ABSTRACT:
A supervisory system for a network of communications stations in which a response to a query to one station may be received and interpreted by a plurality of other stations in the network. Upon receipt of a command from a master station, a slave station sends a responsive signal that includes the identity of the command. Each master station monitors the network and keeps track of the status of each slave station by updating its status records upon receipt of one of the responsive signals containing the command identity. Each master station operates independently and all of the stations may be master stations. The multiple master stations may each attempt to exert control over the slave stations in the network at any time.
