Embodiment Construction

[0038] Embodiments of the present invention will be described below in conjunction with the accompanying drawings. Chip 1 is the core chip of the high-speed PLC local end equipment. It can receive the end-user Ethernet frame from the high-speed PLC user-side interface and the search frame from the user-side modem itself through the coupling signal. The chip can extract the end-user's MAC address and the user-side The modem modulates its own administrative MAC addresses, and sends these MAC addresses to the chip 2 . Chip 2 stores the legal MAC address table set by the administrator. If the MAC address sent by chip 1 to chip 2 appears in the legal MAC address table, chip 2 sends a receiving / forwarding permission response to chip 1, and chip 1 forwards the Ethernet frame sent by the end user, or sends a message to the user end The modem responds with a search frame from the modem. If the MAC address sent by chip 1 to chip 2 appears in the legal MAC address table, chip 2 sends ...

Abstract

Combined using two chips: integrated power line media access control / physical transceiver in device at bureau side, and power line media access address controller realizes access control for users' validation from broadband access in process of data through power line transferred from bureau side to terminal device. Configuring MAC address of new validated user onto power line media access addresscontroller (chip 2) at remote side, service provider controls only legal registered user is permitted to access Internet.

Description

technical field [0001] The invention belongs to the communication field, and is a high-speed electric power line communication local end equipment. Background technique [0002] Network technology has been widely used, and there are two main data access methods currently in use: telephone line access and data line access. The telephone line access method is to use the telephone line of the telecommunications company to connect the data from the central office equipment to the user terminal, and then separate and use the data through the modem. This is also the Internet access method currently used by individual household users, including dial-up Internet access, ISDN, ADSL and other methods. The data line access mode is to connect data to the user terminal through a data line commonly referred to as a "network cable". This is the data access form of LAN broadband used by general units. The terminal computer that needs to access the LAN is connected to the local end device ...
