The Low Speed Errors-24 hr. screen updates every 15 minutes, displaying
error counts for two time periods: from Midnight the current day to the end
of the last completed 15-minute period (Current View) and from Midnight
the previous day to one second before Midnight the current day (Previous
View).
When you select either view in the View field, the upper portion of the
screen displays Errored Seconds (ES), Errored Seconds Ratio (ESR), Se-
verely Errored Seconds (SES), and Severely Errored Seconds Ratio
(SESR) for all channels. By typing a channel number in the Channel #
field, you can view the CV. LOSS, and AISS error counts for each channel
in the lower portion of the screen. When finished viewing the error counts,
you can either clear both periods for the channel you are viewing or clear
them for all channels.

00:14:59) no Current counts are shown. However, you still can see error
counts during this period by going to the Low Speed Errors-15 min. screen.
