Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] The present invention establishes an adaptive PVC (auto-sensing PVC) on the ATU-C, and the ATU-C automatically captures each PVC that has been configured on the CPE, and then automatically selects a PVC that supports the service according to the service type applied by the user and configures it in the On the central office access device, the service is established and user access is realized.

[0024] figure 2 The realization process of ADSL adaptive access provided by the present invention is shown, and the description is as follows:

[0025] In step S201, an auto-sensing PVC is configu...

Abstract

The adaptive access method for ADSL comprises: A. according to user business type, building adaptive PVC with package type same as user business; B. receiving the cell from user terminal to extract PVC message from cell and obtain the missing message of terminal device; and C. when the business accessing is abnormal, selecting one VPI / VCI value with package type same as the package type appointed during building the adaptive PVC from the obtained missing message to update the VPI / VCI value of the adaptive PVC, and connecting the PVC. This invention configures the auto-sensing PVC to automatic obtain the CPEPVC message for matching, and thereby saves maintenance cost for the provider.

Description

technical field [0001] The invention belongs to the communication field, in particular to a method and equipment for realizing ADSL access. Background technique [0002] Asynchronous transfer (Asynchronous Transfer Mode, ATM) is a connection-oriented transmission technology, using virtual connection, can support broadband asymmetric digital subscriber line (Asynchronous Digital Subscriber Liner, ADSL), integrated service digital network (Integrated Service Digital Network, ISDN) ) and other large-scale networks, providing various access services for various Customer Premises Equipment (CPE) users. Such as figure 1 As shown, only when the CPE connected by the twisted pair and the ADSL Transceiver Unit-Central Office End (ATU-C) have the same permanent virtual channel (Permanent Virtual Channel, PVC) setting, that is, the virtual channel identifier Only when the values ​​of (VirtualPath Identifier, VPI), virtual channel identifier (Virtual Channel Identifier, VCI) and the en...
