The FERFV bit indicates the current state of the FERF indication. When the

FERFV bit is a logic 1, the FRMR detected that the second to last M-frame's

X2=X1=0. When the FERFV bit is logic 0, the second to last M-frame's

X2=X1=1.

CBITV:

The CBITV bit indicates the current state in the C-bit Identification indication.

When the CBITV bit is a logic 1, the first C-bit of M sub-frame 1 has been

observed to be logic 1 for 63 consecutive occasions. When the CBITV bit is

logic 0, the first C-bit of sub-frame 1 has either not been logic 1 for 63

consecutive occasions or, if CBITV was previously logic 1, the first C-bit of

sub-frame 1 has been observed to be logic 0 for 2 or more times within 15

consecutive occasions.

REDV:

The REDV bit indicates the current state of the DS3 RED indication. When

the REDV bit is a logic 1, the DS3 FRMR frame alignment acquisition circuitry

has been out of frame for 2.23ms (or for 13.5ms when FDET is logic 0). When

the REDV bit is logic 0, the frame alignment circuitry has found frame (i.e.

OOFV=0) for 2.23ms ( or 13.5ms if FDET=0).

ACE:

The ACE bit selects the Additional Configuration Register. This register is

located at address 35H, and is only accessible when the ACE bit is set to

logic 1. When ACE is set to logic 0, the Interrupt Enable register is accessible

at address 35H.
