<p><P>PROBLEM TO BE SOLVED: To provide a cell continuity inspection system by which an ATM tester is connected to a plurality of devices to be tested and simultaneously inspected, an inspection time for the ATM cell continuity inspection is shortened, and the inspection of a plurality of the devices to be tested can be executed in real time without enlarging a circuit scale of the device to be tested. <P>SOLUTION: The devices (A-C)2-1 to 2-3 are respectively cascaded to the ATM tester 1 via transmission path cables 100-103, and execute the transmission of an ATM cell for testing. A cell comparator 3 compares a cell transmitted from the ATM tester 1, a cell received by the ATM tester 1, and cells respectively subjected to monitor output toward the cell comparator 3 from respective cell monitors (A-C)21-1 to 21-3 of the devices (A-C)2-1 to 2-3 with a cell comparison inspection part 32 of the cell comparator 3 in real time; and determines the identity of the ATM cell for testing. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
