ABSTRACT:
A switching system comprises a time division switch for forming a fixed path through which a line circuit and a trunk circuit are connected to each other. Both the line circuit and the trunk circuit have a discrimination function and a transfer function. For example, when the trunk circuit receives system data packets including predetermined system data packets from a call processor, the trunk circuit discriminates the predetermined system data packets from the system data packets using an identifier of each packet. The predetermined system data packets are transferred to the line circuit through the fixed path of the time division switch. Receiving the predetermined system data packets from the trunk circuit, the line circuit stores the predetermined system data as well as system data for the trunk circuit received from the call processor into a memory thereof. Using the predetermined system data and the system data for the trunk circuit stored in the memory, the line circuit processes communication information packets received from the terminal or the network.
