Abstract

PURPOSE:To automatically connect a telephone set to an order telephone line of another system by means of simple operation and to call and speak with a person on the line by providing a patch connection requiring code transmitting/receiving function and a patch connecting function to a normal selective call function. CONSTITUTION:In a station B which is simultaneously equipped with the telephone lines of the respective systems, a patch connection requiring code receiving circuit 4 and a patch connecting circuit 5, which form a means to patch- connect the telephone lines of the respective systems, on the other hand in respective stations A, C and D, a patch connection requiring code transmitting circuit 3, which forms a patch connection requiring means, is provided. When the station A calls the station C and speaking is established, a patch connection requiring code is inputted from a key provided in a selective calling circuit 2 in the station A. The input is received by the patch connection requiring code receiving circuit 4 provided in the station B, the patch connecting circuit 5 is controlled, the order telephone line to which the station C is connected is connected, and a patch connection completing signal is returned to the station A. Thus the speaking between the stations A and C are established.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a meeting telephone device, and more particularly to a simple meeting telephone device useful for use in maintenance of microwave communication line systems.

(Prior Art) Conventionally, in this type of meeting telephone system, when it is necessary to patch-connect meeting telephones between different systems, there are systems in which an operator is assigned to the station where connection is required and the connection is made artificially. It was a system that remotely controlled the connection of meeting telephones of different systems using a separate remote control device.

(Problem to be Solved by the Invention) In the conventional meeting telephone system described above, the former system requires an operator to be assigned and connect manually, so it cannot be connected if the operator is not present. However, since the latter system must be equipped with a separate remote control device, it has the problem of high cost.

The present invention was made to solve these problems, and it is possible to automatically connect a meeting telephone line of a different system with a simple operation, and call a station connected to another system to make a call. The purpose of the present invention is to provide a meeting electric packing device that is capable of performing the following tasks and has a low equipment cost.

(Means for Solving the Problems) A meeting telephone device according to the present invention includes a circuit network for arbitrarily patch-connecting a plurality of independent meeting telephone lines, and a patch connection request code for controlling the patch connection. A patch connection request code transmitting/receiving circuit that transmits and receives a patch connection request code, a patch connection completion signal transmitting and receiving circuit that transmits and receives a signal indicating that the patch connection is completed, and a patch connection disconnection signal that instructs to disconnect the patch connection after the end of the call. and a patch connection disconnection signal transmission/reception circuit.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a configuration of a meeting telephone device according to an embodiment of the present invention.

This embodiment shows a case where stations A, C, and D, which are connected to meeting telephone lines of different systems, are connected by station B. Here, station B is a station that is equipped with meeting telephone circuits of multiple systems at the same time. , A, 0, and D are stations equipped with only one system of meeting telephone circuits.

Each of stations A, B, C, and D is provided with a meeting telephone circuit 1 and a selective calling circuit 2, so that within the same system, the selective calling circuit 2 can call the other station and talk to it. In addition, station B has telephone circuits for each system at the same time.
A patch connection request code receiving circuit 4 and a patch connection circuit 5 are provided, which form means for patch connection of the telephone lines of each system, while stations A, 0, and D have patches forming patch connection request means. A connection request code transmitting circuit 3 is provided. Note that 6 in the figure is a three-way branch circuit that performs relay connection of lines.

The operation when calling a station connected to a meeting telephone line of another system and making a telephone call will be described below.

For example, when calling station 0 from station A to make a call, first, a patch connection request code is input from a key attached to the selective calling circuit 2 of station A.

Then, the patch connection request code transmitting circuit 3 sends out a patch connection request code, which is received by the patch connection request code receiving circuit 4 provided in the B station to control the patch connection circuit 5.

The patch connection circuit 5 connects the meeting telephone line to which the A station is connected to the meeting telephone line to which the 0 station is connected, and sends back a patch connection completion signal to the A station.
After confirming this patch connection completion signal at station A, when the selective calling circuit 2 of station A is operated again to send out the calling code for station 0, this calling code is received at station 0 and A
After completion of one call in which communication between the station and the 0 station is possible, the A station sends out a call termination signal, and the patch connection request code receiving circuit 4 of the B station receives this, thereby cutting off the patch connection circuit 5.

Note that the present invention is not limited to connection between two systems, but also allows connection between three or more systems. In that case, a patch connection request code is sent to each station having each patch connection circuit to be connected.

(Effects of the Invention) As explained above, the present invention adds a patch connection request code to the normal selective call code by providing the patch connection request code sending/receiving function and the patch connection function in addition to the normal selective call function. With a simple operation, you can automatically connect to other system's meeting telephone line and call the station connected to Ike's system and make a call.

Moreover, the equipment cost is lower than that of installing a separate remote control device.
