Abstract

PURPOSE:To attain automatic transfer to an external line by not setting at least one of external lines to external line automatic transfer but setting it to an automatic reply mode and receiving a PB code in the automatic reply so as to receive the PB code by a prescribed dial code. CONSTITUTION:When a connection control circuit 7 receives an incoming call from an external line circuit 2 to an external line, a type set to an external line reached from a data memory 72 is read. When the external line receiving the call is set to the automatic reply mode, a PB code reception circuit 5 is connected to a receiving line of the incoming call external line to prepare the reception of the PB code and an automatic reply circuit 6 is connected to a transmission line to send a reply signal to a transmission line or a transmission channel. A connection control circuit 7 uses a PB code analysis circuit 9 to analyze the received PB code and to execute procedures such as 'automatic transfer setting', 'listening to automatic answering recording', 'designated extension connection', 'data terminal changeover' and 'setting of automatic answering recording'.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention connects at least two telephone lines as external lines and a plurality of lines terminated at a telephone set as extension lines, and connects each of these two external lines as extension lines. The present invention relates to a button telephone device that interconnects lines.

[Conventional technology]

In a general key telephone device, each external line to be accommodated and connected has an independent telephone number, and incoming calls are accepted on the external line according to the telephone number received at the exchange.

The external line automatic forwarding system of the button telephone device registers the Atayal code of the forwarding destination along with the outside line number, and when a call is received on the registered outside line, the call is automatically forwarded to the registered forwarding destination.

Registration for such automatic call forwarding is performed from an extension line.

FIG. 5 is a flowchart showing an example of a procedure for automatic outside line transfer registration. When the button telephone device detects a call from an extension and receives predetermined information indicating a request to set an automatic external line transfer, for example, press operation information of an automatic transfer button at step 531), then (step 532), Steps to set up automatic forwarding (
Setting is executed by step 533). In the automatic transfer setting procedure (S33), for example, an outside line button corresponding to the outside line to be set.

Press the forwarding destination dial code and the settings button in that order.

In a key telephone device in which automatic forwarding of outside lines is set in this manner, when an incoming call is received on the outside line to which forwarding is set, the call is automatically made from another available outside line and the set forwarding destination telephone is called. In this case, the response signal is sent to the calling party after waiting for a response signal from the transfer destination.

FIG. 6 is a flowchart showing an example of a transfer procedure when an incoming call is received on an outside line for which automatic outside line transfer is set. When the button telephone device detects that automatic forwarding is set for the external line that received the incoming call, it checks whether other external lines are available (step 541), and if there is a vacant external line (step 542).
), the process advances to the automatic call procedure (step 543). For example, an automatic call is made by automatically calling one of the available outside lines, retrieving the forwarding destination number from the storage device, and automatically dialing the calling outside line.
file is sent. In this procedure, a response signal is received from the connection destination (step 544)1. The button telephone device connects the external line that received the incoming call and the external line that made the automatic call to form a transfer route, and transfers the response signal from the called party to the calling party (step 545).
to end the automatic outside line transfer procedure.

In conventional key telephone devices, automatic call forwarding is set by specifying an external line by using an external line designation button from an internal line or a tire dial button for operating an external line number, as explained in FIG. Additionally, the designated external line could be a specific line or all lines.

[Problem to be solved by the invention]

As mentioned above, with conventional key telephone devices, you can specify automatic call forwarding settings from your internal line, and you can also set it for all external lines, so even if you try to change the forwarding destination while you are out, you can simply set it from your external line. Furthermore, even if such a procedure were to be set, if automatic forwarding was set for all outside lines, the key telephone device would automatically forward incoming calls, so it would be impossible to call the key telephone device from an outside line. There was a point.

An object of the present invention is to provide a button telephone device that solves the above problems.

[Means to solve the problem]

The present invention provides a button telephone that accommodates and connects at least two telephone lines of an exchange as external lines, accommodates and connects a plurality of lines to which telephones are respectively connected as extension lines, and interconnects these external and internal lines. In the device, at least one of the external lines is designated in advance as an external line set to automatically answer an incoming call, and an incoming call to the external line set to be automatically answered is automatically answered and a push button tire code is received from the calling party. It is characterized by having an automatic response means.

Further, when the automatic answering means automatically answers an incoming call on the automatic answering line (1i), the automatic answering means sends a response value π indicating that the automatic answering line has arrived and that the extension can be called by a predetermined operation. It is characterized by

Furthermore, the button telephone device of the present invention automatically answers an incoming call to the automatic answering set line, and in response to a request from the calling party to set up automatic forwarding of an outside line using a predetermined pushbutton dial code, the outside line number and forwarding are set. The present invention is characterized by having automatic transfer setting means for setting conditions for automatic external line transfer according to the received number when the destination number is received.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In the figure, the button telephone device includes a main switch 1, an outside line circuit 2. Extension circuit 3. Automatic transmission circuit 4°FB code (multifrequency code) receiving circuit 5. Automatic response circuit 6. Connection control circuit 7.
Operation button analysis circuit 8° and PB code (multi-frequency code)
It has an analysis circuit 9.

Main switch l is external line circuit 2. Extension circuit 3. Automatic transmission circuit 4. It houses a PB code receiving circuit 5 and an automatic response circuit 6, and interconnects them under the control of a connection control circuit 7. The outside line circuit 2 is an interface circuit that connects the information on the telephone line of the exchange to the main switch 1 and the connection control circuit 7, and this circuit connects the telephone line to a plurality of general outside lines 21 and one automatic answer setting outside line 22. It is specified. The extension circuit 3 accommodates a plurality of extensions 30 terminated by a telephone set 31, and
This is an interface circuit that connects the above information to the main switch 1 and the connection control circuit 7. The automatic calling circuit 4 activates the calling line in the case of abbreviated dialing, final dial code retransmission, etc., and sends the dialing code received from the connection control circuit 7 to this calling line.

The PB code receiving circuit 5 receives the PB code via the main switch l and sends it to the connection control circuit 7. The automatic answering circuit 6 connects to the incoming outside line and automatically answers the call. Normally, an automatic response sends a response message to the calling party.

The connection control circuit 7 has various functional procedure programs 71 and various data memories 72, and processes call connection control by making full use of the programs and data according to input information. The operation button analysis circuit 8 receives an extension 30. from a telephone 31 housed and connected to the button telephone device. Extension circuit 3. The operation button information is received via the connection control circuit 7, analyzed, and notified to the connection control circuit 7. The PB code analysis circuit 9 inputs and analyzes the PB code received by the PB code receiving circuit 5, and transmits the PB code to the connection control circuit 7.
\Notice.

The program 71 for various functional procedures includes, for example, the operating procedures described later in FIG. 2 and subsequent figures, and the various data memories 72 include, for example, a setting memory for outside line types, a transfer destination number memory, and the like.

Although the automatic calling circuit 4 and the automatic answering circuit 6 are illustrated and described as being connected to the extension line and outside line via the main switch 1,
The calling signal, answering signal, and dialing code may be connected via the connection control circuit 7 using the initial code without using the main switch 1.

The difference in FIG. 1 from the conventional system is that an automatic response setting outside line is designated as the outside line.

Next, the main operating procedures in FIG. 1 will be explained with reference to FIG. 1 along with the flowcharts of FIGS. 2 to 6.

FIG. 2 is a flowchart showing an example of the main operation procedure according to FIG. 1, and FIGS. 3 to 6 are flowcharts showing examples of partial details of FIG. 2.

In FIG. 2, when the connection control circuit 7 detects an incoming call from the outside line circuit 2 to an outside line (step Sl), it first reads the type set for the received outside line from the data memory 72 (
Step S2). If it is an outside line without special settings, the connection control device 7 lights up the lamp of the incoming outside line and sounds a ringing signal to the telephone 31 via the extension circuit 3.

If the incoming external line is set to auto-answer, the auto-answer procedure in step S3 is executed. FIG. 3 is a flowchart showing an example of an automatic response procedure.

In FIG. 3, the connection control circuit 7 that has read the automatic response setting of the incoming external line connects the PB code receiving circuit 5 to the receiving path of the incoming external line and prepares to receive the PB code (step 5ll). The automatic response circuit 6 is connected to the sending path and a response signal is transmitted to the sending path or the transmission path (step 512). Since the response signal forms a communication path from the calling terminal, the automatic response circuit 6 sends a response message, such as "This is ○○. This line is set for automatic response, so go to number XXXX. Please fix the call.'' (step 513). General callers, including rotary-dial telephones, will be answered with this answer message. However, for example, callers who can send a pre-assigned dialing code using a PB code can use dialing to set up automatic forwarding from outside the home, set up and listen to answering machine recording from outside the home, connect to a designated extension, etc. , the connection control device 7 receives the PE code from the PE code receiving circuit 5 (hand 1s1
4) and ends step S3 in FIG.

The connection control circuit 7 analyzes the received PE code using the PE code analysis circuit 9 (step S4), and determines, for example, "automatic transfer setting".
(Step S5), ``Listening to answering machine recording'' (Step S8), ``Designated extension connection J (Step S9),'' ``Switching data terminal,'' and ``Setting answering machine recording'' are executed.

FIG. 4 is a flowchart showing an example of the automatic transfer setting procedure of step S5 in FIG. In FIG. 4, when the received PE code is analyzed as a setting for automatic forwarding of an outside line, the connection control device 7 further receives an outside line number and a forwarding destination number to be set from the FB code receiving circuit 5 (step 521). The caller, for example, r#01j (external call forwarding setting), "#13
・14” (two external numbers), r*23-4567j
Continuously press and dial (forwarding destination number).

By writing the received numbers into a predetermined area of the data memory, the connection control circuit 7 sets, for example, the automatic transfer designation information and the forwarding destination number in the type setting area of the two received external line numbers (step 522)L. A signal indicating the end of the setting, for example, a special tone, is sent (step 523) to notify the caller of the end. This notification causes the caller to disconnect, so the connection control circuit 7 stops the termination signal being sent to the called external line (in this case, the automatic answer setting external line 22) (step 524) and restores the call. This setting can be confirmed, for example, by calling the set outside line.

If the setting read in step S2 in Figure 2 is automatic transfer, use the automatic transfer procedure (step 56) (explanation method) in Figure 6, or the answering machine recording procedure (step 57) (detailed explanation). (omitted) is executed.

A detailed explanation of the execution steps S8 and S9 analyzed in step S4 of FIG. 2 will be omitted.

In this embodiment, the external line set for automatic answering may be an incoming call-only external line in case of a button telephone device that accommodates large-capacity external lines, but it is usually a line that prohibits external line automatic forwarding of incoming calls, and the general external line is set to external line automatic forwarding. It will likely be used for automatic outgoing lines in many cases.

〔Effect of the invention〕

As explained above, according to the button telephone device of the present invention,
By not setting at least one external line to automatic forwarding, but always setting it to automatic answering, and configuring it to receive a PE code when automatically answered, the external line will receive a PE code with a predetermined dial code. The operational improvement effect is that it is possible to set up automatic forwarding.
