<P>PROBLEM TO BE SOLVED: To provide a system and method for determining data error of an optical network facility where the existence/non-existence of data error is automatically determined, by combining the result of light-receiving level confirmation test and the result of an optical network unit (ONU) state confirmation test, with respect to an ONU. <P>SOLUTION: On the basis of identification information of an optical core wire accumulated in a facility DB 110, a light-receiving level confirmation test function section 120 confirms presence/absence of received light from an ONU connected to the optical core wire for each optical core wire and on the basis of the identification information of the ONU accumulated in the facility DB 110, an ONU state confirmation test function section 130 confirms a state of the ONU connected to the optical core wire. Furthermore, a data error determination function section 140 compares a determination table with a confirmation result of the light-receiving level confirmation test function section 120 and a confirmation result of the ONU state confirmation test function section 130, determines the existence/non-existence of errors in connection information accumulated in the facility DB 110, and outputs the result of the determination. <P>COPYRIGHT: (C)2009,JPO&INPIT |
