OOFI, AISI, FERFI, REDI:

The OOFI, AISI, FERFI and REDI bits are interrupt status indicators. A

change of state on the corresponding DS2 FRMR status causes the

corresponding interrupt status bit to be set to logic 1.

RESI:

The RESI bit is an interrupt status indicator. A change in the debounced

value of the reserved bit in Set II when in G.747 mode causes this bit to be

set to logic 1. The debounced value of the reserved bit only changes when

the reserved bit is the same for two consecutive frames. This bit has no effect

in DS2 mode.

COFAI:

The COFAI bit is an interrupt status indicator. As per TR-TSY-000820, the

Change of Frame Alignment (COFA) interrupt is only asserted if a frame

search results in a frame alignment which is different from the prior frame

alignment.

The interrupt status bits are cleared when the DS2 FRMR Interrupt Status
