This register is used to identify and acknowledge remote failure indication
interrupts for the tributaries TU #3 in TUG2 #1 TO TUG2 #7.
RFI1I-RFI7I:
The RFI1I to RFI7I bits identify the source of remote failure indication
interrupts. In TU3 mode, these bits are unused and will return a logic 0 when
read. When the corresponding TUG2 tributary group is configured for TU2
(VT6) or VT3 mode, the associated RFIxI bit is unused and will return a logic
0 when read. When operational, the RFI1I to RFI7I bits report and
acknowledge RFI interrupt of TU #3 in TUG2 #1 to TUG2 #7, respectively.
Interrupts are generated when the received RFI state changes. An RFIxI bit is
set high when a change of RFI state on the associated tributary (TU #3 in
TUG2 #x) occurs and are cleared immediately following a read of this register,
which also acknowledges and clears the interrupt. RFIxI remains valid when
interrupts are not enabled (RFIE set low) and may be polled to detect change
of remote failure indication events.
