Abstract
In a method of executing OAM processing in a plural-line terminating apparatus, a physical layer terminator converts a line signal to cells and adds a line identifier onto each cell header, the identifier specifying the line on which the cell arrived. A header converter converts a line-identifier/VPI/VCI of each cell to an identifier ICID for internal processing. An OAM processor unitarily manages data, which is necessary for OAM processing of each line, by a connection management table using the internal-processing identifier as an address, reads data from the management table based upon the ICID of the cells received from each of the lines, and executes OAM processing conforming to each line using the data that has been read.
