Method and system for establishing and maintaining a broadband link

摘要

The system has a master post (10) transmitting a known test sequence to a called post (11) upon acknowledging the fact of switching to probing mode to determine the best configuration for link establishment. The called post includes a controller (17) to determine quality scores on Mk frequencies of a sub-band, and transmit the quality values to the master post that determines the capability of the sub-band to respond to a service level agreement (SLA) target service, and selects the sub-band representing the required capability for triggering communication with the called post. An independent claim is also included for a method for broadband ALE link setup and link sustaining between a master communication post and a called communication post.
