Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is used for a key telephone device. In particular, the present invention relates to a key telephone device connected to a PBX exchange having transfer means.

〔Overview〕

According to the present invention, the transfer means of the key telephone device sends a transfer notification to a LAN line connecting the key telephone devices, and displays the identification name of the transfer source on the display of the transfer destination based on the notification, thereby reducing the size. In the case of a large scale, a main control device which is expensive can be omitted.

[Conventional technology]

The conventional example is constituted by a main control device and a plurality of telephone terminal devices. As shown in FIG. 3, a plurality of PBX exchange lines 19 and a plurality of telephone terminals 18 are connected to the main control device 17,
When transferring a call from an extension telephone, the operator operates a key of the telephone terminal 18 and the main controller 17 transfers the telephone to another telephone terminal.

[Problems to be solved by the invention]

In such a conventional example, a main control device and a telephone terminal device are required, and there is a disadvantage that the cost increases when the number of telephone terminal devices is small.

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate such disadvantages and to provide a private telephone apparatus which can be applied to a system having a small number of telephone terminal apparatuses and can reduce the equipment cost.

[Means for solving the problem]

According to the present invention, there is provided transfer means for accommodating a plurality of telephone terminals and transmitting a call signal to a telephone terminal having the transfer destination telephone number in accordance with a transfer instruction signal and a transfer destination telephone number coming from the telephone terminal. In a private branch exchange provided in a private branch exchange, each telephone terminal is connected to each other by an independent transmission path different from a telephone line passing through the private branch exchange, and each telephone terminal is connected to a telephone housed in the private branch exchange. Display means for displaying a list of identification names including the telephone number of the terminal, and operation means provided corresponding to the identification names of the telephone terminals listed on the display means, wherein the telephone related to the operated operation means A touch panel for determining a terminal as a transfer destination of a call signal arriving from the private branch exchange; and an interface for notifying a transfer notification from the transfer source telephone terminal to the transfer destination telephone terminal via the independent transmission path. Source circuit terminal among the identification names of the telephone terminals listed on the display means of the transfer destination telephone terminal in response to the transfer notification notified from the transfer source telephone terminal. And control means for displaying the distinguished name of the subject distinguished from other distinguished names.

[Action]

When transfer between telephone terminals is required, the transfer control means in the telephone terminal issues a transfer request signal to the PBX exchange in accordance with the instruction of the operator, and at the same time notifies the transfer to the transfer destination telephone terminal via the LAN. The telephone terminal that has received the transfer notification displays that the transfer has been performed after the internal transfer control means waits for a call signal from the exchange.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a connection configuration diagram of this embodiment. FIG. 2 is an internal configuration diagram of the telephone terminal of this embodiment.

The telephone terminal of this embodiment has the function of a personal computer, and has a large display unit 6 and a touch panel 7. That is, this embodiment accommodates a plurality of telephone terminals 2, 3,... And attaches the transfer destination telephone number in accordance with the transfer instruction signal and the transfer destination telephone number coming from the telephone terminals 2, 3,. A PBX exchange 1 serving as a private branch exchange, and a transfer means for sending a call signal to the selected telephone terminal.
As means characterized by the present invention, a display unit 6 which is a display means for displaying a list of identification names of telephone terminals accommodated in the private branch exchange, and corresponding to the identification names of telephone terminals listed on the display means. A touch panel 7 having an operating means provided in a predetermined manner, and determining a telephone terminal associated with the operated operating means as a transfer destination of a call signal coming from the private branch exchange;
Circuit means having LAN4 which is an independent transmission path for transferring a transfer notification from the transfer source and the telephone terminal to the transfer destination telephone terminal,
The personal computer means 8 which is a control means for displaying, among the identifiers of the telephone terminals listed on the display means in response to the transfer notification, the identifier of the telephone terminal of the transfer source of the transfer notification as distinguished from other identifiers. And

Next, the operation of this embodiment will be described. First, when a call is made from the PBX exchange 1 to the telephone terminal 2, the operator of the telephone terminal 2 picks up the handset 5 and answers the telephone. If the call is for the telephone terminal 3, the operator of the telephone terminal 2 touches the name of the operator of the telephone terminal 3 in the list of transfer destinations displayed on the display unit 6. A touch panel 7 is mounted in front of the display unit 6, and when the operator touches the touch panel 7, the personal computer unit 8 detects it and instructs the transfer control unit 9 to transfer. The transfer control means 9 sends a transfer instruction signal and a transfer destination telephone number to the PBX exchange 1 through the telephone interface 10. At the same time, a transfer notification is transmitted to the telephone terminal through the LAN interface 11. When the telephone terminal 3 receives the transfer notification, the internal transfer control means 9 waits for a call signal from the PBX exchange 1, and when the call signal is received, displays where the transfer has been made to the display unit 6 through the personal computer means 8. Also,
A ringing tone sounds from the speaker 12.

〔The invention's effect〕

According to the present invention, as described above, since the telephone terminals are connected via the LAN, there is an effect that high functions can be realized with a relatively inexpensive configuration.
