DESCRIPTION
Detection of FEBE Event Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the Detection of FEBE Event Interrupt, as indicated
below.
0 - Disables the Detection of FEBE Event Interrupt.
1 - Enables the Detection of FEBE Event Interrupt. In this mode,
the Receive E3 Framer block will generate an interrupt anytime it
detects a FEBE (Far-End Block Error) indicator in the incoming
E3 data-stream.
Change of FERF/RDI Defect Condition Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the Change of FERF/RDI Defect Condition Interrupt, as
indicated below.
0 - Disables the Change in FERF/RDI Defect Condition Interrupt.
1 - Enables the Change in FERF/RDI Defect Condition Interrupt.
In this mode, the Receive E3 Framer block will generate an inter-
rupt, in response to either of the following conditions.
a. Whenever the Receive E3 Framer block declares the
FERF/RDI defect condition.
b. Whenever the Receive E3 Framer block clears the FERF/
RDI defect condition.
Detection of BIP-8 Error Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the Detection of BIP-8 Error Interrupt, as indicated
below.
0 - Disables the Detection of BIP-8 Error Interrupt.
1 - Enables the Detection of BIP-8 Error Interrupt. In this mode,
the Receive E3 Framer block will generate an interrupt anytime it
detects a BIP-8 error in the incoming E3 data-stream.
Detection of Framing Byte Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the Detection of Framing Byte Error Interrupt, as indi-
cated below.
0 - Disables the Detection of Framing Byte Error Interrupt.
1 - Enables the Detection of Framing Byte Error Interrupt. In this
mode, the Receive E3 Framer block will generate an interrupt
anytime it detects a FA1 or FA2 byte error in the incoming E3
data stream.
Received Payload Type Mismatch Interrupt Enable:
This READ/WRITE bit-field permits the user to either enable or
disable the Receive Payload Type Mismatch interrupt, as indi-
cated below.
0 - Disables the Received Payload Type Mismatch Interrupt.
1 - Enables the Received Payload Type Mismatch Interrupt. In
this mode, the Receive E3 Framer block will generate an inter-
rupt anytime it receives a Payload Type value (within the MA
byte) that differs from that written into the RxPLDExp[2:0] bit-
fields.
