发明名称 Asynchronous transfer mode digital telecommunication network terminal equipment synchronization device
摘要 PCT No. PCT/FR92/00912 Sec. 371 Date May 28, 1993 Sec. 102(e) Date May 28, 1993 PCT Filed Oct. 1, 1992 PCT Pub. No. WO93/07695 PCT Pub. Date Apr. 15, 1993.A synchronization device, in an asynchronous transfer mode digital telecommunication network terminal equipment consists of: a jitter filter for filtering transfer jitter introduced by a network of this kind and affecting the clock frequency at which the equipment receives data via the network and for slaving the frequency of a local clock signal supplied by a local clock internal to the equipment to the output signal of the filter; buffers (MTB1, MTB2) written with the data at the clock frequency at which data is received by the equipment; and read controllers (5, 5') for reading the buffers at the clock frequency of the output signal of the filter with a time-delay relative to writing determined in such a way as to minimize the risks associated with excessively low bit rates in the recovery of data after such reading during the reaction time of the filter without departing from a permissible margin for the data recovery time-delay.
