JPH01188158A - Incoming blocking system for facsimile terminal equipment - Google Patents

Abstract

PURPOSE:To block an incoming call in an arbitrary time band such as to refuse reception during a night by providing an incoming blocking registering key and an incoming blocking signal transmitter. CONSTITUTION:In an incoming side facsimile terminal 6, incoming block is registered by an incoming block registering key 7. Next, when there is the incoming call from an outgoing side facsimile terminal 1 through exchanges 2 and 5 to the incoming side facsimile terminal 6, an incoming blocking signal transmistter 8 recognizes that the incoming block is requested by the incoming block registering key 7. An iregal signal, namely, the incoming blocking signal is sent to a preceding station (the exchange 5) and the exchanges 2 and 5 interrupt a line. Then, the incoming call from the outgoing side terminal 1 is canceled. Thus, the incoming call from an outgoing person side can be arbitrarily canceled.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a facsimile terminal that is connected via an exchange and that displays and outputs characters, images, etc. by receiving facsimile information from a calling party. Incoming call blocking system for facsimile terminals that can arbitrarily block incoming calls, especially from callers [Prior Art] Conventionally, no facsimile terminal of this type has an incoming call blocking function. Normally, a facsimile terminal connects an incoming call automatically when an automatic answer is set, and when a manual answer is set, the call is connected in response to a response from the called subscriber.

Furthermore, if the called subscriber does not respond when a manual response is set, the line is disconnected due to a timeout of responsiveness time limit monitoring.

[Problems to be Solved by the Invention] However, in the above-described conventional facsimile terminal receiving mode, incoming calls are always accepted unless there is an abnormality in the facsimile terminal on the receiving side, which prevents the occurrence of mischievous calls. The disadvantage was that it was not possible to control possible nighttime calls.

[Means for Solving the Problems] It is an object of the present invention to solve the above-mentioned problems and to provide a call blocking system for a facsimile terminal that can arbitrarily cancel an incoming call from a caller.

In order to achieve the above object, the incoming call blocking method for a facsimile terminal according to the present invention is provided in a facsimile terminal that is connected to an exchange via a line and that displays and outputs visible information by receiving facsimile information from a caller.
An incoming call blocking registration key that sets the blocking or unblocking setting for incoming calls from the caller side, and when there is an incoming call from the caller side and the incoming call blocking registration key is set to block incoming calls, the above-mentioned The system is equipped with an incoming call blocking signal sending device that sends an incoming call blocking signal to the exchange indicating that connection of an incoming call is rejected.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a call blocking system for a facsimile terminal according to an embodiment of the present invention.

In the figure, the incoming call blocking method for the facsimile terminal according to the present embodiment includes a facsimile terminal 1 on the originating side, an exchange 2 connecting the facsimile terminal 1 on the originating side via rotation, an exchange 5 connected to the exchange 2, and an exchange 5 and a receiving side facsimile 6 connected to the receiving side facsimile 6.

The exchange 2 and the exchange 3 have changeover switches 3a and 4a, respectively.
Equipped with 4 outgoing trunks for 31 people, and 2 switchboards.
The outgoing trunk 3 of the switch 5 and the incoming trunk of the exchange 5 are connected via a line.

The receiving facsimile terminal 6 receives an incoming call based on the setting state of the incoming call blocking registration key 7 and the incoming call blocking registration key 7 for registering the settings for closing or unblocking the incoming call from the calling facsimile terminal 1. The incoming call blocking signal sending device 8 is provided to send out a blocking signal.

Next, the operation of this embodiment will be explained.

First, in the facsimile terminal 6 on the receiving side, incoming call blocking is registered using the incoming call blocking registration key 7.

Next, when a call is received from the originating facsimile terminal 1 to the receiving facsimile terminal 6 via the exchange 27.5,
The incoming call blocking signal sending device 8 recognizes that incoming call blocking is requested by the call blocking record key 7. Then, an illegal signal, that is, an incoming call block signal, is sent to the previous station (exchange 5), causing the exchange 2.5 to disconnect the line, and the incoming call to the originating facsimile terminal 1 can be canceled.

[Effects of the Invention] As explained above, the present invention provides an incoming call blocking registration key and an incoming call blocking signal sending device, so that it is possible to block incoming calls at any time, such as refusing to accept calls at night. There is an effect that can be done.

Claims (1)

[Scope of Claims] In a facsimile terminal that is connected to an exchange via a line and displays and outputs visible information by receiving facsimile information from the caller, the system is capable of closing or unblocking an incoming call from the caller. an incoming call blocking registration key for setting the incoming call, and an incoming blocking registration key that indicates to the exchange that connection of the incoming call is rejected when the incoming call blocking registration key is set to be blocked when there is an incoming call from the caller side. 1. A call blocking method for a facsimile terminal, characterized by comprising a call blocking signal sending device for sending out a signal.
