Abstract

PURPOSE:To make a light emitting element or sounding element illuminate or raise an alarm and to easily grasp a circuit state by providing the light emitting element or sounding element to a modular outlet to which a telephone set is connected. CONSTITUTION:When there is a telephone call through a line wire, a CPU part 12 detects the incoming through a circuit control part 11 and drive the bells or speakers of telephone sets 4 and 5 through the circuit control part 11 to generate an audible ringing tone while drive transistors(TR) 13 and 14. In such a case, the TRs are driven with a signal which enable LEDs 22 and 23 to blink in short cycles. For example, when a line wire telephone call received by the telephone set 4 is transferred to the telephone set 5, a dial number for transfer is dialed and then a holding state is entered. This state is detected by the CPU part 12, which applies a signal with a long on-off period to the TRs 13 and 14. Consequently, even when a general telephone set is used, the circuit state is easily grasped.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a home telephone system in which the usage status of home telephones configured using single-use telephones can be displayed on each telephone side.

[Conventional technology]

Some conventional home telephone systems include, for example, a control device connected to a central office line and a plurality of telephones (for example, five) each connected to the control device.

The control device has a function of designating one of the plurality of connected telephones as a base unit, connecting an outside line to the base unit, and enabling transfer between the plurality of telephones. moreover,
It is possible to make external calls from each telephone and to make internal calls between telephones, and it is also possible to connect a doorphone and use it as an intercom. In addition to NTT-specification telephones, fashion telephones with creative designs and multi-function telephones with an emphasis on functionality are used, but it is necessary to standardize them according to the type of line (dial type, button type). There is.

In the above configuration, when a call is received from outside, if the recipient is not the person requested by the other party and is in a room where another telephone is installed, the number is pre-designated as a hold number. If you operate the dial number (for example, #2) to put it on hold and operate the dial number assigned to the transfer destination phone, the extension will become active and you will not be able to call the transfer destination (the other party on the extension). can. In addition, when using as an extension phone, after confirming that neither phone is in use, you can call the other party's phone by pressing (or turning) the phone number specified in advance on the phone you want to call. can. Furthermore, if the doorbell is connected, by pressing the button on the doorbell,
A chime sounds from the speakers of each phone all at once. This chime is set to a different tone from the ring tone for outside lines and extensions, so it can be easily distinguished.

Furthermore, in addition to being able to call multiple other telephones at the same time from 1flN, it is also possible to restrict outgoing calls by prohibiting external line connections from designated telephones. Furthermore, a speed dial function, redial function, etc. are provided.

In this way, with a home telephone system, telephones can be easily installed in multiple locations by simply connecting a commercially available telephone of the user's choice to a control device, and then replacing the control device with the telephone that was connected to the line. can do.

[Problem that the invention seeks to solve]

However, in conventional home telephone systems, each telephone is a general telephone that is not made for home telephone use, so the line usage status (incoming call, busy call, on hold, etc.)
They were not equipped with a display device, etc., making it difficult to grasp the line usage status, making them less user-friendly than dedicated home telephones.

[Means for solving problems]

The present invention has been made in view of the above, and even when configuring a home telephone using -m telephones, the modular outlet to which each telephone is connected can emit light in order to display or warn the usage status. The present invention provides a home telephone system in which elements or sounding elements are provided and these elements are turned on or give an alarm depending on the usage status of the line.

According to the home telephone system of the present invention, the light emitting element or sounding element of the modular outlet near the installation location of the telephone displays or alarms the line usage status ascertained by the control device, making it easy to grasp the line status. It is something.

〔Example〕

Hereinafter, the home telephone system according to the present invention will be described in detail for the case where there are two telephones.

FIG. 1 shows an embodiment of the present invention, in which a control device 1 connected to a line, modular outlets 2 and 3 installed on a wall or the like near a place where a telephone is to be installed, and the outlets 2 and 3 Telephones 4 and 5 (
(commonly commercially available), indoor wiring 6 and 7 that connect the control device 1 and the outlets 2 and 3, and a control device that sends signals to control the lighting of the light emitting elements to each of the modular outlets 2 and 3. It is composed of signal lines 8 and 9 supplied from l.

The control device 1 includes a line control unit 11 that controls telephone calls between the central office line and the telephone 4 or 5, or between the telephones 4 and 5, and a CPU that controls the line control unit 11 in accordance with each of the above-mentioned functions.
12, and transistors 13 and 14 that perform a switching operation based on a signal whose level changes depending on the state of use of the line.

In addition, the modular outlets 1-2 and 3 have a modular jack 21 on the front of the case 23, as shown in FIG.
is provided, and an LED 22 as a light emitting element is provided adjacent to the modular jack 21. Figure 2 shows the exposed type, but there are also two types that are embedded in the wall.

In the above configuration, when there is a call from an outside line, the 020 unit 12 detects the incoming call via the line control unit 11, drives the bells or speakers of the telephones 4 and 5 via the line control unit 11, and emits a ring tone. At the same time as this occurs, transistors 13 and 14 are driven. In this case, transistors 13 and 1
4 is driven by a signal that can blink the LEDs 22 and 32 in a fast cycle. The transistors 13 and 14 are turned on and off at the same timing, causing the LEDs 22 and 32 to blink. In so-called fashion telephones, the ring tone can be turned on and off as needed, but even if the phone is turned off, an incoming call can be detected by the blinking of the LEDs 22 and 32.

Next, for example, when transferring an outside call made with telephone 4 to telephone 5, the dial number for forwarding (for example, #2)
It will be placed on hold by operating . This state is 0
The signal is detected by the 020 unit 12, and the 020 unit 12 applies a signal with a long on/off period to the transistors 13 and 14. This causes the LEDs 22 and 32 to blink at a slow cycle. Therefore, when the above call arrives, L
The difference from the ED blinking can be easily distinguished.

Next, a case where an outside line is made from telephone a4 or a5 will be explained. When making an outside line, the line control unit 11 inputs a dial number (for example,
"0"). Next, enter the telephone number of the other party (area code - area code - 4-digit telephone number).

When the dial number "0" is operated, the 020 unit 12 applies a signal to the transistors 13 and 14 to cause the LIEDs 22 and 32 to light up continuously. This lighting indicates that the line is in use and cannot be used by other telephones, and by turning off the light, the user can know when the line will be available for use. Furthermore, LED2
2 and 32 are driven by the CPU 1 section 12 and transistors 13 and 14 so that they are lit continuously even when the extension telephone is in use.

In the above embodiment, only two telephones were used for convenience of explanation, but by strengthening the line switching function, five telephones were used.
~6 phones can be easily connected.

In addition, the line status is displayed using light emitting elements such as LEDs and lamps, but if quietness is not an issue,
It is also possible to use a piezoelectric buzzer or the like to make the recognition sound.

〔Effect of the invention〕

As explained above, according to the first telephone system of the present invention, the usage status of the line is monitored and the light emitting element or sound generating element provided in the modular outlet is controlled based on the monitoring result. Even when using a telephone, the line status can be easily grasped.
