Abstract

In a reconfigurable communications system, circuit status bits are stored in a first matrix of rows associated respectively with predefined network configurations and columns associated respectively with predefined circuit configurations. Destination status codes are stored in a second matrix of rows associated respectively with the circuit configurations and columns associated respectively with switching nodes of the system. Each circuit configuration comprises one or more transmission links and each circuit status bit stored in each column of the first matrix pattern indicates the presence or absence of the circuit configuration associated with that column. Each destination status code indicates the presence or absence of transmission links from each switching node to possible destination nodes. In response to a manual command, those of the circuit status bits stored in one of the rows of the first matrix are respectively multiplied with those of the destination status codes stored in each column of the second matrix, and the multiplied binary values are summed so that network configuration data is derived with respect to a desired network configuration, which is then transmitted to the switching nodes to reconfigure the system. In a modified embodiment, a difference is detected between the network configuration data suscessively derived with respect to previous and most recent network configurations and transmitted as network configuration signals to the switching nodes.
