When an incoming call is given from an opposite telephone set to a remote operation subscriber number, a communication control part 7 controls an automatic response control part 11 and outputs a response message. A sound guidance control part 12 executes sound guidance and the DTMF detection circuit 10 receives an operation request by the DTMF signal from the opposite telephone set. Thus, setting of the various communication attributes of a self-device and operation of the incoming calls by the individual extensions in an analog terminal 5 are executed.

The ISDN terminal adapter 1 is an ISD
A plurality of subscriber numbers on the N network are assigned. One of them is assigned for remote operation.
Connect to 1.

D of the ISDN terminal adapter of the present invention
The TMF detection circuit 10 is different from the analog terminal interface unit 4 in that the conventional DTMF detection circuit exchanges information only with the analog terminal interface unit.
A port (interface) for exchanging information is created on both sides of the SDN line interface unit 6, and a DTMF signal (a push-button dial signal composed of a combination of two frequencies) is detected from the digitized signal.

The ISDN terminal adapter and the ISD
N-terminal adapter accommodated in an ISDN network (not shown) accommodated through an ISDN line or an analog network (not shown) connected to this ISDN network, and capable of transmitting and receiving voice information and transmitting DTMF signals (Not shown) together with the remote control system of the ISDN terminal adapter.

Here, it is assumed that an example of a code system of an access code (DTMF signal) from a partner telephone set is defined as follows.

First, if the first digit of the DTMF signal sent from the telephone is "1", and if the next one digit (the second digit) is "2", the request is an individual call request.
Further, the next one digit (third digit) “1” to “4” is an extension number. That is, the DTMF signal at the time of designation of each extension of the analog terminal 5 (analog terminal interface unit 4) is one of 121, 122, 123, and 124. When five or more terminals are provided, “5” or more can be assigned as an extension number.

DTMF sent from the telephone first
If the first digit of the signal is “9”, the setting value change request is made only when the next two digits (the second and third digits) are “87”. Further, the next one digit (fourth digit) is a port number (1 to 4 are analog ports, and the fifth and subsequent data ports), then two digits (fifth and sixth digits) are a function number, and the subsequent one digit ( (7th digit) is the set value.

Table 1 shows examples of attributes (function numbers and set values) relating to analog ports.

[Table 1]

Next, an operation of the ISDN terminal adapter and a remote control method thereof will be described.

First, an incoming call from the other party's telephone is
An operation for making a designated incoming call to a specific terminal (telephone) among the plurality of analog terminals 5 connected to the DN terminal adapter 1 will be described with reference to the sequence diagram of FIG.

The ISDN terminal adapter 1 sends out a calling message S11 in response to a call setting message S10 for the remote operation subscriber number from the partner telephone. Subsequently, the ISDN terminal adapter 1 causes the automatic response control unit 11 to transmit a response message S12.
Thereafter, the voice guidance control unit 12 prompts the user to perform an operation following the other party's telephone in the voice guidance S13.

An individual incoming call request S14 for connecting to a designated analog terminal 5 among a plurality of analog terminals 5 from a partner telephone (for example, for the analog terminal 5 to which the extension number "3" is assigned, " When the dial data “123” is transmitted on the Bch, the DTMF detection circuit 10 detects the request signal and notifies the communication control unit 7 of the request signal.
The communication control unit 7 sends the designated analog terminal 5 (extension number =
3) sends the incoming ringer S15 to the port to which is connected. When the analog terminal 5 goes off-hook (S16),
A call path is formed. According to these sequences, it is possible to receive a call to the specific analog terminal 5 only by an operation from the partner telephone.

FIG. 3 is a sequence diagram for performing an operation of changing the attribute set value to the ISDN terminal adapter 1 in response to a set value change request from the other party's telephone.
The process from the call setting message S10 to the voice guidance S13 from the partner telephone is the same as in FIG. 2, but one set value can be changed and stored by sending the setting change request S20 from the partner telephone. By repeating the process of the setting value change request S20 from the process of the voice guidance S13,
Several types of set values can be changed continuously.

As described above, the attribute set value change request S20 includes a code (“987”) indicating the change of the set value,
It is composed of a code indicating the port number (for example, “2”), a code indicating the function number (for example, “01”), and a code indicating the setting value (for example, “3”). In this example ("98
72013 ”) indicates that a FAX is connected as the terminal with the port number“ 2 ”(the analog terminal 5 with the extension number“ 2 ”).

[0032]

According to the present invention, a call is transmitted to an ISDN terminal adapter from a telephone connected via an ISDN network or an analog network connected to the ISDN network to a subscriber number assigned for remote operation. And
When receiving the voice guidance prompting the transmission of the operation request from the ISDN terminal adapter that has detected the incoming call to this subscriber number, the terminal transmits an individual call designation request or a communication attribute information setting change request by a DTMF signal, and the DTMF received by the ISDN terminal adapter The ISDN terminal adapter analyzes the signal and, in the case of an individual call designation request, makes the corresponding terminal accommodated in the corresponding device, and in the case of a communication attribute information setting change request, changes the setting value of the corresponding self-stored communication attribute information. Without using keys or DIP switches provided on the terminal, or directly accommodated terminals such as data terminals or analog telephones, and special contracts or sub-addresses that require a fee such as a dial-in contract on the called side. Without using the ISDN-specific service, With less resource configuration by remote control of the machine, it is possible to improve convenience such be easily changed to be or communication attribute information for incoming individually to the terminal, such as the specified analog telephone.
