Abstract

PURPOSE:To attain connection with other lines after an external incoming call is connected by connecting other line and a line connected to an external incoming call in response to a predetermined specific external signal after being connected with one of lines. CONSTITUTION:When talking from a key telephone dial telephone set 10 at the outside of a private branch of exchange 1 is transferred to a line 2 by the operation of the operator, the call is connected to the telephone set 10. After the connection, when the dial of the caller is a specified dial such as 'command of acquisition of line 6', a control section 8 controls a line acquisition circuit 7 to acquire the line 6 and to control a line connection section 9 thereby connecting the lines 2 and 6. The line 2 is connected in response to an external incoming call and the line 2 is connected to the other line 6, then even after the external incoming call is connected, the connection with other line is attained by external dialing.

Description

3. Detailed Description of the Invention Technical Field The present invention relates to a telephone terminal device, and more particularly to a telephone terminal device accommodating a plurality of lines.

BACKGROUND ART Conventionally, as a telephone terminal device of this type, there is a transfer telephone device, and the transfer telephone device accommodates a plurality of lines. Telephone numbers of forwarding destinations are registered in advance in each of the plurality of lines, and when a call arrives from the outside on one line, the incoming call from the outside is connected to the forwarding destination registered on that line.

In this way, with conventional telephone terminal devices, incoming calls from outside are only connected to one line, such as with forwarding telephone devices.
That is, it has the drawback that it can only be connected to a fixed line, such as a transfer destination, and after this connection, it is impossible to connect to another line by dialing from an external caller.

The present invention was made in order to eliminate the drawbacks of the conventional ones as described above.After an incoming call from outside is connected to one line, it is connected to another line by a specific signal (dial) from outside. The purpose is to provide a telephone terminal device that can be connected to a line.

11 Standan 1 The telephone terminal device according to the present invention is a telephone terminal device that accommodates a plurality of lines, and when one of the lines is connected to the external telephone in response to an incoming call from the external telephone, The present invention is characterized in that one of the lines is connected to the other line corresponding to the previous two specific signals in response to a predetermined specific signal from an external telephone.

Embodiment Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. In the figure, private branch exchange 1 accommodates line 2.6,
The line rA2 has an incoming call detection section 3, a line acquisition circuit 4, and a push button Daicel signal reception section 5, and the line 6 has a line acquisition circuit 7. A control section 8 and a line connection section 9 are provided between the lines 2 and 6.

Push-button dial telephone 1 located outside the private branch exchange 1
When a call from 0 is transferred to line 2 by an operator's operation, a ringing signal is sent to line 2. Incoming call detection section 3
Then, this call signal is detected and the incoming call detection signal is sent to the control unit 8.
The control unit 8 uses this incoming call detection signal to control the line acquisition circuit 4 to respond to the incoming call to the line 2, and connects the external push-button dial telephone 1! ! Connect to 10.

After this connection, when the caller dials the push-button dial telephone 10, a push-button dial signal is sent to the line 2, and this push-button dial signal is received by the push-button dial signal receiver 5 and sent to the control section 8. Ru.

If the caller's dial is a predefined dial indicating "line 6 capture 1h", for example, l'masu 1J, the controller 8 controls the line capture circuit 7 to capture the line 6, and also controls the line capture circuit 7 to capture the line 6. The connection unit 9 is controlled to connect the lines 2 and 6.

After the connection between line 2 and line 6, the caller's dial is filled with a pre-defined dial that says "Line 6 release instruction", for example, "
If the line is 2, the control unit 8 controls the line capture circuit 7 to release the line 6, and also controls the line connection unit 9 to disconnect line 1!2 and line 6.

After the line 6 is released, if the caller's dial is a dial specified in advance for "line 2 release instruction", for example, "arrow 3", the control unit 8 controls the line capture circuit 4 to release the line 2. let go.

Between connecting lines 2 and 6 and disconnecting them, the caller freely sends push-button dialing signals to private branch exchange 1 through line 6, which only the extension of private branch exchange 'Ia1 has. You can use functions (speed dialing, calling individual extensions, etc.).

In this way, in response to an incoming call from the outside, connection is made to line 2, and after this connection, a predetermined specific signal (
By connecting this line 2 to another line 6 in response to a predefined dial (predefined dial), even after an incoming call from outside is connected to one line 2, it is possible to connect to another line by dialing from outside. Connection can be made possible.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, after being connected to one of the lines in response to an incoming call from the outside, the connection is made to one of the lines in response to an incoming call from the outside in response to a predetermined specific signal from the outside. By connecting the connected line and Iya's line, there is an effect that even after an incoming call from the outside is connected to one of the lines, it can be connected to the other line by dialing from the outside.
