Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a slave telephone for home telephone use that is connected to a telephone outlet.

(Prior art) In order to improve operability, conventional dedicated telephones for home phone subphones are equipped with dial buttons for making outside calls and for making internal calls, operation buttons for receiving outside calls, transfers, and receiving internal calls, and a busy display. It has various functions such as a light emitting diode for use.

(Problems to be Solved by the Invention) However, in the case of home telephony systems, particularly in children's rooms, an outside line calling function may not be necessary. In this case, conventionally, calls have been restricted using special specifications.

Therefore, in such a case, unnecessary functions must be regulated, which increases the cost accordingly.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a low-cost slave telephone for home use without unnecessary functions.

[Structure of the invention]

(Means for Solving the Problems) The slave telephone for home telephones of the present invention connects one indoor exchange and a telephone outlet to which a plurality of individual telephones can be connected by multi-drop wiring, and the telephone outlet , and can make and receive internal calls and receive outside calls.
It has a transfer means.

(Function) The present invention connects individual telephones to a plurality of telephone outlets to which an indoor switchboard can be connected using multi-drop wiring, connects individual telephones to these telephone outlets, and connects home telephones to other telephone outlets. Connect your child phone. Then, the user operates the means for making and receiving extension calls, and receiving and transferring outside calls on the home telephone subphone, and makes and receives calls on the corresponding extensions, and receives and transfers outside calls.

(Embodiment) Hereinafter, an embodiment of the home telephone slave telephone of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes an indoor exchange connected to an outside line and a commercial AC power source of, for example, AC 100 (V), and from this indoor exchange 1, a call/signal line 2 is connected to a plurality of telephone outlets 3 installed in the room. ing.

This telephone outlet 3 has a function as an adapter to which a standalone telephone 4 can be connected, and a standalone telephone ta4 is connected thereto, as well as a slave telephone 5 for home telephone use.

This home telephone subphone 5 has a receiver 6.
, a speaker 7 used for ring tones, voice calls, etc., a light emitting diode 8 for busy indication, a microphone 9 used for hands-free calls, etc., which allows you to talk without holding the receiver 6, and making and receiving extension calls and transferring outside calls. In other words, the telephone is equipped with an operation button 10 as a means for making a call, and thus the telephone is obtained by removing the dial for making a foreign call from a conventional home telephone sub telephone.

Then, the indoor exchange 1 performs system management using signals according to the dialing of the stand-alone telephone 4, the incoming/outgoing/transferring of outside lines, the incoming/outgoing/incoming/outgoing extensions, the incoming/outgoing calls of the home telephone subphone 5, and the incoming/outgoing calls of extensions. Make outside and internal calls.

In case of external line transfer, a voice notification will be given.

Further, when the call/signal line 2 is in use, the light emitting diode 5 for busy indication lights up.

When receiving an outside line, the incoming call is automatically answered, and transfer is performed using the operation button 10. For extension calls, press button 10 for both making and receiving calls.
Let's do it.

〔Effect of the invention〕
