Abstract
An apparatus and method for providing a telephone operating company with the ability to rapidly deploy advanced services into a public switched telephone network includes a service control unit (SCU) for externally controlling call processing of a service call received on a port of a switch matrix. Call control processing is achieved through a high-speed communications link between the switch matrix and the SCU. The SCU receives a new call event notification message from the communications link and selects a service application stored within the SCU to control processing of the service call. One or more primitives is generated by the SCU and output to control actions of the switch matrix, thus controlling processing of the service call. The primitives may include a comprehensive set of primitives (instructions) for call manipulation and control at the switch matrix. The SCU may execute different service application software programs that operate within the SCU for different types of service calls that are under the control of the SCU.
