Driver 25 for switching the switching elements of the sensing unit, the sensing unit for detecting when the switching elements switched by the driver to communicate with the base station B (130,230) receives and transmits the status information of the base station B (130,230) ( 27), the control unit 23 for receiving a signal for the status information of the base station from the detection unit 27 that detects the status information of the base station B (30,230), and the state information for the base station B (130,230) from the control unit 23 Phone line after receiving The base station B (130,230) to compare the status signal of the base station B (130,230) detected by the wired transmitter 28 and the detector 27 for transmitting the status information to the switch 210 connected to the base station B (130,230) by using the It comprises a memory 24 for storing predetermined characteristic data for each component of the.

Next, the operation process of the base station remote control and recovery apparatus shown in Figure 2, first, when the detection unit 27 receives the status information of the base station B (130,230), the control unit 13, 23 signal for comparison data request Send it. Upon receiving the comparison data request signal, the controllers 13 and 23 call the comparison data from the memory 24 and send the comparison data to the sensing unit 27 to compare and determine whether there is an abnormality among the components of the base stations B 130 and 230. This determination process may be performed by the controllers 13 and 23.

Here, the terminal unit (16, 26) is composed of a plurality of switch elements, has a switching function selectively in accordance with the call message received by the wireless transmission and reception unit (11, 21), according to the on-off operation of the switch By alternately configuring the closed circuit and the open circuit by a wired cable connected to the switch (110, 210), and transmits the control and recovery signal to the base station B (130,230), the status information of each component configured in the base station B (130,230), It is characterized in that it is configured to receive the current, voltage, contacts, data and the like and transmit it to the sensing unit.

That is, the terminal parts 16 and 26 are composed of switching elements, and the switching elements are relays 16a and 26a having a switching function, and magnet switches 16b and 26b requiring a large current. , SSR (Solid-state relay) (16c, 26c), transistor type switches (16d, 26d) and various types of switches (16e, 26e) are used, and suitable switch according to the capacity and line conditions or specifications required for driving Use a combination of several or several types of switches.

3 shows a schematic diagram of loopback switches 16e and 26e configured in RRS 100 and 200 that are switched to perform loopback tests on the line between the exchange and the base station.

Referring to Figure 3 describes the process of performing a loop-back (loop-back) test using a wireless network by the loopback switch (16e, 26e) as follows.

First, the RRSs 100 and 200 of the present invention are connected and installed to the telephone line input unit 53 in the base station 52. At this time, the loopback switches 16e and 26e in the terminal section of the remote control and recovery apparatus and the telephone line input unit 53 are connected.

The telephone line input unit 53 may be a line which checks whether there is an abnormality in a regular line, or may be a line having a problem.

That is, normally, the A output terminal of the switch 51 is connected with the a input terminal of the telephone line input unit 53, and the B output terminal of the switch 51 is connected with the b input terminal of the telephone line input line 53.

As described above, when the external base station 52 transmits a radio signal, the radio signal is received by the radio transmitter / receiver units 11 and 21 of the RRSs 100 and 200 installed in the base station to be inspected, and the codec units 12 and 22 are used. And analyzing the message of the specific number through the control unit (13, 23), the switch is switched among the switches mounted in the terminal unit (16, 26) via the drive unit (15, 25) to transmit a control and recovery signal to the base station And receive data from the base station. Since it is assumed here that the loopback test is performed, when the wireless transceiver configured in the RRS receives a signal for the loopback test, it is decoded by the codecs 12 and 22 and transmitted to the control units 13 and 23. Upon receiving the loopback test signal, the controllers 13 and 23 transmit the received signal back to the drivers 15 and 25. The driving units 15 and 25 then switch the loopback switches 16e and 26e configured in the terminal units 16 and 26. When the loopback switches 16e and 26e are switched, the A and B output terminals of the exchanger 51 switch the loopback switches 16e and 26e of the terminal parts 6 and 26 while switching the a, B, and A of the telephone line line input unit 53. b is disconnected from the input terminal and connected to the a 'and b' output terminals of the exchanger 51, and the signal input from the exchanger 51 is returned to the exchanger again by the loopback switch of the RRS installed in the base station B (130, 230). A loop constituting the loop is formed.

Next, when a specific number message is received by the radio signal, the A and B output terminals of the switch 51 are restored to the loopback switches 16e and 26e of the terminal units 16 and 26, and the telephone line input unit 53 It is connected to a and b input terminal again.

Therefore, when a loop formed of the above closed loop is formed, the switch 51 transmits a predetermined signal, and the signal returned to the switch 51 by the loop is compared with the signal transmitted, thereby causing problems on the line. You will know. That is, if there is a problem such as bit error, synchronization error, signal reception, etc., the position of the line and equipment illustrated on the monitor is displayed. If there is no problem on the line and equipment, it is a problem of the exchange 51 or the base station 52 itself. The scope of inspection is reduced.

Therefore, the abnormality of the line and the equipment between the base station and the exchange can be confirmed quickly and accurately, and various switching devices can be controlled to analyze the problem in various ways.

The above-described input message is an example of a preset message value for loopback switching to the RRS. When the RRS receives the above-described input value, the loopback switches 16e and 26e are switched to form a loop or release the loop. It is possible to determine whether there is an abnormality in the line by comparing the signal returned from the exchange by transmitting the characteristic signal from the switch to the looped line and the initial transmitted signal.
