| Digital switches are one of the main components of the data transmission networks, and their modeling in applications such as traffic measurement, fault diagnosis, and operator training,have significant importance. In this paper, signaling of a digital switch is modeled and simulatedusing Colored Petri Nets. Colored PetriNet can support various data types and due to its intuitive graphical representationis known as an efficient tool for modeling of Discrete Event Systems (DES). In this papera digital switch is considered as a DES and its signaling is modeled using a CPN. Signalingis a sustainable and comprehensiveprotocol that can integrate various communication services into digital and analog telephone subscribers. The protocol cited in this paper,meets all the requirements for communication between digital databases and its role in the communications system is the same as one in computer networks. In this paper the signaling state is limited to a successful call between twosubscribers. In addition, the reachability graph is extracted for the CPN which contains all possible events in the DES and can be used for supervisory control tasks such as fault diagnosis process. |
