Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows the configuration of a digital key telephone apparatus according to one embodiment of the present invention. As shown in the figure, the digital key telephone system 1, extension telephone _{3 (3 1, ..., 3} n) , which is key telephone system 2 and connected thereto with a. The key telephone main unit 2 mainly includes a switching circuit (TS
W) 4, control unit 5, line interface unit 6 (6 ₁ ,
..., 6 _m), the telephone interface unit 7 (7 _1, ...,
7 _n ). Between each line interface section 6 and the switching circuit (TSW) 4 and between the switching circuit (TS
W) 4 and each telephone interface unit 7 are connected by a voice highway, and each line interface unit 6, control unit 5, and each telephone interface unit 7 are connected by a data highway.

Each line interface unit 6 (6 ₁ ,...,
6 _m), the driver unit _{8 (8 1, ..., 8} m) and a processing unit _{(CPU) 9 (9 1,} ..., 9 m) having a processor (CP
U) 9 (9 ₁ ,..., 9 _m ) are RS232C ports 10 (10 ₁ ,.
0 _m ).

An RS232C port 10 of the line interface unit 6 has a PC (personal computer) serving as a status monitoring terminal.
Terminal 11 is connected.

The driver unit 8 of each line interface unit 6 is provided with an ISDN network 12 (or another IS (not shown)).
DN terminal).

In the key telephone main unit 2 of the digital key telephone unit 1 configured as described above, the line interface unit 6 communicates call processing data with the control unit 5 through the processing unit (CPU) 9. I have. The ISDN network 12 is connected to the layer 1, layer 2,
And digital communication of each layer of layer 3.
The processing unit (CPU) 9 transmits and receives Bch and Dch data to and from the driver unit 8 and controls the driver unit 8.

The processing unit (CPU) 9 has a function other than the above-described functions.
The PC terminal 11 connected to the RS232C port 10 sends out all transmitted and received data from the serial port.
, This can be displayed.

The transmission / reception data transmitted and displayed by the processing unit (CPU) 9 to the PC terminal 11 has conventionally only been exchanged with the control unit 5 and exchanged with the ISDN network 12, but in this embodiment, By inputting a command for displaying necessary register information inside the processing unit (CPU) 9 and register information of the driver unit 8 from the terminal 11, register information inside the processing unit (CPU) 9 and register information of the driver unit 8 are input. Are transmitted from the processing unit (CPU) 9 to the PC terminal 11 and displayed, so that the status of the ICs of these units can be monitored. By doing so, it is possible to precisely analyze the cause of the occurrence of a line failure by finely dividing it.

Further, by inputting a command relating to a hardware test from the PC terminal 11, the hardware can be checked. Therefore, it is possible to reliably determine whether the cause is hardware or software.

The operation of the processing section (CPU) 9 will be further described with reference to the flowchart shown in FIG.

The processing section (CPU) 9 determines whether or not a command has been input from the PC terminal 11 (step S21).
The following normal information is displayed (step S22). Information exchanged with the ISDN network 12, for example, Layer 1 information indicating whether the line is disconnected or not. Information exchanged between the processing unit (CPU) 9 and the control unit 5, for example, when the extension telephone 3 wants to make a call,
When the control unit 5 detects the call, the control unit 5 sets the processing unit (CP
U) Layer 2 and layer 3 information given to 9,
Alternatively, layer 2 and layer 3 information given to the control unit 5 by the processing unit (CPU) 9 detecting an incoming call.

On the other hand, it is determined whether or not a command for status monitoring has been input from the PC terminal 11 (step S21).
If there is an input of a status monitoring command, the command is identified (step S23), and the command is executed (step S24).

First, a case where a command for displaying register information in the processing unit (CPU) 9 or register information of the driver unit 8 is input as a status monitoring command will be described.

When the command C1 for displaying the register information of the driver unit 8 is input, the command is identified (step S23), and the command is executed to display the register information of the driver unit 8. (Step S24).

The registers of the driver section 8 include, for example, a register indicating an active state, a register indicating a frame state, a register indicating a clock state, and the like. Therefore,
From the display of these register information, it becomes easy to analyze the cause when a line failure occurs.

For example, the register indicating the active state is “1” when layer 1 is connected,
Is "0" when the frame has expired, and the register indicating the frame state is "1" when the frame is normal,
When the frame is abnormal, the value is "0". Accordingly, the following can be understood from the display of the active state register and the frame state register.

If the active state is "1" and the frame state is "1", there is no problem.

If the active state is "0" and the frame state is "1", there is a problem other than the frame.

If the active state is "1" and the frame state is "0", there is an error in the frame.

The register indicating the clock state is "1" when the clock from the ISDN 12 is normal, and "0" when the clock from the ISDN 12 is lost. Therefore, it can be determined from the display of the register indicating the clock state whether the clock from the ISDN 12 is normal.

When the command C2 for displaying the register information of the processing unit (CPU) 9 is input, the command C2 is identified (step S23), and the command is executed to execute the processing unit (CPU). 9.) Register information inside 9 is displayed (step S24).

The registers of the processing unit (CPU) 9 include:
For example, there is a register indicating information regarding that the processing unit (CPU) 9 has set the driver unit 8. That is, there are a register indicating a mode in which the processing unit (CPU) 9 has set the driver unit 8, a register indicating whether or not the setting is made to perform network synchronization, and the like.

Therefore, from the display of these registers, it is easy to analyze the cause of a system failure or the like.

For example, the register indicating the mode is ISD
The communication mode with the N network 12 is “1” when the communication mode is the NT mode, and “0” when the communication mode is the LT mode. Therefore, if the register indicating the mode indicates “0” despite the user having set the NT mode, the processing unit (CPU) 9
Indicates that the driver unit 8 has been set in the LT mode, which indicates that this is a system bug.

The register indicating whether or not the key telephone sets network synchronization of ISDN and CLK is "1" when the network synchronization is set, and "0" when the network synchronization is not set. When noise frequently occurs in communication,
Network synchronization may not be performed. In this case, if this register is set to "0" despite the fact that the user has set the network synchronization, it is known that the network synchronization is not set, which may be a system bug.

Next, a case where a command related to a hardware test is input as a status monitoring command will be described. For example, when the link with the ISDN network 12 is not established correctly, the driver unit 8
When a command H1 for performing a hardware check of the driver unit 8 is input in order to check whether the pulse shape issued to the CPU is a normal value, the processing unit (CPU)
9 identifies this command (step S2
3), executing this command, the driver unit 8 is set so as to emit only a predetermined pulse, and the PC terminal 11 displays that the command H1 is being executed (step S24). Then, the user can measure the value of the pulse output from the driver unit 8. And
For example, if the value is abnormal, it can be determined that the amplifier of the driver unit 8 is abnormal.

A command H for performing a loop-back process of having the data transmitted to the other terminal be sent back.
When 2 is input, the processing unit (CPU) 9 identifies this command (step S23), executes this command, and compares the data transmitted to the partner terminal with the data sent back from the partner terminal and received. By comparing and performing an error check and displaying the resulting error count (step S24), the hardware check of the partner terminal can be performed.

When a command is input from the PC terminal 11, a security function is provided so that the command is not valid until a predetermined password is input.
Safety shall also be considered so that operations that affect the system cannot be performed from the C port 10.

As described above, in this embodiment, in addition to the information on the exchange of data with the ISDN network 12 and the exchange with the control unit 5, the processing unit of the line interface unit 6 necessary for analysis when a problem occurs. (CPU) 9
In addition, since a command for displaying register information of the driver unit 8 is provided to monitor the state of the IC of each unit when a failure occurs, problem analysis can be performed more easily than in the past. . Further, since a command related to a hardware test is provided, it is possible to easily confirm a hardware failure.
