Example Embodiment

[0023] The following describes the present invention in further detail based on the drawings and embodiments:

[0024] Such as figure 2 As shown, the present invention provides a master-slave frame cascade system in an access device, including a master frame and at least one slave frame. The master frame includes a main control board, a backplane, and a line card. The main control board and the line card pass through the backplane. (Not shown in the figure) connection, the main control board includes an aggregation / switching module and an uplink interface module (that is, a WAN interface unit). The aggregation / switching module is respectively connected to the line card and the uplink interface module through the uplink interface module Establish a business channel with the upper-level convergence network; the slave frame includes a backplane and line cards. In addition, it usually includes a main control board without the convergence / switching module to perform some management tas...

Abstract

A master-slave frame cascade system in access equipment includes main frame at least one slave frame; wherein said main frame including master control board, backboard and line clip, master control board and line clip connected through backboard, master control board including concourse /switching module and uplink interface module, concourse/switching module respectively connected with line clip and uplink interface module, through uplink interface module establishing service channel; slave frame including clip; main slave frame respectively set transmitting/receiving module; main frame transmitting/receiving module connected with concourse /switching module, slave frame transmitting/receiving module connected with slave frame line clip through backboard; main and slave frame transmitting/receiving module connected through high-speed link, to make slave frame line clip directly through main frame concourse/switching module to make service concourse /switch .The present invention reduces system cost and IP address consumption.

Description

technical field [0001] The invention relates to the technical field of broadband access equipment, in particular to a master-slave frame cascade system in the access equipment. Background technique [0002] With the development of broadband access technology and construction, there are more and more broadband access methods, wider bandwidth, more and more services provided, and more and more users at the same time. Therefore, it is necessary to provide higher-density, lower-cost broadband CO (Central Office, end office) access equipment for operators and related customers. [0003] Such as figure 1 As shown, the broadband access device in the prior art generally includes a master frame device and a slave frame device, which are a unit. Wherein, the slave frame is a branch node of the master frame, and services are transmitted through the uplink channel of the master frame after being converged or switched by the master control board. Among them, both the slave frame and t...
