1. In a communication switching system controlled by a control processor serving at least two classes of port circuits having different types of associated communication devices where said control processor includes a plurality of connection processing algorithms and each algorithm is associated with an identifiable class of port circuits, a processing arrangement for providing a requesting port circuit of one class of port circuits with access to any one of said connection processing algorithms associated with a different class of port circuits comprising:

  • means for identifying said one class of port circuits associated with said requesting port circuit;

    means responsive to said identifying means for implementing the execution of a one of said connection processing algorithms associated with said requesting port circuit;

    means further responsive to said identifying means for indicating when said requesting port circuit requests access to a specified one of said connection processing algorithms associated with a different class of port circuits;

    means responsive to said indicating means for terminating the execution of said one connection processing algorithm associated with said requesting port circuit; and

    means responsive to said terminating means for implementing the execution of said specified one of said connection processing algorithms associated with said different class of port circuits.
