Title: Fault diagnostic method for isdn terminal equipment and communication system
Inventor: FUJII TAKANORI
IPC: H04M3/22
Filed: 1993-02-01
Abstract: PURPOSE:To more surely report a fault by enabling the report even in the case of a light line defect by reporting the fault to a maintenance service center by using the D channel of an ISDN line. CONSTITUTION:When reporting the fault to the maintenance service center, a data terminal equipment 1a transmits report information corresponding to the user/user information of a call setting message 'SETUP'. In such a case, a call control message like the call setting message 'SETUP' is transmitted by using the D channel of the ISDN line. Since the bit rate of data transfer for the D channel is lower in comparison with a B channel and time slots on a frame signal are distributed, the data transfer is frequently enabled even in the case of the light line defect. Therefore, the fault can be more surely reported in comparison with the conventional case of reporting the fault by the B channel.
