Upstream Power
What is UPBO?
Upstream Power
Strong FEXT generated by short loops can significantly degrade the performance of long loops if UPBO is not applied. On the other hand, UPBO reduces the transmit power of short loops and thus degrades their performance as well.

Enable UPBO to allow the system to adjust the transmit PSD of all lines based on a reference line length so that the PSD at the receiving end is the same.
