Abstract:
A highway switch control system for controlling a time division multiplex highway switch of T-S-T three-stage switches in a multiprocessor typed electronic switching system comprising:a plurality of sets of first switches operating in a time sharing switching method, second switches operating in a highway switching method, third switches operating in a time sharing switching method, and control processors for controlling each respective first, second, and third switches, each said set comprising one of said first switches, one of said second switches, one of said third switches, and a corresponding one of said control processors; interconnecting means for interconnecting said control processors in each set to each other; first output highways for connecting each of said first switches in every set to all said second switches of all sets; and second output highways for respectively connecting said second switches to said third switches in every set, two of said control processors getting information about spare time slots of each other's corresponding switches through said interconnecting means and deciding time slots for use in a connection, thereby controlling the connection between their corresponding switches.
