DSL Error Stats Screen – Model 8355 B-B-F
Displays errors encountered on a selected port during the current 15-minute period, the
previous 15-minute period, the previous hour, and the current day.
Enter a port name (dsl1–dsl24) to see current statistics.
ATU-R/ATU-C ES (Errored Seconds) – The number of errored seconds that have been
encountered on the port. An errored second is a 1-second interval during which one or
more of the following occurred: a Cyclic Redundancy Check (CRC) anomaly, one or more
or Loss of Signal (LOS) defects, one or more Severely Errored Seconds (SES), or one or
more Loss of Power (LOP) defects.
ATU-R/ATU-C SES (Severely Errored Seconds) – The number of Severely Errored
Seconds (SESs) that have been encountered on the port. An SES is a 1-second interval
during which 18 or more CRC anomalies, one or more LOS defects, one or more Severely
Errored Frame Seconds (SEFS), or one or more Loss of Power (LOP) defects have
occurred.
ATU-R/ATU-C UAS (Unavailable Seconds) – The number of 1-second intervals during
which the DSL line is unavailable. The line becomes unavailable after 10 contiguous
SESs or training. Once unavailable, it becomes available again after 10 contiguous
seconds that include no SES after training.
ATU-R/ATU-C LOFS (Loss Of Frame Seconds) – The number of 1-second intervals for
which a LOFS condition is declared after approximately 2.5 seconds of contiguous
Severely Errored Frame (SEF) defects. A Loss Of Signal (LOS) overrides it. A LOFS is
cleared after approximately 10 seconds with no SEF defect.
ATU-C LOSS (Loss of Signal Seconds) – The number of 1-second intervals during which
a LOS condition has been declared on the DSL line. A LOS is declared when no response
is received from the endpoint within 100 ms. The condition is cleared upon receipt of one
good frame.
ATU-R Loss of Power Seconds – A count of the endpoint LOP failures detected at the
line card (ATU-C). A LOP is defined as the receipt of 4 out of 6 dying-gasp messages from
the endpoint.
Current Interval Counter – How much time has elapsed in the current 15-minute interval.
