3. Computes a raw estimate of the received SNR for each band.
4. Loads a reduced profile to measure the actual SNR.
5. Sets the optimal profile based on the actual SNR and the following parameters:
Monitoring the Optimal Link
Although monitoring is not mandatory, it helps management to track the link status and
recovers the link if failure occurs. The monitor runs on both LT and NT. See
for details.
During monitoring, firmware monitors link mode, BER and margin. If the link becomes
inadequate, firmware automatically reruns the RA algorithm.
If margin goes above or below defined thresholds, firmware recommends running the RA
algorithm again to set a new link configuration that is optimized for the new current SNR.
Management then decides whether or not to run the RA algorithm again.
