It is the procedure specified in.

As described above, even the above-mentioned conventional terminal adapter can be controlled by the control terminal directly connected to the terminal adapter and the control terminal provided at a remote place via the ISDN network.

[0008]

However, in the above-mentioned conventional terminal adapter, in addition to the communication means with the control terminal directly connected thereto, it is necessary to provide the communication means with the control terminal provided in a remote place, Moreover, since the communication procedure of the control terminal directly connected is different from that of the control terminal provided at a remote place, the controllable range is limited, or the respective procedures are different.

The present invention solves such a conventional problem, and the operation of the control terminal directly connected and the control terminal provided at a remote place can be performed in the same procedure, and the direct control and the remote control can be performed. It is an object to provide a terminal adapter with the same control.

[0010]

In order to achieve the above object, the present invention has a means for analyzing data received from a control terminal provided at a remote place via an integrated digital communication network and a means for directly receiving data from the control terminal. The means for analyzing data is common, and the communication procedure of both control terminals is the same.

[0011]

According to the present invention having the above-mentioned structure, the control terminal and the control means for receiving data from the direct control terminal are made common through the integrated digital communication network so that the control terminal directly connected to the control terminal is provided at a remote place. The control terminal can control the terminal adapter by the same procedure.
