DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a subscriber information control method in a telephone terminal, and in particular to a control method for registering or changing subscriber data in a telephone terminal such as a stored program-controlled button telephone device or a high-performance telephone. It is related to.

When the number of extension telephones in a private branch exchange is small, a simple exchange device mainly configured to select a central office line, that is, a key telephone device (also referred to as a key telephone) is provided as a telephone terminal.

A system in which a microcomputer controls this key telephone device using a stored program is called an electronic key telephone system (hereinafter referred to as EKTS), and it allows you to call from the telephone to another line while keeping the line in use on hold. A function to make calls or calls between key telephones, a function to send music indicating that the line is on hold to the other party when the line is on hold, a confidential function to prevent the voice of other key telephones from being heard during a call, a button A function that uses voice as a calling method between telephones or a function that calls two or more telephones at the same time is executed by pressing a button on the telephone.

FIG. 1 is a block diagram of a conventional electronic key telephone system.

As shown in FIG. 1, the EKTS is composed of a main device 1, key telephones 2-1, 2-2 to 2-n, and a keyboard 14, and the main device 1 further includes central office line trunks 4-1 to 4-m, Switch matrix 12, button telephone trunk 9-1
~9-n, switch drive circuit 11, input/output interface 5, memory 7, OPUS, switch, pin board 13
, and an operation panel 15.

First, when a call is received from the office line 3 to the EKTSI, the office line trunk from which the call was received among the office line trunks 4-1 to 4-m detects the incoming signal from the office, and the 1/0 interface 5
forward this information to.

This information is given from the 1/0 interface 5 via the data address bus 6 to the memory 7 and CPU 8, where it is stored and processed in accordance with the stored program. The 0PU 8 captures the corresponding trunk 9 of the key telephone trunks 9-1 to 9-n via the 1/O interface 5, and sends an activation signal from the trunk 9 to the key telephone 2 via the extension 10. do.

This activation signal activates the bell in the button telephone 2 and calls the called party. Upon the called party's response, the key telephone trunk 9 detects the answer status and notifies the CPU 8 of this status via the 1/0 interface 5.

The 0PU8 activates the switch drive circuit 11 via the 1/0 interface 5 according to the program.

This switch driving circuit 11 drives a switch matrix 12 to connect the terminating office line trunk 4 and the key telephone trunk 9, thereby forming a link between the office line 3 and the key telephone 2 and allowing a call to be made.

In such EKTSl, (1) linker ringing conditions to notify incoming calls on the central office line (i.e., determining whether or not to ring the linker for each key telephone), (2) specifying the central office line that can be called, (3) ) Specifying an extension number for group calling to call specific key telephones all at once, (4)
If a central office line call is left on hold for a certain period of time, it will return to the central office line incoming state and the lamp and linker will operate. (5) Various service functions (e.g. ringtone stop function) It is necessary to set various data regarding the subscriber, such as designation of the function of the function key to execute (6) (6) designation of the call forwarding destination, etc., as memory information or input conditions of the storage program control method.

Conventionally, in order to write such various data to the memory 7, subscriber data is set using a pinboard or dip switch 13, etc., and then written to the memory 7 via the 1/0 interface 5. There is.

Further, the subscriber data in the memory 7 is rewritten using an input device such as the keyboard 14 or the operation panel 15 that can rewrite the memory 7. However, such a subscriber information control method has the following drawbacks.

That is, in the dip switch, pin board 13, etc., the status of subscriber data set by the switch lever and pin can be visually read immediately, but when such a device is installed in the main device 1, The space required to set ~100 bits of subscriber data occupies a very large portion, and mounting these switches, pin boards 13, etc. in a way that is easy for operators to operate requires a large amount of mounting capacity, switches, pins, etc. This is extremely disadvantageous in terms of the cost of the board, etc. Furthermore, when subscriber data inside the memory 7 is rewritten using the keyboard 14 or the operation panel 15, the operation is complicated and additional hardware is required.

That is, the subscriber data registration rewriting procedure requires two steps: first specifying the address of the memory 7 to be rewritten using the keyboard, then inputting the data, and the pin board, dip switch 13, etc. In contrast, using the keyboard 14 or the operation panel 15 requires a much more complicated operation.

Moreover, it is necessary to use an operation manual to instruct input data procedures and data formats.
Furthermore, in addition to the keyboard 14 and operation panel 15, it is necessary to provide hardware such as an indicator lamp for visually confirming the input data, so it is less economical and easier to implement than a pin board or dip switch 13. There is no advantage. In addition, in order to confirm the subscriber data on the keyboard 14, etc., the address of the memory 7 is specified each time using a key, etc., as in the case of writing.
Since confirmation is performed using an indicator lamp, etc., operation is complicated, an operation manual, etc. is required, and subscriber data cannot be viewed at once. The purpose of the present invention is to
In order to largely eliminate these drawbacks of the conventional method, it is possible to visually view subscriber data, and the operation is much simpler.Moreover, the installation space is reduced, which is economically advantageous. The purpose of this invention is to provide a subscriber information control system for telephone terminals.

The subscriber information control method for a telephone terminal according to the present invention records subscriber information for operating the telephone terminal in a telephone terminal equipped with an electrically rewritable memory, and records the subscriber information for operating the telephone terminal. A portable writing device is provided externally, and includes a visible recording medium, a means for reading information written on the recording medium, and a means for transmitting the information read by the reading means to the memory, and the writing device is connected to the memory, subscriber information is written on the recording medium and inputted to the reading means, the subscriber information is temporarily stored in a temporary storage means built in the writing device, and written into the memory. It is characterized by converting it into the format required for writing.
