Bit 4 - COFA (Change of Frame Alignment) Inter-
rupt Enable
This Read/Write bit-field allows the user to enable or
disable the Change of Frame Alignment interrupt.
Setting this bit-field to "1" enables this interrupt. Set-
ting this bit-field to "0" disables this interrupt.
Bit 3 - OOF (Change in OOF Condition) Interrupt
Enable
This Read/Write bit field allows the user to enable or
disable the Change in Out-of-Frame (OOF) status in-
terrupt. Setting this bit-field to "1" enables this inter-
rupt. Setting this bit-field to "0" disables this interrupt.
NOTE: For more information on the OOF Condition, please
see Section 4.3.2.2.
Bit 2 - LOF (Change in LOF Condition) Interrupt
Enable
This Read/Write bit-field allows the user to enable or
disable the Change in Loss-of-Frame (LOF) status in-
terrupt. Setting this bit-field to "1" enables this inter-
rupt. Setting this bit-field to "0" disables this interrupt.
NOTE: For more information on the LOF Condition, please
see Section 4.3.2.2.
Bit 1 - LOS (Change in LOS Condition) Interrupt
Enable
This Read/Write bit-field allows the user to enable or
disable the Change in LOS condition interrupt. Set-
ting this bit-field to "1" enables this interrupt. Setting
this bit-field to "0" disables this interrupt.
NOTE: For more information on the LOS Condition, please
see Section 4.3.2.7.
Bit 0 - AIS (Change in AIS Condition) Interrupt En-
able
This Read/Write bit-field allows the user to enable or
disable the Change in AIS condition interrupt. Setting
this bit-field to "1" enables this interrupt. Setting this
bit-field to "0" disables this interrupt.
NOTE: For more information on the AIS Condition, please
see Section 4.3.2.8
2.3.4.4
Receive E3 Interrupt Enable Register -
2 (E3, ITU-T G.751)
Bit 3 - FERF (Far-End Receive Failure) Interrupt
Enable
This Read/Write bit-field allows the user to enable or
disable the Change in FERF Condition interrupt. Set-
ting this bit-field to "1" enables this interrupt. Setting
this bit-field to "0" disables this interrupt.
NOTE: For more information on the Change in FERF Condi-
tion interrupt, please see Section 4.3.6.1.6.
Bit 2 - BIP-4 Error Interrupt Enable
This Read/Write bit-field allows the user to enable or
disable the BIP-4 Error interrupt. Setting this bit-field
to "1" enables this interrupt. Setting this bit-field to
"0" disables this interrupt.
NOTE: For more information on this interrupt, please see
Section 4.3.6.1.7.
Bit 1 - Framing Error Interrupt Enable
This Read/Write bit-field allows the user to enable or
disable the Framing Error interrupt. Setting this bit-
