Field Description
Loss of Frame Count:
(display field)
A loss of frame occurs when either Network equipment or the DTE senses
errors in the framing pattern. Depending upon the equipment, this occurs
when any 2 of 4, 2 of 5, or 3 of 5 consecutive terminal framing bits received
contain bit errors in the framing pattern.
Time in Interval:
(display field)
A timer that tracks the number of seconds (0-900) since the start of the current
15-minute interval.
# Valid Intervals:
(display field)
A counter that tracks the total number of 15-minute intervals in a 24 hour
period (up to 96).
ESF Status: (display field) This field defines the status of the T1/E1 line. The status is defined by an 8-digit
number that is described below:
Example: F00000L0
Digit #1 - “F” or “0” where “F” indicates Failed Signal State (FSS) if “U” or “L”
is true.
Digit #2 - “U” or “0” where “U” indicates an unavailable signal state.
Digit #3 through #6 and #8 are always “0.”
Digit #7 - “L” or “0” where “L” indicates that the T1 line is in loop.
Re-initialize T1/E1 Framer
The Re-initialize function is used to reset the T1/E1 link framer to its default values.
It is used to rewrite values for the framer if you suspect that a configuration change
didn’t take or odd problems are occurring on the status displays. This function will
only reset the T1/E1 link framer, not the entire module.
Re-initializing the framer will cause data to be momentarily interrupted for the
selected link.
