FAULT ANALYSIS DEVICE, FAULT ANALYSIS SYSTEM, FAULT ANALYSIS METHOD, AND PROGRAM FOR FAULT ANALYSIS

摘要

PROBLEM TO BE SOLVED: To provide a fault analysis device which easily detects the occurrence of a network fault having a possibility of hindrance to voice communication, so as to promptly recover from the fault.;SOLUTION: The fault analysis device includes: RTP packet generation means which generates an RTP packet; DTMF signal addition means which adds a DTMF signal to the RTP packet to be used as a fault detection signal; transmission means which transmits the fault detection signal to another fault analysis device; reception means which receives the fault detection signal returned from the other fault analysis device; problem detection means which detects a problematic module in the fault analysis device on the basis of the DTMF signal included in the fault detection signal received by the reception means; and reboot means which reboots the problematic module detected by the problem detection means.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2017,JPO&INPIT
