Abstract

PURPOSE:To realize the qualification of the normality of an integrated service digital network(ISDN) switching system and specification of a device in which abnormality is generated, by displaying a response signal with respect to a test call received via a monitor line, etc., on a test device which constitutes the ISDN switching system. CONSTITUTION:For example, the test device 1 issues a packet call by a line 10 to be tested, and it is inputted as an incoming call at a dedicated test line 20 via an ISDN line switching device 4, etc. At this time, the response signal such as a call control signal, a voice, data, and a packet received at the line 10 and the line 20, and the call control signal, the voice, the data, and the packet, etc., received at the monitor lines 31-33 are displayed on the display device of the device 1, and the presence/absence of the abnormality is checked. When the abnormality is found, the call control signal, the voice, the data, and the packet of each part are qualified, then, the device in which the abnormality is generated can be discriminated.
