The present invention provides an innovative method of transmitting a multiframe signal generated in accordance with the international standard synchronous data hierarchy. Multiframe signals comprising a plurality of standard containers may be transmitted within a network node or system employing an STM-1 frame in a novel manner. Each standard container is provided directly to an STM-1 frame processor. The STM-1 frame processor creates a modified STM-1 frame for transmission. Because the VC-4 path overhead is not generated, the multiframe synchronization (MFS) information for the standard container is written to the STM-1 user definable F1 byte by a link processor. The modified STM-1 is then converted to an optical signal and transmitted to a remote part of the node where the STM-1 is received. The STM-1 overhead is thereafter removed and the contents of the F1 user byte is obtained. The receiving node uses the MFS information to access the data contained within the multiframe signal.
