Abstract

PURPOSE:To confirm the talking time or the like of a talker with a key telephone system other than that used by the talker by providing a confirmation switch for a talking time and a talking time measuring section to the key telephone system. CONSTITUTION:Upon the arrival to the trunk line talking state, a control section 11 transfers its control to a trunk line speech section 14 and a time measuring section 14 is activated to start measurement of the talking time. While the speech section 14 is in operation, when the user of other key telephone system turns on a confirmation switch 17, a terminal number of the key telephone system in busy with the trunk line and its speech time are displayed. Since the user other than the talker in busy with the trunk line recognizes the terminal number and the talking time of the key telephone system in busy with the trunk line in this way on a display section of the other telephone set than the busy telephone set, the telephone set is efficiently utilized.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is capable of displaying detailed information of a central office line connected to a key telephone set that is being used by another person on the display of the other telephone set by operating the other key telephone set. The present invention relates to a button telephone device that enables

BACKGROUND OF THE INVENTION Conventionally, a key telephone in this type of key telephone device is equipped with a status display unit that displays the status of a central office line.1. The status display section is configured to display whether or not the key telephone is using a central office line. Detailed information such as call time, destination dial, etc. is displayed only on the status display section of the key telephone when the central office line is in use. This is to allow callers to use the telephone more efficiently by avoiding erroneous dialing operations and self-managing call times, etc.

In this way, even with the above-mentioned conventional key telephone device, the call time, etc. can be checked on the display.

Problems to be Solved by the Invention However, in the above-mentioned conventional button telephone device, the caller who is using the central office line is generally concentrating on the content of the call, and therefore overlooks the display of the call time on the status display section. However, there is a problem in that the status display cannot be used effectively.

Furthermore, even if caller managers try to point out so-called long phone calls, they are unable to do so because they do not know the specific length of the call, resulting in the problem of not being able to use the phone efficiently. there were.

The present invention is intended to solve such conventional problems, and allows a user of a key telephone other than the caller to record the talk time, etc. of the caller's key telephone using a key telephone other than the one used by the caller. It is an object of the present invention to provide an excellent key telephone device that can be confirmed.

Means for Solving the Problems In order to achieve the above object, the present invention provides a button telephone set constituting a button telephone device with a confirmation switch for call time, etc. and a call time measurement section, and after operating the confirmation switch,
By specifying the central office line that you wish to check, detailed information such as call time on that central office line is displayed on the display.

Therefore, according to the present invention, when a person other than the caller operates the confirmation switch, at least the call time and the duration of the call for the office line in use are determined under the action of the call time measuring section and the display. FIG. 1 shows the structure of an embodiment of the present invention. In FIG. 1, reference numeral 10 indicates a central office line selection key, for example, a key switch that lights up when talking on a central office line is used, and the person making the call selects an empty central office line after confirming that the key switch does not emit light. Reference numeral 13 denotes a central office line transmitting section which sends a selection signal for making a call to the selected central office line to the central office line communication section I4 and the outgoing dial storage section 12.

The outgoing dial storage section 12 stores the outgoing dial associated with the selection signal. The office line communication unit 14 controls office line communication and extension communication via a main device (not shown).

Reference numeral 15 denotes a central office line incoming call response unit, which responds to incoming calls from the central office line. Reference numeral 17 denotes a confirmation switch, which is turned on when checking the state of the station line. Reference numeral 16 denotes a time measuring section, which measures the telephone call time on the central office line. 18
1 is a display section which, in this embodiment, displays the call time and the terminal number of the key telephone associated with the call time.

Reference numeral 11 denotes a control section, which, as understood from the figure, is connected to the above-mentioned components and to a main device (not shown) that controls them.

Note that FIG. 1 shows a button telephone which is one terminal in the button telephone apparatus according to this embodiment, and this button telephone apparatus has a plurality of similar button telephones.

Next, the operation of the above embodiment will be explained. In the embodiment described above, the central office line transmitting section 13 causes the outgoing dial storage section 12 to store the selection signal selected by the user using the central office line selection key 10 and sent to the central office line. Further, the control unit 11
When the local line communication state is established, control is transferred to the local line communication section 14. On the other hand, when a call is received on the local line, the local line call reception response unit 15 operates, and when the local line communication state is established, the control unit 11 similarly transfers control to the local line communication unit I4.

When the control is transferred to the local line communication section I4, the time measuring section 16 operates and starts measuring the communication time for the local line communication.

For example, when the user of another key telephone sets the confirmation switch 17 to the ON state while the central office line communication section 14 is in operation,
The control section 11 of this other button telephone sets the display section 18 of this other key telephone set to display the information and time stored in the outgoing dial storage section 12 of the key telephone during the central line call, as shown in FIG. Data corresponding to the time measurement information of the measurement unit 16, that is, the terminal number of the key telephone during a telephone call (
15 in the illustrated example) and the call time (1 minute and 20 seconds in the illustrated example).

In this way, according to the above embodiment, a person other than the party on the central line call can display the terminal number of the key telephone on the display of a key telephone that is different from the key telephone in use by the party on the telephone. You can know the call time.

In addition to the above-mentioned terminal number and call time, the display section 18 may display detailed information regarding the office line in use, such as the destination dial stored in the outgoing dial storage section 12.

Effects of the Invention As is clear from the above embodiments, the present invention is capable of displaying at least the terminal number of the caller's pushbutton telephone and the duration of the call on the display section of a pushbutton telephone other than that used by the caller. have an effect.

By introducing the button telephone device according to the present invention, for example, the manager of the caller can point out to the user of the button telephone that it is a so-called long-distance call based on specific numbers. This also has the advantage of allowing relatively efficient use of the telephone.
