1. A bus control module for a delivery unit, which interfaces high level network signals to a switching matrix and has a number of application modules that perform various network data transport functions, comprising:

  • bus control application circuitry operable to receive ingress frames of data carried on ingress links from said application modules, to multiplex subframes contained by said ingress frames to an egress bus, and to map said subframes to egress frames carried on said egress bus;

    wherein said ingress frames and said egress frames may contain both control data subframes and network data subframes, each network data subframe having a payload to carry network data, each control data subframe having a payload to carry control data;

    a bus interface that receives control data subframes on said egress bus and that delivers control data subframes to said application circuitry; and

    a controller in communication with said bus interface that originates control data subframes for insertion on said egress bus and terminates control data subframes received on said ingress links.
