IDLI:

The IDLI bit indicates that a change of state of the DS3 IDLE signal detector

has occurred. When the IDLI bit is a logic 1, a change in the IDLE detector

state has occurred. When the IDLI bit is logic 0, no change in the IDLE signal

detector state has occurred.

FERFI:

The FERFI bit indicates that a change of state of the FERF indication has

occurred. The FERF indication is visible in the FERFV bit location of the DS3

FRMR Status register and on the RFERF pin. When the FERFI bit is a logic

1, a change in the FERF state has occurred. When the FERFI bit is logic 0,

no change in the FERF state has occurred.

CBITI:

The CBITI bit indicates that a change of state in the C-bit Identification

indication internal to the DS3 FRMR has occurred. When the CBITI bit is a

logic 1, a change in the internal CBIT state has occurred. When the CBITI bit

is logic 0, no change in the CBIT state has occurred.

REDI:

The REDI bit indicates that a change of state of the DS3 RED indication has

occurred. The DS3 RED indication is visible in the REDV bit location of the

DS3 FRMR Status register and on the ROOF/RRED pin when the REDO bit

in the Master Alarm Enable register ( register 06Hex) is set to logic 1. When

the REDI bit is a logic 1, a change in the RED state has occurred. When the

REDI bit is logic 0, no change in the RED state has occurred.

COFAI:

The COFAI bit indicates that a change of frame alignment (i.e. a COFA event)

has occurred. When the COFAI bit is a logic 1, the frame alignment

acquisition circuitry has detected that the new alignment differs from the

previous frame alignment. When the COFAI bit is logic 0, there was no

difference from the current frame alignment and the previous frame

alignment.

The interrupt status bits are cleared when the FRMR Interrupt Status Register is

read.
