DISCLOSURE OF INVENTION Problems to be Solved by the Invention The conventional communication control processing device constructed by the above-mentioned shared line corresponding part wiring board system is provided with a line corresponding part L in accordance with accommodation of a low speed line.
When the mounting area for S is secured, it becomes necessary to secure an unnecessary mounting area for the line support unit LS for the high-speed line, and the line support unit LS is accommodated to accommodate the high-speed line.
If the mounting area for the low-speed line is secured, the accommodation of the low-speed line will be limited in terms of mounting regardless of the performance of the communication scanner unit CS, and in order to increase the accommodation of the low-speed line, a separate line-corresponding section wiring board is required. There is a problem that becomes.

Further, the communication control processing device according to the prior art constituted by the dedicated line corresponding part wiring board system has a high mounting efficiency for accommodating both the low speed line and the high speed line, but the low speed line and the high speed line are accommodated. Even if the lines cannot be mixed and accommodated, and if the number of low-speed lines and the number of high-speed lines each are small, separate line-corresponding wiring boards are required, resulting in a large amount of waste. I have a problem.

That is, the above-mentioned conventional technique has the above-mentioned problems, so that it is difficult to miniaturize the device and the cost performance is poor.

An object of the present invention is to solve the above-mentioned problems of the prior art, to fully utilize the performance of the communication scanner unit (line control processor) for both low speed lines and high speed lines, and to achieve excellent cost performance. It is to provide a communication control processing device capable of accommodating a line.

According to the present invention, the above-mentioned object is that the number of lines accommodated per line control processor (positioned the same as the communication scanner unit in the prior art) is in terms of the performance of the line control processor. Focusing on the fact that the number of high-speed lines is small and the number of low-speed lines is large, a plurality of line control processors, for example, first and second line control processors, and a plurality of line corresponding unit groups, for example, first and second
Of the first line control processor is mounted on the same wiring board, and the control signal of the first line control processor corresponds to the first line control unit and the control signal of the second line control processor corresponds to the second line. By connecting to each group independently, the line corresponding parts of each group are independently controlled, and by installing the line expansion wiring board instead of the second line control processor. , The control signal of the first line control processor is the first via the line expansion wiring board.
It is achieved by being connected to both the line interface units of and the second line interface units so that the line interface units of both groups are commonly controlled by the first line control processor.

[0021]

In consideration of the performance of the line control processor, the first and second line handling units each have a line handling unit LS that is about half the performance of the line control processor in the case of a low speed line.
In the case of a high-speed line, an area where the line interface LS corresponding to the performance of the line control processor can be mounted is prepared.

Thus, for accommodating high-speed lines,
The line corresponding units LS for high-speed lines are mounted on the first and second line corresponding units, and the respective line corresponding units are controlled by the first and second line control processors. In this case, in the first and second line interface units, the line interface LS for high-speed lines corresponding to the performance of the line control processor is used.
Since the mounting area is prepared, the performance of the line control processor can be fully utilized.

For accommodating the low-speed line, the line-corresponding unit LS for the low-speed line is mounted on the first and second line-corresponding unit groups, and the line expansion is performed instead of the second line control processor. A wiring board is mounted. As a result, the control signal of the first line control processor can be connected to both the first line control unit group and the second line control unit group via this line expansion wiring board, and one line control processor is provided. On the other hand, the number of line interface units LS that can be controlled by one unit can be expanded. As a result, it is possible to accommodate a large number of low speed lines by fully utilizing the performance of the line control processor without mounting two line control processors.

According to the communication control processing device of the present invention, it is possible to accommodate a line which makes full use of the performance of the line control processor for accommodating a high-speed line and a low-speed line. It is possible to easily accommodate lines with excellent performance.

The control processor 2 controls each of the line corresponding units 2a to 2d of the second line corresponding unit group by the second line corresponding unit control signal group 2e wired on the line control unit wiring board 4. The first line interface control signal group 1e is also connected to the mounting position of the second line control processor 2 on the line controller wiring board 4. This line control processor 2
The unused terminal of the line control processor 2 is selected as the mounting position of the first line corresponding part control signal group 1e for.

In the above description, the number of line interface units of each group is set to a number that can fully utilize the capability of the line control processor for controlling the line interface units of each group.

According to the embodiment of the present invention shown in FIG. 1 described above, two sets of line control processors can control four sets of line corresponding units respectively accommodating high-speed lines, all of which can be controlled. It can be accommodated in one line control unit wiring board.

FIG. 2 uses a circuit board having the same structure as the circuit control circuit wiring board 4 shown in FIG. 1 to enable control of a plurality of circuit corresponding parts for accommodating low speed circuits by one circuit control processor, and In this example, each functional unit is housed so as not to reduce the mounting efficiency of the board. That is, in the embodiment of the present invention shown in FIG. 2, the line extension wiring board 3 shown in FIG. 3 is mounted instead of the above-mentioned second line control processor 2, whereby the first line interface unit is provided. Control signal group 1e
However, the line extension relay signal line group 3a wired on the line extension wiring board 3 is connected to the second line interface control signal group 2e.

As a result, the first line control processor 1
Is a control signal of the first line control processor 1
Of the line-corresponding-portion control signals 1e, the line-corresponding-portions 1a to 1d of the first line-corresponding-portion group and the second line-corresponding-portion group,
It is connected to 2a to 2d, and it is possible to control all of these line corresponding units.

As shown in FIG. 3, the line expansion wiring board 3 connects the first line-corresponding section control signal group 1e to a pin which is not used by the second line-control processor 2 to support the second line. The group control signal group 2e is transferred to the second line control processor 2
Of the second line-corresponding part control signal group 2e, and the pins allocated to the second line-corresponding part control signal group 2e are connected by the line expansion relay signal line group 3a on the line expansion wiring board 3. It

In the embodiment of the present invention shown in FIGS. 1 and 2, the line numbers assigned to the line corresponding units 1a to 1d and 2a to 2d are installed in the higher processor based on the configuration information. It is determined by the generation of the communication control program.

Next, details of the mounting method for accommodating the high speed line and the low speed line in the above-described embodiment of the present invention will be described.

In accommodating high-speed lines, the performance of the line control processor is generally a bottleneck, and the number of accommodated lines is limited by the performance of the line control processor, not by the area where the line interface is mounted. Therefore, it is necessary to mount a plurality of line control processors to increase the accommodation of high-speed lines.

As a mounting method for this purpose, the present invention mounts a device as shown in FIG. That is, as shown in FIG. 1, two line control processors can be mounted on the line control circuit wiring board 4, and the number of line corresponding units controlled by each line control processor can be set to a number corresponding to the performance of the line control processor. In accordance with the generation of the communication control program, the line corresponding parts 1a, 2a, ... Are assigned a younger line number and the line corresponding parts ... 1d, 2d are assigned an old line number. ..

As a result, the embodiment of the present invention shown in FIG. 1 can efficiently accommodate a high speed line.

On the other hand, accommodation of a low-speed line is contrary to accommodation of a high-speed line, and is not a performance bottleneck of the line control processor, but the number of accommodated lines is generally limited by the lack of a mounting area for the line interface. Target.

Therefore, in order to accommodate a low speed line efficiently, it is necessary to increase the number of line corresponding units controlled by one line control processor. However, if many low-speed lines are to be accommodated by the mounting method as shown in FIG. 1, in terms of the performance of the line control processor, it is necessary to mount two line control processors where only one line control processor is required, resulting in poor cost performance. Become.

According to the present invention, therefore, the cost performance can be improved by mounting as shown in FIG.

That is, as shown in FIG. 2, only one line control processor is mounted on the line control wiring board 4 and the line expansion wiring board 3 is mounted in place of the line control processor 2 so that the line expansion wiring is achieved. By increasing the number of line interface units that can be controlled by the line control processor 1 via the board 3, the line interface units 2a are numbered by 2b, 2c, 2d by generation of the communication control program.
The line numbers are assigned in the order of 1a, 1b, 1c, 1d.

As a result, the embodiment of the present invention shown in FIG. 2 is capable of accommodating a low-speed line with excellent cost performance by making full use of the performance of the line control processor.

The method of assigning the line number to each line corresponding part by the generation of the communication control program does not need to be limited to the above-mentioned method, but can be assigned by any method.

In the embodiment of the present invention shown in FIG. 2, when the line control processor has no unused pin for connecting the above-mentioned first line interface control signal group 1e,
A line expansion wiring board 3 mounted in place of the second line control processor 2 without connecting the first line corresponding unit control signal group 1e between the line corresponding unit 1a and the second line control processor 2 Can be mounted so as to straddle the mounting positions of both the line corresponding unit 1a and the line corresponding unit group 2d, thereby slightly reducing the line capacity, but with the same effect as the above case. Obtainable.

In this case, as a matter of course, the wiring of the line extension relay signal line group 3a of the line extension wiring board 3 is made up of the first line corresponding unit control signal group 1e and the second line corresponding unit control signal group 1e of the line corresponding units 1a and 2d. It is necessary to connect between the same pins as the line interface control signal group 2e.

Although the above-described embodiment of the present invention has been described as being implemented using the line control section wiring board capable of accommodating two line control processors, the present invention is not limited to the line control section wiring board. Allows more line control processors to be accommodated, divides a number of lines into groups with the same number as the number of line control processors accommodated, and controls one line control processor to control the line corresponding units of each group. It is possible to implement such an implementation. Also in this case, a part of the plurality of line control processors can be removed, and the line corresponding unit group controlled by the removed line control processors can be controlled by the remaining line control processors.

[0048]

As described above, according to the present invention,
It is possible to control multiple line interface units independently or in common according to the performance of the line control processor, so it is possible to fully utilize the performance of the line control processor, and a line with excellent cost performance. Can be accommodated.

Further, according to the present invention, it is possible to improve the mounting efficiency of the line control unit including the line control processor and the line corresponding unit group, and thereby to downsize the device.
