Abstract
The present invention comprises a remote terminal (20) and a central office (30) as part of and ADSL system (10). Once a communication channel is open between the remote terminal (20) and the central office (30), the remote terminal (20) transmits channel specific information, application specific information, or both to the central office (30). Once the central office (30) receives the information, the central office (30) can select data rate options optimized for the downstream receiver (the remote terminal (20)). Based on the application specific and/or channel specific information, the central office (30) can use a combination of calculations and look-up tables to formulate new options. When the remote terminal (20) sends channel specific information, the central office (30) can perform calculations which determine performance margins at various data rates.
