A delivery unit for interfacing telecommunications media to a switching matrix. The delivery unit functions are partitioned into a number of application modules. Each application module has a controller that handles control messages. Each controller is built from the same circuitry and operates in the same manner so as to provide a common software platform for originating and terminating control messages within the delivery unit.

[ What is claimed is:] [1.]1. A delivery unit that interfaces telecommunications media and a switching system, comprising:a number of application modules, each having application circuitry operable to perform functions associated with conversions between high level telecommunications signals carried by said media and DS0 network data represented by electrical signals switched by said switching system;a bus control module having application circuitry that controls access to ingress and egress buses carrying the DS0 network data represented by said electrical signals;wherein said ingress and egress buses provide transport of said DS0 network data between said application modules;wherein said application modules each have controller circuitry that is substantially the same for each of said application modules, said controller circuitry operable to originate and terminate control datagrams containing control messages, and said controller circuitry comprising a processor that processes incoming of said control messages and generates outgoing of said control messages.
