Abstract
An integrated telecommunication system for multiple telephone line response and processing having a plurality of interface circuits, each of which is adapted to control the physical connection to a plurality of telephone line channels, control communication on a group of telephone line channels connected thereto. Each interface circuit includes a high speed interface microprocessor and a first data storage associated therewith. A first bus system interconnects the plurality of interface processor circuits to signal processor circuits. Each signal processor module includes a cross-point switch and a high speed digital signal microprocessor for analyzing the incoming signals and compressing the data therein, a second data storage associated therewith, and one or more of a plurality of telecommunication function circuits controlled thereby. A multi-bus system connects each of the plurality of interface processors to each of the plurality of signal processor circuits and to a main system control processor and a third data storage. The high speed processing requirements of each group of telephone lines is performed by the respective interface control processor and a digital signal micro…
