Abstract

PROBLEM TO BE SOLVED: To attain control communication based upon cable connection and a radio relay by adding a transceiver to a controller and its relay and connecting also wire/wireless change-over switch. SOLUTION: A received signal received by a base station radio equipment is inputted to a relay 2-2' and corrected to a regulated level by an attenuator and an amplifier. When the wire/wirelss change-over switch is turned to a wirelss position, a transmitter is raised to execute transmission. When the relay 2-2' detects a voice in a received output, the rise of the transmitter is pressed. Since a controller 3 is previously set up to wireless communication so as to be matched with the relay 2-2', a signal is received by a receiver and outputted to a speaker as a monitor. On the other hand, a microphone input voice to the controller 3 is transmitted by a transmitter, received by a receiver in the relay 2-2' and transmitted to a base station radio equipment at a regulated level. When the relay 2-2' and the controller 3 are connected to a cable, the change-over switch 15 switched to wire side and communication voice is similarly transmitted/received. Consequently the controller 3 can be used in a movable state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improving the function of a wireless communication controller for controlling a base station wireless device via a telephone line so as to be cordless.

[0002]

2. Description of the Related Art In a conventional controller, as shown in the system diagram of FIG. 3 and the block diagram of the repeater and the controller shown in FIG. 4, the controller is fixedly installed due to the cable connection between the repeater and the controller. Therefore, it becomes a control call at a specific place. Therefore, it is inconvenient to make calls back and forth to the data shelf, monitoring monitor, etc. when making a call while looking at the materials and a request from the other party while watching the surrounding situation. There is. In FIG. 3, 1 is a base station radio,
2-1 to 2-2 are repeaters, 3 is a controller, 4 is an NTT leased line or a private leased line, and 5 is a premises cable.

[0003]

Since the conventional controller has a cable connection between the repeater and the controller, there is an inconvenience that the controller cannot be moved to make a control call. The purpose is to be able to use even if the controller is cordless.

[0004]

In order to achieve the above object, the present invention adds a transceiver to a controller and a repeater for connecting the same, and further installs a wired / wireless changeover switch to disconnect the conventional cable connection. However, it enables wireless communication between the repeater and the controller.

[0005]

As a result, a control call can be made by the conventional cable connection and wireless relay by switching the wired and wireless changeover switches of the relay and the controller.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to FIGS. FIG. 1 shows a system diagram of this system. The base station radio 1 and the repeater 2-1 are the same devices as in the conventional case, 4 is an NTT leased line or a private leased line, and 5 is a constituent cable.
The repeater 2-2 'and the controller 3'indicate devices each having a built-in wireless transceiver. FIG. 2 shows a block diagram of a repeater and a controller having the transceiver built therein. The received voice received by the base station radio as before passes through the repeater 2-1 and then is input to the repeater 2-2 'through the dedicated line 4. In the repeater, the level is corrected to the specified level by the attenuator and amplifier, and when the wire / wireless switch is switched to wireless, the transmitter is started up and transmitted. The transmitter is started up by pressing the voice detection of the received output at the repeater. Since the controller is switched to the wireless mode in advance according to the repeater, it is received from the receiver and output to the speaker as a monitor. On the other hand, the voice input by the microphone of the controller is transmitted by the transmitter, received by the receiver of the repeater, and transmitted from the base station radio via the repeater 2-1 at a specified level. . When the repeater 2-2 'and the controller 3'are connected by a cable, the changeover switch is switched to a wire, and the call voice is transmitted / received similarly.

[0007]

Since a transceiver is added to the conventional controller, the cost is high, but there is an advantage that the controller can be moved and used.
