Abstract

PURPOSE:To attain simple abbreviation dial registration by devising the terminal equipment so that the telephone number of an opposite party communicated finally can be registered as it is in addition to the registration of the abbreviation dial due to the combination of special keys. CONSTITUTION:There are methods in the registeration of an abbreviation dial; a 1st method is the entry from an abbreviation dial registeration key 9 and a dial key 3 and a 2nd method is the entry of special combination of dial keys 3 to the transition to the registration mode for sequential registeration. In the case of line wire origination using a registered abbreviation dial, it is implemented by using the abbreviation dial key 8 and the dial key 3 and an originated opposite number is displayed on a display device 6 in both cases. Moreover, an opposite party coming during communication is displayed at the reception. In any of the cases of line wire outgoing and incoming calls, the mode transits to a mode registering the opposite party number communicated so far after the end of the communication. Thus, the outgoing or incoming opposite number is registered simply as abbreviation dial after the end of communication.

Next, an explanation will be given of an operation for making an outside call using a so-called speed dial. First, in order to make an outside call using a speed dial, it is necessary to register the speed dial. To register a speed dial, by inputting the speed dial registration key 9 shown in FIG. 3 or a special combination of dial keys 3, the system enters a registration mode and performs the registration operation in sequence.

To make an outside call using the registered speed dial, the speed dial key 8 and dial key 3 are used to make the call. In either case, the number of the caller is displayed on the display device 6.

When a call is received, the telephone number of the other party receiving the call during communication is displayed, but when the call ends, the telephone number of the other party is not stored.

[Problem to be solved by the invention] However, the conventional ISDN digital telephone terminal has the following problems:
Since the system is configured as described above, if you want to make an outside call using speed dial, you need to perform a registration operation for speed dial. Furthermore, even though the caller number is sent as a service of the ISDN network when a call is received, it is only used during communication. Therefore, there is a drawback that speed dial registration is troublesome.

[Object of the invention] The present invention was made to solve the above-mentioned difficulties.
To provide an ISDN digital telephone terminal capable of easily registering a calling party's number as a speed dial after the end of communication.

[Means for Solving the Problems] In order to achieve the above object, the ISDN digital telephone terminal according to the present invention stores the telephone number of the other party at the time of outgoing or incoming call in the ISDN digital telephone terminal connected to the ISDN network. The telephone number storage means is provided with a telephone number storage means, and a speed dial registration means connected to the telephone number storage means for registering the telephone number of the other party in the speed dial.

[Embodiments of the Invention] Hereinafter, an embodiment of the ISDN digital telephone terminal of the present invention will be described in detail with reference to the drawings. As shown in FIG. 2, the ISDN digital telephone terminal 1 of the present invention has a memory 10 as a telephone number storage means. It is equipped with a speed dial registration means 11, and, like a conventional ISDN digital telephone terminal, has a handset 2, a dial key 3, an ISDN interface 4, a communication device 5, a display device 6, a redial key 7, a speed dial key 8, and a speed dial registration key. It has 9.

The handset 2 is connected to an ISDN interface 4 via a communication device 5, and is connected to an ISDN network. The communication device 5 and the ISDN interface 4 are connected to the control device 12 . The control device 12 is connected to a dial key 3, a redial key 7, a speed dial key 8, a speed dial registration key 9, a memory 10, and a display device 6. The control device 12 includes speed dial registration means 11.

FIG. 1 is a plan view showing the appearance of an ISDN digital telephone terminal according to the present invention. The same symbols as in Fig. 2 are used.

[Operation of the Invention] The operation of the ISDN digitizer and Lumi talk terminal 1 having such a circuit configuration will be explained with reference to FIG.

Similar to the SDN digital telephone terminal 1', a call is made by inputting from the dial keys 3. Next, if you want to re-call the number that made the last external call, use the conventional ISDN
Similar to digital telephone terminal 1', redial key 7
By pressing , the control device 12 sends a signal to the memory 10, and the last used telephone number is sent again to the ISDN interface 4, thereby realizing a so-called one-touch call.

Next, the operation for making an outside call using speed dialing will be explained. First, in order to make a call using speed dial, a speed dial registration operation is performed. The first method for speed dial registration is to use the conventional SDN digital telephone terminal 1.
Similarly to ``,'' there is an input from the speed dial registration key 9. Press the speed dial registration key 9, then enter the two-digit number that will become the speed dial number using the dial key 3, then enter the phone number you wish to register, and then press the speed dial registration key 9 again. push. Also, as a second method, by inputting a special combination of dial keys 3,
Some devices shift to registration mode and perform sequential registration. For example, if you enter "*#" from the dial key 3, the message "Enter speed dial mode" will be displayed on the display device 6.
