The data setting control unit 1 controls data setting. The line connection control memory 2 is connected to the data setting control unit 1 and stores set data, that is, connection information for performing line connection, and controls line connection. The line connection unit 3 is connected to the line connection control memory 2 and connects the line based on the set data. According to this data setting method, the data setting from the data setting control unit 1 is performed directly with respect to the line connection control memory 2 after arbitration with the line connection unit 3.

[0003]

In the conventional data setting method, it is necessary to perform data setting from data setting control in a gap between access from the line connection unit to the line connection control memory. The time required for the data setting depends on the operation state of the line connection unit, which has been a factor of reducing the performance of the data setting control unit.

Further, since the line connection control memory is directly operated, it is impossible to initialize the entire area in the operating state when copying the data from the backed up memory. There is a problem in that it is necessary to individually set each item, and the processing takes time.

[0005] Therefore, an object of the present invention is to provide a data setting which can process data at high speed even when the setting area is large and the area actually used is small like the VP connection setting in the ATM transmission system. System and an ATM transmission system using the same.

It is for doing.

In this data setting method, data setting from the data setting control unit 1 is performed on the buffer memory 4. Furthermore, under the control of the data setting control unit 1,
The data transfer control unit 6 sets the data set in the buffer memory 4 in the line connection control memory 2. The line connection unit 3 controls the line connection according to the data set in the line connection control memory 2.

Note that data is set in the buffer memory 4 while data transfer from the buffer memory 4 to the line connection control memory 2 is stopped, and then data transfer from the buffer memory 4 to the line connection control memory 2 is performed. It is preferable to control the data transfer so as to perform

When copying data from a backed-up memory, it is preferable to control so that the buffer memory 4 is initialized once and then reset.

As described above, according to the present invention, the buffer memory is arranged between the data setting control section and the line connection control memory, and the data setting control section makes settings in the buffer memory. As the setting from the data setting control unit, processing can be performed without being affected by the operation of the line connection unit, and the processing time of the data setting control unit can be shortened.

In addition, in a state where data transfer from the buffer memory to the line connection control memory is stopped, data is set in the buffer memory and then controlled so that data transfer is performed. There is an effect that the change setting can be performed without affecting.

Further, the provision of the memory clear control unit enables the initialization of the buffer memory, and the buffer memory is initialized once when data from the backed-up memory is copied. By performing control so that the settings are reset later, it is possible to control only the parts that need to be set, so that when the setting data is small in the setting area, the processing time can be reduced. It has the effect of becoming.
