CONFIGURATION AND CONTROL UNIT FOR A HETEROGENEOUS MULTI-SYSTEM Abstract Of The Disclosure Describes a configuration and control unit (CACU) for a heterogeneous multi-system containing processors which may be of different types, channels, one or more channel crossbar switches which may be of different sizes, various I/O channel switches, I/O control units and I/O devices. The CACU is the focal point in the multi-system for confi- guration control over all of these system heterogeneous components. The CACU enables the configuration of any switchable part of the entire multi-system to be established and changed at any time due to new processing requirements or failure of part or all of the system. The CACU contains a parallel wire line (PWL) adapter for providing DC switching control over components connected through channel crossbar switches and/or channel I/O switches. The CACU also has a time multiplexed (TM) adapter connected via serial time multiplexed lines (TML's) to remote modem adapters (RM's) with devices controlled by or switched by the CACU. A TML can provide serial pulse control switching for components connected to channel crossbar and/or channel I/O switches, which transfer data directly Prom the processor channels whereby the data bypasses the CACU. A TML can also provide serial pulse data to other devices which have their data passed through and switched by the CACU for switchable communication with any processor. A persistent storage unit is providable in the PWL adapter and TM adapter for perma- nently storing the current configuation of PWL and TML connected units. Upon failure of any one or more units -1- connected to the PWL adapter or TM adapter, the settings in the persistent storage devices can recover the operating configuration of devices in the multi-system.
