Abstract: PCM words transmitted on a number of incoming and outgoing links during time slots according to a time division multiplex system are space interchanged by utilizing a circulating shift register wherein at the beginning of their allotted time slots, each of incoming PCM words is registered each in an associated shift register stage. The circulating shift register is stepped by a clock pulse so fast that each PCM word is stepped through all shift register stages during the respective time slot. Control words, each associated with one of the time slots and with one of the outgoing links, determine during which clock pulse an outgoing link is connected to the output of its associated shift register stage. A buffer memory arranged between the circulating shift register and the outgoing links re-establishes the correct time division multiplex system for the outgoing PCM words.
