Abstract

PURPOSE:To improve use efficiency by responding to an incoming call with facsimile function at the time of detecting the incoming call from an ISDN (integrated services digital network) line during the communication of the telephone function and recording voice information from the other party at the time when response results cannot be communicated. CONSTITUTION:A communication terminal equipment connected to ISDN is provided with an MPU 1 which controls the operation of the whole of the equipment, a ROM 2 where various programs are stored, a RAM 3 where data and pictures are stored, a disk device 4 as a non-volatile memory, a scanner 5 which reads picture data, a printer 6 which outputs received pictures, and a communication part 7 which performs switching between the facsimile function and the telephone function to control the communication. When the incoming call from an ISDN line 8 is detected by the communication part 7 during the communication of the telephone function and response results of the facsimile function cannot be communicated, voice information to the incoming call is sent and voice information from the other party is recorded. Thus, the message of the other party is recorded when the call comes from a telephone set during the communication of the telephone function.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication terminal device having telephone and facsimile functions and connected to an integrated services digital network (I5DN).

[Prior Art] ISDN provides different services such as telephone facsimile, teletex, and videotex in one network. In the initial stage of introduction of ISDN, it is thought that it will coexist with the conventional public telephone network (hereinafter referred to as PSTN) as shown in Figure 3, and connections will be made between these networks.
ISDN telephones and facsimiles will be able to communicate with PSTN telephones and facsimiles, respectively.

Conventionally, with ISDN telephone facsimiles, even if a call is received from the facsimile machine on the other 'B channel' while the telephone is being used using one 'B channel', the incoming call will not be accepted. A receiver is included, and two B channels can be used at the same time, allowing facsimile communications to be made while making a telephone call.

[Problems to be Solved by the Invention] However, even if two B channels can be used at the same time as in the above conventional example, when using a telephone using one B channel, For example, if there is an incoming call from a telephone connected to the PSTN on another "B channel", the other "B channel"
There was a drawback that the incoming call was rejected because it was not possible to make a call using the .

The present invention was made to solve the above problems, and
If you receive a call from your phone during a call using the phone function,
It is an object of the present invention to provide a communication terminal device that records messages from the called party.

[Means and operations for solving the problem] In order to achieve the above object, a communication terminal device of the present invention has the following configuration. That is, in a communication terminal device that has a telephone function and a facsimile function and is connected to an ISDN line, there is a detection means for detecting an incoming call from the ISDN line during communication using the telephone function, and a detection means for detecting an incoming call at the detection means. a response means for responding to the incoming call using the facsimile function; a sending means for sending out voice information in response to the incoming call if the response result by the answering means cannot be communicated by the facsimile function; and a sending means for terminating the sending by the sending means. and recording means for recording voice information from the other party.

[Embodiment] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Description of the facsimile device (FIG. 1)> FIG. 1 is a block diagram showing the configuration of the facsimile device in this embodiment.

In the figure, 1 is an MPU that controls the overall operation of the device;
2 is a ROM that stores various programs, 3 is a RAM that stores data and images, 4 is a disk device as a nonvolatile memory, 5 is a scanner that reads image data, 6 is a printer that outputs the received image, and 7 is a facsimile function. 8 is the communication department that controls communications by switching between and telephone functions;
The SDN line, 9 is a telephone section, and 10 is a bus.

Explanation of Processing Procedure (FIG. 2)> Next, the processing procedure at the time of incoming call in this embodiment will be explained below according to the flowchart shown in FIG.

Note that in the flowchart shown in FIG. 2, the telephone section 9
The process starts with a conversation already being made with an external telephone (not shown) using the B channel of the DN line 8.

First, in step S1, when another call arrives via the ISDN line 8, the communication unit 7 detects the call, and the M
An incoming call detection signal is notified to PU1. When this signal is input to the MPU 1, the process proceeds to step S2, and the usage status of the telephone section 9 is manually inputted via the communication section 7. The result of the manual input is determined in step S3, and if the device is not in use, normal incoming call processing is performed in step S8. This incoming call processing is performed, for example, when the incoming call mode of the facsimile machine is set to automatic incoming call mode, the incoming bell of the telephone rings a specified number of times, and if the operator does not answer the call during that time, the facsimile communication procedure is automatically performed. If the manual reception mode is set, the incoming bell of the telephone will continue to ring until the operator answers the call or the other party disconnects the line.

On the other hand, if the telephone section 9 is in use in the judgment process in step S2, the incoming mode of the facsimile machine is checked in the subsequent step S3, and if the manual incoming mode is set, the process goes to step S7. Proceed to reject the call.

However, if the automatic call receiving mode is set, in step S4, the communication unit 7 is instructed to respond using a facsimile communication procedure in order to know whether the other party's device is a facsimile or a telephone. Upon receiving this instruction, the communication section 7 transmits an identification signal according to the facsimile procedure and waits for reception from the other party's device. After that, when the reception result is notified to MPU1, M
In step S5, the PU 1 determines the result from the communication unit 7, and if the other party's device is a facsimile machine, the process proceeds to step S6 and performs communication processing according to the facsimile procedure. On the other hand, in the judgment process of step S5, if the other party's device is not an automatic facsimile sender but a human is making a telephone call, the process advances to step S9 and, for example, the message "I am currently using the telephone. Please wait for a while." Messages such as "Please call me again" are sent out using voice synthesis. Then, in step SIO, the message from the other party is recorded on the disk device 4.

According to this embodiment, when a call is received from another party during a telephone conversation on the ISDN "'B channel", the incoming call can be accepted and the message from the other party can be recorded. can.

[Effects of the Invention] As explained above, according to the present invention, during a call using the telephone function, it is possible to accept incoming calls from other telephones and record messages from the other party, which improves usage efficiency. do.
