BASIC SWITCHING UNIT FOR AN APPARATUS USED TO SHUFFLE DIGITAL STREAMS WHICH HAVE BEEN MULTIPLEXED BY TIME DIVISION OF DIGITAL TRIBUTARIES AT DIFFERENT RATES

摘要

the switch unit is a basic equipmentmultiplexed by multiplexing a digital mixing traintemporal digital tributaries at various flow rates. thisthe switching unit includes, for each elementary.support incoming frame relay deviceextraction of signals constituting units.the multiplexing frame to make into a memory.the so-called memory component signals units.multiplexing to brew, able to contain at least n signals.where n is the period of the low flow channel ofthe structure of a device for multiplexing.an entry of the memory in synchronism with therate of extraction, to separate the addresses.the signals constituting multiplexing units to dodistinct and identical addresses for signalsa multiplexing unit which replace thethe frequency of rewriting of each address is associated with theperiod of repetition of the signals written in the address.a device for reading from the memory.consistent with the pace of integration into the frames.out of signals constituting multiplexing units.to address: to be governed by the law ofdistribution.
