JPS59194555A - Dial output device of subscriber's telephone set - Google Patents

Abstract

PURPOSE:To perform dialing precisely and easily by storing the operated contents of a pause button in a memory and applying the stored contents in a pause circuit. CONSTITUTION:The titled device is provided with the memory 6 storing the contents of dialing, the pause circuit 13 inhibiting a dial output until passing the pause time and the pauses button 2 actuating the circuit 13. The operated contents of the pause button 2 are stored in the memory 6 and the operated contents of the pause button 2 which are stored in the memory 6 are applied to the circuit 13. Cosequently, a calling subscriber can continue dialing independently of the passage of the pause time, so that the dialing operation can be performed precisely and easily.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dial output device in a subscriber's telephone set ζ.

For example, when making a call from an internal line to an external line at work, l
This exchange requires a pause release for line exchange and connection. Therefore, caller e cannot perform the next dial operation until this pause time has elapsed. In addition, there is generally no way to confirm the elapsed pause time by the dial tone heard from the handset.
If the next dial output operation is performed by mistake before the dial tone is heard, the dial operation may be invalidated. Therefore, for the caller, this pause time feels very long, and the dialing operation becomes troublesome.

The present invention enables a caller to perform dialing operations continuously regardless of the passage of pause time, for example, when making a call from an internal line to an outside line, and to perform dialing operations reliably and easily. With the goal.

Hereinafter, the present invention will be explained in detail based on an embodiment shown in the drawings.

The figure is an overall circuit diagram of this embodiment. In the figure,
11ri is a keyboard in which numerical keys etc. are arranged in a matrix, 2 is a pause button for performing a pause operation, and 3 is a crystal oscillation element. 4 is a one-chip IC including a circuit to be described later, and the keyboard 1, pause button 2, and crystal oscillation element 3 can be externally connected to this IC4. This IC4
In the figure, 5 is a keyboard logic that outputs signals corresponding to the operations of the keyboard 1 and the pause button 2, and 6 is a memory that stores the output of this keyboard logic 5, that is, the contents of dial operations. 7 is a write address generation circuit that provides a write address to the memory 6 in synchronization with the output timing of a timing generation circuit 9 that responds to the output of the reference oscillation circuit 8; This is a read address generation circuit that provides an address. 12 encodes the output of the memory 6 and sends the encoded output to the output circuit 11 (
This is an instruction decoder.

Reference numeral 13 denotes a pause circuit, which receives the output of the command decoder 12 and outputs the content of this output to the bead button 2.
The pause control circuit 14, the pause counter 15, and the pause clock generation circuit 16, which form a pause control output when the operation includes an operation of The pause counter 15 starts counting upon receiving the control output from the pause control circuit 14, and the count amplifier is turned off by the clock signal, and when a predetermined count is reached, a count end signal is generated. is applied to the output circuit 11 and the read address 10.

The output circuit 11 prohibits the output of the memory 6 from being output as a dial output while the pause counter 15 is in counting operation.
Carry is prohibited during the counting operation, and this prohibition can be canceled by applying the count end signal. Note that 17 is a mute output circuit that receives the output of the pause counter 15 and generates a mute output when the pause counter 15 is in counting operation.

This mute output circuit 17 is for muting unnecessary sounds from the handset during pause so that they are not heard. The dial output in this embodiment may be either a tone dial or a pulse dial.

Therefore, when each caller is making a call from within the company to outside the company, for example, press the [-0] key for making an outside call, then press pause button 2, and then press the pause button 2. You can press the keys corresponding to the numbers. As a result, the calling party will not be unable to perform the next dial operation due to the pause time when passing through the exchange, and the dial operation will become convenient and easy. Also, since the pause operation is performed via memory, pressing pause button 2 twice in a row will take twice the pause time, and pressing it three times in a row will take three times the pause time. Depending on the number of times you press the pause button, you can set the pose time for Ren and Rumi.

According to the present invention, a memory for storing the contents of dial operations, a pause circuit that prohibits the output of the dial until the pause time has elapsed, and this pause circuit are created. It is equipped with a pause button for movement, stores the operation contents of the pause button in memory, and supplies the operation contents of the pause button from the memory to the pause circuit. For example, if you make a call from an internal line to an outside line without waiting for the pause time to elapse, you can perform a series of dial operations. The dialing operation is no longer invalidated, and the dialing operation becomes very convenient and easy for the caller.
