Abstract

PURPOSE: An emulating method in a switching system is provided to directly find out a main cause of a failure through an emulation process in the switching system without another emulator, so as to quickly find out the main cause. CONSTITUTION: If an 'enter key' is inputted from a PC, a switching system stores an inputted command in a buffer(102). The system decides whether the command is a break command(104). If so, the system uses an address inputted in a decoder to generate an interrupt, when the address is accessed subsequently(108). If the command is not the break command, the system decides whether the inputted command is a trace command(106). If so, the system uses the address of the decoder and sets up a trace flag of an optional buffer in a RAM, to present the trace command, then returns to a step of deciding whether the 'enter key' is inputted(100). If the command is not the trace command, the system decides whether the inputted command is a display command(112). If so, the system outputs an inputted address or a CPU register to a display, and returns to the step of deciding whether the 'enter key' is inputted. If the command is not the display command, the system displays an error message on the display and returns to the step of deciding whether the 'enter key' is inputted(116).

Description

Method for emulating exchange system

The present invention relates to an emulation method of an exchange system, and more particularly to an emulation method without using emulator equipment for emulating an exchange system.

Nowadays, not only products are sold to consumers, but also continuous management of the sold products, namely after-sales service, is also very important. Because from the consumer's point of view, if the price of the purchased product is high and low, and wants to provide after-sales service in case of product failure or other needs, the customer wants to be provided with prompt and friendly service. This is because the company's reliability is high as well as its reliability. As a result, companies that produce and sell products provide a competitive after-sale service with other companies and at the same time provide a thorough after-sales service that fulfills the responsibility for the products sold.

However, in the case of an exchange system such as a key phone system, a debugging device called an emulator is used to find the cause of the failure. Since the emulator device is bulky and other complicated equipment such as a workstation needs to be mobilized, it is necessary to request a customer's after-sales service. There is a problem that can not be satisfied 100%.

It is therefore an object of the present invention to provide an emulation method of an exchange system that can solve the above-mentioned conventional problems.

Another object of the present invention is to provide an emulation method for emulating an exchange system without using emulator equipment.

In order to achieve the above objects, the present invention provides a method for emulating a switching system, comprising: analyzing a command input through a personal communication device; And writing an address input to the decoder according to the analyzed command or displaying an error on a display screen.

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

1 is a block diagram of a key phone system 10 according to a preferred embodiment of the present invention. Referring to the drawing, the key system 10 is a decoder 14, program ROM 16, RAM 18, trunk line connection circuit 20, switching circuit 22, extension connection centering on the CPI (12) The circuit 24, the trunk line 26, and the station 28 are arranged, and the personal computer 32 is connected to the CPI 12 through the RS-232C 30. Here, the personal computer 32 performs a function of exchanging and receiving a decoder and trace command for specifying a trace address with the key phone system 10 which is a simple exchange system. The decoder 14 may input up to 100 addresses from one specific address.

In the key phone system 10 having the above-described configuration, the brake function, the trace function, the step function, and the display function which are made through the conventional emulator equipment are all made. Therefore, the keyphone system 10 has an advantage that can be quickly repaired because emulation is possible in the case of a failure of the keyphone system without using the emulator equipment that is not portable, there is an advantage in this repair process shown in Figures 2 to 4 It will be described with reference to the flow chart shown.

First, FIG. 2 is a flowchart illustrating a process of receiving a command from a personal computer.

Referring to the drawing, in step 100, it is determined whether the enter key has been entered from the personal computer 32 (or the general telephone) of FIG. 1, and when the enter key has not been entered, the process returns to step 100, and the enter key is If it is entered, it is recognized as a command and proceeds to step 102. In step 102, the input content is stored in a buffer, and then the process proceeds to step 104 where it is determined whether the content transmitted from step 102 is a break command. As a result of the determination, in the case of the break command, the flow proceeds to step 108 to write an address input to the decoder 14 so that an interrupt is applied when the address is later accessed. On the other hand, if it is not a break command, the process proceeds to step 106 and determines whether it is a trace command. Set the trace flag of the temporary buffer, and return to step 100. However, if it is not a trace command, the flow proceeds to step 112 and determines whether it is a display command. In the case of a display command, after outputting the input address or CPI register on the personal computer 32 screen, the process returns to step 100. . If it is not a display command, the flow proceeds to step 116 and displays an error on the monitor of the personal computer 32, and then returns to step 100.

As such, since the brake function, the trace function, the step function, and the display function are all performed inside the key phone system 10 according to the present invention, the key phone system 10 can be emulated without using emulator equipment that is difficult to carry and install. .

3 is a flowchart illustrating a process of processing an interrupt through the decoder 14. That is, the flowchart shown in FIG. 3 represents a process for processing an interrupt that occurs when an address input to the decoder 14 is accessed while a program is received and an instruction is executed.

Referring to the drawing, it is determined whether the emulator interrupt is interrupted in step 200. If the emulator interrupt is not interrupted, the process returns to step 200. If the emulator interrupt is interrupted, the process proceeds to step 202. The contents of the register and the contents used in the key system 10 are stored in a buffer and output to the monitor of the personal computer 32. Subsequently, in step 204, it is determined whether the trace flag is set. If the trace flag is set, the process proceeds to step 206. The step trace bit of the CPI 12 is turned on, and then the process returns to step 200. Goes. If the trace flag is not set, the process returns to step 200.

4 is a flow chart illustrating a process of processing a step trace interrupt. That is, this is a flowchart showing a process for processing a step trace interrupt when the trace bit of the CPI 12 is turned on.

Referring to the drawing, after determining whether the step trace interrupt has been performed in step 300, if the step trace interrupt is not received, the process returns to step 300; on the contrary, if the step trace interrupt is performed, the process proceeds to step 302 and the current instruction Is stored in a buffer inside the RAM 18 area. In step 304, it is determined whether the number of instructions stored in the buffer and the number of input instructions match. The stored contents are output to the monitor of the personal computer 32. If the number of stored commands does not match the number of input commands, the process returns to step 300 immediately.

Referring to the series of processes shown in Figures 2 to 4 as an example.

The brake function is used to know whether or not to read or write the 12000h address. In order to use the brake function, first, the comfort of the personal computer 32 is connected to the RS-232C (30) of the key phone system (10). After connecting to, press the Enter key and you will see the prompt "emul>". Since the method of receiving the input from the personal computer 32 may use one of several methods, it will not be described in detail herein. Then, after the break command, a specific address is input. For example, if "emul> break 12000h" is input, 12000h is written to the decoder 14 through the process of FIG. Therefore, when the program is executed or read or written to 12000h address, an interrupt is applied. In this case, the current contents are output to the monitor of the personal computer 32 through the process of FIG. 3.

Herein, the above-described command includes various commands as follows. For example, selecting "emul> break 12000h-12100h", 12000h, 13000h, or 19000h, which means that an interrupt occurs when you select one of addresses 12000h through 12100h, is "emul". Break 12000h, 13000h 19000h "em" trace 12000h counter 2000 "which means to save 2000 instructions after accessing 12000h," emul "means to execute and stop 10 instructions after the break command "Stop 10", "emul" display register "to display the current register contents after the break command.

As described above, according to the present invention, when a problem such as a failure occurs in the process of using the exchange system, since the cause of the failure is directly found through the emulation process of the exchange system itself without a separate emulator equipment, the failure occurs more quickly. There is an effect that can find the cause.
