Abstract:
An OAM processing method in a plural-line terminating apparatus for accommodating a plurality of lines, converting signals from these plurality of lines to cells and sending the cells to a switch, sending cells from the switch to lines upon converting the cells to line signals, and executing OAM processing of the plurality of lines, said method comprising the steps of:multiplexing cells onto a cell stream after signals which enter from each of the lines are converted to the cells, and adding onto a cell header of each cell a line identifier that specifies the line on which this cell arrived;converting a combined identifier, which is a combination of the line identifier and a cell connection identifier that have been added onto a cell, to an internal-processing identifier and sending the cell having the internal-processing identifier to the switch side;unitarily managing data, which is necessary for OAM processing of each line, by a first management table using the internal-processing identifier as an address;reading data from said first management table based upon the internal-processing identifier of a cell received from each line; andexecuting OAM processing conforming to each line using the data that has been read.
