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...
