Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of an operator radio paging device when a RASM emergency occurs in a TDX-100 exchange according to an embodiment of the present invention. The embodiment of the present invention includes an ASS, an INS, and a CCS, A host 10 for performing an overall call processing operation on the subscriber and controlling the operation of the RASM 20 by transmitting a predetermined IPC message to the RASM 20, The RASM 20, the pager lower end 26 and the pager lower end 26 connected to the other exchanger 30 through the pager lower end 26, And translates the called number based on a digit signal transmitted from the RASM 20 through the RASM 20. The pager corresponding to the called number is transmitted through the pager network 40 Another exchange 30 for making a call, A pager network 40 for transmitting a paging signal to a pager corresponding to a called number transmitted from the pager 30 and a pager 40 for receiving a paging signal transmitted through the pager network 40 And the phasors P1-Pn.

1, the RASM 20 is connected to the host 10 through an E1 PCM cable or an optical link cable and connected to the host 10 via the E1 PCM cable or an optical link cable, And a main processor RASP 23 such as a device such as the RI 21 and the TSW 24 phaser matching terminal 26 and the like A TP 22 for performing an interface function between the main processor and the device, and a TP 22 connected to the TP 22 to perform an overall call processing function, an operation and maintenance function in the RASM 20, A RASP 23 as a main processor for performing a control function of a peripheral device of the terminal 20, a TSW 24 for performing an interchanger function of a time slot under the control of the TP 22, Under the control of the TP 22, An ASI 25 that performs an interface function for the TP 22 and a phaser matching terminal 26 that performs a connection function to the wireless call alternator 30 under the control of the TP 22.

Here, the RI 21 detects a failure condition due to a link cable failure, a link interface board failure, a transmission equipment failure, an IPC communication failure, etc., and reports the detected failure information to the RASP 23 via the TP 22 The RASP 23 sequentially stores the paging number stored in the RAS 23 when the failure information transmitted from the RI 21 is emergency information, To the other exchanger (30). The other exchanger 30 performs a call processing function so that a pager corresponding to the paging number transmitted from the pager matching terminal 26 can be called through the payer network 40.

Hereinafter, a method for paging an operator when a RASM emergency occurs in a TDX-100 switchboard according to an embodiment of the present invention will be described in detail with reference to a flowchart shown in FIG.

First, if a failure of a link cable, a link interface, a transmission equipment, an IPC communication, or the like is detected through the RI 21 or a power failure or network synchronization failure state is detected through an arbitrary device, The fault information is transmitted to the RASP 23 through the TP 22 and an alarm according to the fault information is collected in the RASP 23 in step 52.

If the alarm is not an emergency alarm (NO in step 54), that is, if the alarm is a main alarm or a general alarm, the RASP 23 determines whether the alarm is an emergency alarm (23) transmits the alarm to the host (10) through the TP (22) and the RI (21). Then, the host 10 judges the fault condition generated in the RASM 20 based on the alarm, and outputs a visible alarm and an audible alarm according to the main alarm or the general alarm through the alarm panel, (Step 56) so as to recognize the fault condition generated in the RASP 23.

However, if it is determined in step 54 that the alarm collected in step 52 in the RASP 23 is an emergency alarm (YES in step 54), the RASP 23 notifies the RAS 21 via the TP 22 and RI 21 And transmits an alarm to the host (10). The host 10 determines a failure state generated in the RASM 20 based on the alarm and outputs a visual alarm and an audible alarm according to the emergency alarm through the alarm panel, (Step 58) so as to recognize the state in which the emergency failure has occurred in the server 23.

Then, the RASP 23 translates the first call number among the stored call numbers (step 60), and transmits a digit signal corresponding to the translated call number to the phaser matching terminal 26 through the TP 22, Lt; / RTI > The corresponding digit signal transmitted to the phaser matching stage 26 is transmitted to the other exchanger 30 via its phaser matching stage 26 (step 62).

The other exchange 30 translates the called number based on the digit signal and wirelessly calls the paging subscriber corresponding to the called number, i.e., the first pager P1 through the pager network 40 (step 64) .

Meanwhile, the RASP 23 transmits a digit signal corresponding to the translated calling number to the other exchanger through the phaser matching terminal 26, and then monitors whether the alarm generated in step 50 is released (step 66) , The RASP 23 determines whether or not the fault element is released by the first operator carrying the first pager P1 receiving the paging signal for the alarm generated in step 50 A series of operation processes are terminated and the operation returns to the initial state.

However, if it is determined in step 66 that the alarm generated in step 50 is not released (NO in step 66), the RASP 23 determines whether a predetermined time, for example, five minutes has elapsed based on predetermined time data provided from the built- (Step 68). If it is determined in step 68 that the alarm has not been released (YES in step 68), the RASP 23 transmits a digit signal corresponding to the translated calling number to the TP 22 via the TP 22 It is determined whether the number of times of transmission to the phaser matching terminal 26 has reached a preset number of times, for example, three times (step 70).

The number of times that the RASP 23 transmits the digit signal to the phaser matching terminal 26 through the TP 22 is determined by the number of times that the other exchange 30 receives the digit signal and transmits the digit signal through the phaser network 40 Is equal to the number of times the pager has been called by the paging subscriber corresponding to the called number for that digit.

If it is determined in step 70 that the number of times that the RASP 23 has transmitted the call number to the phaser matching terminal 26 through the TP 22 has not reached three times NO), that is, when the number of times that the RASP 23 transmits the call number to the phaser matching terminal 26 through the TP 22 is less than three, the RASP 23 proceeds to step 62, The first pager P1 corresponding to the calling number is called in a wireless manner so that the first pager P1 can transmit an emergency failure to the RASM 20 So that a ringing tone or a vibration sound for notifying the generated state is continuously output.

On the contrary, if it is determined in step 70 that the number of times the RASP 23 has transmitted the call number to the phaser matching terminal 26 via the TP 22 has reached three times (YES in step 70) The RASP 22 proceeds to step 60 to translate the second calling number out of the stored calling numbers and transmits a digipe signal corresponding to the translated calling number to the phaser matching terminal 26 through the TP 22 So that the above-described operations from step 62 to step 70 are repeatedly performed.

Thereafter, the second pager P2 corresponding to the second paging number is called a predetermined number of times and the second operator is notified of the occurrence of the emergency failure in the RASM 20, but the alarm generated in step 50 is not released The RASP 23 sequentially translates the stored call number up to the n-th call number, and calls the n-th pager Pn corresponding to the n-th call number a predetermined number of times, To be notified of the occurrence of the emergency failure.

Then, after the n-th pager Pn corresponding to the n-th calling number is called a predetermined number of times and the n-th operator is alerted to the occurrence of the emergency failure in the RASM 20, The RASP 23 re-translates the first call number out of the pre-stored call numbers and sends a digit signal according to the call number to the phaser matching end 26 via the TP 22, Thereby allowing the operation to be performed again.

As described above, according to the apparatus and method for paging an operator when a RASM emergency occurs in the TDX-100 switchboard according to an embodiment of the present invention, when an emergency failure occurs in the RASM, An alert is displayed through the pager network and a specific pager is wirelessly called through the pager network to inform the operator of the RASM wearing the pager that the emergency of the RASM has occurred.

Accordingly, since the emergency occurrence status of the RASM can be confirmed quickly even when the operator leaves the operating station, the time required for repairing the RASM is shortened due to quick follow-up action for the failure generated in the RASM, By returning to the normal state, a high quality call service can be provided to the subscriber connected to the RASM.
