JPS58168394A - Pulse dialler having hooking function - Google Patents

Abstract

PURPOSE:To attain a hooking function independent of perception, by using one of unused keys of a pulse dialler as a key to be exclusively used for hooking. CONSTITUTION:When a telephone call from a line wire is able to temporally hold and connectable to an extension, the exclusive hooking key is previously depressed. Information indicating a code to be exclusively used for hooking is sent from a key interface 21 to a control part 24. Receiving the hooking information, the control part 24 calculates the number of pulses to be outputted from the natural oscillation frequency of an oscillator 29 and hooking brake time, specifies an output counter 23 to output pulses, and turns off a transistor Q only for the hooking brake time.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a pulse end earer with a hookendar function, and more particularly to a pulse end earer with a seven kinder function used in a private branch exchange.

(2) Technical background Telephones are broadly divided into two types: gusset phone type and rotary dial type.
The pulse diamond according to the present invention has the characteristics of both types. In other words, the key operated by the Cabinet member is a pushbutton type, but when this key is pressed, the electrical operation is a rotary dial type operation as shown in Figure 1.
'' If you press the key, the voltage E [V] will begin to drop from d indicated by the broken line when your finger leaves the key.■

■, ■0 Three pulses are generated.

As a result, the P telephone line system detects that a person presses the "3" key, but the specific operation is as follows: Reference symbol B is called a break, and each key is connected to the 9th integration gate. This is done by turning on and off the Tokunzo Star Sui and Ji according to the number of break BOs. Therefore, while the pulse seven-turn dial type shown in Fig. 1 generates the pulse mechanically, the pulse tire type generates the pulse electronically using the two transistor switches.

When using a pulse dialer type O-electronic machine that performs this type of operation as a private branch exchange, it is necessary to place calls on hold from outside.
A hooking operation is required to temporarily stop Kj1wi in the transfer O.

This hooking Kl! The time ts is jllllEI, where t is the disconnection time of the telephone, and tl is the break waiting time during which the %Δ pulse is falling, then tr<ts<ts
It must be in the range of 0@ll0tst, and the 9th exchange system is operated by 70@OA Luss and is designed to send a predetermined local telephone Km.

(3) Conventional technology and problems Conventionally, a large hook switch was set up separately, but a person could press it with his or her finger 7 times! Friend, go through the motions.

However, if the time to press the hook switch is too short, the exchanger will misunderstand the break waiting time in Figure 1 and perform an action similar to pressing the RLJ key.On the other hand, if the hook switch is pressed too long, the disconnection time will be 1.
W4 agrees.

, '11 As described above, the 7-calling operation must rely solely on human intuition, resulting in the problem that conventional pulse-diameter type 2 telephones and 9-private branch exchanges often malfunction, resulting in extremely low communication efficiency. There was a point.

(4) Purpose of the invention The purpose of the present invention is to provide one of the currently used pulse dialers.
By using one of the two unused keys as a dedicated key for 7 Kinda), the purpose is to improve the call efficiency of the exchange by performing accurate hooking operations without relying on human intuition. .

(5) Invention O Configuration According to the present invention, key interfaces 7 and 8 connected to numeric keys and hooking keys, a memory in which numbers corresponding to the numeric keys are stored, and an output counter connected to a switching element are sequentially provided. A control unit is connected between the key interface and the output counter, and is connected to a control unit that inputs information regarding the numeric keys and the 7-key key and gives commands to the memory and output counter. An arm dialer with a seven-way dialer is provided, characterized in that it is provided with an output counter and a oscillator for forming a timing clock sent to a control section.

(6) Embodiment of the Invention FIG. 2 is a diagram showing the arrangement and configuration of the hooking function/4-rus end earler 2 according to the present invention.
Terminals A and Bf: diode preamplifier connected to a private branch exchange (not shown) 1, receiver 31, and transmitter 32t.
- By pressing the C key, a pulse corresponding to the number of circles is output when the p key is pressed, turning on and off the transistor Qt, and disconnecting the line between the exchange side and the telephone side. It is about to be done.

The hooking function-equipped ΔRuss earler 2 according to the present invention is the third
The key reference numeral 21 having the configuration shown in the figure has a key interface of Ton, the vertical and horizontal directions are L. to .04, and the horizontal and vertical directions are L. to H. The key interface is 12 keys in total.

The memory 22 has the role of storing keys input from the decoder of the key interface 21 and instructions from the IIJ controller at a predetermined address. The output counter 23 outputs a number of pulses corresponding to the input from the memory 22 to the transistor Q, thereby turning the transistor Qt on and off. The I control unit 24 inputs information specific to the pressed key from the key interface 21, such as the code of the key, whether it is a numeric key from 0 to 9 or 7, a king-only key, and in the case of a numeric key, the write address. By giving a command to the memory via the counter 25, read address counter 26, or address selector 27, or by giving a command directly to the output counter in the case of a hooking-only key, a predetermined number of data can be input from the output counter 23. /Yarst Sends to transistor Q.

The oscillation 929 can be formed, for example, by a crystal oscillator, and activates the counter 28t to send a timing clock to each of the above sections.

The pulse end earer 2 having the above configuration operates as follows.

When entering a normal telephone number using the keys, if the "0" key is pressed first, the key interface 21 will tell you that it is "0" and that it is a numeric key.
One piece of information is sent to the memory 22 and the control section 24. Control [i24 sends the address of the memory 22 yen in which rOJ should be convoluted to the memory 22 via the write address counter 25 and address selector 27, and sets "0" to the mosquito address.
to be stored. In this case, when 10 rOJs are lined up in the memory and are stored in the 0th order, the control unit 24 sends rOJs sequentially from the first address where "0" is stored via the read address counter 26 and address selector 27.
1 is read out and sent to the output counter 23, and a command is sent to the #output counter 23 to send 110 pulses to the transistor Q. Accordingly, transistor Q is the first
) 4 Rus waves 7! The rake time t1 is set to be intermittent 10 times, and communication to a predetermined other party is possible.

Next, if you receive a call from outside and want to temporarily connect to the extension, set a non-numeric key as a hook-only key in advance, press that key, and press key 7, 8, 21. is the code of the key dedicated to hooking, and the information that it is hooking is transmitted to the control unit 24.
sent only to

7. The king's break time (Figure 1) varies depending on the speed of the alternation, but is approximately 0.5 (S) to 1 [S]. The control 1s24 that receives the above hooking information is the oscillator 29.
The number of pulses to be output is calculated from the natural oscillation number and the hooking break time, a designation is given to the output counter 23 to output a pulse, and the predetermined 7. The transistor Qt is turned off for the king break time.

(7) Effects of the Invention According to the present invention, one key of the pulse dialer is used as a dedicated key for t7y king, thereby relying on the intuition between Sims, and pressing the cough key does not necessarily cause the hooking break time. Since the switching transistor is turned off,
In addition, the switching machine does not malfunction and the effectiveness of communication can be improved.
