HAFER-3 - 46 - A CONTINUITY VERIFICATION ARRANGEMENT Abstract of the Disclosure A time division switching system having distributed control processors is disclosed. The switching system includes time-slot interchange units having associated subscriber sets and a time-shared space division network for interconnecting the time-slot interchange units. Each of the time-slot interchange units and the time-shared space division network are controlled by separate control processors. In response to called subscriber set identifying information from a calling subscriber set, the control processor associated with the time-shared space division network completes the communication path through the time-shared space division network to connect the time-slot interchange units associated with the calling and called subscriber sets. The control processors in the time-slot interchange units then determine if communication path continuity is present between them before the subscriber sets axe connected to the communication path through the time-slot interchange units. Additionally, arrangements axe included for detecting loss of continuity in the communication path.
