Since the storage medium developed for the CCU is expensive, the CCU usually does not have a large-capacity storage medium and a program for controlling communication is stored. And, it has only the minimum required capacity as a memory for executing the program. Further, since the CCU needs to be mounted in a predetermined slot, the external dimensions of the board are determined.
Therefore, it is practically impossible to mount a large amount of storage medium in the limited mounting area of the board. For this reason, since the CCU has a small capacity of the storage medium, the CCU cannot save the fault data necessary for the analysis of the line fault etc. by itself, and a lot of man-hours are spent for the fault analysis.

BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of a line control device, a line control method and a storage medium storing a program according to the present invention will be described in detail below with reference to the drawings.

In the present embodiment, as described above, the board is usually not yet mounted on the slot in the cage,
To provide a recording medium accessible from a plurality of CCUs, and for this memory control, as a function of a memory control circuit of a CCU that has existed in the past, a function of accessing a storage device outside the CCU is newly added. It is characterized by that.

That is, as shown in FIG.
By adding the memory control circuits 71 to 73 in 3 and providing the dedicated storage medium 31 in the empty slot 81 of the cage 51, without changing the conventional cage 51,
It is possible to store a large amount of fault data.

FIG. 1 is a block diagram showing an embodiment of the present invention. In FIG. 1, the host 61 and each CCU
41 to 43 are connected via COPs 11 to 13 in each CCU. CCU has multiple Ls per COP
Since it is possible to control A, L under COP
A plurality of A are mounted side by side in the cage 51.

Here, for the sake of easy understanding, the CCU is used.
41 is COP11 + LA21 + LA22, CCU42
Shows a case where COP12 + LA23 + LA24 is mounted, and CCU43 mounts COP13 + LA25. At this time, the unmounted area of the board that normally exists is set as an empty slot. Further, the cage 51 is provided with a back panel 70 for transmitting and receiving signals between the COP and the LA. Further, each LA controls the lines # 0 to # 4.

The feature of this embodiment is that the storage medium 51 accessible from a plurality of CCUs is provided in the slot 81 as described above. Further, as a function of controlling the storage medium 51, memory control circuits 71 to 73 are provided on the COPs 11 to 13, respectively. This is a function added to the memory control function that the CCU has conventionally provided for program control.

Next, the operation will be described with reference to the flowchart of FIG. Here, as an example that is effective in explaining the present invention, a case where a failure occurs in the line # 2 in FIG. 1 will be described in detail with reference to FIGS. 1 and 2. When a failure occurs on the line # 2 (T1), the LA 23 detects the failure on the line and requests an interrupt to the COP 12 (T1).
2). The COP 12 confirms the cause of the interrupt from the LA 23 and determines whether the interrupt is a line fault (T
3).

When the COP 12 determines that it is a line fault, it raises an interrupt from the memory control circuit 72 to the storage medium 31 (T4). If the storage medium 31 is not under control of another COP at that time, it returns an acknowledge signal for the interrupt to the memory control circuit 72,
The master right of the storage medium 31 is entrusted to the COP 12 (T5).
The COP 12 transfers the fault data to the storage medium 31. The storage medium 31 stores the data (T6).

The storage medium storing the program for executing the process shown in the flowchart of FIG. 2 performed in each COP constitutes the present invention.

At the time of failure analysis, by software operation,
The host 61 makes a fault data request to the COP 12. The COP 12 receives the storage medium 3 from the memory control circuit 72.
Make a master request to 1. In response to the request, the storage medium 31 returns an acknowledge signal to the memory control circuit 72. C
The OP 12 reads the fault data from the storage medium 31 and transfers it to the host 61.

According to the present embodiment, by using a slot that is usually not mounted yet and sharing a fault data storage area for a plurality of lines,
There are advantages in terms of implementation and cost. Therefore, with the minimum implementation and development costs, it is possible to reduce the burden of analysis and investigation, which has conventionally required a great number of man-hours in the event of a line failure.

Next, a second embodiment of the present invention will be described. As a terminal device connected to the public line, the CCU also defines the voltage level of the line signal and the undershoot / overshoot level of the clock signal as a standard for connecting to the public line.

According to the present invention, the output signal pattern to the public line, which is required in the series of quality tests as shown in the preceding paragraph, is stored as a program in the storage medium in advance, so that the program can be easily performed. The signal control is made possible.

FIG. 3 is a block diagram showing an embodiment of the above invention. In FIG. 3, the storage medium 106 is mounted in the slot 108, which is an empty slot in the cage 100, and the ROM 10 is provided inside the storage medium 106.
7 is provided. This ROM 107 has LAs 104, 105
A program for controlling the output signals from the lines to the lines # 10 and # 11 is stored.

Further, the COP 103 has a touch panel 10
1 is set. When the touch panel 101 is manually pressed, the memory control circuit 102 causes the ROM 1 of the storage medium 106 to move.
Read a certain program data with 07 area.
The COP 103 can output the test signal to the lines # 10 and # 11 via the LAs 104 and 105 under the COP 103 by executing the read program.

According to the present embodiment, since the output signal control to the line can be performed without using the host machine in the line qualification test required when exporting the device, the CCU excluding the host during the qualification test is used. Also, testing can be performed with only the configuration of peripheral devices (casing, power supply, etc.).

A ROM storing a program showing the signal pattern for the test used in the line qualification test.
107 constitutes the storage medium according to the present invention.
