Loss of Signal When testing 1G or 100M optical Ether-
net, indicates the signal has been lost
since starting the test.
Lost Frames A count of lost Acterna test frames. For
example, if the HST detects sequence
numbers: 1, 2, 3, 6, 7, 8, (frames 4 and 5
were not detected), the lost frame count is
incremented by two (frames 4 and 5 are
lost). If the HST then detects sequence
numbers 9, 10, 14, 15, 16 (frames 11, 12,
and 13 are missing), the lost frame count
is incremented by three, resulting in a
total count of five lost frames.
NOTE: If the HST receives errored frames
with errors in the sequence number field,
the Lost Frames count will be incorrect.
OoS Frames A count of each instance where the HST
detects out of sequence Acterna test
frames in the stream. For example, if the
HST detects sequence numbers: 1, 2, 3,
6, 7, 8, (frame 6 is detected immediately
following frame 3), the out of sequence
count is incremented by one, resulting in a
count of one instance of out of sequence
frames. If the HST then detects sequence
numbers 9, 10, 14, 15, 16 (frame 14 is
detected immediately following frame 10),
the out of sequence number is incre-
mented again by one, resulting in a total
count of two instances of out of sequence
frames.
Pause Frames A count of PAUSE frames received from a
remote Ethernet device since starting the
test.
Runts A count of Ethernet frames under the min-
imum 64 byte frame length containing
Frame Check Sequence (FCS) errors.
