KR940013057A - Maintenance management system of system with multi-level tandem structure for remote information processing - Google Patents

Abstract

The present invention relates to a system having a multi-stage tandem structure for processing remote information by using a telephone line of an exchange office. In particular, it is possible to quickly detect a failure occurring in a multi-stage tandem structured system that is separated from each stage in a modular area, and to maintain reasonable maintenance management. It relates to a maintenance management device that facilitates.

The maintenance management device detects a failure state generated in a line multiple access device and a line polling machine located in an exchange station, and maintains and manages the detected failure message by the central computer as a whole and communicates with the central computer. To the device.

By the above operation, the central computer can quickly detect the failure state occurring in each module remotely from the region, and the central computer centrally manages the failure state and redistributes it to the maintenance management device of the corresponding telephone company. Reasonable maintenance can be facilitated.
