INTERFACES
low, the generation of AIS on the outgoing data stream is inhibited. The
negation of AIS occurs at tributary multiframe boundaries.
PSLMAIS:
The PSLMAIS bit is an active high AIS insertion enable. When PSLMAIS is
set high, AIS is automatically generated on the outgoing data stream for all
tributaries that are in path signal label mismatch state. When PSLMAIS is set
low, the generation of AIS on the outgoing data stream is inhibited. The
negation of AIS occurs at tributary multiframe boundaries. The generation of
AIS is inhibited when UNEQ is active, regardless of the PSLM state.
UNEQAIS:
The UNEQAIS bit is an active high AIS insertion enable. When UNEQAIS is
set high, AIS is automatically generated on the outgoing data stream for all
tributaries that are unequipped. When UNEQAIS is set low, the generation of
AIS on the outgoing data stream is inhibited. The negation of AIS occurs at
tributary multiframe boundaries.
LOPAIS:
The LOPAIS bit is an active high AIS insertion enable. When LOPAIS is set
high, AIS is automatically generated on the outgoing data stream for all
tributaries that are in loss of pointer state. When LOPAIS is set low, the
generation of AIS on the outgoing data stream is inhibited. The negation of
AIS occurs at tributary multiframe boundaries. This bit is logically OR'ed with
the bit of the same name in STP Incoming Configuration register.
LOMAIS:
The LOMAIS bit is an active high AIS insertion enable. When LOMAIS is set
high, AIS is automatically generated on the outgoing data stream for all
tributaries that are in loss of tributary multiframe state. When LOMAIS is set
low, the generation of AIS on the outgoing data stream is inhibited. LOMAIS
has no effect on TU3 streams.
