PURPOSE:To attain identification of data for identification without need of an error check decoding means or an error correction processing means by reading coded identification data from a storage means and comparing the data with a received data. CONSTITUTION:Coded ID data outputted from an ID generator 12 of a transmission section 10 is written in advance in an ID memory 28. An ID detector 27 compares the ID data added to a reception data in the unit of one frame obtained by a de-framing processing section 26 directly with the coded ID data coded read from the ID memory 28 to detect the result as a regular ID data when the difference is less than a bit distance of the coded ID data or below and gives the detection output to a system controller 1. Thus, the ID data is confirmed without need of an error check decoding means or an error correction processing means. |
