Errored secs
The occurrence of a Loss of Frame or a CRC-6 error in a one-second period is
known as an errored second. This field represents the number of errored seconds
that have occurred.
Failed secs (UAS)
Each second period during the occurrence of a Failed Signal State (ten
consecutive errored seconds) is known as a failed second. This field represents
the number of failed seconds that have occurred.
Severely errored secs A one-second period in which three hundred twenty (320) or more CRC-6 errors
have occurred is known as a severely errored second. This field represents the
number of severely errored seconds that have occurred.
Bursty errored secs
A one-second period in which more than one but less than 320 CRC-6 errors have
occurred is known as a bursty errored second. This field represents the number
of bursty errored seconds that have occurred.
Loss of frame count
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.
