Title:
CIRCUIT AND METHOD FOR MULTIPLEXING AND DATA SERVICE UNIT
Document Type and Number:
Japanese Patent JPH09172456
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce overhead in a system for multiplexing a frame from a different source on a single frame relay virtual circuit. SOLUTION: A multiplexing circuit 183 is provided with frames relayed by first and second logical channels through a single frame relay virtual circuit 140, respectively related channel flags and logical channel generation circuits 126 and 186 for specifying first and second headers. Then the circuit includes a multiplexer inserting the channel flag and the second header into each frame of a second data stream and inserting a flag to which the first flag is related only to the frame of a first data stream coinciding with the channel flag so as to relate the frames of the first and second data streams respectively with the first and second logical channels. Thereby there is not the first header in each frame of the first data stream.
