摘要:
A test cell generating section periodically generates a pass determining test cell at preset timing, multiplexes them with user cells from a user line interface, and transmits the result of multiplexing to an ATM exchange. When no user cell is supplied from the user line interface, the test cell generating section transmits only the pass determining test cell to the ATM exchange. A cell determining section determines whether a cell supplied from the ATM exchange is a user cell or test cell, identifies/determines the pass based on information of the test cell and outputs only the user cell to the user line side when the supplied cell is the test cell.
