Abstract

PURPOSE:To realize the usage of a facsimile equipment as a telephone set even at the of facsimile communication procedure by generating a warning when a facsimile response is not received within a prescribed time after automatic incoming call so that the facsimile side can be switched to a telephone set. CONSTITUTION:When a ringer from the transmission side is detected, the reception side can be switched to facsimile produre. An initial identification(ID) signal resending repeating time T1 and an initial ID signal resending interval TB are set up to corresponding timers, and when a facsimile response to a 2nd initial ID signal or the like is not obtained, the warning is generated. When an operator replays to a telephone set in response to the warning, facsimile communication is interrupted and a telephone circuit connected to the facsimile side is switched to the telephone set side. In such a constitution, the equipment can be used as a telephone set even at the time of facsimile communication procedure.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention is applicable to general telephone exchanges! ! I! The present invention relates to a facsimile device that utilizes a network and is used as an accessory to a subscriber telephone set in place of a telephone set, and automatically receives a call by automatically entering a facsimile communication procedure when a ringer is detected.

(Prior Art and its Problems) Conventionally, when this type of facsimile device is used as a sending terminal, it can be used both as a facsimile device and as a telephone.

However, when used as a receiving terminal, after detecting the ringer and automatically receiving the call, the line is switched to the facsimile side and the facsimile communication procedure begins, notifying the sending side that it is a non-voice terminal. .

FIG. 3 shows a control flowchart during reception in a conventional facsimile machine.

In the figure, CED represents the called station identification signal, T1 timer represents the time for repeating initial identification signal retransmission, and TB timer represents the initial identification signal retransmission interval.

First, when a ringer is detected, the line is switched to the facsimile side, the T1 timer is set, the CHD and initial identification signals are sent out, and then the TB timer is set. If the facsimile response signal is not received after the initial identification signal is sent until the TB timer times out, the initial identification signal is sent in the same manner until the T1 timer times out. If a facsimile response signal is received during this time, the facsimile communication is continued, but if the facsimile response signal is not received even after the T1 timer times out, it is regarded as an abnormal communication and the line is switched to the telephone side to terminate the facsimile communication.

In this way, with conventional facsimile devices, even if the sender wishes to use it as a telephone, the facsimile communication procedure is unilaterally initiated, so there is no opportunity for a person to respond, and the problem is that it cannot be used as a telephone. There is a point.

(Means for Solving the Problems) In order to solve the above-mentioned problems, a facsimile device provided by the present invention is an accessory device of a subscriber telephone set, which is connected to a telephone line of a general telephone exchange network by switching from the telephone set, and is connected to a telephone line of a general telephone exchange network. A facsimile device that automatically receives a call automatically enters a facsimile communication procedure when it detects a call, and if a facsimile response signal from the sender cannot be received within a predetermined time after the automatic call is received, means for issuing a warning to an operator; and means for interrupting the warning and facsimile communication and switching the telephone line connected to the facsimile side to the telephone side when the operator answers the telephone during the warning; , the facsimile response signal is received or the facsimile response signal is received until a time period in which the facsimile response signal can be accepted has elapsed.

(Example) An example of the present invention will be described below with reference to the drawings.

FIG. 1 is a control flowchart during reception in a facsimile machine according to an embodiment of the present invention.

In the figure, CED represents the called station identification signal, T1 timer represents the time for repeating initial identification signal retransmission, TA timer represents the time until warning starts, and TB timer represents the initial identification signal retransmission interval.

FIG. 2 is a diagram showing an example of a processing sequence during reception in the facsimile apparatus of this embodiment.

This figure shows a case where the TA timer is set to start a warning when a facsimile response signal cannot be detected immediately in response to the second initial identification signal after automatic call reception.

First, when a ringer is detected, the line is switched to the facsimile side, the T1 timer and TA timer are set, the CED and initial identification signals are sent out, and then the TB timer is set. If the sending side is a facsimile machine, the facsimile response signal can usually be detected immediately, so the facsimile communication procedure is entered and facsimile communication is performed as before.

If the sending side's facsimile start timing is delayed or if the sending side is a telephone, the facsimile response signal will not be received at least immediately. Therefore, when the TB timer times out and the initial identification signal is sent again, and a facsimile response signal is not immediately received in response to the initial identification signal, the operator is alerted to this fact.

However, facsimile communication continues even during the warning, and if a facsimile response signal is received during that time, the warning is interrupted and facsimile communication continues.

The alert is interrupted by the operator noticing the alert and going off-hook. At this time, the line switches to the telephone side, and you can talk to the sender. Furthermore, if there is no interruption by the operator during the warning, when the T1 timer times out, the facsimile communication is switched to the telephone side and the facsimile communication is terminated as before.

(Effects of the Invention) As explained above, the present invention provides a warning to the operator when a facsimile response signal cannot be detected within a predetermined period of time after an automatic call is received, so that the operator can communicate from the facsimile side to the telephone side. It can give you an opportunity to switch.

Therefore, even if a facsimile machine that automatically receives a call receives a transmission from a telephone, it is possible to have an operator respond and have a conversation.
