  • Call initiation delay arrangement for digital data switching system
    Patent number: 3959599
    Abstract: A digital data switching system is designed for rapid calling of data machines by subscriber polling equipment. In the event, however, that calls cannot be completed due, for example, to busy conditions of called machines or to failure of machines to answer the calls, the polling equipment is precluded from rapidly initiating new calls that overload the common control equipment. A timing circuit delays the initiation of new calls by blocking requests for the services of the common control equipment if completion of the previous call is unsuccessful and the common control equipment is continuously active.
