Reference numerals 4 and 15 denote wireless telephones. In the connection device 11,
1 is an I interface for ISDN, 2 is a control unit,
Reference numeral 3 denotes an operation unit; 4a, 4b, and 4c, memory units; and 5, a wireless transmission / reception unit. Each of the wireless telephones 13, 14, and 15 has the same configuration, 7 is a wireless transmission / reception unit, 8 is a control unit, and 9 is an operation unit. Note that, in the configuration diagram of FIG. 1, a dial unit, a handset, a man-machine interface unit such as a speaker for notifying an incoming call, and the like, are omitted from the drawing.

An embodiment of the present invention will be described below with reference to FIG.

The ISDN cordless telephone according to the present embodiment includes three wireless telephones (1) connected via a wireless line 12 to a connection device 11 connected to an ISDN line 10.
3, 14, 15).

As shown in FIG. 1, the connection device 11 basically includes an I interface unit 1, a control unit 2, an operation unit 3, memory units 4a, 4b, 4c, and a radio transmission / reception unit 5. The I interface unit 1 performs an outgoing / incoming interface with an ISDN line. The control unit 2 is a control unit that performs system control of the entire cordless telephone device.

The present control unit selects whether to respond to all incoming calls or only to incoming calls from numbers registered in advance in the memory units 4a, 4b, and 4c (hereinafter referred to as "selected incoming call"). ), And in the case of a selective incoming call, detection of calling-side telephone number information (hereinafter referred to as a calling-side telephone number) transmitted from the ISDN network at the time of the incoming call;
A comparison is made between the telephone numbers registered in 4b and 4c and the calling telephone number, and if they match, the connected wireless telephone information registered in the memory unit is continuously read out, and a call is received by the wireless telephone according to the information. It has the function of not connecting incoming calls if they do not match.

The memory sections 4a, 4b and 4c are memories for registering telephone numbers. The operating section 3 is used to register predetermined telephone numbers and wireless telephone numbers for each memory in this memory section. The contents of this memory are used as abbreviated dialing memory for transmitting only the telephone number information of the memory at the time of outgoing call, and are used as a response destination telephone number for designating a response destination at the time of receiving an incoming call at the time of selective incoming call setting. Further, when the calling telephone number matches the telephone number in the memory, the wireless telephone information registered in the memory is used as the connection destination wireless telephone information.

The radio transmission / reception unit 5 is under the control of the control unit 2 and communicates with the radio telephones 13, 14, 15 via the radio line 1.
Form 2

Each of the radio telephones 13, 14, and 15 has the same configuration, and basically includes a radio transmission / reception unit 7, a control unit 8, and an operation unit 9, as shown in the figure.

The wireless transmission / reception unit 7 forms a wireless line 12 with the connection device 11 under the control of the control unit 8. The operation unit 9 has a dial button, a call button, a call end button, a hold button, and the like. In response to the operation of these buttons, the control unit 8 forms a corresponding signal and transmits it to the connection device 11 via the wireless transmission / reception unit 7 and the wireless line 12.

The operation at the time of setting the selective incoming call in such a configuration will be described below.

As an example, now, 111-1111 as a telephone number, 13 as a radio telephone number for incoming connection, and 222-2 as a telephone number in the memory unit 4b are stored in the memory unit 4a.
222, using the operation unit 3, register 14 as the incoming call wireless telephone number, register 333-3333 as the telephone number and 15 as the incoming call wireless telephone number in the memory unit 4c.

In this state, the telephone number 22 is transmitted via the ISDN network.
When there is an incoming call from the telephone having the 2-2222, the I interface unit 1 is connected to the ISDN network and transfers the incoming information to the control unit 2. The control unit 2 that has received the incoming call information determines whether the incoming call has been selected. In this case, assuming that the incoming call has been selected, the caller telephone number included in the incoming call information is read and compared with the contents of the memory unit 4a.
Since the contents of the memory unit 4a do not match the contents of the calling telephone number, the control unit 2 compares the contents of the memory unit 4b with the calling telephone number. Since the contents match, the wireless telephone information 14 for incoming connection is read out continuously, and incoming connection is made to the wireless telephone 14 via the wireless transmitting / receiving unit 7. The following connection procedure is based on the connection procedure of a normal cordless telephone. With such control, it is possible to connect to an arbitrary wireless telephone according to the telephone number of the caller.

FIG. 2 is a generalization of the operation flow described above.
Is shown in the flowchart of FIG.

[0021]

As described above, the ISDN of the present invention is
According to the corresponding cordless telephone device, an incoming call from a registered telephone number is connected only to a specific wireless telephone,
This has the advantage of omitting the transfer operation to the caller, saving labor and providing an excellent ISDN-compatible cordless telephone device that can be used.
