Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an ISDN telephone and an ISDN terminal system.
The present invention relates to an ISDN telephone suitable for use when a DN telephone is connected, and an ISDN terminal system including the ISDN telephone.

(Prior Art) The I5I)N (Integrated Digital Service Network) as a digital line network is expected to provide various information and communication services based on various media such as voice, images, and data. Yes, such service integration network is
On the user side, a large number of ISDN terminals can be connected to and used on the subscriber line.

In ISDN, l-to-n wiring (bus wiring) is defined as one of the wiring forms in the basic interface. That is, the (1) interface also allows bus wiring, and the above-mentioned l-to-n wiring allows connection of up to eight terminals. A socket is provided at the connection point with the bus, and communication is possible no matter which socket the connector is inserted into.

ISDN terminals can be broadly divided into telephones, G4
Typical examples include facsimiles, video telephones/conference terminals (video terminals), and ISDN terminals are one of such final terminals.

However, with conventional ISDN telephones connected to the ISDN mentioned above, if multiple telephones are connected on the same bus and the other party does not specify a subaddress, all the telephones will ring at the same time. do. That is,
Conventionally, ISDN telephones connected on the same bus were
All telephones on the bus are configured to respond to incoming calls that do not specify a subaddress.

(The problem that the invention is trying to solve) However,
In the above-mentioned conventional example, since all the mms on the bus respond, even telephones that do not want to ring are notified of an incoming call, which poses the following problems in terms of usability.

In other words, if a call is received and the caller does not directly specify the caller's own phone, the caller's intended party is different from the operator who received the 711 call. If it is the other party on the call, there is the inconvenience of having to relay the call to the other party.

On the other hand, even though the call is not a general call without specifying a sub-address as described above, but a call is made to a specific terminal with a sub-address specified, that is, even though the call is made by selecting the own phone, Therefore, if the receiver is slow to pick up the phone, the caller may be forced to wait unnecessarily, and it may cause inconvenience and disadvantages such as missing truly necessary communications. be.

An object of the present invention is to provide an ISDN telephone that does not accept incoming calls unless it directly designates itself, and the present invention also provides an ISDN terminal system that uses the ISDN telephone. .

(Means and effects for solving the problem) In order to achieve the above object, the present invention provides an ISDN telephone connected to an ISDN as an ISDN terminal, which has a means for not notifying an incoming call without a subaddress. By doing so, the person using the ISDN telephone can be freed from the above-mentioned troubles.

The present invention also provides an ISDN terminal system in which a plurality of ISDN terminals are connected to an ISDN m-terminal system system bus, the system having a first ISDN telephone equipped with means for not notifying an incoming call without a subaddress; By having at least one second ISDN telephone that can answer even incoming calls without a subaddress, if there are multiple ISDN telephones, a specific ISDN telephone among them, i.e., an incoming call without a subaddress, can be answered. This system allows a second ISDNm operator who can also answer calls to efficiently and appropriately manage incoming calls in the system.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an ISDN telephone according to an embodiment of the present invention.

In the figure, reference numeral 10 indicates the main body of the ISDN telephone (hereinafter also simply referred to as a terminal), which is composed of a digital telephone. The terminal 10 includes a main control section 100, which includes a CPU 10I, a ROM 102 and a ROM1 that store programs for controlling the terminal device.
RAM 10 for executing programs stored in 02
The main control unit lOO controls the entire terminal device by ROMI.
CPU 101 based on the program stored in O2
Controlled by

Above CPU101%ROM l02 and RAM103
The main control unit 100 includes a telephone function unit 11 having an ISDN telephone function, and a line control unit (C
CU) 12, and the line jν control unit 12 is connected to the ISDN bus line A150. The telephone function section 11 is configured to include a handset, a key device including a numeric keypad, a ringing circuit for producing a ringing tone, and the like.

Communication is carried out by the line control unit 1 under the control of the main control unit 100.
2. This is done through the telephone function section II.

That is, when making a call from your own telephone, a voice information signal containing a voice signal converted by the handset circuit in the telephone function section 11 is sent to the line 50 through the line control section 12 connected to the line 50, and At the time of reception, a communication information signal from the other party's terminal side, that is, the calling side, is given to the telephone function section 11 via the line control section 12 via the ISDN network.

Wooden ISDN telephones are equipped with a function that does not notify incoming calls that do not have a subaddress.

Therefore, the main control unit 100 determines whether or not there is a sub-address in the ROM 102, which is a program storage unit, for example, as shown in the flowchart of FIG. A control program is stored in advance to prevent the CP
The Ul0I is configured to execute incoming call processing in accordance with the above control program based on information about the subaddress and other information.

The operation of the terminal upon receiving a call will be described below in accordance with the flowchart of FIG. 2 showing an example of the operation of the wooden terminal 10.

Now, if there is an incoming call from the other party's sending side through the ISDN network and via the line 50, the main control unit lOO, which has been notified of the incoming call, starts the following process.

That is, first, when there is an incoming call, it is analyzed in step 201 whether or not the incoming call information includes a subaddress.

Next, step 20 of determining whether there is a subaddress
Step 2 proceeds to step 202, and branches to operations when the sub-address is included and when it is not included, and if the answer to step 202 is Yes, further checks whether the addresses match or do not match (step 203). ), step 20
4 or step 205 is determined.

That is, if the above-mentioned incoming call information includes a subaddress and matches the own terminal (if the answers to both step 202 and step 203 are Yes), step 20
Proceed to step 4 and accept the incoming call.

In this way, it is possible to accept an incoming call when the user directly specifies the user's own phone, and to appropriately respond to the call when the user's own phone is selected and called. In other words, when a ring tone sounds on an ISDN A8 device that has the incoming call rejection function described later, the user can always recognize that the call is directly specifying the caller, and can quickly answer the call.

On the other hand, if the answer to step 202 is No and there is no subaddress, or if the answer to step 203 is No and the subaddress does not match the own terminal, the incoming call is rejected in step 205.

This prevents calls from being notified to phones that you do not want to ring, unlike in the past, and does not accept calls unless you specify the phone directly. There is no need for the person to have to go through the trouble of relaying the call to the intended party.

FIG. 3 is a diagram for explaining an operation method when an ISDN telephone having the above configuration according to the present invention and a conventional ISDN terminal are connected on the same bus, and shows an example of the configuration of the ISDN terminal system. ing.

In the ISDN terminal system, as shown in FIG. 3, a plurality of ISDN terminals are connected to a DSU (network termination unit) 60, which is a network termination connected to the ISDN network, via a bus line. As mentioned above, as an SDN terminal on the bus, a user with one subscriber line can connect up to 8 terminals, and in this example, a normal ISDN telephone (A)
20. ISD configured as explained in Fig. 1 and Fig. 2
N telephone (B), (C) to-1, 10-2, and I of the pond
An SDN terminal 30 is connected. Other ISDN terminal 3
0 is a facsimile (FAX) in this case.

This system provides an ISDN telephone that does not notify incoming calls without a subaddress, and connects an ISDN telephone that notifies incoming calls without a subaddress on the same bus. This system is designed to manage incoming calls.

That is, in FIG. 3, the former telephones are ISDN telephones (B) and (C) 10-1.10-2, and the latter telephone is ISDN telephone (A) 20.

The operating method will be explained below with reference to FIG.

Suppose that there is an incoming call from an outside line to the address of DSU60. The caller of the other user's phone calls the ISDN phone (B), (C) 10-1,10 with the subaddress.
If -2 is not directly specified, these do not accept incoming calls as described above.

On the other hand, the ISDN telephone (A) 20 also responds to an incoming call without a subaddress. That is, when there is an incoming call without a telephone subaddress, the normal ISDN terminal 1g (A) 20, which accepts incoming calls even without a subaddress, rings. In this way, ISDN phone (A)
20 will ring, so the operator of telephone (A) 20 picks up the telephone and, if necessary, calls ISDN telephone (B) to-1 or ISDN telephone (
C) Transfer to 10-2. At this time, the call information includes ISDN phone (B) 10-1 or ISDN phone (C
) 10-2.

The operator of telephone (A) 20 calls ISDN telephone (B) 1
If the operator of telephone (A) 20 determines that there is no need to transfer the communication to ISDN telephone (C) 10-1 or ISDN telephone (C) 10-2, the operator of telephone (A) 20 terminates the communication.

As described above, by connecting and operating an ISDN phone that rejects incoming calls without a subaddress and a normal ISDN phone (which does not reject incoming calls even if there is no subaddress) on the same bus, you can , that is, in this example, IS
One ISDN phone (A) set in the DN terminal system
20 operators will manage incoming calls, allowing other phones to ignore or reject unnecessary incoming calls.

Note that the present invention is not limited to the above-mentioned embodiments, and includes, for example,
Regarding the ISDN terminal call itself, the operation when there is no subaddress in the flowchart of FIG. 2 is not to reject the incoming call, but to not make the telephone ring.

Further, a selection function may be added that allows switching between a state in which incoming calls without a subaddress are not notified and a state in which it is possible to respond to incoming calls without a subaddress.

In the case of such an ISDN telephone, if one switched to the latter state is used as the ISDN telephone (A) 20 in FIG.
The ISDN terminal system described above can be similarly configured.

(Effects of the Invention) According to the present invention, the ISDN telephone connected to the ISDN as an ISDN terminal has a means of not notifying an incoming call without a subaddress, so that the user does not want to hear a ringing tone. This eliminates the need to notify the telephone of an incoming call, and has the effect that, for example, the person using the ISDN telephone can be freed from the troubles that conventionally existed.

Further, according to the ISDN terminal system of the present invention, there is provided an ISDN terminal system in which a plurality of ISDN terminals are connected on the same bus. , and at least one second ISDN telephone that can respond to incoming calls without a subaddress. operators manage incoming calls,
Ike no i! for unnecessary incoming calls! The call can be ignored or rejected, allowing the system to manage incoming calls efficiently and appropriately.
