JPH05122308A - Equipment and method for preventing mis-reply by isdn terminal equipment - Google Patents

Abstract

PURPOSE:To provide an ISDN terminal equipment mis-reply prevention device by identifying a call waiting additional service and a usual arrival of a call in an ISDN terminal equipment so as to prevent mis-reply. CONSTITUTION:In the ISDN terminal equipment employing the D channel signal system recommended as the international standards, an additional service controller 4 identifies a call waiting additional and a usual call based on an incoming call inputted from a subscriber line 1 via a subscriber interface controller 2, and when the call waiting call is identified, the arrival of the call waiting call is displayed on a display device 7 via a man-machine controller 5 to prevent the user from replying by mistake.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an erroneous response prevention system for a call waiting supplementary service (call waiting system) in an ISDN terminal.

[0002]

2. Description of the Related Art Conventionally, since an ISDN terminal does not have a display capable of displaying a call waiting supplementary service, it is impossible to distinguish between a normal call and a call waiting call.

[0003]

DISCLOSURE OF THE INVENTION The conventional ISD described above
Since the N terminal does not have an indicator capable of displaying that the terminal is a call waiting supplementary service, it is not possible to distinguish between a call waiting request and a normal incoming call. There was a drawback that it answered incorrectly as an incoming call but was not connected.

[0004]

An erroneous response prevention device for an ISDN terminal, which is the first solution of the present invention for solving the above problems, is connected to a subscriber line transmitting a D channel signal recommended as an international standard. A subscriber interface control device, a terminal control device for controlling basic services of the ISDN terminal, a bell for notifying an incoming call, a display device for displaying a call waiting supplementary service, and inputting / outputting voice information with a user. From a subscriber line through a telephone device, an input device for key input, a man-machine control device for controlling signal exchange between the bell, the display device, the telephone device and the input device, and the subscriber interface control device. It identifies whether the incoming call entered is a call waiting supplementary service or a normal call. And a supplementary service control device for controlling the display device so that the display device displays an identification display as a call waiting supplementary service and informs the user that the call is a normal call. And

A method for preventing an erroneous response of an ISDN terminal which is a second solution of the present invention for solving the above problems is a subscriber interface control connected to a subscriber line transmitting a D channel signal recommended as an international standard. Equipment and ISDN
A terminal control device for controlling basic services of the terminal, a bell for notifying an incoming call, a display device for displaying a call waiting supplementary service, a communication device for inputting / outputting voice information with a user, and an input for key input In a method of preventing an incorrect response of an ISDN terminal, which comprises a device, a man-machine control device for controlling signal transmission / reception of the bell, display device, communication device and input device, and a supplementary service control device for controlling call waiting supplementary service Identifying whether an incoming call input from the subscriber line via the subscriber interface controller is a call waiting supplementary service or a normal call, and if it is a call waiting supplementary service, the display is displayed via the man-machine controller. A call waiting supplementary service is displayed on the device to notify the user, If the call is characterized in that the said bell so as to broadcast.

[0006]

When an incoming call is received from a subscriber line using the D channel signaling system recommended as an international standard, the input waiting call is discriminated between a call waiting supplementary service and a normal call by the supplementary service control device, When the call waiting call is identified, the display device displays the call waiting call to prevent the user from answering by mistake.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an ISDN terminal for implementing the call waiting system (call waiting supplementary service) of the present invention.

In FIG. 1, a 2B + D ISDN subscriber line 1 consisting of two B channels and one D channel is
It is connected to a subscriber interface control device 2 that controls the subscriber line 1. The subscriber interface control device 2 is connected to the man-machine control device 5 via a signal line S10.
Connected to a supplementary service control device 4 for controlling supplementary services such as a call waiting supplementary service by a signal line S11, and connected to a terminal control device 3 for controlling a basic service of an ISDN terminal by a signal line S13. .. The supplementary service control device 4 uses the signal line S12 for the man-machine control device 5, and the terminal control device 3 uses the signal line S14.
And are connected to the man-machine control device 5, respectively.
The man-machine control device 5 is connected to a bell 6 capable of producing a plurality of tones by a signal line S15, is connected to a display device 7 such as a display and a lamp by a signal line S16, and is connected to a communication device 8 such as a handset and a signal line S17. It is connected to the input / output device 9 such as a dial and push key and the signal line S18.

The operation of the above arrangement will be described below. Here, FIG. 2 is a flowchart showing the procedure of the call waiting supplementary service of the present invention.
In FIG. 2, when a call is input to the subscriber interface control device 2 via the subscriber line 1, the subscriber interface control device 2 performs an incoming call process (step S
1) It is determined whether the call request is a supplementary service request for call waiting without a channel (step S
3). If it is determined that the service is a call waiting supplementary service, the man-machine control device 5 causes the display device 7 to display that the service is a call waiting supplementary service (step S3). However, if it is determined in step S2 that the service is not a call waiting supplementary service, the bell 6 is rung through the man-machine control unit 5 to notify the arrival of a normal call (step S4). After this, the user picks up the receiver and transitions to an input waiting state as to whether or not to go off-hook (step S5).

[0010]

As described above, the present invention is based on the ISDN.
The terminal is equipped with a display device (display, lamp, bell with different tone color, etc.) that can indicate that it is a call waiting supplementary service, and a supplementary service control device that identifies and displays the call waiting call. Since the device distinguishes between a normal call and a call waiting call and displays on the display device that the call is a call waiting call, it is possible to prevent the user from erroneously answering.
