JP2000013522A - Computer communication method using indoor telephone line and computer connected by radio - Google Patents

Abstract

PROBLEM TO BE SOLVED: To use a computer without the limitation of the installation place of the computer and to conveniently use it by connecting an indoor telephone line and the computer through radio. SOLUTION: When the indoor telephone line is an ISDN circuit, the computer 1 is connected to the indoor telephone line via a master and slave radio equipment 4 and 5 and an ISDN terminal 11. When the indoor telephone line is an analog circuit, an extension telephone is utilized, a terminal telephone cord terminal for a modem is laid to a telephone set slave unit, and the computer and the indoor telephone line are connected.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a computer communication circuit and a device for wirelessly connecting an indoor telephone line to a computer.

[0002]

2. Description of the Related Art A telephone cord connects an indoor telephone line to a computer.

[0003]

Since the indoor telephone line and the computer are connected by a telephone cord, the installation place of the computer is limited, which is inconvenient in use. Further, when extending the telephone cord to a place where the computer is to be placed, it is necessary to make a hole for the telephone cord in a wall or the like or to crawl the telephone cord on the wall or the like, which is inconvenient in use.

[0004]

According to the present invention, an indoor telephone line and a computer are connected by a radio circuit.

When the indoor telephone line is an ISDN circuit, the indoor telephone line is connected in the order of ISDN line-TA-radio master unit, and the computer side is connected to the radio slave unit-computer, and the radio base unit is connected. Computer communication with the wireless device

[0006] When the indoor telephone line is an analog line, a parent-child telephone is used, and the connection is made in the order of a telephone sub-unit, a modem and a computer.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A telephone (8) has a modem (1).
0) Laying telephone cord terminals (13) for connection.

When computer communication is not performed, the telephone cord terminal plug (19) is removed from the telephone cord terminal (13) of the telephone handset (8) and used as a normal telephone handset (8). The structure is easy to attach and detach.

[0009] The telephone handset (8) has a call waiting / signal sound enlargement function for recognizing call waiting during computer communication.

The wireless master unit (4) is replaced with a TA for ISDN (2)
Built-in.

【The invention's effect】

In the present invention, since the connection between the indoor telephone line and the computer is made wirelessly, there is no restriction on the place where the computer is installed, which is extremely convenient.

There is also a method of connecting a PHS or a mobile phone to a computer to perform computer communication without using an indoor telephone line, but the communication fee is high. Since the present invention uses a telephone line, the communication cost is low.

In the case of using a parent-child telephone, it is only necessary to lay a telephone cord terminal on the telephone sub-unit, connect a modem, and add a function of enlarging call waiting and signal sounds.

When a parent-child telephone is used, there is a call-waiting signal / signal sound enlargement function. If there is a telephone during computer communication, the computer operation can be held and the telephone slave can be used. Alternatively, computer communication is possible without any difficulty using only the current indoor telephone line without using a dedicated computer line.
