Abstract

PURPOSE:To identify a telephone number set to itself in an ISDN telephone set. CONSTITUTION:When a telephone number such as an address or a sub address is set to the ISDN telephone set through the operation of an operation section 5, a control section 1 detects the setting operation to control a display section 4 to always display the set address and sub address onto an address information display section 40 and a sub address information display section 41 in the display section 4. Moreover, when the operator of the telephone set tentatively visits to other location and a call comes to its own equipment, a transfer destination address when the call is transferred to a telephone set at a visit location is set freely and in this case, the transfer address information is displayed on the display section 4. As a result, the operator identifies the set telephone number at a glance.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ISDN telephone device connected to an ISDN network in the form of a bus and for setting telephone numbers such as addresses and subaddresses.

0002

[Prior Art] As is well known, in the ISDN network called INS Net 64, which has already started service, eight terminals can be connected to one metallic line, which corresponds to a conventional analog telephone line. It becomes. In other words, two B channels that enable communication of voice signals and data signals can be secured for one metallic line,
Furthermore, since eight terminals can be connected to this line via the DSU via a bus, a configuration equivalent to 208 conventional key telephone devices is possible. And each terminal is
By executing a predetermined protocol via the D channel, call origination, call reception processing, etc. are performed, and calls and communications are performed with the other party. Note that each of these multiple terminals can be set with its own telephone number, such as an address and subaddress, so that when a call is received from the network, the call can be received only to a specific terminal.

0003

[Problem to be solved by the invention] The above-mentioned conventional ISD
N telephone devices can set telephone numbers such as own address and own sub-address on the device itself, but since these cannot be displayed, especially when such address information is set by a third party, the operator cannot It is difficult to know what kind of telephone number is set on the own device, leading to problems such as confusion in handling.

0004

[Means for Solving the Problems] In order to solve such problems, the ISDN telephone device of the present invention includes a detection means for detecting the setting of address information for the ISDN telephone device, and a detection means based on the detection output of this detection means. and display control means for displaying the address information on the display section.

[0005]

[Operation] When address information is set for the ISDN telephone device, this set address information is displayed on the display section.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of an ISDN telephone device according to the present invention. In the same figure, 1 is this IS
A control unit that controls the DN telephone device, 2 a line interface unit (line I/F unit) that executes protocol processing such as layers 1 to 3 for the ISDN network, 3 a codec circuit, a communication circuit, a tone generation circuit, An analog signal control section consisting of a handset, a speaker, etc., 4 a display section, 5
1 is an operation unit consisting of various operation keys such as dial keys, 6 is an ISDN line, 7 is a line termination unit (DSU) that terminates the ISDN line 6, 8 is an AC adapter, and 9 is an A
C power supply; 10 is a power supply switching unit; and 11 is a power supply unit that supplies power to each part of the telephone device. In addition, DSU7 and AC
Between the adapter 8 and the ISD configured as above,
Up to eight N telephone devices can be connected in multiple ways in a bus format.

[0007] When an incoming call arrives from the ISDN network via the ISDN line 6, protocol processing regarding the incoming call is executed between the line I/F section 2 and the ISDN network via the DSU 7 and the AC adapter 8. This result is notified to the control unit 1. The control section 1 receives this and displays an incoming call on the display section 4, and also controls the tone generation circuit in the analog signal control section 3 to emit a ring tone from the speaker. Then, when the handset in the analog signal control section 3 is picked up, this information is transferred to the line I/F section 2.
The received call response is transmitted to the line I/F unit 2 and the network, and protocol processing related to the incoming call response is executed, and a response call is made.

[0008] When making a call from an ISDN telephone device, the handset in the analog signal control unit 3 is raised,
When the other party's number is operated using the dial keys in the operation unit 5, this information is transmitted to the line I/F unit 2, and protocol processing related to calling is executed between the line I/F unit 2 and the network. be done. As a result, the other party's telephone device is called, and in response to the other party's response, a call is made.

[0009] In such ISDN telephone equipment, address information such as a sub-address indicating an address and an extension number can be set in the equipment itself, and such ISDN telephone equipment is connected to the ISDN line 6 in a bus format. When an incoming call arrives on the ISDN line 6 when multiple connections are made, subaddress information in this incoming call information is received, and a match between the received subaddress information and the subaddress preset in the device is detected. ISDN where the received subaddress matches the preset subaddress.
Only the telephone device is designed to ring for incoming calls. When the operation section 5 is operated in a predetermined manner in order to set address information and sub-address information as described above in the ISDN telephone device, the control section 1 detects this setting operation and stores the information in the memory within the control section 1. In addition to storing the operated address information and sub-address information, the display section 4 is controlled to display the address information on the address information display section 40 as shown in FIG.
Furthermore, the subaddress information display section 41 is configured to display subaddress information at all times. In addition, when the operator of this telephone device temporarily goes to another location and an incoming call arrives at the device, the forwarding address information can be freely set if the call is transferred to the telephone device at the destination. In this case as well, the setting operation on the operation section 5 is detected and the transfer address information is displayed on the display section 4.

[0010] As described above, when address information, subaddress information, and forwarding address information are set in the ISDN telephone device, these are displayed on the display section 4, so that
The operator can clearly identify the telephone number set on his/her own device at a glance.

[0011]

[Effects of the Invention] As explained above, the present invention provides an ISD
N When address information is set for a telephone device, this set address information is displayed on the display, so even if address information is set for this telephone device by a third party, this address information will not be displayed. This has the effect of preventing confusion during handling.
