The interworking configuration information includes types and numbers of network matching devices to be communicated with and related management data such as user level, link level, and Ethernet level.

The user management module 420 is a virtual circuit for a user call through the user access module 500 by users of the Ethernet interworking unit 400 such as the operation service processing unit 332, the subscriber processing unit 312, or the service processing unit 322. To set up the call, use the discrimination function on the call setup parameters to determine whether to allow the call. In addition, when trying to transfer user data through the Ethernet network, it is determined whether the access according to the state of the call connection control module 470. In addition, the user management module 420 obtains call connection information and connection network type information of communication target network matching devices in connection with the service management module 430 and uses these information as control data when setting up a call.

The device identification module 450 obtains the existence of communication target network matching devices and related address information, and based on this, the link control module 480 instructs link setting or release between the network matching devices.

The network matching management module 460 performs an initialization function of the interworking network, the Ethernet network, and manages the failure of the Ethernet network. When a failure occurs, this fact is transmitted to the interlocking management module 410, and the interlocking management module 410 notifies other network matching devices of the communication disconnection fact of the Ethernet interlocking unit 400.

The device identification module 450 is a function for obtaining Ethernet addresses of network matching devices connected to the Ethernet network. An Ethernet address is required for network matching devices to communicate in an Ethernet network, and this Ethernet address should be associated with a logical address of a network matching device used when accessing the Ethernet interworking unit 400.

Virtual line establishment / release between users When the call connection control module 470 receives the virtual line establishment / release from the user, the call connection control module 470 converts the call connection level control packet to another network matching device through the link control module 480. By passing to the call connection control module 470, and receiving the corresponding packet. The set state of the virtual circuits is managed by the virtual circuits in the call connection control module 470.

In order to support data transmission of users, a user data transmission queue 471 and a user data reception queue 472 are allocated for each virtual line when the virtual circuit is set up. If the user data is in the transmission queue 471, it is converted into a call connection level data packet and transmitted through the link control module 480 to a call connection control module of another network matching device having a virtual circuit. On the contrary, upon receiving the call connection level data packet from the call connection control module of another network matching device having the virtual circuit set, the user data is extracted and put into the user data receiving queue 472. Read the data.

The link control module 480 sets up virtual links established between network matching devices, manages state information of these links, and is responsible for reliable transmission between devices. The virtual link is established by exchanging link level packets with the link control module 480 of the network matching device according to the information of the network matching devices to be communicated from the link management module 440.

The Ethernet matching module 490 configures data to be transmitted by the device identification module 450 and the link control module 480 into an Ethernet frame and transmits and receives the data through an Ethernet network.

That is, the subscriber network matching devices connect the virtual network with the service network matching devices without establishing a virtual link with the subscriber network matching devices. In this case, as described above, the virtual link may be selectively set. At the virtual line communication level in the virtual link connection state, the virtual lines may be variously set according to their communication capability between network matching devices. The subscriber network matching device # 1 can set a total of 96 virtual lines by setting 64 virtual circuits with the service network matching device # 1 and 16 virtual circuits with the service network matching devices # 2 and # 3, respectively. The subscriber network matching device # 2 may establish a total of 32 virtual circuits by setting 16 virtual lines with the service network matching devices # 2 and # 3, respectively.
