PURPOSE: A device of processing multi frames is provided to reject a currently performed multi frame when a BIP(Bit Interleaved Parity)-8 error is generated in a frame after the first frame, and to carry out an operation of a next multi frame, thereby reducing load and carrying out other event during a saved time. CONSTITUTION: A multi frame unit(30) is composed of many frames. An ADM(Adaptive Delta Modulation) unit(30) checks whether an error is generated in a transmitted multi frame, and transmits a checked result. A PLD(32) is composed of a buffer and a process logic unit. The buffer stores changed information of data processed in the ADM unit(30). The process logic unit rejects the current multi frame, and outputs a command of processing a next multi frame. The PLD(32) transmits the command of processing the next frame to the ADM unit(30) for a transmission error of the data processed in the ADM unit(30). A CPU(33) outputs a command of not-processing the next frame consisting of the current multi frame, by an IRQ(Interrupt Request) or a self monitoring of the PLD(32). A mapper/framer(34) maps and frames the data outputted from the ADM unit(30). |
