Abstract

PURPOSE:To perform easily the connection of outgoing and incoming call even when the signal system of an opposite circuit is not clear. CONSTITUTION:A CPU 4 gives a selection signal of a subscriber 7 of an opposite station to a signal system automatic recognition section 3. The signal system automatic recognition section 3 starts a trunk 2 to monitor the interface of the trunk 2 for a signal from an opposite station exchange 6, the CPU 4 revises several kinds of signal systems till a subscriber replies an outgoing and incoming call and recognizes the signal system used for the reply when the subscriber replies the call. Then the CPU 4 sets the result to a memory 5, learns and recognizes automatically the signal system at the incoming call and the outgoing call to make incoming outgoing communication.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic exchange, and more particularly to an electronic exchange capable of automatically recognizing a signaling system.

[0002]

2. Description of the Related Art Conventionally, electronic exchanges perform connection processing based on a subscriber's signaling system. As for the opposing circuit (trunk or the like) of this electronic exchange, it is necessary to register its signal system in advance or to use a circuit adapted to the signal system.

[0003]

However, in this conventional electronic exchange, if there is an error in the registration method or an error in the circuit selection when the signal system of the opposite circuit is unknown, the opposite communication is not possible. There was a problem that it could not be done.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an electronic exchange capable of easily making incoming and outgoing connections even if the signal system of the opposing circuit is unknown.

[0005]

In order to achieve the above object, the electronic exchange of the present invention is an electronic exchange that performs connection processing based on a subscriber's signaling system. Learning for learning the above signaling system at incoming and outgoing calls. A means is provided so that incoming and outgoing connections can be made even if the signal system of the opposing circuit is unknown.

[0006] Then, if necessary, the learning means changes the signal system changing function to several signal systems until the subscriber responds to the incoming and outgoing call, and the signaling system that responds when the subscriber answers the call. It has a cognitive function to recognize.

[0007]

According to the electronic exchange having the above-described structure, the signaling system is learned at the time of incoming and outgoing calls, whereby the signaling system is automatically recognized. Therefore, the connection processing based on the signal system of the opposing circuit becomes possible.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of an electronic exchange according to an embodiment of the present invention.

In the figure, reference numeral 1 is a switch for connecting to an opposite exchange 6 via a trunk 2. Reference numeral 7 is an opposite station subscriber connected to the opposite station switch 6.

Reference numeral 3 denotes a signal system automatic recognition unit related to the learning means, which activates the trunk 2 in response to a selection signal, monitors the interface of the trunk 2 and responds when the subscriber makes an incoming or outgoing response. It has a cognitive function to recognize the method.

Reference numeral 4 is a CPU relating to the learning means, and the signal system automatic recognition section 3 receives selection signals relating to several signal systems.
And a change function for sequentially changing several kinds of selection signals until the subscriber answers the call. Also, CPU
Reference numeral 4 has a writing function for writing the signal system recognized by the signal system automatic recognition unit 3 in the memory 5.

Next, the process of recognizing the signaling system with the opposite station will be described.

First, suppose that the call origination is performed, but the signaling method can be recognized because the subscriber 7 of the opposite station is in a response state. The CPU 4 gives the selection signal of the subscriber 7 of the opposite station to the signal system automatic recognition unit 3. The signaling automatic recognition unit 3 activates the trunk 2. Then, the connection confirmation signal (for example, no connection confirmation signal, wink system, revers system) can be determined by monitoring the interface of the trunk 2 for the signal from the opposite station exchange 6.

Next, the selection signal is, for example, DTMF (multi-frequency signal system), dial pulse system (10 pps / 20).
pps) in order, and the signaling system at the time of transmission is recognized when the opposite station subscriber 7 can respond. When the transmission signal system is determined, the signal system automatic recognition unit 3 sends the result to the CPU.
4, and the CPU 4 sets it in the memory 5.

On the other hand, in the incoming signal system, the CPU 3 gives the signal system automatic recognition section 3 numerical information to be received. The signal system automatic recognition unit 3 changes the received signal system until the counter exchange 6 receives the call on the trunk 2 and sends the previously set numerical information and can receive it correctly. When the reception signal system is determined, the result is set in the memory 5 via the CPU 4.

[0016]

As described above, according to the electronic exchange of the present invention, by providing means for learning the signal system at the time of incoming and outgoing, even if the signal system with the opposite exchange station is unknown, It is possible to automatically recognize the call and to easily perform incoming and outgoing communication.
