Abstract

PURPOSE:To easily record and maintain a system data in a memory built in a telephone set. CONSTITUTION:A write request is sent to a telephone set 1 from a data terminal 18 in the case of the write through an RS232C interface 22. A write request received by an ISDN telephone set 1 is sent to a CPU 12 from an RS232C interface control circuit 14. The CPU 12 discriminates the request as the write request according to a command analysis program and writes a system data to a memory 16 commanded by the write request. Then the CPU 12 sends the result of write of the system data to the data terminal 18 as a write result through the RS232C interface control circuit 14. Moreover, the CPU 12 notifies display information to a man machine interface control circuit 15 simultaneously to display a content or the like of a command sent/received at present.

TECHNICAL FIELD The present invention relates to telephone systems, and in particular to ISD
N (Integrated Service Digi)
tal Network) relates to a telephone system including a telephone connected to a line.

0002

[Prior Art] Conventionally, telephones (
ISDN telephones (hereinafter abbreviated as ISDN telephones) require registration of various system data such as speed dial and abbreviated dial data and own number. When registering the system data, the telephone is equipped with a numeric keypad for dialing, keys and displays for each function, and input operations are limited to using these keys and displays.

However, with the above-mentioned conventional ISDN telephone, it is necessary to register a large amount of system data such as own subscriber number and sub-address when introducing the system or changing ISDN subscriber conditions. Since the operations and displays for the related data are not originally intended for data entry, but are limited to keys and displays provided for telephone dialing, etc., it takes a lot of effort, especially when entering a large amount of data. The disadvantage was that it took a lot of time.

[0004] Furthermore, in order to record the system data once input, there is a drawback that a great deal of effort is required for recording and storage, such as manually copying and managing the data on paper. Furthermore, even if it is recorded, if the system data in the ISDN telephone is initialized due to a failure etc., it will have to be input again.
The drawback was that it required a lot of effort.

[0005]

OBJECTS OF THE INVENTION The present invention has been made to solve the above-mentioned conventional drawbacks, and its purpose is to provide a telephone system in which recording and maintenance of telephone system data is easy.

[0006]

SUMMARY OF THE INVENTION A telephone system according to the present invention is characterized by having a telephone including a memory for holding its own system data, and an external computer that accesses the system data in the memory.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a telephone, which is the main part of an embodiment of the telephone system according to the present invention. In the figure, the IS in the telephone system of this embodiment is
The DN telephone 1 includes a CPU 12, an ISDN interface control circuit 13, an RS232C interface control circuit 14, a man-machine interface control circuit 15,
It also includes a memory 16 that holds system data.

[0009] The ISDN interface control circuit 13 includes:
It controls the interface with the ISDN line 17, and also controls line synchronization and link establishment, as well as message transmission and reception.

[0010] The CPU 12 includes an ISDN interface control circuit 13 and an RS232C interface control circuit 14.
, controls the man-machine interface control circuit 15, and implements the functions of the telephone according to system data held in the memory 16. Note that 18 is a data terminal used for accessing system data.

FIG. 2 is a block diagram showing an embodiment of a telephone system using the ISDN telephone 1 of FIG.
The DN telephone 1 is connected through an RS232C interface 22 to an external personal computer (hereinafter abbreviated as PC) 23 which is a data terminal.

Next, FIG. 3 shows the system data reading and writing operations in the telephone system of this embodiment.
This will be explained with reference to the sequence chart.

First, upon reading, a read request 31 is sent to the ISDN telephone 1 from the data terminal 18 such as a PC through the RS232C interface 22. The read request 31 received by the ISDN telephone 1 is sent to the RS
The data is sent from the H.232C interface control circuit 14 to the CPU 12. The CPU 12 reads the system data specified by the read request 31 from the memory 16 according to the command analysis program, and sends it to the data terminal 1 as a read result 32 through the RS232C interface control circuit 14.
Send on 8th. At the same time, the CPU 12 notifies the man-machine interface control circuit 15 of display information, and displays the contents of the command currently being sent and received. FIG. 4 is a display example of the display information when the read result 32 is transmitted.

On the other hand, when writing, a write request 33 is sent from the data terminal 18 to the telephone 1 through the RS232C interface 22. In the ISDN telephone 1, the received write request 33 is sent from the RS232C interface control circuit 14 to the CPU 12. The CPU 12 determines the write request 33 according to the command analysis program, and writes the system data instructed by the write request 33 into the memory 16. Next, the CPU 12 sends the result of writing the system data to the data terminal 18 as a write result 34 through the RS232C interface control circuit 14 according to the command analysis program. At the same time, the CPU 12 notifies the man-machine interface control circuit 15 of display information, and displays the contents of the command currently being sent and received. Figure 5 shows the write result 3.
This is an example of the display based on the display information at the time of sending No. 4.

FIG. 6 is a flowchart showing an example of a command analysis program in the telephone system of the embodiment.

First, the system waits until one character of the command is received (step 61). If received, it is checked whether the entire command string has been received (step 62). When the reception of the command string is completed, the contents of the command are examined (step 63).

If the received command is a read request, the instructed system data read process (step 6
4) and sends out the retrieved read result (step 65). If the received command is a write request, write processing of the instructed system data (step 66)
and sends out the write result (step 67). Also, if an unrecognized command is received, it will be ignored.

The above processing is repeated.

FIG. 7 shows another example of the telephone system of the present invention. The PC 2, which is a data terminal, can collect system data received from the ISDN telephone 1 and store it in an external storage device 3 such as a hard disk or a floppy disk. Further, system data created and stored in advance on the PC 2 can also be sent to the ISDN telephone 1. Furthermore, it is easy to completely replace system data when changing system conditions.

[0020] That is, the telephone system according to the present invention
An RS232C interface control circuit is installed in the SDN telephone to interface with the data terminal, and when registering system data, an access program is installed that reads and writes system data in response to commands from the data terminal. With this program, you can easily record and maintain a large amount of system data on ISDN telephones by using a data terminal such as a PC, improving the efficiency of daily work related to ISDN telephones and saving large amounts of system data. This makes it possible to improve the efficiency of work at the time of introduction.

[0021]

[Effects of the Invention] As explained above, the present invention provides an ISDN
By connecting an external computer to the telephone, there is an effect that the system data of the telephone can be easily maintained and managed.
