ABSTRACT:
A frame for multiplexing multi-traffic frames of layers on a same carrier wave and an apparatus thereof is constituted by an overhead and a payload. The overhead is constituted by: a data length identifier indicating a frame or a payload length; a flow identifier indicating an attribute of the frame; and a frame header overhead error check (FHEC) storing a result obtained by converting bytes from the head to a specified M-th byte of the frame into a numerical value of n bytes according to a certain coding method. A maximum length of the payload is computed from the data length identifier of the overhead. In the payload, traffic for the layers 1 to 3 can be accommodated. Even if the ATM cell and the frame are multiplexed, since coding methods for the FHEC and the HEC are different, the ATM cell and the frame can be extracted individually.
