Description

Key Phone Main Unit

1 is a schematic block diagram of a keyphone system constructed in accordance with the prior art.

2 is a block diagram of a key phone system and a key phone according to an embodiment of the present invention.

3 is a detailed connection block diagram of a key phone main device and a key phone according to an embodiment of the present invention.

The present invention relates to a key phone system, and more particularly, to a key phone main device capable of executing a user program in the key phone main device.

In the prior art, the key phone system is manufactured by separately separating the key phone main device and the key phone telephone, and thus, the user installs the main device system in order to perform a user program (MMC: Man Machine Communication) according to the user's request. I had to connect the phone. In addition, the maintenance of the key phone system is causing inconvenience because the location where the main device is installed and the location where the key phone is installed. That is, in the conventional key phone system, the key phone main circuit and the key phone telephone circuit are separated to manufacture a product using the key phone main device and the key phone telephone, which is inconvenient to install and maintain the system.

1 is a schematic block diagram of a key phone main device and a key phone telephone constructed in accordance with the prior art.

As in FIG. 1, the key phone telephone 102 is separated from the key phone main device 101, resulting in inconvenience due to distance problems during user program or maintenance. In addition, since the user program can be executed only after the key phone main apparatus 101 is installed, the key phone telephone 102 must be installed.

Accordingly, an object of the present invention is to provide a key phone main device capable of performing a call with a program and a subscriber in the main device.

Another object of the present invention is to provide a claim key key that can improve the convenience of installation and maintenance.

According to the technical idea of the present invention for achieving the above objects, an extension circuit for connecting to the extension subscriber in the key phone main unit and a call unit for forming a communication path with the user in the key phone phone, and the key phone main device It is characterized by mounting inside.

DETAILED DESCRIPTION A detailed description of preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

It should be noted that like elements and parts in the figures represent the same numerals wherever possible.

2 is a configuration diagram of a key phone system and a key phone telephone according to an embodiment of the present invention, and FIG. 3 is a detailed block diagram of a key phone telephone circuit mounted in the key phone system according to an embodiment of the present invention.

As shown in FIG. 2, one key phone telephone circuit 203 and its case are mounted in the key phone main device 201 case. The case includes a liquid crystal display (LCD) 204, numeric and function keys 205 arranged in a matrix of rows and columns, and a microphone and a speaker 206.

Referring to FIG. 3, the key phone telephone circuit 203 includes a transmitter 208 for mutual signal exchange with the internal circuit 207 in the key phone main apparatus 201, and overall control of the key phone telephone circuit 203. A main control unit (MCU) for converting a key, a key input unit 210 for converting a user's program and telephone number input into key data, and a liquid crystal display unit displaying a current operation state under the control of the main control unit 209 ( 211 and a call unit 212 for forming a call path with a user under the control of the main controller 209. In this way, one key phone telephone circuit 203 is mounted in the key phone main device 201 so that the call and the user program are basically enabled in the key phone main device 201.

By doing so, even after the installation of the key phone system and before the extension subscriber is installed, the key phone phone 203 included in the key phone main device 201 can check the operation state of the key phone main device 201 and the user program according to the function required by the user. The MMC is realized by the key phone main apparatus 201. It is also possible to conduct calls with external and internal subscribers.

As described above, the key phone main device according to the embodiment of the present invention has an advantage of allowing a user program in the main device. In addition, the present invention has the advantage that can improve the convenience of installation and maintenance.

Although the present invention described above has been limited to, for example, the drawings, the same will be apparent to those skilled in the art that various changes and modifications can be made without departing from the technical spirit of the present invention.
