Abstract

PURPOSE:To automatically produce line controlling information by providing line attribute displaying registers which display attributes of lines to line adapters and reading out and storing in a memory contents of the registers by a program at the time of initializing a communication control processor. CONSTITUTION:A processor 3 produces line controlling information 21 required for controlling a line to be housed in a line interface section 41 in a memory 2 based on the content of a line attribute displaying register 51. Then the processor 3 reads out the content of the line attribute displaying register 52 corresponding to a line interface section 42 and produces the line controlling information 21 of the section 42. Thus the processor 3 produces the line controlling information 21 of all line interface sections by reading out the line attribute displaying registers of all line adapters in a communication control processor. When it becomes necessary to use the line interface section 43 of an unused line, the processor changes the value of a line attribute displaying register 53 to the attribute of a used line and produces the line controlling information 21 and, at the same time, informs the host device 7 of the communication control processor of the change.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method for setting line control information necessary for line control in a communication control processing device, and the present invention relates to a method for setting line control information necessary for line control in a communication control processing device. The present invention relates to a line control information setting method for a communication control processing device that reads changed attributes and automatically creates line control information.

(Prior Art) A communication control processing device compiles line attributes such as line speed and line interface for each accommodated line as line control information in memory, and uses this information to determine the line speed and line interface. Information such as each line Agebuta (
In addition to performing initial settings on the LA), signal line monitoring and control, data transmission and reception control, etc. are performed according to the line type set in the information. Since the types of lines and the number of lines accommodated differ depending on the device, the line control information differs depending on the device. For this reason, this information has been created in advance for each device by system generation (SG).

(Problem to be solved by the invention) Therefore, when the type of line to be accommodated or the number of lines to be accommodated changes, it is necessary to perform system generation again and recreate the line control information, and the problem is that it is not possible to deal with these changes flexibly. was there.

An object of the present invention is to eliminate the need for another system generation even if it becomes necessary to change line attributes such as line speed and line interface accommodated in a communication control processing device, and to be able to deal with these changes flexibly. It is.

(Means for Solving the Problems) A feature of the present invention for achieving the above-mentioned object is a memory that is located between a communication line and a host device and stores line control information necessary for line control, and a memory that connects the line. - A communication control processing device that has a line adapter to accommodate and a processor that controls the line attack and monitors and controls the signal line of the line and controls data transmission and reception, and controls the line based on line control information. The line adapter is equipped with a line attribute display register that stores line attributes, and based on a notification from a line attribute change recognition unit that recognizes changes in line attributes due to the line attack, the processor reads the line attributes into the memory. This is a method for setting line control information in a communication control processing device, in which line control information is set on the top of the memory, and the contents of the memory are read by a host device.

(Function) Conventionally, communication control processing devices control lines using line control information that compiles line attributes for each line.

Since line control information differs depending on the device, the device provider
Line control information was created in advance through system generation.

The present invention provides a line attribute display register for displaying line attributes in a line adapter, and when initializing a communication control processing device,
By reading the contents of the line attribute display register for line attack using a program and storing it in the memory, line control information can be automatically generated by the program.

Furthermore, when the contents of the line attribute display register are changed, the contents are stored in the memory by interrupting the processor. It also interrupts the host device to notify it that there has been a change in the content.

(Example) FIG. 1 shows an example of the present invention. In Figure 1, ■
2 is a memory that stores line control information; 21 is line control information; 3 is a processor that controls a line adapter; 41, 42, 43 .
44 is a line interface section; 5 is a line adapter that accommodates the line interface sections 41, 42, 43, and 44;
1.52.53.54 are line attribute display registers in line attack 5 that display the attributes of the line corresponding to the line interface section 41.42.43.44, and 6 indicates that the line attribute display register has been changed. A line attribute change recognition unit 7, which recognizes the information and instructs the processor 3 to create line information, is a higher-level device of 1.

An example of the operation of the line control information setting method will be explained using FIG. In FIG. 1, processor 3 reads the contents of line attribute display register 51 in line adapter 5 in accordance with instructions from line attribute change recognition unit 6. Based on the contents of the line attribute display register 51, the processor 3 starts creating line control information 21 necessary for controlling the line accommodated in the line ink face unit 41 in the memory 2. When the creation of the line control information 21 of the line interface section 41 is completed, the processor 3 similarly creates the line ink interface section 42.
The contents of the line attribute display register 52 corresponding to the line attribute display register 52 are read out, and the line control information 21 of the line interface unit 42 is created. In this way, the line attribute display registers of all line adapters in the communication control processing device are read out to create line control information 21. At this time, if the line accommodated in the line ink face section 43 is unused, the line attribute display register 53 indicates that the line is unused.
Only the area corresponding to the line interface section 43 of the line control information 21 is reserved and processing is continued with it blank.

If it becomes necessary to use an unused line interface unit 43, the value of the line attribute display register 53 is changed to the attribute of the used line. The line attribute change recognition unit 6 recognizes that the value of the line attribute display register 53 has been changed,
The processor 3 is notified that the line attributes have been changed.

The processor 3 follows the instruction from the line attribute change recognition unit 6 to create the line control information 21 of the line interface unit 43, reads the line attribute display register 53 whose value has been changed previously, and creates the line control information corresponding to the line attribute display register 53. 21 is created, and the host device 7 of the communication control processing device is notified of the fact that 21 has been changed through an interrupt.

The host device 7 changes the control information necessary for the process 7 by receiving the change content from the communication control processing device 1.

Each of the line attribute display registers (51 to 54) has, for example, a 17-bit configuration (bit 0 to bit 16), and an example of the configuration is shown in Table 1. It goes without saying that by providing the line adapter 5 with transmission control attribute information, it is possible to automatically generate the transmission control information 21.

(Effects of the Invention) According to this method, even if it becomes necessary to change the line type or line speed of the line accommodated in the communication control processing device, increase or decrease the number of lines, etc., it is possible to flexibly respond to changes in the line system configuration. It also notifies the higher-level device that the line control information has been changed.
Since the control information of the host device can be dynamically changed, the system generation work that was conventionally performed can be eliminated.
