Schaltungsanordnung zur Aufbereitung von PCM-Systemen zum Zwecke der Vermittlung

DE 3228518 A UPAB: 19930925 The application is to connecting high speed pulse code modulated data systems together into a transmission system or data exchange. The PCM system is connected to the transmission network through an interface. It comprises a register for converting from series to parallel operation, two parallel buffers for the address and contents of a time slot, and a time slot counter. It also contains the necessary synchronisation and timing pulse checking units. A control unit and a unit for determining priority regulate the instants during which the relevant PCM system (PS) is connected to the transmission bus. The system operates by using time slot numbering. It allows a large reduction in the amount of information which must be transmitted in addition to the useful data. 0/
