ABSTRACT:
A communication system comprises a communications network coupled at least to a terminal unit. The communications network is coupled to a service device which comprises a switching center, a controller, and a data bank. The data bank contains at least a service logical program. A terminal unit generates a first parameter and a second parameter for sending as a single transmission to the service device. The controller extracts a service logical program from the data bank in response to the first parameter. The controller further controls the switching center in response to the second parameter based on the extracted service logical program.
