PURPOSE:To display a caller number, a caller name and degree of emergency to a incoming telephone set, by providing a signal other than a selection signal to a signal transmitted and received between the telephone set and an exchange at calling. CONSTITUTION:A control signal representing the name of caller and degree of emergency, and a selecting signal are transmitted to an incoming side exchange 4 via a calling side exchange 3 with the dial operation of a digital telphone set 1. The exchange 4 interpretes a received dialed signal, selects the line of an incoming side telephone set 1' and transmits the control signal including a call signal to the telephone set 1' to a signal control circuit 6' via a multiplex and separation circuit 2'. Thus, the control signal is given to the telephone set 1' in the prescribed order and number of digits, and a call tone of the incoming telephone set 1 rings, and the call number, the name of caller and the degree of emergency are displayed on a display.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a signal system for a digital telephone that uses digital signals as signals exchanged between the telephone and an exchange.

In the conventional signaling system of digital telephones,
When making a call, the telephone only sends a selection signal, which is the subscriber number of the called party, as a control signal for sending and receiving calls to the exchange. Even if a control signal other than the selection signal is sent, the exchange will not receive it. Because it is configured not to attach
Even if a transparent signal path is configured from the originating exchange to the terminating exchange and the terminating telephone, the number of the originating subscriber (caller code) and terminal type registered in the originating exchange in advance It was only possible to transmit subscriber data to the called party's telephone, and it was not possible to transmit signals that varied variously each time a call was made, such as the name of the calling party, the name of the called party, and the level of urgency. .

Therefore, when a subscriber receives a call, (11) Even if the calling party number is sent, if the caller is calling from a public telephone or other line, the subscriber will go off-hook to contact the other party. The caller cannot be known in the trench.

(2) When the same telephone is used by multiple operators, the called party cannot know the called party desired by the caller until after the call has started off-hook.

(3) Even if an incoming call from a called party is highly urgent, it cannot be distinguished from a normal incoming call.

The called party may not be able to decide whether to answer or not if necessary, or if the call is received by someone other than the person who answered the call, the called party must pick up the phone and take the next steps. There are some drawbacks.

The purpose of the present invention is to fundamentally eliminate these eight drawbacks of the conventional technology, and adds signals other than the selection signal to the signals sent and received between telephones and exchanges and between exchanges when making and receiving calls. The present invention provides an extremely effective signal system for digital telephones that allows the added signal to be transparently transmitted from the called side to the packing machine.

Hereinafter, the present invention will be explained in detail with reference to figures showing examples.

Note that FIG. 3 is a flowchart showing an example of the operating procedure when the digital telephone makes a call.

Next, the control signal transfer operation at the time of originating and receiving calls will be explained.

In FIG. 1, operations of dial 19 of digital telephone 1 and predetermined order.

A selection signal and one caller name generated and assembled in response to keyboard 18 operations based on the number of digits.

Since the control signal h1 indicating the name of the called party and the degree of urgency is sent to the multiplex separation circuit 2, the control signal is separated in the same circuit 2 and sent to the signal control circuit 6.

In addition, the signal control circuit 6 transmits the selection signal to the switch 3.
At the same time, the storage device T is accessed to read out the subscriber number (caller number) of the originating subscriber, and the read subscriber number is first sent to the control circuit 5 to receive the selection signal. After insertion, the selection signal and the control signal indicating the calling party number 1, calling party name, called party name, and degree of urgency are transferred to the signal control circuit 6' of the receiving side exchange 4 in accordance with instructions from the control circuit 5. do.

At this time, the control circuit 5Fi decodes the selection signal sent from the signal control circuit 6, and outputs the audio signal and control 1.
It selects a signal communication path and issues control signal transfer instructions.

Next, the control signal transferred from the signal control unit 6 of the originating side exchange 3 is received and the signal control circuit of the 9th destination Oi side exchange 4 is transmitted.
Then, the received selection signal is sent to the control circuit 5' of the exchange a4, and the calling signal generation circuit 8 is accessed to insert the calling signal in place of the selection signal.

On the other hand, the control circuit 5' decodes the received 9-dial signal, selects the line for the called telephone 1', and also instructs the signal control circuit 6' to remove the selection signal, insert the ringing signal, and select the 9-dial signal. The control signal is controlled to be sent to the receiving telephone 1' via the multiplexing/demultiplexing circuit 2'.

Therefore, the control number 81 is sent from the calling side telephone 1 to the called side telephone 1' in a predetermined order of one digit number, and the called side telephone 1' rings and rings.
Caller number 2 Caller name, called party name.

Receive urgency.

Next, regarding the operation of digital telephones 1 and 1', i!
2BA.

In FIG. 2, when the hook switch 10 is turned on at the time of transmission, the transmission termination unit 11 extracts the power necessary for the operation of the stain filler using the line current from the subscriber line 9, and
It is a circuit that automatically equalizes the characteristics of the subscriber line 9 and establishes a delicate synchronization between the exchanges 3, 4 and the telephones 1, 1'. This is a circuit that performs speed conversion between the code transmission speed on the subscriber line 9 and the effective speed of voice signals and control signals. As shown in the example procedure, the subscriber number of the other party is entered on the pushbutton dial 22, and then the delimiter signal 2 is entered using the keyboard 18.

When you input the called party's name and the degree of urgency by a predetermined number of digits and then operate the call button 19, the signal corresponding to the calling party's name, the called party, and the degree of urgency is displayed. is generated in the signal generation circuit 13, sent to the display circuit 15 and displayed on the display 1T, and sent to the line termination section 12 and sent to the exchange @S via the transmission termination section 11.

On the other hand, when a call is received, the control signal sent from the exchange 4 is sent to the line termination section 12 via the transmission termination section 11, and the control signal is separated and sent to the nine-way signal receiving circuit 14.

Since the signal receiving circuit 14 sends control signals other than the calling signal to the display circuit 15, the display 17 displays the calling party number 2, the calling party's name, the called party's name, and the degree of urgency, which are predetermined. will be displayed according to the specified display position.

However, if the call is received from a digital telephone that does not have a display device, or if the call is received from a digital telephone that does not have a means to input the calling party's name, called party's name, or the degree of emergency,
As with conventional digital telephones, only a ring tone is produced by a ring signal.

Note that it is not necessary to send all the control signals, and a blank signal with no information can be input and sent as necessary.

In addition, when making a call, it takes a long time to press the call button after going off-hook and entering the calling party's number 1, called party's name, and level of urgency, and the exchange ta3 times out. Otherwise, there is a possibility that the control signal from the telephone 1 will not be received, so if there is a possibility of this, please operate the memory setting button 20 before going off-hook, and then operate the dial 22 and keyboard 18. The control signal is stored in the memory in the signal generation circuit 13, followed by off-hook, the memory read button 21 is operated to read the control signal, and the call button 19 is then operated to initiate a call. All you have to do is force it.

However, the configurations in FIGS. 1 and 2 can be arbitrarily selected depending on the conditions, and in FIG. 3, each step can be replaced or a step can be omitted depending on the situation. The present invention can be freely modified by the woodcutter.

As is clear from the above explanation, according to the present invention, when the telephone makes a call, a selection signal and control signals indicating the name of the calling party, the name of the called party, and the level of emergency are sent to the exchange, and the exchange controls these signals. Add the calling party number to the signal and forward it to the destination exchange,
The terminating exchange transmits the calling party number, the name of the caller, the name of the recipient, and the degree of urgency to the telephone of the terminating party. Since the calling party's name and the called party's name can be known, the burden of mediation on the called party's side is reduced.

(21) Since the calling party's name and the called party's name can be known before responding, it is possible to decide whether to respond or not as necessary.

(3) Since it is possible to know before answering whether or not the incoming call is of a high degree of urgency, it is possible to determine whether to respond or not as necessary, similar to (2) above.

This has a remarkable effect on the operation of digital telephones.
