Buffer capacity analysis under the influence from timing jitter in SDH system

The influence on the buffer capacity from timing jitter with different features has been analysed and the method of selection of the buffer capacity corresponding to a concrete communication system is proposed. Under multiple-sources of timing jitter, a stable result for the buffer capacity is given through the pointer adjustment process, bit accumulation in the buffer and and the jitter variations. This result shows that the buffer capacity can be reduced greatly compare to the conventional method.
