DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal adapter device, and more particularly to an I / O terminal having a port for an analog telephone.
The present invention relates to a terminal adapter device for SDN.

[0002]

2. Description of the Related Art Conventionally, some terminal adapter devices have a port for an analog telephone. When setting the self-number in the terminal adapter device, the self-number is set using a setting unit such as a key of the setting device.

[0003] In this type of terminal adapter device, the telephone and the terminal adapter to be actually used are sometimes in a remote place, and can be moved to a place where the terminal adapter is installed. As such a terminal adapter device, there is, for example, a device described in JP-A-3-157040 or a terminal adapter described in JP-A-3-126355.

[0004] The device described in Japanese Patent Application Laid-Open No. 3-157040 discloses a method of calling its own terminal device, transmitting stored diagnostic data, and comparing the transmitted data with the received data at the time of reception. Functions inside the device can be diagnosed. The terminal adapter described in JP-A-3-126355 selects an information element of an ISDN network set in advance by a dual tone multi-frequency (DTMF) signal from a terminal device and transmits the information element to the network. A plurality of attributes can be set for one terminal device.

[0005]

However, the conventional terminal adapter device has to be moved to an installation place of the terminal adapter when the telephone and the terminal adapter to be actually used are separated from each other.
It was inconvenient to use.

Further, in the conventional terminal adapter device, when the set number is wrong and the incoming call is rejected by the terminal adapter, there is a problem that the call can be made and the mistake is hardly noticed.

An object of the present invention is to improve operability by directly setting a self-number from a telephone connected to a terminal adapter.

[0008] Another object of the present invention is to provide a terminal adapter device that can promptly confirm whether an incoming call is returned.

[0009]

Means for Solving the Problems As means for solving the above problems, the terminal adapter device of the present invention provides a notification that a predetermined self-number is to be set, and thereafter inputs from an external telephone. The registered dual tone multi-frequency (DTMF) signal can be determined as a self-number for registration. In addition, the present invention has a calling function for making a call to the input self-number when registration of the self-number is completed. If the self-number registered in advance after calling is correct, a call is received to the terminal adapter. Is returned, it is possible to determine whether or not the own number is correct based on the presence or absence of the incoming call.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A terminal adapter device according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG.
FIG. 1 is a block diagram illustrating a configuration of a terminal adapter device according to one embodiment of the present invention.

In FIG. 1, a terminal adapter 1
Is a terminal adapter for ISDN. The terminal adapter 1 includes a calling signal generation circuit 3, a dual tone multi-frequency (DTMF) signal detection circuit 4, a PCM conversion circuit 5, a control unit 6, and an S (space) / T
It comprises an interface unit 7 having a (time) switch.

The terminal adapter 1 converts an analog signal and a digital signal (PCM code signal) between the interface unit 7 and the external telephone 2 mutually. The call signal generation circuit 3 generates a call signal 120 to the external telephone 2. The DTMF signal detection circuit 4 detects a DTMF signal (dual tone multi-frequency signal) input from the external telephone 2. The PCM conversion circuit 5 supplies a current to the analog signal interface and detects a voltage, and outputs a converted output.
The control unit 6 inputs control signals to the call signal generation circuit 3, the DTMF signal detection circuit 4, the PCM conversion circuit 5, and the interface unit 7 to operate them. Also, ISD
The N network 8 is connected to the interface unit 7.

Next, the operation of the terminal adapter according to the embodiment of the present invention will be described with reference to FIG. When setting the own number, a notification to the effect that the user sets a predetermined self number is sent from the external telephone 2 to the terminal adapter 1. Thereafter, the terminal adapter 1 performs the following operation.

First, the user off-hook the external telephone 2 for setting his / her own number. When the terminal adapter 1 detects an off-hook from the external telephone 2 ,
The TMF signal detection circuit 4 starts detecting a dual tone multi-frequency signal. In DTMF signal detection circuit 4, after detecting a valid DTMF signal, the input of the self-number the user has predetermined to notify the completion, the self-number input to the terminal adapter 1, phase
IS using the interface unit 7 as the local telephone number
A call is made to the DN network 8. At this time, information specific to the subaddress is allocated in order to clearly indicate that the call is for setting the own number. Here, the entered self number is
