This register controls the auto assertion of path AIS on the receive side of the
system interface. AIS forces a loss of cell delineation.
PA I S PA IS :
When set high, the PAISPAIS bit enables path AIS insertion when path AIS
events are detected in the receive stream. When PAISPAIS is set low, path
AIS events will not assert path AIS.
LOPPAIS:
When set high, the LOPPAIS bit enables path AIS insertion when loss of
pointer (LOP) events are detected in the receive stream. When LOPPAIS is
set low, loss of pointer events will not assert path AIS.
LOPCONPAIS:
When set high, the LOPCONPAIS bit enables path AIS insertion when loss of
pointer concatenation (LOPCON) events are detected in the receive stream.
When LOPCONPAIS is set low, loss of pointer concatenation events have will
not assert path AIS.
PAISCONPAIS:
When set high, the PAISCONPAIS bit enables path AIS insertion when Path
AIS concatenation (PAISCON) events are detected in the receive stream.
When PAISCONPAIS is set low, Path AIS concatenation events will not assert
path AIS.
