Embodiment Construction

[0012] Embedded dialer of the present invention comprises 51 single-chip microcomputers, and the circuit of 51 single-chip microcomputers is equipped with Ethernet card chip additionally, and Ethernet card chip connects Ethernet interface, is implanted with Ethernet communication protocol in the program memory of 51 single-chip computers; Ethernet communication protocol is preferably It is PPPoE agreement, PPPoE agreement includes PPP module, LCP module, PAP module and IPCP module.

[0013] In the PPP protocol of the embedded dialer of the present invention, link control protocol (LCP), authentication protocol (PAP / CHAP), and network control protocol (NCP) are implemented in a modularized manner. Since only the IPCP protocol is implemented in the NCP protocol, the implementation of the PPP protocol in the present invention is subdivided into a PPP module, an LCP module, a PAP module and an IPCP module to implement respectively.

[0014] The embedded system of the present inven...

Abstract

Disclosed in the invention is an embedded type dialing device. The dialing device comprises a 51 single-chip microcomputer wherein an ethernet card chip is mounted in circuit; the ethernet card chip is connected with an ethernet interface; and an ethernet communication protocol is implanted in a program memory of the 51 single-chip microcomputer. The provided embedded type dialing device has the advantages of a high performance cost ratio and low access difficulty.

Description

technical field [0001] The invention relates to a network access device of a single-chip microcomputer, in particular to an embedded dialer. Background technique [0002] In recent years, various broadband access technologies have been promoted rapidly. ADSL technology and PPPoE technology have been recognized by operators and users with their unique advantages, and have made great progress in our country. The application of PPPoE on ADSL lines has become a broadband An important way to surf the Internet. The PPPoE protocol mainly establishes a logical communication link with the access concentrator at the link layer through the Ethernet driver in the system, creating conditions for the transmission of upper-layer PPP data packets. When sending data, the upper layer PPP packet is encapsulated into a PPPoE protocol frame and sent out. When receiving data, after analyzing the received PPPoE protocol frame, it is handed over to the upper layer PPP module for processing. With...
