Abstract

PURPOSE:To send a dial signal by providing a dial signal transmitting means to send a dial signal corresponding to a function action through an extension to a telephone system at the time of operating the operation switch and operating the operation switch only one time. CONSTITUTION:A dial signal to operate a holding operation function with a telephone system 1 is '7'. When an operation switch SW1 corresponding to the holding operation of any function dial unit 12 is pushed, an arithmetic control circuit 14 decides the holding operation based on the operation detecting signal from an operation detecting circuit 13, drives a relay Ry1, closes a contact r1, simultaneously, drives a relay Ry2, opens a contact r2 and separates a telephone set connected to an extension 5. Next, the relay Ry1 is turned on and off seven times, and seven pulses are sent by the opening and closing of the contact r1. When the sending of the dial signal is completed, the contact r1 of the relay Ry1 is opened and simultaneously, the contact r2 of the relay Ry2 is closed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a functional dialing signal 1 for transmitting a dialing signal for operating the telephone switching function of a telephone switching device.

[Prior Art] Recently, in order to improve the convenience of telephone calls, consideration has been given to telephones that are equipped with functions such as temporarily holding a call, talking with a doorbell, and talking between extension lines.

Figure 4 is configured not as a telephone but as an atapuata.
2 shows the circuit configuration of a telephone device equipped with the functions described above. To this telephone device 1, an outside line 2 from a telephone office is connected, a telephone line 4 from a door intercom subunit 3 is connected, and a telephone 6 is connected to each of the telephone devices 1. A plurality of connected extensions 5 are connected.

The telephone device 1 includes an incoming call detection unit 7 that detects an incoming outside call, a hold circuit 8 that puts the outside line 2 on hold, and the outside line 2 and an extension 5, between the extensions 5 and 5, and the call line 4 and the extension 5 of the intercom slave unit 3, respectively. 1, a main control circuit 10 for controlling each of the circuits 7, 8, and 9, and a power supply circuit 11 for supplying power to each of the circuits 7 to 10.

In this telephone device 1, exchange function operations such as hold operations and extension calls can be set and canceled by operating keys on the telephone 6 connected to the extension.

[Problems to be Solved by the Invention] However, as the number of exchange functions increases, the number of dial operations for setting and canceling the operation of the exchange functions increases, resulting in a problem that key operations become complicated.

The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a function dial that allows easy setting and cancellation of exchange function operations such as hold and extension calls without having to operate keys on the telephone. The unit is on offer.

[Means for Solving the Problems] The present invention provides a connection switching function that connects at least an outside line and an extension line, connects the outside line and the extension line when an outside line call is received or makes an outside line call, and connects the extension lines when an extension call is made, and a hold operation. Equipped with telephone exchange functions such as a hold function that sometimes places outside calls on hold,
A telephone device connected to the extension line between the telephone and the telephone device that uses a signal from the extension side as a dial signal for the telephone connected to the extension to instruct the setting and release of the telephone elevated function operation such as extension calling, hold operation, etc., and performs the telephone switching function. It is equipped with operation switches corresponding to each operation, and dial signal transmitting means for transmitting a dial signal corresponding to the function operation to the telephone device through an extension line when the operation switch is operated.

[Function] Therefore, when setting each operation of the telephone exchange function of the telephone device, the function dialing unit of the present invention operates the operation switch provided corresponding to each function such as extension calling, hold operation, etc. , a dial signal for setting or canceling the corresponding function operation is sent to the telephone device. In other words, since a predetermined dial signal can be transmitted with a single operation of the operation switch, it is easy to set or cancel a function operation.

[Embodiment] FIG. 1 shows an overall view of the state in which the function dial units 12 of the present invention are inserted and connected to the extensions 5 connecting the telephone device 1 and each telephone 6, and each function dial unit 12 exposes the push button type operation switch SW1.

Fig. 2 shows the configuration of the function dial unit 2, in which the operation switch SW1 corresponding to the function operations such as hold, general call, door phone call, etc. is connected.
3, a dial relay R3'+ for sending a dial signal, a relay Ry2 for disconnecting the telephone 6 connected to the extension 5 from the extension 5, and these relays R3. '1. It is composed of an arithmetic control circuit 14 that controls R3'2.

Next, the operation of this embodiment will be explained.

First, if the dial signal for operating the hold operation machine event in the telephone device 1 is set to "7", which function switch SW1 corresponds to the hold operation of the dial unit 12?
When pressed as shown in FIG. 3(a), the arithmetic control circuit 14
is determined to be a pending operation based on the operation detection signal from the operation detection port I¥813, and first drives the relay Ry1 as shown in FIG. is closed, and at the same time, as shown in FIG. 3(), relay Ry2 is driven to open its relay contact and disconnect telephone 6 connected to extension 5.

Next, the dial relay R3'1 is turned on and off seven times in response to the dial signal "7" corresponding to the hold operation, and seven pulses are sent out by opening and closing the relay contact r1. When the transmission of the dial signal is completed, the relay contact r1 of the dial relay RY+ is opened, and at the same time, the relay contact 1-2 of the relay Ry2 is closed.

As described above, the function dialing unit 12 is inserted into the extension 5 between the telephone device 1 and the telephone 6, and sends a dial signal to each function to give instructions for setting and canceling the switching function operation provided in the telephone device 1. A predetermined dial signal can be sent to the telephone device 1 by pressing once the operating switch SW1.

[Effects of the Invention] The present invention provides a telephone device, an operation switch connected to an extension line between the telephone set, which corresponds to each operation of a telephone exchange function, and a switch corresponding to each function operation when the operation switch is operated. Since it is equipped with a dial signal transmitting means for transmitting a dial signal to the telephone device through an extension, it is possible to transmit a dial signal instructing the switching function operation of the telephone device by pressing one operation switch, which improves operability. Second, even if the number of functions increases, there is no need for complicated operations such as those on a telephone, so it has the effect of ensuring convenience.
