DESCRIPTION
Transmit FERF/RDI upon Declaration of the LOS defect con-
dition:
This READ/WRITE bit-field permits the user to configure the
Transmit DS3 Framer block to automatically transmit the FERF/
RDI indicator, anytime (and for the duration that) the correspond-
ing (Near-End) Receive DS3 Framer block declares the LOS
defect condition, as described below.
0 - The Transmit DS3 Framer block will NOT automatically trans-
mit the FERF/RDI indicator, whenever (and for the duration that)
the Receive DS3 Framer block declares the LOS defect condi-
tion.
1 - The Transmit DS3 Framer block will automatically transmit
the FERF/RDI indicator whenever (and for the duration that) the
Receive DS3 Framer block declares the LOS defect condition.
Transmit FERF/RDI upon Declaration of the OOF Defect
Condition:
This READ/WRITE bit-field permits the user to configure the
Transmit DS3 Framer block to automatically transmit the FERF/
RDI indicator, anytime (and for the duration that) the correspond-
ing (Near-End) Receive DS3 Framer block declares the OOF
defect condition, as described below.
0 - The Transmit DS3 Framer block will NOT automatically trans-
mit the FERF/RDI indicator, whenever (and for the duration that)
the corresponding (Near-End) Receive DS3 Framer block
declares the OOF defect condition.1 - The Transmit DS3 Framer
block will automatically transmit the FERF/RDI indicator when-
ever (and for the duration that) the Receive DS3 Framer block
declares the OOF defect condition.
Transmit FERF/RDI upon Declaration of the AIS Defect
Condition:
This READ/WRITE bit-field permits the user to configure the
Transmit DS3 Framer block to automatically transmit the FERF/
RDI indicator, anytime (and for the duration that) the correspond-
ing (Near-End) Receive DS3 Framer block declares the AIS
defect condition, as described below.
0 - The Transmit DS3 Framer block will NOT automatically trans-
mit the FERF/RDI indicator, whenever (and for the duration that)
the corresponding (Near-End) Receive DS3 Framer block
declares the AIS defect condition.
1 - The Transmit DS3 Framer block will automatically transmit
the FERF/RDI indicator whenever (and for the duration that) the
Receive DS3 Framer block declares the AIS defect condition.
