LOSV

LOSV:

The LOSV bit indicates the current loss of signal defect state. LOSV is a logic

1 when a sequence of 175 zeros is detected on the B3ZS encoded DS3

receive stream. LOSV is a logic 0 when a signal with a ones density greater

than 33% for 175 ± 1 bit periods is detected.

OOFV:

The OOFV bit indicates the current DS3 out of frame defect state. When the

S/UNI-QJET has lost frame alignment and is searching for the new alignment,

OOFV is set to logic 1. When the S/UNI-QJET has found frame alignment,

the OOFV bit is set to logic 0.

AISV:

The AISV bit indicates the alarm indication signal state. When the

S/UNI-QJET detects the AIS maintenance signal, AISV is set to logic 1.

IDLV:

The IDLV bit indicates the IDLE signal state. When the S/UNI-QJET detects

the IDLE maintenance signal, IDLV is set to logic 1.

FERFV:

The FERFV bit indicates the current far end receive failure defect state.

When the S/UNI-QJET detects an M-frame with the X1 and X2 bits both set

to zero, FERFV is set to logic 1. When the S/UNI-QJET detects an M-frame

with the X1 and X2 bits both set to one, FERFV is set to logic 0.
