Abstract

PURPOSE:To realize various kinds of service such as a voice call, a self response by the telephone set of a destination given beforehand the remote operation of a holding state by an operator and the like, by shifting a designated telephone set indicated in a data string having received the data string sent to a telephone line from a multiple-connected telephone set, etc., to a designated service state. CONSTITUTION:It is assumed that the contents of the button operation of No.1 telephone set are to shift No.3 telephone set to an onhook holding mode. When No.3 telephone set inputs the data string sent to the telephone line by a data reception circuit 21 through a data input part 9, and a CPU 1 decides that a part more than 2/3 of received data is set data, the CPU 1 supplies a base current to a transistor Q2 so as to make its own telephone set acquire the telephone line 8. Further, it starts a holding tone generator 22, and simultaneously, by sending a control signal to a speech IC 4, it sends the holding tone to the telephone line 8 and a speaker 51, and makes the telephone set shift to the on-hook holding mode. Thus, the operator of No.1 telephone set can hold No.3 telephone set, and can re-start communication by No.3 telephone set after isolating No.1 telephone set from the telephone line and moving over himself.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a plurality of telephones connected to a pair of telephone lines in a plurality of telephone lines, each of which has a data receiving function that transitions to various states depending on data input via the telephone line. Regarding telephones.

[Conventional technology]

In button telephone devices in which the main device and multiple button telephones are wired in duplex or star wiring using a speech line and a control line, control data is sent and received between the main device and the individual button telephones via the control line. . In this case, in response to control data sent from the main device via a control line, the key telephone simply displays a call or a line usage status.

[Problem to be solved by the invention]

When connected to a telephone line, this unit can perform general operations such as making and receiving calls.When multiple individual telephones are connected to a pair of telephone lines in multiple ways, it is possible to perform various operations on these individual telephones. There is a request to start it remotely.

The purpose of the present invention is to send control data from a telephone or an exchange connecting the telephone lines to a pair of telephone lines, and to specify a single telephone that is specified by the control data among the single telephones that receive the control data. The goal is to transfer the service to a new state, that is, to transfer the service.

[Means to solve the problem]

Therefore, the configuration of the present invention is as follows.

In a plurality of telephones connected in a dual manner to a pair of telephone lines, the telephone in a standby state receives a data string superimposed on the direct current voltage of the telephone line; A telephone with a data receiving function, characterized in that it is provided with means for determining that the data has been sent to a telephone, the state of the telephone indicated by this data string, and shifting the own telephone to the determined state.

〔Example〕

FIG. 1 is an operational flow diagram of a standalone telephone with a data receiving function (hereinafter referred to as a telephone) which is an embodiment of the present invention.

FIG. 2 is a circuit diagram of the telephone shown in FIG. FIG. 3 shows the data that the telephone inputs from the telephone line.

1 is a central processing unit, 2 is a backup power supply, 3 is a power supply circuit, 4 is a speech ICl3 is a handset, 6 is a hook switch, 7 is a bridge diode, 8 is a telephone line, 9 is a data input section, 21 is a data reception 22 is a hold tone generator, and 51 is a speaker.

First, the contents of the data string shown in FIG. 3 sent to the telephone line by the transfer source that transfers the service are as shown in Table 1. Here, an example is shown in which three telephones are connected to one pair of telephone lines 8.

In addition, as an example of data, as shown in Figure 3, 8-bit data from D0 to D7 is repeated three times, and this series of data strings is repeated three times.
It is repeated twice to make one cycle.

Next, the operation of the telephone will be explained based on the operation flow diagram of FIG.

One of the telephones connected to a pair of telephone lines in a dual manner, for example No. 1, is holding the dial button 6 while the telephone
Suppose you press . In this case, the central processing unit (hereinafter referred to as CPU) 1 is in the process of capturing the telephone line, so it does not judge it as dialing, but judges it as a service transfer operation, and sends the 8-bit data No. 6 corresponding to button 6 to the telephone line. Send.

N, which is connected to the same telephone line 8 as the telephone No. 1
The telephones No. 002 and No. 3 detect the data string sent from the No. 1 telephone at the data input section 9 . CPU
I determines that its own telephone is in a standby state, inputs a data string from the receiving circuit 21, and when 2/3 of the received data matches a preset value, causes the telephone to perform a preset operation. let

As shown in Table 1, there are two contents that the setting data indicates.
One is for which telephone, and the other is for what kind of function the corresponding telephone is to perform.

Since the transferred data number is 6, the setting data is 8-bit "10010011", which indicates that the telephone number No. 2 is to be placed in speaker listening mode.

Therefore, when the CPU of the No. 2 telephone determines that it has received this setting data, it supplies the base current to the transistor Q2 to operate it, and as a result, the transistor Q1 operates, and as a result, the No. 2 telephone captures the telephone line 8. C.P.
The UI further controls the speech IC 4 to transition the telephone to speaker listening mode. Therefore, it is also possible to make a voice call from the telephone No. 1 to the telephone No. 2.

If the button operation on the telephone No. 1 was dial button 9 instead of dial button 6, the 8-bit setting data corresponding to data No. 9 would be "1001101".
1". This setting data is for transitioning the telephone No. 3 from Table 1 to on-footer hold mode. As shown in Figure 3, this data string sent to the telephone line is 273 or more of the received data is input by the receiving circuit 21 through the data input section 9, and the received data is the setting data and C.
When the PUI makes the determination, the CPUI supplies base current to Q2 to cause its own telephone to seize the telephone line 8. Furthermore, by activating the hold tone generator 22 and sending a control signal to the speech IC 4, the hold tone is sent from the speech IC 4 to the telephone line 8 and the speaker 51, and the telephone is shifted to the on-footer hold mode. In this way, the operator of telephone No. 1 puts telephone No. 3 on hold, disconnects telephone No. 1 from the telephone line, and moves the telephone No. 3 himself.
It is possible to resume a call using the same phone.

Other service functions not shown in the table can also be transferred to a desired telephone by increasing the types of setting data and adding corresponding CPUI processing.

In the above example, the transfer was performed using the No. 1 telephone, but it may be performed using any telephone. Also, the device that performs the transfer is not limited to telephones (it may also be a switchboard or various control boxes connected to the telephone line).

〔Effect of the invention〕

As explained in detail above, the data receiving function telephone according to the present invention is capable of receiving data strings transmitted from duplex-connected telephones, etc. to the telephone line by connecting a plurality of telephones to the telephone line. Since the designated telephone set shown in the column transitions to the designated service state, it is possible to make a voice call, perform self-answering on the telephone that has been remotely controlled by the operator in the hold state, and perform various other services, making it convenient. This enables a variety of uses.
