<P>PROBLEM TO BE SOLVED: To provide a multi-lane signal transmitting apparatus and its receiving apparatus capable of transmitting and receiving a multi-lane signal using the same inverse multiplexing scheme even when optic modules having different number of transport lanes are selected according to purpose of use. <P>SOLUTION: Each OTUk capable of containing a client signal in a transport hierarchy signal (OTUk-Xv) is defined as a virtual container, and while Y virtual lanes are allocated to each virtual container X, identification information for the allocated virtual lanes is inserted into an overhead area and a transport hierarchy multi-lane signal is transmitted in the form of OTUk-XvYd. At the receiving end, the identification information inserted into the overhead area of the transport hierarchy signal in the form of OTUk-XvYd is extracted, and after the skew of the received signal is compensated, virtual lane signal is aligned for each virtual container, and restored with an OTUk-Xv signal that is an original transport hierarchy signal. <P>COPYRIGHT: (C)2010,JPO&INPIT |
