<p>The invention relates to a circuit switch connected between transmitting and receiving devices (10) and comprising a switch memory 4) including a number of memory positions for entering of received time slots from said transmitting devices (10S), a control memory (18) including a number of memory positions for entering read-out addresses for said switch memory, an addressing path (16) from said control memory to said switch memory for a read-out address in the latter, from which read-out of data shall be made towards a receiving device (10M), and a control unit (20) for entering said read-out addresses in said control memory and for receiving information from said devices related to the connect and disconnect of calls. The addressing path (16) from said control memory has an alternative communication path towards said receiving devices, and each memory position in the control memory includes a specific position for an indicator bit (32) containing information with respect to whether read-out of a time slot towards a receiving device should be made from said switch memory or from said control memory.</p> |
