ESMC Monitoring
ESMC (Ethernet Synchronization Message Channel) is a live value
monitored even when the test is not started. The arrow next to the
ESMC label indicates that ESMC valid information frames are received
or not.
A green arrow indicates that at least one ESMC valid information
frame, containing a valid FCS, was received within a second in the
last 5-second interval.
A red arrow indicates that no ESMC valid information frames were
received for more than 5 seconds.
A gray arrow indicates awaiting incoming data to provide a status.
Received QL indicates the received Quality Level monitored even
when the test is not started.
QL Mismatch Monitoring check box when selected (default) enables
the Quality Level mismatch monitoring. The quality level characterizes
the clock quality in terms of network synchronization.
Expected QL available when the QL Mismatch Monitoring check box
is selected, allows the selection of the Expected Quality Level value.
See page 519 for more information.
Pass/Fail Verdict check box when selected (default) enables the use
of the pass/fail verdict. The global pass/fail verdict is based on the
following criteria: ESMC Rate Threshold (when enabled), QL
Mismatch Monitoring (when enabled), ESMC Loss, or Link Down.
ESMC Rate Threshold check box when selected (default) enables the
ESMC rate threshold monitoring which will declare a Fail verdict when
the ESMC frame rate is outside the range of 0.8 to 10.2 frames/s.
