Apparatus and method for identifying boundary of asynchronous transfer mode cell |
摘要 |
An ATM cell boundary identification apparatus and method. The apparatus comprises an idle cell inserting unit for inserting an idle cell into a cell transmitted from an ATM layer to be matched therewith in its speed; a header error cell generating unit for generating a header error cell by means of header information of the cell transmitted from the idle cell inserting unit; a cell scrambling unit for scrambling payload of the cell received from the header error cell generating unit; a transmission framer for converting the cell obtained in the cell scrambling unit to be suitable to a frame E1; a line interfacing unit for transmitting a transmission frame obtained in the transmission framer to a transmission line after converting it into a bipolar transmission signal, and for transmitting the cell received from the transmission line to a reception framer; a reception framer for identifying a boundary of the cell according to each time slot of the cell transmitted from the line interfacing unit to thereby extract a header error cell; and a header error cell detecting unit for detecting the header error cell extracted from the reception framer, and checking whether the extracted cell is effective or not.
