Abstract:
A local exchange system comprising a plurality of trunks connected to respective nodes outside the local exchange system for receiving a signal in original data format including a destination address, a plurality of common signal handlers, disposed for respective said trunks, for converting a received signal through a corresponding one of said trunks into a local area network data, and for judging whether the received signal is directed to the local exchange system based on the destination address of said received signal using a stored routing table, a central processor for controlling operations of the local exchange system, and a local area network for coupling said common signal handlers and said central processor together for transmitting said local area network data therebetween, said central processor receiving and processing said local area network data if said destination address is directed to the local exchange system, each of said common signal handlers converting said local area network data into said original data format for transmission through a corresponding one of said trunks if said destination address is directed to a corresponding one of said nodes that is outside the local exchange system.
