Description

Stored-program control exchange centralized operation maintenance system

The present invention relates to a kind of Maintenance of Program Control Exchange system, relate to the centralized operation maintenance system of stored-program control exchange or rather.

Stored-program control exchange is a kind ofly various execution units to be controlled by the software program of setting by special-purpose computer or all kinds of processor, the electronic switching system (ESS) that finish call, continues, except possessing main telecommunications function of exchange, also can safeguard himself, but because switch itself does not possess information reprocessing ability, therefore can only be with every performance of safeguarding, provide to the operator with man-machine interaction mode by operating terminal as switch operation information, operating state etc., it is implemented control by the operator.

At present, the regular maintenance of national exchange system mostly adopts the unit dispersing mode, it is a kind of maintenance management mode of guarding formula, finish through attendant's craft or through the simple process of microcomputer, promptly send audible, visual alarm signal by the alarm panel of switch, remind operating personnel to note, the running status that operating personnel inquire about switch by the operation control terminal again, find its concrete guilty culprit, then adopt suitable control command to handle, the final fault of eliminating safeguards that switch runs well.

In addition, the line service of switch also comprises routine test, modification office configuration data and to the operation information classification of switches such as telephone traffic, fault, alarm, statistics etc.

Development along with telecommunications, the capacity of digital communication equipment such as stored-program control exchange constantly increases, proposed renewal, higher requirement also for the maintenance management work of equipment, the maintenance management mode and the means of distributing, guard's formula far can not adapt with it, have only " interaction " that had according to the digitlization switching equipment to reach the technical characterictic of " monitoring property ", adopt advanced information processing and control device can comply with the needs of modernized communication network development to its maintenance management of carrying out centralization.In addition, have only the maintenance management mode that adopts centralization just can make few in number, have that high-caliber maintenance management personnel obtain fully, reasonably use, thereby improve the whole maintenance management level of the whole network, and make all devices obtain safe, effective and high-quality control.
