The present invention relates to a control system and a method for interworking an ATM with a frame relay using a human machine interface (HMI) instruction, which is an operation instruction for an operator in an ATM switch.

In a conventional ATM switch, a frame relay and an ATM interworking control method are as follows. That is, the frame relay subscriber is supported to be linked with the frame relay by performing the ATM PVC connection with only the ATM PVC connection VPI / VCI generated by registering the frame relay subscriber and then adding a DLCI (data link connection identifier) which is a frame relay connection. However, this method must have a dependency that an ATM PVC connection must be performed after a frame relay connection is performed. And since there must be ATM PVC connection with VPI / VCI generated by frame relay connection, there is no guarantee that it will succeed if ATM PVC connection with VPI / VCI generated by frame relay connection is performed. . In addition, such a frame relay and ATM interworking control method has an inconvenient management by making a frame relay connection and a dependency on performing an ATM connection, and the frame relay and ATM interworking control of the NMS managing the ATM switch. Inefficient management and maintenance.

As described above, in the conventional ATM exchange, in order to link the frame relay with the ATM, the operator registers the frame relay subscriber through the operator terminal, and then adds the DLCI which is the frame relay connection to provide the VPI / VCI corresponding to this DLCI. Upon receipt, an ATM PVC connection was made with that VPI / VCI. Since this VPI / VCI is not pre-occupied for ATM PVC connection, there is no guarantee that the VPI / VCI will be connected to frame relay and ATM interworking when the ATM PVC connection is made with this VPI / VCI. And ATM interlock control function is not reliable. In addition, there is a dependency that the ATM connection is performed after the frame connection must be performed, thereby reducing the efficiency of the operator and the NMS in managing and maintaining the frame relay and the ATM interworking control. In addition, the command to change the frame relay traffic parameters and the state change command to allow and prohibit the use of the frame relay subscriber and the connection are not supported to control the frame relay traffic and to allow the use of the frame relay subscriber and the connection. And many difficulties in prohibiting.

Therefore, the operator can perform the function of adding DLCI, which is a frame relay connection, and ATM PVC connection, independently from the ATM exchanger, eliminating the dependent order, and interworking only when the frame relay and ATM interworking are necessary. Frame relay with HMI commands, which makes it convenient for frame relay management, ATM PVC connection management, frame relay and ATM interworking control, and NMS can achieve high efficiency in managing and maintaining frame relay and ATM interlock control. An ATM interworking control method was inevitably required.

Accordingly, the present invention has been made to solve the above problems of the prior art, to independently perform the frame relay connection and ATM PVC connection to provide the frame relay and ATM interworking control function using the HMI command in the ATM switch. Frame relay subscriber registration, deletion, information output command, frame relay connection addition, deletion, information output command and frame relay and ATM interworking addition, deletion, information output command so that frame relay and ATM interworking can be interlocked when necessary. To provide a frame relay and ATM interworking control system and method that can provide efficient and convenient management and maintenance by providing frame relay traffic parameter change command and frame relay subscriber state change and frame relay connection state change command. There is this.

In order to achieve the above object, the frame relay and the ATM interworking control system in the AT switch according to an embodiment of the present invention checks whether the HMI (Human Machine Interface) commands and parameters input from the operator terminal conform to the command format. A HMI and transfer function unit (HANDF) for requesting the HMI command processing and displaying the HMI command processing result to the operator terminal;

In addition, the frame relay and the ATM interworking control method in the ATM switch according to the present invention, when the HMI (Human Machine Interface) commands and parameters are input from the operator terminal, HMI command type checking step of checking the format error of the HMI command Wow;
A parameter checking step of checking a parameter error of the HMI command if there is no error as a result of the HMI command type checking step;
