Patent ID: 8588219

Claim:
A circuit emulation device for connecting a plurality of time division multiplexing (TDM) circuits to an asynchronous network, comprising: a table storing addresses of other circuit emulation devices on the asynchronous network, each of the TDM circuits corresponding to one of the addresses as a destination address; a packet assembly section for bundling TDM data of TDM circuits having same destination address by referring to the table, to assemble a multiplex packet which has a packet header including the same destination address as its destination address; and a transmitter for transmitting the multiplex packet to the destination address through the asynchronous network, wherein the packet assembly section comprises: a packet generation section for generating an individual packet from TDM data of each TDM circuit; an individual payload generation section for generating an individual TDM payload by deleting header information other than the circuit destination information from the individual packet; and a multiplex payload generating section for generating a multiplex payload of the multiplex packet by bundling individual TDM payloads of the same destination address by referring to the table.
