Patent Number: 7,042,904

Title: Method and apparatus for transmitting multiple signal, method and apparatus for receiving multiple signal, multiple signal transmission method and multiplexer/demultiplexer

Abstract: A client channel receiving processor unit converts each reception client signal of a 10B-character form into a GFP frame form. A mapping unit maps the client signal of the GFP frame form on a channel of virtual concatenation. A SONET/SDH processor unit transmits or receives a SONET/SDH frame, in which a GFP frame is mapped, to/from a network. A demapping unit separates each channel of the SONET/SDH frame received by the SONET/SDH processor unit. A client channel transmitting processor unit detects the client signal of the GFP frame from each separated channel to convert the signal into a 10B-character form.
