Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an electronic button telephone device with a selective transfer function, and in particular accommodates lines that can be transferred by sending a hooking signal and lines that cannot be transferred by sending a hooking signal. The present invention relates to an electronic button telephone device with a selective transfer function that enables transfer.

[Conventional technology]

Conventionally, this type of electronic button telephone device with a selective transfer function was
As a function for transferring external lines, there are some that have only the function of sending a hooking signal to an external line, and as a function similar to sending a hooking signal, they have a function of connecting two external lines and one internal line. However, this feature could not be extended to transfer.

[Problem that the invention seeks to solve]

The above-mentioned conventional electronic button telephone device with selective transfer function is
Since the transfer function sends a hooking signal to an outside line, it cannot be forwarded unless the outside line is accommodated in a PBX extension, and similar calls with two outside lines and one extension require one key phone. It has the disadvantage that it must be in a talking state and the operation is complicated.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an electronic button telephone device with a selective transfer function that solves the above-mentioned drawbacks.

[Means for solving problems]

The electronic button telephone device with a selective transfer function of the present invention has two types of external lines: lines that can be transferred as external lines (lines that can be transferred by sending hooking signals and dialing signals, such as PBX extensions) and lines that cannot be transferred (lines that cannot be accommodated in a PBX, etc. line)
an electronic key telephone device with a selective transfer function, which includes: an incoming call detection section that detects the presence or absence of an incoming call signal from the outside line; an outside line interface section that performs line control of the outside line; a switch section that performs exchange; This device 3 controls a holding tone section that generates sound, an outside line type setting section that sets an outside line type, a telephone interface section that exchanges voice and data with a key telephone, and a key telephone connected to the interface section. When a call is received from an outside line, the incoming call detection unit detects the incoming call and transmits the incoming call detection signal to the central control unit. When the central control unit detects the button operation to ring and capture an outside line on the telephone, the voice signal path of the outside line interface, switch, and telephone interface is connected to answer the incoming call, and when the call is made, the transfer button on the telephone is activated. According to the operation, the outside line type setting unit transfers calls from the outside line to lines that can be forwarded by sending hooking signals and dial signals to the outside line, and calls from outside lines that cannot be forwarded to lines that cannot be forwarded. The system is configured to put the outside line on hold, capture an unoccupied outside line among transferable outside lines, send a dial signal, and after obtaining a response from the transfer destination, connect the voice path of the outside line and the held outside line and transfer the call. Ru.

〔Example〕

Next, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an electronic button telephone device with a selective transfer function according to an embodiment of the present invention.

Referring to FIG. 1, the present embodiment includes an incoming call detection section 1 that detects the presence or absence of an incoming call signal from an outside line, an outside line interface section 2 that performs line control of the outside line, a switch section 3 that performs exchange, and a hold tone. an on-hold tone section 4 that generates an external line type, an outside line type setting section 8 that sets an outside line type, a telephone interface section 5 that exchanges voice and data with a key telephone, a key telephone 6, and a central control section 7 that controls the entire system. It is composed of: The number of outside lines consisting of transferable circuit lines and non-transferable lines and the number of internal lines including key telephones may be arbitrary, and the number of incoming call detection sections IA-IN, external line interface sections 2A to 2N, or telephone interface sections 5A to 5A may be set accordingly. 5M and the number of button telephones 6A to 6M. Further, although the outside line type setting section 8 is connected to the central control section 7, it may also be included in the external interface section 2 or the central control section 7, or as stored data included in the switch section 3 or the central control section 7. realizable. When storing data, button data from button telephones a6A to 6M are converted and set.

Next, the features of the present invention will be explained using FIG. First, when a call arrives from an outside line, the call detection units IA to IN detect the call and notify the central control unit 7 of the call.

Thereby, the central control section 7 controls the telephone interface section 5.
A signal is sent to the button telephones 6A to 6M via A to 5M, and a ringtone is sounded. Operator uses button telephone 6A~
When one of the external line interface units 2A to 6M performs an outside line capture operation by operating its button, the central control unit 7 detects this, controls the switch unit 3, and connects the corresponding one of the outside line interface units 2A to 2N with the telephone set interface. The corresponding voice path of one of the units 5A to 5M is connected to respond to the incoming call.

Next, we will discuss transfer. When the central control section 7 detects that the transfer button of the key telephone has been operated during a call, the transfer operation is determined by the settings of the outside line type setting section 8. If the outside line you are calling is a transferable line,
A hooking signal is sent to the outside line during a call, and a dial signal is sent to the outside line by dialing from the button telephone. On the other hand, when the outside line in use is a non-transferable line, the switch section 3 is switched to connect the outside line to the hold music section 4 to put it on hold, and then captures an empty outside line that is connected to a transferable circuit. By dialing the key telephone, a dial signal is sent to the captured outside line, and after a response is received from the other party, the outside line is connected to the voice bus of the previously held outside line, and the call is transferred. Also, regarding the release of the outside line, if there is a signal indicating that the other party is open on either of the two connected outside lines, it can be detected and recognized that the outside line is open.

In this embodiment, a zero-fold electronic button telephone device is used, which assumes that the call will be transferred to an outside line that is not accommodated by the present electronic button telephone device, whether the call is on a transferable line or a non-transferable line. If you need the function to transfer to a line that cannot be forwarded when you are talking to another key phone in the PBX, use another button operation to make the transfer function the same as transferring a call from a line that is not accommodated in the PBX extension, etc. You can also do it. In this embodiment, a case has been described in which a call is transferred when an incoming call is received, but transfer when an outgoing call is made can also be realized by a similar operation.

〔Effect of the invention〕

As explained above, the present invention is equipped with an outside line identification setting section, sets the type of outside line when receiving a call, and depending on the type, sends hooking signal No. 1 to the outside line at the time of transfer to directly transfer the call, or temporarily puts the outside line on hold. By capturing a free outside line and then transferring through this free line, there is an effect that transfer can be made between different lines with the same operation on the key telephone.
