Init This field displays the number of link-ups and link-downs.
ATUC/ATUR ES The Number of Errored Seconds transmitted (downstream) or received
(upstream) on this ADSL port.
ATUC/ATUR
SES
The Number of Severely Errored Seconds transmitted (downstream) or received
(upstream) on this ADSL port. Severely errored seconds contained 30% or more
