Problems solved by technology

[0011] Although using this method reduces the cost of the user interface board when only one bus is used, but because the backplane uses two kinds of buses at the same time, the complexity of the backplane is increased, resulting in an increase in the cost of the backplane

Embodiment Construction

[0054] The core of the present invention is to provide a unified bearing bus on the broadband access networking equipment, which can simultaneously bear ATM (Asynchronous Transfer Mode) and IP services without complicated conversion, and is convenient for different service types (ATM, IP) user interfaces to connect enter. At the same time, it provides a variety of user interfaces and uplink interfaces to meet the different networking requirements of different user access and broadband networks. The bus that uniformly carries the business can use high-speed serial LVDS (low voltage differential signal) bus, CML (current mode logic) bus, USB (universal serial) bus, and the rate can be adjusted between 200Mbps, 400Mbps, and 1Gbps to meet different requirements. The interface requirements of the device. ATM and IP services are carried by using the format of mapping ATM cells and IP packets into signal frames of the serial bus respectively.

Abstract

The disclosed device includes user interface board, main control board and back plate. The said user interface board and main control board through serial bus in high speed are connected to the back plate respectively. The method includes following steps: unitive loadbearing bus is provided through broadband access device; service information in different types is gathered together to the bus; according to their sorts, information is processed, and processed service information is sent to corresponding link. In the invention, bus carries services in different types without need of complex conversion, providing user interface access for services in different types as well as independent service interface. The invention simplifies structural design of back plate, and raises reliability of device.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a broadband access networking device and method. Background technique [0002] In the broadband access network system, the broadband user access equipment realizes the user line tandem function, aggregates data packets from users to one or more uplinks, and distributes data packets from uplinks to users below. Uplinks can be divided into two types: ATM (Asynchronous Transfer Mode) uplinks, which use ATM cells as encapsulation of data packets; IP uplinks, which use Ethernet frames as encapsulation of data packets. [0003] Broadband user access technologies used on subscriber lines include xDSL (Digital Subscriber Line) access, LAN (Remote Local Area Network) access, and HFC (Hybrid Fiber Coaxial) access. Although the principles of these technologies and the physical layer protocols used are very different from each other, the encapsulation of user data carried by ...
