  • Plural data processor groups controlling a telecommunications exchange
    Patent number: 4493030
    Abstract: A data processing system having a large number of data processors (1-4) grouped in `clusters` is used in the control of a telecommunications exchange. The arrangement is such that any one of the processors may pass data to any other of the processors, in its own cluster by way of a synchronous data bus (5), or on other clusters by way of an interface (18, 19) and an asynchronous data bus (22). The arrangement permits larger number of processors (1-4) to have access to storage without undue delay in access to stored data.
