Abstract

PURPOSE: A method for yielding statistics and outputting trunk slip count in a full electronic telephone exchange is provided to prevent a slip phenomenon. CONSTITUTION: A remote office or a different switching system receives a clock through a trunk and transmits the clock to a network synchronization interfacing unit, and then receives a clock returning from the network synchronization interfacing unit and transmits it to the opposite switching system(202). The clock received from the opposite switching system and the clock transmitted to the opposite switching system are detected to check whether the transmitted clock and the received clock are identical(204). If the two clocks are identical, a signal is processed according to a normal signal processing procedure(206). If the clocks are not identical and a slop occurs, a line controlled is informed of occurrence of slip(208). The line controller by-passes a slip count data informed by a trunk interfacing unit to a main controller(210). The main controller stores the slip count data for the system failure informed by the line controller in a statistics database(212). The slip count data stored in the statistics data is periodically fetched to yield statistics(214). The main controller renders the slip count according to the statistics in the statistics database to be displayed through an input/output unit periodically.

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

The configuration of the present invention, the other exchange 100 that connects the call between the country or the country by transmitting and receiving signals to the power station or the country as an exchange, and the electronic switch 110 to disconnect the call between the subscribers, A relay line matching unit 112 for converting a signal input from a large station into a signal recognized by the local station, and a network synchronization matching unit 114 for generating a synchronization signal generated by itself in case of an unsynchronized signal and synchronizing the signal; When the call of the subscribers is input, the line control unit 116 connects the setup message from the subscribers and the signals between the own stations, and connects the subscribers through the power station to other stations, and the information received from the line control unit 116 is converted into a number translation unit ( The main control unit 118 for requesting the number translation and receiving the slip count from the line control unit 116 and storing the statistics in the statistics database; The statistics database 119 stores statistics resulting from sleep slip counts and other exchange information, and an input / output unit 120 that receives an operator's command and receives and outputs information from the exchange. .

Hereinafter, with reference to the accompanying drawings, it will be described in detail a preferred embodiment of the present invention.

Referring to FIG. 1, an electronic switch which is suitable for calculating and outputting relay slip count statistics is described. The other switch 100 transmits / receives signals to a power station as a private switch or an electronic switch, or as another switch. Connects calls between big and home countries,

In the case of a signal received from the outside, the electronic switchboard 110 receives a signal and synchronizes the signal to control the synchronized signal, thereby disconnecting or disconnecting a call between subscribers. There is no need to control the connection and disconnection.

The relay line matching unit 112 converts a signal input from a large station into a signal recognized by the own station. In the case of a signal going out of the large station, the relay line matching unit 112 converts the signal using a common line signal method and transmits the signal to the large station so that the exchange is connected.

The network synchronization matching unit 114 processes a signal received through the relay line matching unit 112 in a large station into a signal that can be processed internally, and compares the processed signal in a main processor to generate a synchronization in itself when the signal is not synchronized. By generating a signal to synchronize the signal to prevent the synchronization of the signal to prevent the slip occurs.

When the call of the subscriber is input, the line controller 116 transmits information such as setup message, digit information and device number from the subscriber, call connection request, call termination request, etc. The signal is connected, and the subscribers are connected to other stations through the power station, and the call is terminated under the control of the main controller 118. The main controller 118 requests a number translation from the information received from the line controller 116 to a number translation unit (not shown), disconnects the signal according to the received signal, and transmits information such as slip count data to the line control unit ( Received from 116 and stored in the statistics database 119 statistics.

The statistics database 119 stores the sleep count and the sleep count data in the main control unit 118 at the request of the main control unit 118, and stores the counts of the sleep data and the sleep data in the main control unit 118, and then calculates the statistics through the main control unit 118. The calculated information is periodically displayed to the operator through the input / output unit 120.

The input / output unit 120 receives the operator's command, performs the received command, informs the operator of alarm information and slip count of the exchange, periodically informs the operator of the operating state of the exchange, and operates other exchanges at the request of the operator. The status is displayed to the subscriber so that the operator can easily see the information of the exchange.

Referring to FIG. 2, a method for calculating and outputting relay line slip count statistics in an all-electronic switch is described. In a large station or another switch, a clock is received through a relay line and the clock received from the relay line is transmitted to the network synchronization matching unit 114. Then, the clock returned from the network synchronization matching unit 114 is received and transmitted to the counterpart exchange through the relay line (step 202).

At this time, the clock received at the counterpart exchange and the clock transmitted to the counterpart exchange are detected to determine whether the transmit clock and the receive clock match (step 204).

If the clock is determined in step 204, the signal is processed according to a normal signal processing procedure (step 206).

If it is determined in step 204 that the clock is inconsistent and slip occurs, the line control unit 116 notifies the sleep controller that the slip has occurred (step 208).

The line controller 116 bypasses the slip count data notified by the relay line matching unit 112 to the main controller 118 (step 210).

The main control unit 118 stores the count data of the slip occurrence for the system failure notified by the line control unit 116 in the statistical database 119 of the main control unit 118 (step 212).

Statistics are calculated by periodically taking sleep count data stored in the statistics database 119 (step 214).

The above-described period may be input and used by an operator through an input / output unit 120 through a man and machine communication (MMC) command, and the basic setting may be set for one period.

The main controller 118 periodically displays the sleep count calculated in the statistical database 119 to the input / output unit 120 (step 216).

As described above, the present invention detects the clock for each time slot in the relay board in the electronic switchboard in order to take an active countermeasure when slip occurs, and notify the line controller 116 when the input and output of the clock are different. In the statistics database 119 of the main control unit 118, statistics are calculated, and slip count statistics indicating the frequency of sleep counts for each time slot are displayed to prevent slip phenomenon.

The principles of the invention have been described above in connection with specific devices, which are described by way of example only, and are not limited to the spirit of the invention as described in the appended claims.
