustment, code
stream aligning and the like, the device comprises functions of code stream adaption, mark
insertion, code stream sending, code stream receiving, synchronous adjustment, cache aligning
processing, uniform
clock output and the like, the reliability and the stability of
channel data transfer can be improved, and accurate and inerrant
data transmission performance and stable and constant
signal transfer time
delay can be provided on the condition of multi-channel switching.
