[Problems to be Solved by the Invention] 1. However, in the conventional cordless telephone device described above, an isolator or the like is provided to prevent transmission IM in order to configure a plurality of radio units in the same base station, and the number of radio units that can be stored in one housing is limited. It is not possible to enable the wireless because there are few effective wireless channels available in one system, and there is a terminal block to connect the intercom slave to the base station. Due to the installation location, the base station could not be installed in an ideal place (where it is always used), so there were problems such as wireless connection errors and call noise. 2. However, in the above-mentioned conventional cordless telephone apparatus, the mobile station can be wirelessly connected only to a fixed base station, and the wireless unit in the base station within one system is fixed, so that the other mobile station is not in use while the mobile station is in use. There was a problem with the number of radio units in the base station that could not be used. 3. However, in the above conventional cordless telephone device, when another base station is connected to this system, it takes a long time to ring because the time to use that channel is divided in order to prevent contention of the wireless channel when receiving a call. There was a problem.

The present invention solves these conventional problems, and an object of the present invention is to provide a cordless telephone device capable of constituting a plurality of mobile stations in the same system.

[0008]

In order to achieve the above object, the present invention provides: The wireless units suitable for the main device are distributed one by one, and they are configured as one base station, and the base station is connected to a plurality of systems, and the terminal block and the like are provided in the main device. It is possible to connect with and by the bus line, the installation position of the base station can be made ideal, the isolator for the countermeasure against the transmission 1M is abolished, and the wireless channel is effectively used. 2.1 By connecting a plurality of the above-mentioned base stations to a system on a bus line wired from the main unit, and communicating the status information of the mobile stations in the system on the bus line, and by sharing a plurality of common base stations. Connect the mobile station. (M:
N connection) 3. A setting unit is provided in the base station, the system is divided into groups according to the setting, and mobile stations in one system are additionally connected.

[0009]

Therefore, according to the present invention, 1. By configuring a plurality of base stations having one main unit and one wireless unit in a distributed manner, a connection terminal block for connecting the intercom slave unit is provided in the main unit, and an ideal place for installing the base station ( It can be installed in the place where it is always used, and can be used without any wireless error or call noise. Further, since the base stations can be separated from each other, it is possible to eliminate the isolator, which was included as a measure against the transmission IM, and thus to effectively use the wireless channel. 2. In addition, data communication that one mobile station is using the wireless unit is carried out to other base stations on the extension bus line, and the remaining mobile stations can be wirelessly connected to the other base stations. Two or more units can be connected and installed according to the number of mobile stations you want to use. 3. Further, by dividing the control channel according to the setting, the above-mentioned wireless system can be configured as two systems, and base stations and mobile stations can be added.
