DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the ISDN telephone apparatus according to the present invention. In the figure, 1 is this IS
A control unit for controlling the DN telephone device and having a clock circuit inside, a line interface unit (line I / F unit) for executing protocol processing such as layers 1 to 3 for the ISDN network, and 3 for a codec circuit , An analog signal control unit including a call circuit, a tone generating circuit, a handset and a speaker, 4 is a display unit, 5 is an operation unit including various operation keys such as dial keys, 6 is an ISDN line, 7 is a line termination device (DS) for terminating the ISDN line 6.
U), 8 are AC adapters, 9 is an AC power supply, 10 is a power supply switching unit, and 11 is a power supply unit that supplies power to each unit of the telephone device. It should be noted that D that inputs one ISDN line 6
On the output side of SU7 , the line I / O configured as above is
Up to 8 ISDN telephone devices including F section 2 can be connected in parallel
Connection is possible due to the bus type as.

When an incoming call arrives from the ISDN via the ISDN line 6, the line I / F via the DSU 7
The unit 2 executes a protocol process regarding an incoming call with the ISDN network, and notifies the control unit 1 of the result. The control unit 1 receives this, displays a message indicating the incoming call on the display unit 4, controls the tone generation circuit in the analog signal control unit 3, and sounds a ring tone from the speaker. Then, when the handset in the analog signal control unit 3 is picked up, this information is transmitted to the line I / F unit 2, and protocol processing relating to an incoming call response is executed between the line I / F unit 2 and the network. A response call is made.

When a call is made from an ISDN telephone device, the handset in the analog signal control unit 3 is picked up.
When the other party's number is operated by a dial key in the operation unit 5, the information is transmitted to the line I / F unit 2, and a protocol process for calling is executed between the line I / F unit 2 and the network. Is done. As a result, the telephone device of the other party is called, and the call by the calling is performed according to the response of the other party.

Next, FIG. 2 is a flow chart for explaining the operation of the control unit 1 of the ISDN telephone device which sets / cancels the service function provided from the ISDN network. This I
A predetermined key in the operation unit 5 in the SDN telephone device is operated,
When a set time registration operation for setting the "phone call" function provided from the network is performed, this is detected, and in step 50, the set time is registered in the memory in the control unit 1. Subsequently, when a release time registration operation for releasing the "phone call" function is performed, this release time is registered in the memory in step 51.

On the other hand, the control unit 1 is provided with a clock circuit, and the control unit 1 compares the output of the clock circuit with the set time and the release time registered in the memory at any time. doing. Then, in step 52, it is judged whether or not the set time is reached, and the set time is reached and "Y" is reached.
If it is determined to be "FA" (Feature) indicating the setting of the "phone call" function for the ISDN network in step 53.
FI (Fea) which is transmitted from the network in correspondence with this FA code while transmitting the Activation information.
true indication) information is received. That is, in this case, if the service function corresponding to this FA information has already been set, the network sets this service function to none, and if the service function has not been set, sets the service function to yes. The FI information is returned to the accessed ISDN telephone device. Then, in step 54, it is judged whether or not the received FI information is the "denwaban" setting information, and if it is the "denwaban" setting information, it means that the "denwaban" function can be set, and the processing ends. , If the received FI information is not set to “Call me”, and it is determined to be “N” at Step 54, the FA information indicating the setting of the “Call me” function is sent to the network again at Step 55. And finish. As a result, in the ISDN network, it is recognized that the "phone call" function has been set for this telephone device. Then, when an incoming call arrives at this ISDN telephone device, the ISDN network has a "phone call" function set in this device, so that the voice message circuit provided in the network is driven to make a call. A predetermined message indicating that the called party is absent is sent to the caller.

If it is judged as "N" in step 52 without reaching the set time, then it is judged in step 60 whether or not the release time has come. If it is judged that the release time has not come, Returning to step 52, if the release time is reached and it is determined to be "Y" in step 60, FA information indicating the setting of the "phone call" function is transmitted to the ISDN network in step 61, and this FA code is sent. The FI information returned from the network in response to is received. Then, in step 62, the received FI information is "phone number".
It is judged whether or not it is the setting information, and if it is not the "Denwaban" setting information, it ends because the "Denwaban" function has been canceled, but the received FI information becomes the "Denwaban" setting. If it is determined to be "Y" in step 62, "denwaban" is again sent to the network in step 63.
The FA information indicating the setting of the function is transmitted and the process ends. As a result, the setting of the "phone call" function for this telephone device is canceled.

As described above, by pre-registering the set time / release time of the service function provided from the ISDN network, the set / release of the function is automatically performed.

[0013]

As described above, according to the present invention, the service function setting information is transmitted to the ISDN network at the registered set time, and the release information is transmitted at the registered release time. Therefore, the service function provided from the ISDN network can be automatically set / released.
