Embodiment Construction

[0021] figure 1 It shows a functional block diagram of a broadband access system in a preferred embodiment of the present invention. The broadband access system is mainly composed of a central office device 100 located at a central node (the part of the dashed frame in the upper left corner of the figure) and multiple remote devices 200 located at the remote end.

[0022] 1. Central office equipment

[0023] The central office device 100 in this embodiment is actually a broadband access device with a large capacity, for example, it can be a DSLAM (digital subscriber line access multiplexer), MSAN (multi-service access device, or integrated access device). Incoming equipment) or BLC (Broadband Loop Carrier, which is actually an implementation of MSAN).

[0024] The Switch Fabric 101 is an Ethernet-based switching network, which can provide multiple FE (Fast Ethernet) interfaces or GE (Gigabit Ethernet) interfaces, and complete the service exchange between these interfaces.

Abstract

Being related to broadband access, the invention solves issues of complex network management, high cost and low reliability in current system. Equipment at office end in broadband access system includes main control unit, exchange network unit, up going interface module, and xDSL interface module at office end etc. Equipment at remote end is equipment of broadband access in small capacity without independent control module; and basic units of equipment at remote end can provide multiple xDSL interfaces in order to connect to interface modules of remote end xDSL in modem or phone set at user side. The main control unit accomplishes control and management for each unit in equipment at office end as well as equipment at remote end. xDSL interface modules at remote end and at office end possess same function and principle of implementation. Through one or two up going fiber interface, cascaded equipment at remote end can connect to equipment at office end.

Description

Technical field [0001] The present invention relates to broadband access technology, and more specifically, to a broadband access system. Background technique [0002] With the popularization of broadband access construction, it is necessary to provide more and more users with broadband access services with higher bandwidth through twisted pair cables in order to carry out Triple Play (commonly referred to as triple services) services. Because the existing twisted-pair cables are usually long (some lines will exceed 3 to 5km in length), and long distances will cause the speed to drop, it is difficult to deploy broadband access equipment in the traditional CO mode to provide universal high Broadband access service with guaranteed bandwidth. At present, for such long-distance remote access users, the solution of placing small and medium-capacity remote access equipment closer to the user (such as the closest handover box to the user) is increasingly adopted. In this way, the length...
