LOSV

LOSV:

The LOSV bit indicates the current state of the loss of signal detector. When

the LOSV bit is a logic 1, a sequence of 175 consecutive zeros was detected

on the dual-rail RPOS and RNEG DS3 inputs. When the LOSV bit is logic 0, a

valid DS3 signal with a ones' density greater than 33% for 175 ± 1 bit periods

was detected on the dual-rail inputs.

OOFV:

The OOFV bit indicates the current state of the DS3 FRMR frame alignment

acquisition circuitry. When the circuitry has lost frame alignment and is

searching for the new alignment, an out of frame is indicated and the OOFV

bit is set to logic 1. When the circuitry has found frame alignment, the OOFV

bit is set to logic 0.

AISV:

The AISV bit indicates the current state of the DS3 AIS signal detector. When

the AISV bit is a logic 1, the DS3 AIS pattern has been received for 2.23ms

(or for 13.5ms when FDET is logic 0). When the AISV bit is logic 0, the DS3

AIS pattern has not been received for either 2.23ms or 13.5ms.

IDLV:

The IDLV bit indicates the current state of the DS3 IDLE signal detector.

When the IDLV bit is a logic 1, the DS3 IDLE pattern has been received for

2.23ms (or for 13.5ms when FDET is logic 0). When the IDLV bit is logic 0, the

DS3 IDLE pattern has not been received for either 2.23ms or 13.5ms.
