Status Reports whether G.INP is in use for upstream or downstream.
Retransmitted DTUs Retransmitted DTUs. The number of retransmitted DTUs that were
received.
Corrected DTUs The number of DTUs the unit received a correction for.
Uncorrected DTUs Uncorrected DTUs. The number of DTUs that did not get a retransmission
(not received within the time limit).
INP Rein The effective impulse noise protection (INP) as a result of G.INP support.
