However, in the prior art, a plurality of protocols received in an access network were received at an exchange and the protocols of the access network and the exchange were designated as a necessary protocol based on the received contents, and then communicated through the designated protocol. If the protocol could not be unified again between the access network and the exchange after an error occurred, there was a defect that the collision between the access network and the exchange occurred during the call progress.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks of the prior art, and the V5.2 matching common control protocol processing function has system data between systems between the exchange and the access network and returns to normal when an error occurs during operation. The purpose is to provide a means for operating after receiving system data from one place and unifying it.

In order to achieve the above object, the present invention provides a matching network performing a matching function with external devices of a system through control of a line controller (not shown), and performing a function of separating and controlling a V5.2 matching protocol. A V5.2 matching control unit, a V5.2 subscriber control unit for processing, operating and maintaining a call of a V5.2 matching subscriber, and a V5.2 data processing unit for processing a V5.2 subscriber data. Therefore, when the preset exchange system is rebooted, the matching network transmits a common control signal that the system has lived to the exchange, and the exchange receives the system information change request and changes the corresponding system information change information; When the exchange transmits system change information to the V5.2 matching controller, the exchange transmits an authentication signal for a common control authentication signal to the matching network. It provides a V5.2 matching common control protocol processing method comprising the step of loading the system by the system information change information after comparing with the predetermined data.
