Abstract
A communication method and switching system in which voice and data signals are communicated through the system by a programmed controlled switching processor. The switching processor reads these signals from an input memory where they were transferred from telephone stations and data terminals by a scanner. The voice and data signals are transmitted to telephone stations and data terminals by the switching processor storing these signals in an output memory from which they are retransmitted by a distributor to the telephone stations and data terminals. The intelligent processor reads data signals from the input memory and assembles these signals into data packets which are temporarily stored in the data memory. Subsequently, the intelligent processor transmits these data packets by storing the data signals in the output memory. The intelligent processor is controlled by program instructions from its program memory and data stored in a data memory by a parameter processor which has associated program and data memories.
