摘要： A frame transmitting apparatus includes a transmitting unit which transmits, when a change is made to a value in a predetermined field of a frame, the frame including the predetermined field with the changed value a predetermined number of times in succession. A frame receiving apparatus includes a receiving unit which receives the frame and an acceptance processing unit which recognizes the value in the predetermined field of the received frame and conducts acceptance processing. The acceptance processing unit compares, when the value is different from a currently accepted value, the value with an expected value; accepts the value when the value matches the expected value; and accepts, when the value does not match the expected value, the value after receiving the same value the predetermined number of times in succession.

摘要： A frame transmitting unit divides a payload area of an upper-layer frame into a plurality of slots, maps a lower-layer frame to one or more of the slots, and transmits the upper-layer frame including connection information that indicates which one or more of the slots the lower-layer frame of a same type is mapped to. The frame synchronization detection unit identifies, as one or more allocated slots, the one or more slots to which the lower-layer frame of the same type is mapped, on the basis of the connection information, and detects the frame synchronization by identifying a frame head signal of the lower-layer frame of the same type that is mapped to the one or more allocated slots.
