[Problem to be solved by the invention]

As mentioned above, in the conventional terminal address setting method, the terminal device and the terminal accommodation circuit each have an address memory for storing the terminal address assigned to the terminal device, and the source address is transmitted to the communication destination. and the destination address are placed at predetermined positions in the packet frame, so when assigning an address to a terminal device, it is necessary to register it in the terminal device and terminal address book, and to set it in the address memory of the terminal accommodation circuit. There is. Furthermore, when replacing a terminal device, it is necessary to change the memory settings of the address memory of the terminal device, which is time-consuming, and there is a risk that packet frames may not be transmitted and received normally due to incorrect settings.

An object of the present invention is to provide a terminal address memory and a unique address memory in a terminal accommodation circuit, and handle the terminal address for controlling connection with a communication destination separately from the unique address set in the terminal device. The object of the present invention is to provide a terminal address setting method that solves the above-mentioned problems by providing mutual address translation units for both devices.

[Means to solve the problem]

The basic configuration of the terminal address setting method of the present invention is that a terminal accommodating circuit that accommodates a terminal device that applies a predetermined packet switching method, connects to a high-speed transmission path, and transmits and receives transmission packet frames, performs connection control in a communication network. In a terminal address setting method in which a terminal address assigned to each terminal device for use is retrieved and stored in advance from a terminal address book that is registered in advance for each exchange system in advance, the terminal accommodating circuit has a terminal address memory and an address. In addition to the filter, it has a unique address memory, a destination address translator, and a source address translator.

The terminal address memory stores a terminal address assigned to a terminal device accommodated and connected by the terminal accommodation circuit, which is registered in advance from a terminal address book.

The address filter identifies a destination terminal address when a packet frame is received from the high-speed transmission path, and passes only the packet frame that matches the terminal address stored in the terminal address memory.

The fixed address memory stores in advance a unique address set independently by a terminal device accommodated and connected by the terminal accommodation circuit.

The destination address converter replaces the destination address of the packet frame received from the address filter with the unique address retrieved from the unique address memory and sends the packet frame.

The source address converter replaces the source address of the outgoing packet frame received from the terminal device with the terminal address taken out from the terminal address memory, and transmits the frame to the high-speed transmission line.

Further, one of the configurations added to the above configuration is a unique address book in which at least one unique unique address unified for each exchange system is registered in advance, and a unique address book provided in the terminal accommodation circuit and received by the source address conversion unit. a unique address detection transmitter that extracts and transmits a source address from a packet frame sent by the user; and a unique address detection transmitter that extracts and transmits a source address from the unique address detection transmitter, and compares the address received from the unique address detection transmitter with the unique address stored in the unique address book, and issues an alarm if there is a mismatch. and a central control unit having a collation unit that generates the data.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a functional block diagram showing one embodiment of the present invention. In FIG. 1, the same components as those shown in the conventional example of FIG. 2 are given the same numbers and symbols, and their explanations will be omitted.

In FIG. 1, a terminal device 10 and a terminal address book 3
9 is the same as the conventional one. Furthermore, of the terminal accommodation circuit 20, the packet identification section 21. High-speed code transmitter 22. High-speed code receiving section 23. The packet detection unit 24 and address filter 25 are the same as in the conventional case.

The terminal accommodation circuit 20 includes a terminal address memory 26 with an increased number of pressure lines as well as a unique address memory 27 . It has a destination address translation section 281, a source address translation section 29, and a unique address detection section 31. Central control device 3
0 has a collation unit 32, and in addition to a conventional terminal address book 39, a unique address book 38 is connected thereto.

The unique address memory 27 records the same address as the unique address memory 11 of the terminal device IO. In order to prevent erroneous settings, the unique address memory 27 is composed of, for example, a read-only memory, and is equipped with addresses specific to the exchange system in advance.

The destination address converter 28 extracts the destination address from the incoming packet frame that has passed through the address filter 25, replaces it with the unique address stored in the unique address memory 27, and sends it to the packet discriminator 13 of the terminal device 10. . Therefore, the packet determining unit 13 determines whether the address stored in the unique address memory 11 matches the destination address of the received packet frame, and imports the packet information into the terminal device 10.

Since the unique address memory 11 of the terminal device 10 has a structure in which the settings can be changed, the unique address detection section 31 of the terminal accommodation circuit 20 and the central control device 30 are used as means for detecting incorrect settings.
A verification unit 32 and a unique address book 38 are provided.

The unique address detection unit 31 is the source address conversion unit 29
Then, the source address is detected and extracted from the packet frame transmitted from the terminal device 10, and transmitted to the matching section 32. The collation section 32 of the central control device 30 compares and verifies the output of the unique address detection section 31 and the unique address stored in the unique address book 38, and generates an alarm when there is a mismatch. The storage device for the unique address book 38 also uses read-only memory to prevent incorrect settings.

Therefore, in an exchange system to which the method of the above embodiment is applied, the unique address of a terminal device brought in from another system and connected can be set to a single predetermined unique address, regardless of the assigned terminal address, and It can be used as is even if connected to any terminal accommodation circuit within the system.

In the above embodiment, the unique address memory 27 of the terminal accommodating circuit 20 is shown and described as independently recording unique addresses, but the information in the unique address book 38 can also be transferred and recorded under the control of the central controller. .

Further, although the unique address book 38 has been described as a read-only memory, it may be a memory whose settings can be changed from a control console connected to the central control device 30.

〔Effect of the invention〕

As explained above, according to the terminal address setting method of the present invention, the terminal accommodation circuit not only stores the terminal address used for communication network control, but also stores the unique address set in the terminal device, and stores the unique address and the terminal address. In addition to making the address irrelevant, the terminal device converts the source address at the time of transmission and the destination address at the time of arrival of the packet frame transferred between the terminal device and the communication network into a unique address and a terminal address, respectively. By unifying the unique address of the terminal device, it is possible to reduce the effort and chance of erroneous setting caused by changing the address setting when the terminal device is moved.

In addition, by unifying unique addresses, incorrectly configured addresses from terminal devices are retrieved and checked against the central unique address book.
It is possible to detect a mismatch and generate an alarm by using the packet frame sent from the terminal device, which has the effect of being able to notify of incorrect settings.
