Interval Description
LOFC
The loss of frame count for the current interval.
This is a count of the number of times that an
LOF is declared. An LOF is declared when a
continuous out of frame condition persists for
more than 2.5 seconds. The maximum loss of
frame count is 255.
The total loss of frame count for the previous
x
hours, where
x is 24 hours for aggregate
performance and 8 hours for port performance.
StEvnt
(Only valid for
aggregate
performance.)
The status events register records whether one
or more of the following events have occurred
at least once during the interval. The event is
identified by a letter as follows:
R – A Remote Alarm Indication has been
received on the network interface.
L – Loss Of Signal has occurred on the
network interface.
E – The Excessive Error Rate threshold has
been exceeded.
F – A Frame Synchronization Bit Error has
been detected.
V – A Bipolar Violation has been detected.
If none of these events occurred during the
interval, StEvnt=none will be displayed.
N/A
Complete
(Only valid for
far-end port
performance.)
Bad E1 conditions or loopback tests may
prevent far-end port statistics from reaching the
E1 DSU/CSU. This field indicates whether the
15-minute interval contains 900 seconds of
statistics. If one or more seconds of far-end
statistics are missing, this field will display
Complete=No, otherwise it will display
Complete=Yes. This field is only displayed
when Far is selected from the Prt
n screen.
