The DS3 AIS is framed with 'stuck stuffing.'  This implies
that it has a valid M-subframe alignments bits, M-frame
alignment bits, and P bits.  The information bits are set
to a 1010... sequence, starting with a one (1) after each
M-subframe alignment bit, M-frame alignment bit, X bit, P
bit, and C bit.  The C bits are all set to zero giving
what is called 'stuck stuffing.'  The X bits are set to
one.  The DS3 AIS defect is declared after DS3 AIS is
present in contiguous M-frames for a time equal to or
greater than T, where 0.2 ms <= T <= 100 ms.
The DS3 AIS defect is terminated after AIS is absent in
contiguous M-frames for a time equal to or greater than T.
              
The E3 binary content of the AIS is nominally a continuous
stream of ones.  AIS detection and the application of
consequent actions, should be completed within a time
limit of 1 ms.
