This set of registers reports the alarm status of TU #4 in TUG2 #1 to TUG2 #7.
These registers have no effect in TU3 mode. When the corresponding TUG2
tributary group is configured to TU2 (VT6), VT3 or TU12 (VT2) mode, the
associated register in this set has no effect.
RELAYAIS:
The RELAYAIS bit controls the number of consecutive AIS_ind indications
required to enter the AIS state for tributary TU #4 in the corresponding TUG2.
When RELAYAIS is set high, AIS is declared upon receipt of a single AIS_ind
indication. When RELAYAIS is set low, AIS is declared after 3 consecutive
AIS_ind indications.
AISV:
The AISV bit indicates the tributary path AIS status of tributary TU #4 in the
corresponding TUG2.
PEE:
The PEE bit enables pointer event interrupts for tributary TU #4 in the
corresponding TUG2. When PEE is set high, an interrupt is generated upon
detection of FIFO underflows and overflows, upon detection of incoming
pointer justification events when the MONIS bit is set high and upon detection
