PCM SWITCHING NETWORK PROVIDING INTERLEAVING OF OUTGOING AND INCOMING SAMPLES TO A STORE DURING EACH TIME SLOT

In a space-time-space switching network an interleaving technique is used to enable increased time (doubling) for read and write operations. The system is realized by adding input and output registers to an exemplary system and adding controls for the registers. The addition of the registers and controls specifically enables a coded sample from subscriber A to be read out in the speech store during a first cycle, a coded sample from subscriber B to be read out in the same store in the next cycle and to be transmitted through the network during the next cycle.
