Abstract

PURPOSE:To identify a limited number of callers by distinguishing the caller by informing a PB signal with plural digits corresponding to an outgoing number or an outgoing subaddress when incoming is received when the outgoing number or the outgoing subaddress of an outgoing side is compared with a number set in advance at a reception side and they coincide. CONSTITUTION:The outgoing number, the outgoing subaddress, and an incoming subaddress sent from the outgoing side are transmitted to a man-machine control part 104 on a route of a driver/receiver 101, a layer 1 and 2 control part 102, a layer 3 control part 103, the man-machine control part 104. The man-machine control part 104 compares the outgoing number or the outgoing subaddress of the outgoing side with the number set in advance at the man-machine control part 104 by a dial key and function key 114. When coincidence is obtained, the man-machine control part 104 sends the PB signal corresponding to the outgoing number or the outgoing subaddress on the route of a PB signal oscillator 106, pn analog signal processing circuit 109, a speaker 112, and performs the distinguishment of the caller. In such a way, it is possible to identify the limited number of callers.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to communication terminal equipment that performs caller identification in an 15DN network (integrated digital communication network).

(Prior Art) (1) For telephones connected to and used in the conventional analog telephone network.

Due to the nature of analog telephone networks, callers are identified before answering.

It is impossible to notify the other party, and in order to identify the other party, once a response is received, the other party is made to send out a PB double signal as a personal identification number.

+21 In the l5DN network, the dial number is displayed visually using the information of 1 the calling number or sub-address, but 2. When a call is received, 2 the calling party's calling number or sub-address and 1 the called party's calling number or sub-address are displayed in advance. There is no example of comparing set numbers and, if they match, broadcasting a PB double signal corresponding to the calling number or calling sub-address to distinguish between the two callers.

The 2nd destination subaddress is used to allow two separate terminals that can be connected to one 15DN line to receive calls, and the 1st destination subaddress is used as the password.

When receiving a call, there is no device that compares the called sub-address of the calling side with the called sub-address set in advance for the called party and, if they match, broadcasts a PB double signal corresponding to the called sub-address.

(Problem to be Solved by the Invention) In the case of a telephone connected to and used in a conventional analog telephone network, when a caller is identified and a specific ring tone is announced for each incoming call, as described above, After answering, it is necessary to receive a special signal to identify the caller, so the caller must press the pushbutton and send out a PB signal every time they make a call. There is a drawback that.

In the ISDN network, when a call arrives, the caller is identified and P
Notification using B sound is not performed.

Further, the calling subaddress of the 15DN network is not used as a password to identify the caller and notify the caller with a PB tone when a call arrives.

(Means and effects for solving the problem) In order to solve the above-mentioned problems, the present invention identifies the calling number or calling sub-address when receiving a call, broadcasts a PB double signal corresponding to the calling number or calling sub-address, and The caller is identified by distinguishing the ringtone from the ringtone.

In addition, when the first call is received, the called sub-address is identified and a PB double signal corresponding to the second called sub-address is sent out to distinguish it from other ringtones. It becomes possible to notify that the call is received from someone else.

(Example) An example of the present invention will be described in detail below with reference to the drawings.

In the 15DN network, a calling party sends a calling subaddress and a calling party subaddress from a calling party to a receiving party.

The calling number 2 subaddress and called subaddress sent by the calling side are sent to the driver/receiver 101. -Layer 1.2
Control unit 102-layer 3 control unit 103. -Man-machine control unit 104. The information is transmitted to the man-machine control unit 104 via the route . The man-machine control section 104 compares the calling number or calling sub-address of the two calling parties with the number set in advance in the man-machine control section 104 using the dial keys and function keys 114, and if they match, the man-machine control section 104 , PB signal oscillator 106-analog signal processing circuit 109
- An FB double signal corresponding to the calling number or calling sub-address is sent on the route of the speaker 112 to distinguish the calling party.

When an arbitrary number (4 digits in ISDN network) is set as the destination sub-address in the man-machine control section 104, the destination sub-address sent by the calling party is set to the machine control section 104.
If the identified number matches the preset number, the man-machine control unit 104 activates the PB signal oscillator 106-
A 4-digit PB multiplication signal corresponding to the called sub-address is sent through the route from the 7 analog signal processing circuit 109 to the speaker 112 to notify that the call is from a caller who knows the called sub-address as a password.

(Effects of the Invention) As explained above, by identifying the calling number 9 sub-address and called sub-address of the present invention, when a call arrives, the PB double signal corresponding to the calling number 2 sub-address and called sub-address is broadcast. This makes it possible to identify the caller and the limited number of callers who know the PIN number, and its practical effects are extremely large.

Note that the PB signal oscillator is used to enable access to existing analog telephone services even on digital communication terminals.
It generally has a B signal transmission function (in-channel PB signal transmission function), and the PB signal oscillator used for this function can be shared with the function of the present invention, so there is no need to increase the equipment price. realizable.
