It is about management devices.

Provides public switched telephone network (PSTN) or integrated service digital network (ISDN) service of the user Fortran subscriber station in the conventional V5.2 interface. It means a physical port that the subscriber line is terminated. This user port has logical protocol status information in addition to the line termination function as a physical port.

The protocol status information of the PSTN user port providing the PSTN service is managed in the PSTN protocol, and the status information is as follows. The AN0 state is inactive, the AN1 state is idle, the AN2 state is a path initiation state initiated by the subscriber station, the AN3 state is a path abandonment state, the AN4 state is a line information state, the AN5 state is a path active state, and the AN6 state is a port state. The blocking state and the AN7 state are call release request state information.

ISDN user port that provides ISDN-BRI (Integrated Service Digital Network-Basic Rate Interface) service is a port where digital line of ISDN-BRI service is terminated and is managed by port control protocol. Status information is as follows. The AN1.0 state is the port blocking state, the AN1.1 state is the country blocking release state, the AN1.2 state is the state blocking release state, the AN2.0 state is the operating state, the AN2.1 state is the activation request state, and AN2.2. The state is an access enabled state.

The state information of the PSTN or ISDN user port described above is changed by the call processing requested from the subscriber side or from the network side and the user port blocking / release of the port by the operator, and is managed by the protocol processing unit. The user port state information is managed only in the transition view of the protocol according to the call processing, and does not include various operational information that may actually occur in the subscriber transmission apparatus. It is not possible to determine the exact status of whether the disabled or operational error occurred in the V5 protocol itself, the reason for the blocking, or whether the unit that accommodated the user port has been dismounted. In addition, information that can be managed to operate the system, such as fault location search and accurate operation status information of the system, may appear in various ways depending on the failure management or performance management prescribed for each system.

Therefore, the state information of the user port according to the conventional protocol viewpoint is simply defined in terms of the efficiency of the operational capability, so that it is difficult to take the subscriber failure recovery action or the proper operation action only by the above state information, and thus provide sufficient information. In order to solve the problem, it is necessary to check other fault information prescribed in the subscriber transmission system.

The present invention has been made to solve the above-mentioned drawbacks of the prior art, and in addition to the protocol status information of the user port prescribed in the V5.2 interface standard, the user port state management is specified in detail in terms of operation, and the failure of the subscriber line. User port status of the subscriber station with V5.2 interface that enhances the operational capability of the subscriber station and the location of the fault location by first checking this operational status information and determining the next operational action procedure during recovery. The purpose is to provide a management device.

In order to achieve the above object, the present invention provides a user port state management apparatus of a subscriber transmitter connected to a switch having a V5.2 interface, and manages protocol state information related to a PSTN / ISDN user port of the subscriber transmitter. A protocol processing unit; And operation state information of the PSTN user port, operation state information of the ISDN user port, and system operation state information of the subscriber transmission device based on the protocol state information and system failure related information generated in the subscriber transmission device. It characterized in that it comprises a system management unit that prescribes the detailed operation status information.

Hereinafter, an embodiment of the present invention for achieving the above object in detail.

FIG. 1 is a block diagram showing an embodiment of a user port state management apparatus of a subscriber transmission apparatus having a V5.2 interface according to the present invention, and is comprised of a digital electronic switch 1 and a subscriber transmission apparatus 2.
