Rx DS3 Interrupt Enable Register
Bit 7—CP Bit Error Interrupt Enable
This “Read/Write” bit-field is used to enable or disable
the “CP-Bit Error” interrupt. Setting this bit-field to “0”
disables this interrupt. Setting this bit-field to ‘1’
enables this interrupt.
Bit 6—LOS Interrupt Enable
This “Read/Write” bit-field is used to enable or dis-
able the “Change in LOS condition” interrupt. Setting
this bit-field to “1” enables this interrupt. Setting this
bit-field to “0” disables this interrupt. For more informa-
tion on the LOS Condition, please see Sections
6.4.3.2.5 and 7.1.2.3.1.
Bit 5—AIS Interrupt Enable
This “Read/Write” bit-field is used 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. For more information
on the AIS Condition, please see Sections 6.4.2.3
and 7.1.2.3.2.
Bit 4—Idle (Condition) Interrupt Enable
This “Read/Write” bit-field is used to enable or disable
the “Change in Idle condition” interrupt. Setting this
bit-field to “1” enables this interrupt. Setting this bit-
field to “0” disables this interrupt. For more information
on the Idle Condition, please see Section 7.1.2.3.3.
Bit 3—FERF Interrupt Enable
This “Read/Write” bit-field is used to enable or dis-
able the “Change in FERF (Far End Receive Failure)
Status” interrupt. Setting this bit-field to “1” enables
this interrupt. Setting this bit-field to “0” disables this
interrupt. For more information on Far-End Receive
Failures (or Yellow Alarms) please see Section
7.1.2.3.4.
Bit 2—AIC Interrupt Enable
This “Read/Write” bit field allows the user to enable or
disable the “Change in AIC value” interrupt. Setting
this bit-field to “1” enables this interrupt. Setting this
bit-field to “0” disables this interrupt. For more infor-
mation on this interrupt condition, please see Section
7.1.2.9.1.
Bit 1—OOF Interrupt Enable
This “Read/Write” bit field is used to enable or disable
the “Change in Out-of-Frame (OOF) status” interrupt.
Setting this bit-field to “1” enables this interrupt.
Setting this bit-field to “0” disables this interrupt. For
more information on the “OOF’ Condition, please see
Section 7.1.2.2.2.
Bit 0—Parity Error Interrupt Enable
This “Read/Write” bit-field is used to enable or disable
the “P-Bit Error Detection” interrupt. Setting this bit-
field to “1” enables this interrupt. Setting this bit-field
to “0” disables this interrupt. For more information on
the P-Bit Error Checking/Detection, please see
Section 7.1.2.4.1.
