This “Read/Write” bit-field permits the user to enable
or disable the “DS2 Far-End Receive Failure” Inter-
rupt.
Setting this bit-field to “1” enables this interrupt. Con-
versely, setting this bit-field to “0” disables this inter-
rupt.
Bit 2 - DS2 RED Alarm Interrupt Enable
This “Read/Write” bit-field permits the user to enable
or disable the “DS2 RED Alarm” Interrupt.
Setting this bit-field to “1” enables this interrupt. Con-
versely, setting this bit-field to “0” disables this inter-
rupt.
Bit 1 - DS2 AIS Interrupt Enable
This “Read/Write” bit-field permits the user to enable
or disable the “DS2 AIS” Interrupt.
Setting this bit-field to “1” enables this interrupt. Con-
versely, setting this bit-field to “0” disables this inter-
rupt.
Bit 0 - DS2 RESV Interrupt Enable.

Bit 5 - DS2 COFA (Change of Framing Alignment)
Status
This “Read-Only” bit-field reflects the current “COFA”
status of DS2 Channel # 7.
This bit-field will be set to “0” is there is no “Change of
Framing Alignment” in DS2 Channel # 7. Converse-
ly, this bit-field will be set to “1” is there is a “Change
of Framing Alignment” in DS2 Channel # 7.
Bit 4 - DS2 OOF (Out-of-Frame) Status
This “Read-Only” bit-field reflects the current “OOF”
status of DS2 Channel # 7.
This bit-field will be set to “0” if DS2 Channel # 7 is
currently in the “In-Frame” condition. Conversely,
this bit-field will be set to “1” if DS2 Channel # 7 is
currently declaring an “Out-of-Frame” condtion.
Bit 3 - DS2 FERF (Far-End Receive Failure) Status
his “Read-Only” bit-field reflects the current “FERF”
status of DS2 Channel # 7.
This bit-field will be set to “0” if DS2 Channel # 7 is
currently not declaring the “FERF” condition. Con-
versely, this bit-field will be set to “1” if DS2 Channel #
1 is currently declaring a “FERF” condtion.
Bit 2 - DS2 RED Alarm Status
This “Read-Only” bit-field reflects the current “RED
Alarm” status of DS2 Channel # 7.
This bit-field will be set to “0” if DS2 Channel # 7 is
not currently declaring a “RED Alarm” condition.
Conversely, this bit-field will be set to “1” if DS2 Chan-
nel # 7 is currently declaring a “RED Alarm” condition.
Bit 1 - DS2 AIS (Alarm Indication Signal) Status
This “Read-Only” bit-field reflects the current “AIS”
status of DS2 Channel # 1.
