The U section 8 will be described later in detail. The external telephone 9 connected to the NCU unit 8 may be a normal telephone simply responding to a call signal from a line, but in the present embodiment, the telephone corresponding to the outgoing telephone number notification service is used. Is assumed to be connected.

Here, a connection procedure of a calling telephone number notification service which is deeply related to a processing procedure in the facsimile apparatus according to the present embodiment, which will be described later, will be described.

First, the connection operation sequence in the calling telephone number notification service shown in FIG. 2 will be described. In the figure, the transmitting terminal corresponds to a partner device that transmits the facsimile apparatus according to the present embodiment as a receiving terminal, and the ID receiving terminal and the receiving terminal are the same terminal and the facsimile apparatus according to the present embodiment. Is equivalent to Further, the subscriber line exchange accommodating the calling terminal and the subscriber exchange accommodating the receiving terminal are shown as one exchange for convenience, but these exchanges may actually be different.

In the connection operation sequence shown in FIG.
The calling terminal goes off-hook (phase F1), closes the DC circuit with the exchange, and dials the telephone number of the called terminal (phase F2).

In response, the exchange inverts the polarity of the subscriber line accommodating the ID receiving terminal corresponding to the telephone number dialed from the calling terminal (phase F3),
An ID receiving terminal activation signal is transmitted (phase F4). It should be noted that the ID receiving terminal activation signal differs from the general calling signal only in cadence, and the other signal characteristics are the same.

When the ID receiving terminal receives the ID receiving terminal activation signal from the exchange, the ID response terminal returns a primary response signal to the exchange by closing the DC loop of the line (phase F5).

Upon receiving the temporary response signal, the exchange sends the originating ID of the calling terminal to the ID receiving terminal as a modem signal, which the ID receiving terminal receives (phase F6).

Here, the data format of the calling ID received by the ID receiving terminal will be described with reference to FIG.

In the figure, the signal of the calling ID is SOH (start) indicating the start of the heading of the information message.
of header), a header indicating information transmission from the exchange to the terminal, an STX (start of text) indicating the start of text and an end of heading, and an SI (shift in) indicating that a graphic character uses Roman characters. Followed by an ETX indicating the end of the text, followed by the body of the message
(End of text) and an error detection code (C

The message body is composed of a service type (calling number notification service), a message length indicating the number of bytes of the message, and parameters.

Further, the parameters include a parameter type,
It consists of a parameter length and information content. As shown in FIG. 4A, the parameter type is divided into two types according to the parameter type value.
If "01", it indicates that the parameter name is the calling telephone number, that is, the information content is the telephone number of the calling terminal to be notified. If the type value is "001001
If "0", the parameter name indicates the reason for non-notification of ID, that is, the information content indicates that the telephone number of the calling terminal is non-notification and the reason for the non-notification.

As shown in FIG. 4 (b), the specific contents of the information contents of the two types of parameters, "calling telephone number" and "ID non-notification reason" are as follows. This is a number expressed within 20 numeric characters, and "ID non-notification reason" is one character indicating the reason for non-notification.

In the case of "ID non-notification reason", the reason for notifying the caller ID, which is indicated by one character, is as follows.
As shown in FIG. 4 (c), the call is classified into "rejection by caller", "outside service area call" of outgoing telephone number notification service, or "public telephone call".

The reason why the ID is not notified is "rejection by the caller" when the dialing is performed by adding "184 (Iyo)" before the telephone number to be dialed to specify the receiving terminal on the transmitting terminal side. It is. Therefore, whether the operator of the transmitting terminal wants to notify or not notify the calling telephone number is transmitted to the ID receiving terminal as information content of the calling ID depending on whether “184” is added or not. can do. Also, the ID receiving terminal:
By being notified from the exchange that "outside service area" or "outgoing public phone" is the reason for non-ID notification,
You can know that.

Now, returning to FIG. 2, upon receiving the calling ID in phase F6, the ID receiving terminal returns a reception completion signal to the exchange by releasing and cutting off the DC loop of the line (phase F7).

Upon receiving the reception completion signal in phase F7, the exchange sends a normal calling signal to the receiving terminal,
The receiving terminal receives (phase F8). Note that the exchange sends a ringback tone to the calling terminal at the same time as sending a calling signal to the called terminal (phase F).

In the above-described embodiment, a facsimile apparatus to which a telephone is connected has been described as an example of the communication terminal apparatus according to the present invention as an external communication terminal apparatus compatible with the calling telephone number notification service. The present invention is not limited to this, and can be applied to other communication terminal devices. Needless to say, the external communication terminal device can be connected to not only a telephone but also other communication terminal devices.

[0121]

According to the first aspect of the present invention, if the destination device identification means cannot detect that the destination device of the incoming call is of the same type as the own device, the calling device corresponding to the calling telephone number notification service. Thus, a series of calling operations are performed on the external communication terminal device connected to the connection means while maintaining the incoming line, according to a predetermined connection procedure based on the calling telephone number notification service, and the calling ID is output.
A calling ID notifying signal including the calling ID stored in the storage means is transmitted, and the communication control means controls the external connection connected to the connection means for a call from the calling telephone number notification service corresponding calling means. When a response from the communication terminal device is detected, the connection unit is switched to the held line, and the connection unit is switched to the held line. Is detected, the communication is directly performed with the partner device. If the partner device is the same type as the own device, the communication can be performed as it is, and the partner device is the same type as the own device. Otherwise, even after an incoming call, the external communication terminal device can be called by the connection procedure based on the calling telephone number notification service and connected to the line that received the call, and the outgoing telephone number of the external communication terminal device can be connected. Effect can be effectively utilized functions corresponding to the notification service is obtained.

According to the second aspect of the present invention, the source ID
If the calling ID received by the receiving means is not registered in the calling ID list registering means, the calling means corresponding to the calling telephone number notification service calls the external telephone connected to the connecting means while holding the incoming line. A series of calling operations are performed on the communication terminal device according to a predetermined connection procedure based on the calling telephone number notification service, and a calling ID notification signal including a calling ID stored in the calling ID storage means is transmitted, and The communication control means, when detecting a response from the external communication terminal device connected to the connection means with respect to the call from the calling telephone number notification service corresponding calling means,
While the connection means is switched and connected to the held line, if the calling ID received by the calling ID receiving means is registered in the calling ID list registering means, the connection is directly performed with the partner device. In order to perform communication, if the partner device is of the same type as the own device registered in the calling ID list registration unit, communication can be performed as it is, and the partner device is not registered in the calling ID list registration unit. If the external communication terminal device is not of the same type as the own device, the external communication terminal device can be called and connected to the line that received the call by a connection procedure based on the calling telephone number notification service even after receiving the call. This makes it possible to effectively use the function corresponding to the outgoing telephone number notification service.

According to the third aspect of the invention, the calling telephone number notification service corresponding calling means receives the incoming call even if the calling ID received by the calling ID receiving means is registered in the calling ID list registering means. If the partner device identification unit cannot detect that the partner device is of the same type as the own device, the external communication terminal device connected to the connection unit is called, so that the registration content in the calling ID list registration unit is incorrect. Even when the external communication terminal device is in use, the external communication terminal device can be called smoothly.

[0124] According to the invention according to claim 4, the communication control means determines whether the called party device that has received the incoming call has a calling ID received by the calling ID receiving means even if the calling ID is not registered in the calling ID list registration means. If the other device identification unit detects that the device is of the same type as the own device, the communication is directly performed with the other device, even if the registration content in the calling ID list registration unit is incorrect, The original communication of the own device can be performed smoothly.

According to the fifth aspect of the present invention, according to a communication result indicating whether the called device that has received a call has communicated with itself or has communicated with the external communication terminal device,
The source ID receiving unit receives the source ID of the partner device received by the source ID list registering unit, or the source ID list registering unit deletes the source ID automatic registering unit. Judgment and received I
