Embodiment Construction

[0029] refer to Figure 2A As shown, the cell receiving and processing device in the DSLAM equipment includes a matching and forwarding unit, a matching correct indicating unit, a matching error indicating unit and an error cell header storage unit connected to the unit.

[0030] The matching and forwarding unit matches the permanent virtual connection information in the cell received by the user port with the configured permanent virtual connection information. For the correctly matched cell, the matching and forwarding unit outputs the cell matching correct information and forwards the correctly matching cell; for the incorrectly matching cell, the matching and forwarding unit outputs the cell matching error information and sends it to the error cell header storage unit Provides the cell that matches the error.

[0031] The matching correct indication unit receives and records the cell matching correct information output by the matching and forwarding unit.

[0032] The ma...

Abstract

The invention discloses a method for self-adaptive permanent virtual connection of a user digital line access multiplexer to solve the problems of complex configuration and high maintenance cost when opening broadband services in the prior art; the method is: detecting user digital Whether the user port of the line access multiplexer has only cell matching errors; when it is detected that the user port has only cell matching errors, obtain the virtual permanent connection information used by the user terminal from the cell header information of the user port matching errors; And delete the connection of the user port, and re-establish the connection according to the obtained virtual permanent connection information. The invention also discloses a cell receiving and processing device, which includes a matching and forwarding unit, a matching error indication unit, an error cell header storage unit and a matching correct indication unit.

Description

technical field [0001] The invention relates to broadband technology in the field of communication, and in particular to a method and device for self-adaptive permanent virtual connection of a subscriber digital line access multiplexer. Background technique [0002] With the development of telecommunication networks, more and more users are enjoying the convenience brought by broadband to their work, life and entertainment. Among many broadband access technologies, xDSL technology uses the existing twisted-pair cable resources as the transmission medium to meet different customer needs. It has developed and formed a variety of access technologies such as ADSL, SHDSL, and VDSL, and has won worldwide recognition. It has been widely used and achieved good economic and social benefits. [0003] Taking ADSL access technology as an example, its network application model is as follows: figure 1 shown. At the central office end (CO end), the digital subscriber access multiplexer ...
