IPC: H04L29/06
Filed: 1992-03-27
Abstract: The invention concerns an ISDN switching system in which a program module constructed in accordance with the principles of object-oriented programming is used to handle switched calls. The protocol modules used in the protocol architecture (e.g. CCITT recommendations) to standardize the functional switching procedures are represented by object-oriented structural elements. During the implementation of the system program module in the switching system, objects are instantiated for connections and/or calls and/or signalling operations.
