Abstract

PURPOSE:To contrive to reduce the cost and to simplify the constitution by using a dial IC with an abbreviation dial memory without having any data bus so as to input a control code and to transfer it to a control section. CONSTITUTION:A dial key 11 is used to register an ID code to a specific area (a) of an abbreviation dial memory 13 of a dialer 12 as a control code. A CPU 17 turns on a switch 15 for DTMF device by the output OUT 1 to inactivate a dial control circuit 14 and an output OUT 2 switches the dial of the dialer 12 from the DP mode to the DTMF mode at the time of writing the data. Then an output OUT 3 turns on a switch circuit 19 to send a dial key signal DK commanding abbreviation dialing of the specific area (a) of the abbreviation memory 13 to the dialer 12. Thus, the DTMF signal is fetched in the CPU 17 via the switch 15 and the DTMF receiver 16 and stored in a memory 18 as the ID code.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a functional telephone in which a control code is set and stored in advance in the telephone and functional operations are controlled based on the stored control code.

[Conventional technology]

Generally, in a telephone that uses a control code such as a personal identification code as a password, input methods include mechanical setting using a code switch and registration in a memory IC using a dial key.

[Problem that the invention seeks to solve]

However, the former method requires a multi-digit switch, which increases costs due to an increase in the number of parts, and the latter method results in the control code being cleared in the event of a power outage, so it cannot be used until one day after the power outage. In addition, it requires a configuration in which the output of the dial key is once input to the control unit, which imposes restrictions on the connection and also involves the control unit in controlling dialing, making the control complex.

On the other hand, as a solution to this problem, there is a method of directly registering the control code from the dial key in the speed dial memory of the dial IC, but the dial IC has a data bus for transferring the registered control code to the control unit. It was not commercially available and could not be realized.

In view of the above points, the present invention has been made to solve such problems.The purpose of the present invention is to use a dial IC with a speed dial key and no data bus to control code with a simple configuration. The object of the present invention is to provide a functional telephone that allows input and transfer to a control unit.

[Means for solving problems]

In order to achieve the above object, the present invention provides a function telephone in which a control code is set and stored in advance in the telephone and function operations are controlled based on the stored control code. a dialing signal generating circuit for performing speed dial registration and speed dialing; a dialing signal receiving circuit receiving the dialing signal output of the dialing signal generating circuit; a memory for storing control codes; and the dialing signal generating circuit. control means for transmitting a key output indicating a speed dial origination (f) in a specific area of the speed dial memory, and for storing in the memory an output of the dial signal receiving circuit in response to the speed dial transmission; This system is characterized by using dial data stored in memory as a control code.

[Effect]

Therefore, in the present invention, a control code is stored in a part of the abbreviated dial memory of a dial signal generation circuit as a dial IC using a dial key, and the dial signal output of the dial signal generation circuit is received as a dial signal. By directly importing the control code into the memory of the control unit via the circuit, the control code can be input and transferred to the control unit with a simple configuration.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 81 is a block diagram showing an embodiment of a functional telephone according to the present invention. In the figure, reference numeral 11 is a dial key consisting of various keys, and reference numeral 12 is a dial key 12 that performs dialing based on the key input of the dial key 11, as well as registering short 11/dial in the short dial memory 13, making speed dial calls, etc. This dialer 12 serves as a normal dial IC with functions, and has a dial mode, a DP mode, and a DTMF (dial tone multi-frequency) mode, and constitutes a dial signal generation circuit. Then, the mailer 12 has its power terminal Ve.
When off-hook due to the operation of the hook switch Is, power is supplied to C via the maiode DI by a loop current passing through the dial control circuit 14, and when on-hook, power is supplied from the battery 22 through the pmeiode D. It has become. The dial control circuit 14 is
Hook switch H8 dial signal from Mayara 12
It sends out to the line side via the line, and also receives various signals passing through the line and sends them to the call and bell playback circuit section 21, which consists of a DTMF receiver 16 and a call circuit, voice amplification, recording/playback circuit, etc., which will be described later. It becomes.

Further, 15 is a switch for DTMF bypass, 16 is a signal input from the dial control circuit 14, and
A DTMF receiver is used as a dial signal receiving circuit which inputs the dial signal generated from the mailer 12, and 1T is an in-CPTY (processor) as a control means. The way the key appears to instruct dialing, that is, the dial key signal is OK'! j-switch circuit 19, and also has a function of storing the output of the 90 TMF receiver 16 in the dial 1B in response to the short 4-dial utterance, and transmits the output from the I earer 12 and the switch 15. It controls the switch circuit 19 and the like.

Note that the reference numeral 23 is a line connection terminal connected to the line.

Next, the operation of the configuration of the above embodiment will be explained. First, using the dial key 11, for example, an ID (password) code is registered as a control code in the same manner as a dial number is registered in a specific area a of the speed dial memory 13 of the dialer 12. Then, during initialization or data writing, the CPU 17 uses its output 0UT1 to turn on the DTMF bypass switch 15, disables the dial control circuit 14, and changes the dial mode of the dialer 12 to DP mode using its output 0UT2. From DTM
Switch to I' mode. Next, after turning on the switch circuit 19 through the output 0UT3, a dial key signal DK is sent to the dialer 12 to instruct the dialer 12 to make a speed dial call to a specific area a of the short dial memory 13. This allows the dialer 12 to make a speed dialed DT.
The MF signal is transmitted through the switch 15 and the DTMF receiver 16.
is taken into the CPU 17 via the
Stored as a D code. Therefore, the CPU 17 uses the ID code stored in the memory 18 by comparing it with an ID code that arrives via a line when, for example, remotely controlling an answering machine.

Note that the dialer 12 is powered by the loop current passing through the dial control circuit 14 when off-hook, and is powered by the battery 22 when on-hook, so the ID code registered in the speed dial memory 13 is always retained. With this, it is possible to retransmit at any timing.

In the above embodiment, an example has been described in which abbreviated dial registration is performed using only the dial key 11, but the same applies to the case where a "registration key" of a function key is used. Also, dialer 1
When changing the ID code registered in the speed dial memory 13 of No. 2, the Ft and cPU 17 can access the mailer 12 by notifying the change using a specific key of the function keys.

Furthermore, the switch 15 for DTMF reception is connected to the CPU 1T.
If the output of the DTMF receiver 16 is taken in only when necessary, it may be omitted.

〔Effect of the invention〕

As explained above, according to the present invention, a dial IC with a speed dial memory that does not have a data node is used to
Since the control code is input and transferred to the control unit, no special external memory or transmission path line is required, simplifying the configuration and reducing costs. When applied to telephones, etc., the practical effects are extremely large.
