G.821 performance results
Table 28 describes the G.821 performance results.
Event Log
The Event Log category displays the date and time that significant events,
errors, or alarms occurred during the course of your test.
Event Histogram
A histogram is a display or print output of test results in a bar graph format.
Histograms enable you to quickly identify spikes and patterns of errors over a
specific interval of time (seconds, minutes, or hours).
Frame relay results
The Frame Relay result category is divided into the following subcategories:
Summary, Clock, Control Signal, Data, DLCI, Link, Ping, LMI, DLCI List, Trace,
Event Log, Event Histogram. The results available in each subcategory are
listed in the following sections.
Summary results
The Frame Relay Summary result category displays a large “All Summary
Results OK” message if no anomalies or defects have been detected. If anom-
alies are detected, results are displayed.
Round Trip Delay Max The maximum round trip delay since the start of the test.
Only applicable when the BERT pattern is set to Delay.
Round Trip Delay Min The minimum round trip delay since the start of the test.
Only appears if using the BERT pattern is set to Delay.

Result Description
Verdict “Accepted” indicates that the test results have met the ITU-T Rec.
G.821 performance objectives.
“Rejected” indicates that the test results did not meet the perfor-
mance objectives.
ES Errored Seconds. The number of available seconds during which
one or more relevant anomalies or defects were present.
ESR Errored Seconds Ratio. The ratio of errored seconds to the num-
ber of available seconds.
SES Severely Errored Seconds. Seconds during which one or more
defects were present or the anomaly rate exceeded the ITU-T
Rec. G.821 threshold.
SESR Severely Errored Seconds Ratio. The ratio of severely errored
seconds to the number of available seconds.
UAS Unavailable Seconds. A count of the number of test seconds
which met the ITU-T Rec. G.821 definition of unavailable time.
