ES - Errored Seconds. Reports the duration of the incoming BIT errored blocks
per seconds, the percentage of errored seconds compared to the duration of
error free seconds, and the S1 and S2 percentage.
•
SES - Severely Errored Seconds. Reports the duration of Severely Errored
Seconds (SES), rate percentage, and the S1 and S2 percentage on the incoming
SDH signal. An SES is reported when the number of BIT errors per second
equals or exceeds 2,400 errors per second for HP mappings or 600 errors per
second for LP mappings, or when an LOS alarm, OOF alarm, LOF alarm, MS-
AIS alarm, AU-LOP alarm, AU-AIS alarm, HP-UNEQ alarm, TU-AIS alarm, TU-
LOP alarm, or TU-LOM alarm is present.

Perf Monitor - M.2120 / M.2110
(Specifically for SDH testing)
The M.2120 / M.2110 screen provides a detailed breakdown for errors detected and
logged by the SDH protocol processor by using threshold error performance criteria with
respect to either a 15-minute (TR15) or 24-hour (TR24) evaluation period.
Error thresholds can be set directly from the M.2120 / M.2110
The following statistics appear on the M.2120 / M.2110
Statistic Description
Event Lists the error type and error.
TR15 Threshold Report 15-minute evaluation period. A TR is an error
performance report with respect to a 15-minute evaluation period.
There are one TR15 and one Reset TR15 (RTR15) for each
performance event.
The start and end time for the 15-minute evaluation window must
occur on the hour and at 15, 30, and 45 minutes with respect to the
elapsed time for each test. The TR15 evaluation period occurs as
soon as the 15-minute threshold is reached or exceeded. If the
