How to Maintain Subscribers' Terminals in Switches and Broadband Terminals in Broadband Integrated Information Network

摘要

The present invention relates to a method for maintaining a subscriber terminal in an exchange and a broadband network terminating apparatus in a broadband integrated information communication network, in which a B-NT connected to an ATM PVC switch applied to a broadband integrated information network performs a switching function for a virtual path When receiving the VP_AIS message from the B-NT in the subscriber terminal maintenance method of the ATM PVC exchanger, updates the failure management table and transmits the VP_AIS message to another ATM PVC exchange located on the virtual path connection A first step (120 to 124) of transmitting a VP_RDI message to the B-NT when the terminal is an end point on the virtual path, and outputting a failure to the specific subscriber terminal as an operator terminal; A second step (125-127) of receiving the VP_RDI message from another ATM PVC switch located on the virtual path and recording this fact in the failure management table and transmitting the VP_RDI message to the B-NT; And a third step (128 to 130) of searching status information on the failure management table and outputting the status information to the operator terminal when the operator requests status information on the subscriber terminal, A method of maintaining an end terminal in a subscriber terminal, the method comprising: transmitting a terminal location information of a VP_AIS message to an ATM PVC exchange when a failure is detected in a subscriber terminal connected to the terminal, A first step (131-134) of outputting a message to an operator terminal; And a second step (135,136) of recording the VP_RDI message in the failure management table when receiving the VP_RDI message from the ATM PVC switch, the maintenance cost of the ATM PVC switch can be reduced by performing the maintenance of the subscriber terminal in real time , The reliability of the communication network can be increased, and the quality of the information communication service provided to the subscriber can be improved.
