Description

Keyphone Type Wire / Wireless Telephone Device {Keyphone Type Wire-based and Wireless Telephone System}

The present invention relates to a keyphone type wired / wireless telephone. More specifically, the key phone type wireless telephone apparatus is divided into a repeater (I), a cordless telephone (II), and a wired telephone (III), and a key phone type for preventing crosstalk when used by multiple users by adding a wired communication unit to the repeater. It relates to wired / wireless telephones.

In general, a key-phone type landline telephone used in an office is configured to be connected by a wired telephone line, so it is inconvenient in that a telephone construction must be renewed every time the installation of the office is changed. In addition, as the telephone line is exposed to the outside, a poor connection failure due to an external shock occurs frequently.

However, due to the development of information and communication technology, a wireless telephone that overcomes the shortcomings of the wired telephone has been developed, which adds a lot of convenience. In the case of a conventional wireless telephone, a single telephone can be used by several people by connecting a plurality of handsets to a single main body. However, as all functions are integrated into a handset of a radiotelephone and increasingly smaller and lighter, they are not suitable for use in office or home reception sets. In addition, even when the main body is mounted, a telephone line and a DC power supply line are required, which causes many problems in terms of layout and space utilization. In particular, wireless modems are being used in accordance with the spread of communication devices such as computers, but they are not widely used as telephones because they are inconvenient to use and unsuitable for voice calls.

In order to solve the above problems, the present inventors connect a transmission / reception relay device to a telephone line and configure a cordless telephone corresponding thereto such that a receiver and a main body are connected by a coil cord to a cordless telephone. It was filed in 97-23515. According to the present invention by providing a handset-type cordless telephone in the form of a wire cord with a cord cord can solve the problem of uncomfortable to put in the reception set of the office and home and can expand the dial keyboard to facilitate the use of the elderly and various You can design the product in the form.

In addition, the present inventors installed an internal telephone call forwarding and forwarding function by installing a wireless telephone line transmission / reception relay device of a whole line and a corresponding wireless telephone in a terminal box and adding a decoding circuit of a line switching device in order to expand its function for office use. Filed with a domestic phone application No. 97-50759. Particularly, in an office environment such as a conference room, the telephone should be fixed stably, so a cordless telephone in the form of a wired telephone as in the above invention is preferable, and a key-phone type wireless telephone apparatus which inserts a card-type transceiver into a terminal box by eliminating the telephone wiring of an office. Has the form of.

However, the key-phone type wireless telephone according to the present invention can use up to 30 people at the same time, but up to 10 people at the same time, but the bandwidth is limited, so there is a risk of confusion when used by a large number of users. In addition, there is a technical difficulty in initializing the transmission and reception relay device, it is inconvenient to control when the relay device is installed, and in the computer communication, the wireless method is less reliable in communication than the wired method.

In order to overcome the above problems, the present inventors have developed a wired / wireless telephone apparatus which is a combination of wireless and wired methods so that a telephone that needs to communicate by wire can be connected by wire.

SUMMARY OF THE INVENTION An object of the present invention is to provide a key-phone type wired / wireless telephone apparatus that allows a user who does not need to connect wirelessly by adding a wired communication function to a transmission / reception relay device and a user who has difficulty installing a telephone line. Another object of the present invention is to provide a key-phone type wired / wireless telephone apparatus that can overcome the problems of crosstalk caused by use by a large-scale user and the difficulty of initiating a transmission / reception relay apparatus. Another object is to provide a key-phone type wired / wireless telephone apparatus that can use a wireless telephone by installing a wireless transmission and reception circuit module in the wired transmission and reception portion of the key phone installed in the existing office.
