Abstract

PURPOSE: To set a time of a system clock of a private branch exchange automatically. CONSTITUTION: A system restart message signal is generated at the end of system restart by a private branch exchange 2 and sent to a maintenance terminal equipment 1. The maintenance terminal equipment 1 reads a current time from a master clock and generates a system time setting signal and sends it to the private branch exchange 2. Upon the receipt of the signal, the private branch exchange 2 sets the time to the system clock based on the time information in the system time setting signal to set the clock of the private branch exchange 2 automatically.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time setting system, and more particularly to a time setting system for setting the current time of a master clock to a system clock when a private branch exchange is started up.

[0002]

2. Description of the Related Art Conventionally, the time setting of a system clock at the time of startup of a private branch exchange is performed by a maintenance person from a maintenance terminal or a control panel of the private branch exchange, or by accessing the public network from the private branch exchange. An access system from the exchange to the public network is disclosed in, for example, Japanese Patent Laid-Open No. 4-246998.
There is a time adjustment method of JP-A No. 62-266953, an automatic time information setting method of JP-A No. 62-266953, or a time correction method of an internal clock of a switch of JP-A No. 63-15191.

In the time adjustment method of Japanese Patent Laid-Open No. 4-246998, the date and time information contained in the call setting message received from the ISDN network is identified on the exchange side, and the hard clock of the exchange is set to the standard clock on the ISDN network side. The time correction method for the internal clock of the exchange disclosed in Japanese Patent Laid-Open No. 63-15191 is automatically transmitted to the time signal service network periodically, receives time information from the time service network, and compares it with the internal clock of the exchange. The internal clock is time-corrected based on the comparison result, and the automatic time information setting method disclosed in Japanese Patent Laid-Open No. 63-266953 calls a time information service by an automatic call transmitting / receiving device having a voice recognition function in the exchange. However, the exchange clock device is automatically set based on the received time information.

[0004]

This conventional clock setting by the maintenance person is accompanied by the time setting operation by the maintenance person, and not only the time and effort of the maintenance person but also the risk of erroneous operation. Further, there is a drawback that an automatic call-in / out device and a voice recognition device for the public network are specially required to obtain the clock information from the public network.

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a private branch exchange and a maintenance terminal showing an embodiment of the present invention.

Referring to FIG. 1, the private branch exchange 2 of the present embodiment activates a communication control unit 21 that controls an interface during communication with the maintenance terminal 1 and a restart processing program at initial startup or restart. A system restart control unit 23 that executes a system restart process, and a system operation management unit 22 that receives a restart process completion notification from the system restart control unit, generates a restart process completion message, gives a message type number, and notifies the maintenance terminal. And a system clock 25 for controlling the setting of the current time based on the master clock information from the maintenance terminal 1.

Further, the maintenance terminal 1 analyzes the maintenance signal received from the private branch exchange 2 and the communication control section 11 which controls the interface at the time of communication with the private branch exchange 2 and analyzes the maintenance signal received from the private branch exchange 2 to perform message signal processing means. And a restart signal completion message is received from the private branch exchange, and a maintenance signal processing unit 12 that receives a request to send the current time from the system clock processing unit to the private branch exchange and executes a process of transmitting this current time information. The message processing unit 13 that identifies that the received message is the restart processing completion message from the message type number given to the restart processing completion message, and instructs the sending of the current time of the master clock, the master clock 15, and the master The current time of the clock is read out and the system clock 25 of the private branch exchange 2 is read.
And a system clock setting unit 14 that generates a clock setting signal for setting the current time.

Next, the operation of the present invention will be described. The private branch exchange 2 restarts the system (starts up) under the control of the system restart control unit 23 by a command input by the maintenance person from the maintenance terminal 1 or by turning on a predetermined power switch of the private branch exchange, and the system restarts. Upon completion, the system restart control unit 23 sends a system restart completion notification on the exchange side to the system operation management unit 22. Upon receiving the system restart completion notification, the system operation management unit 22 generates a system restart message signal indicating that the startup of the private branch exchange has been completed, and transmits it to the maintenance terminal 1 via the communication control unit 21.

On the other hand, in the maintenance terminal 1, the maintenance signal processing unit 12 receives the system restart message signal via the communication control unit 11 and activates the message signal processing unit 13. The message signal processing unit 13 identifies that it is a system restart message from the message type number added to the received system restart message signal, and activates the system clock setting unit 14. The system clock setting unit 14 reads the current time information from the master clock 15, generates a system clock setting signal, and makes a transmission request to the maintenance signal processing unit 12.

Upon receiving the transmission request, the maintenance signal processing unit 12
The received system clock setting signal is transmitted to the private branch exchange 2 via the communication control unit 11. The system operation management unit 22 of the private branch exchange 2 receives the system clock setting signal via the communication control unit 21, activates the system clock control unit 24, and sets the system clock 25 based on the time information of the signal. To do.

[0013]

As described above, according to the present invention, when the private branch exchange sends the system restart completion message to the maintenance terminal, the maintenance terminal which has received this transmits a system clock setting signal to the private branch exchange and receives it. Since the private branch exchange sets the time of the system clock, there is an effect that the clock of the private branch exchange can be automatically set without the operation of a maintenance person or the need for a special device.
