An OOF defect is the occurrence of a particular density
of Framing Error events.
              
For T1 links, an Out of Frame defect is declared when the
receiver detects two or more framing errors within a 3
msec period for ESF signals and 0.75 msec for D4 signals,
or two or more errors out of five or fewer consecutive
framing-bits.
              
For E1 links, an Out Of Frame defect is declared when
three consecutive frame alignment signals have been
received with an error (see G.706 Section 4.1 [17]).
              
Once an Out Of Frame Defect is declared, the framer
starts searching for a correct framing pattern.  The Out
of Frame defect ends when the signal is in frame.
              
In-frame occurs when there are fewer than two frame bit
errors within 3 msec period for ESF signals and 0.75 msec
for D4 signals.
              
For E1 links, in-frame occurs when a) in frame N the
frame alignment signal is correct and b) in frame N+1 the
frame alignment signal is absent (i.e., bit 2 in TS0 is a
one) and c) in frame N+2 the frame alignment signal is
present and correct.
