Abstract

PURPOSE:To shorten the rise time of communication control processing equipment by independently providing a processing part program storing medium and a line control program medium each other and independently performing the loading of the program. CONSTITUTION:When the instruction of a power input and device initialization is set, the loading of the control program is started from a control program storing medium 2 to an initial program storing area in a processor in the processing part. A circuit control common part 3 detects the attribute of a line adapter group 5, and loads the line control program conforming to the attribute from a line control program storing medium 4 to the storing area. At the time of the completion of loading, a processing part 1 is notified of the completion of the loading from the common part 3, and by the interlock between the processing part 1 and the common part 3, an adapter group 5 is controlled. Then, the adapter group 5 transfers control information and data through signal line groups 11 and 12, and the control function is started. As this result, the loading to the common part 3 is performed independently of the processing of the processing part 1 at the time of the change of the adapter group 5, and the rise time of the device can be shortened.

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the communication control processing device of the present invention. A processing unit 1 including a processing processor having a function of loading a program, a storage area for storing processing programs and data, a control program storage medium 2 for storing a control program, and a line adapter group 5 to be connected. A line control common unit 3 having a line control program storage area in which a line control program is written and a control processor, a line control program storage medium 4 storing the line control program, and a line control common unit 3 based on the line control program. (The processing unit 1 and the line control common unit 3 are connected by a signal line group 11 and a signal line 13, The control common unit 3 and the line adapter group 5 are connected by a signal line group 12 and a signal line 14).

Note that the control program storage medium 2 and the line control program storage medium 4 can be realized by an auxiliary storage medium such as a floppy disk.

Next, the operation of the communication control processing device of this embodiment configured as described above will be explained.

When the communication control processing device is powered on and device initialization instructions are set, loading of the control program from the control program storage medium 2 to the control program storage area in the processor in the processing unit 1 is started.

At the same time, in parallel with the loading of the control program to the processing unit l, the attributes of the line adapter group 5 connected via the signal line 14 are detected by the line control common unit 3, and lines matching the attributes are detected. The control program is loaded from the line control program storage medium 4 to the line control program storage area in the tIIA control common section 3, and when this loading is completed, the processing section 1 is notified of the completion of the loading via the signal line 13. .

When the loading of the line control program is completed, the processing unit 1 and the line control common unit 3 are linked (mainly the line control common unit 3
The line adapter group 5 is controlled by the operation of the control processor in the line control common unit 3 based on the line control program loaded into the line control program storage area in the line control program storage area, and control information, data, etc. The data is then transferred from the line adapter group 5 to the line, and the communication control processing device of this embodiment starts functioning.

FIG. 2 is a block diagram showing the configuration of another embodiment of the communication control processing device of the present invention, which includes two communication control processing devices, their spare processing section, and line control common section (control program storage). 23 (hereinafter the same) including a medium and a line control program storage medium.

In this embodiment, one communication control processing device is constituted by the processing section, line control common section 21, and line adapter group 31, and one communication control processing device is constituted by the processing section, line control common section 22, and line adapter group 32. A control processing device is configured, and the processing section and line control common section 23 correspond to a spare processing section and line control common section of these communication control processing devices.

The processing unit and line control common unit 21 to 23 include the processing unit 1 and the line control common unit 3 in the embodiment shown in FIG. (also includes medium 4).

The line adapter groups 31 and 32 are the same as the line adapter group 5 in the embodiment shown in FIG. 23 has two sets of connection ports with connection boat B (operates by being connected to either connection boat).

Next, the operation of the communication control processing device of this embodiment configured as described above will be explained.

Processing unit and line control common unit 21 and line adapter group 31

If a failure occurs in either of the processing unit and line control common unit 21 or 22 in which the failure has occurred,
The line adapter group 31 or 32, which was connected to (switching takes place)
.

In this case, the processing unit and line control common unit 23 (startup has been performed in advance, and a line control program suitable for either of the line adapter groups 31 and 32 is loaded in the line control common unit) Then, the attributes of the line adapter group 31 or 32 to be connected are detected, and if the already loaded line control program does not match the attributes of the detected line adapter group 31 or 32, a new line control program is started. A load is made to the line control common part for modification (there may be times when the loaded line control program matches the detected attributes, in which case the line adapter based on the already loaded line control program control of group 31 or 32).

Since this line control program is loaded independently of the processing by the processing unit and the processing unit in the line control common unit 23, a situation in which the terminal recognizes that the center is down does not occur.

When the line adapter group to be controlled by the line control common unit is changed to one with different attributes other than during preliminary switching as in this embodiment, the changed line adapter group is changed independently of the processing of the processing unit. A line control program conforming to the above is loaded from the line control program storage medium into the line control common section.
