Abstract

PURPOSE:To ensure a stable, accurate and economical indication for start of the remote maintenance by detecting a remote maintenance start indication signal of a circuit through a service processor and confirming the side where the remote maintenance indication is delivered. CONSTITUTION:A telephone call is given to an optional system which is going to start the remote maintenance from a remote maintenance center 9 via an exchange station. Thus a call signal is sent to a service processor SVP4. An SVP processing part 5 detects the call signal and connects circuits to fix a data link. The part 5 receives a password from the center 9 and compares it with the value of a password register 6. Then the part 5 executes the remote maintenance by subsequent indications given from the center 9 if coincidence is obtained from said comparison. In case no coincidence is obtained or the center 9 has no reply, the remote maintenance is not carried out. Then the circuit is immediately cut off.

Conventionally, instructions to start remote maintenance of data processing systems using public telephone lines have not generally been given. The main reason for this is that since the instruction to start remote maintenance is given from a regular telephone, it is difficult to protect confidentiality from mistakes or malicious parties.

On the other hand, it is thought that small-scale data processing systems will become widespread in offices, etc. in the future, and in response to this, new maintenance formats will be needed, such as remote maintenance from a center without staff at the site. It is desirable to adopt a remote maintenance method in accordance with the above.

The present invention provides a data processing system equipped with a central processing unit, a service processor, etc., in which the service processor has a maintenance function within the system as well as a communication function with a remote maintenance center, and the service processor performs remote maintenance of a line. The start instruction signal is detected and the remote maintenance start instruction source connected to the line is confirmed. If the remote maintenance start instruction light is confirmed, system maintenance is started and the remote maintenance start instruction source is confirmed. If this is not the case, system maintenance will not be started and the line will be disconnected.
