• Sensitive adds a 10
-6
BER event to the wrap and/or unwrap criteria. A wrap
will occur on occurrence of a standard wrap event and/or a 10
-6
BER event.
Similarly an unwrap will not occur until after completion of an error-free
period that is clear of any standard or 10
-6
BER events.
• The Error-free Timer sets the period of error-free operation needed prior to
initiation of an unwrap. (When a wrap has occurred the timer counts down
towards an unwrap as soon as all wrap conditions are cleared. The count
begins anew should a wrap condition re-occur during the countdown).
Default is 5 minutes (recommended).
• The Delay Ring Unwrap option allows setting of a time of day when an
unwrap will occur providing all wrap conditions have been cleared for a
period not less than that set in the Error-free Timer.
- With this option selected the Wrap and Unwrap criteria default to
Standard.
- The Delay Ring Unwrap has a 1-hour window. If the conditions which
caused the wrap are not cleared by the Error-free Timer during this
window, then Delay Ring Unwrap resets for the same time the
following day.
• The System/Controls screen provides a countdown timer to indicate the time
to go before the ring will unwrap. Applies to both the Error-free Timer and
Delay Ring Unwrap Timer. (Counts down to zero).
