O
CMOS
Receive SONET POH Processor Block - Path Overhead Output Port
- Frame Boundary Indicator:
These output pins, along with the RxPOH_n, RxPOHClk_n and
RxPOHValid_n output pins function as the Receive SONET POH Pro-
cessor Block - Path Overhead Output Port.
These output pins will pulse "High" coincident with the very first POH
byte (J1), of a given STS-1 frame, is being output via the corresponding
RxPOH_n output pin.

CMOS
Receive SONET POH Processor Block - Path Overhead Output Port
- Valid POH Data Indicator:
These output pins, along with RxPOH_n, RxPOHClk_n and
RxPOHFrame_n function as the Receive SONET POH Processor block
- Path Overhead Output port.
These output pins will toggle "High" coincident with when valid POH data
is being output via the RxPOH_n output pins. This output is updated
upon the falling edge of RxPOHClk_n. Hence, external circuitry should
sample these signals upon rising edge of RxPOHClk_n.
AD11
LOF
O
CMOS
Receive STS-3 LOF (Loss of Frame) Indicator:
This output pin indicates whether or not the Receive STS-3 TOH Proces-
sor block (within the device) is currently declaring the LOF defect condi-
tion as described below.
"Low" - Indicates that the Receive STS-3 TOH Processor block is NOT
currently declaring the LOF defect condition.
"High" - Indicates that the Receive STS-3 TOH Processor block is cur-
rently declaring the LOF defect condition.
AF9
SEF
O
CMOS
Receive STS-3 SEF (Severed Errored Frame) Indicator:
This output pin indicates whether or not the Receive STS-3 TOH Proces-
sor block (within the device) is currently declaring the SEF defect condi-
tion as described below.
"Low" - Indicates that the Receive STS-3 TOH Processor block is NOT
currently declaring the SEF defect condition.
"High" - Indicates that the Receive STS-3 TOH Processor block is cur-
rently declaring the SEF defect condition.
AG7
LOS
O
CMOS
Receive STS-3 LOS (Loss of Signal) Defect Declared Indicator:
This output pin indicates whether or not the Receive STS-3 TOH Proces-
sor block (within the device) is currently declaring the LOS defect condi-
tion as described below.
"Low" - Indicates that the Receive STS-3 TOH Processor block is NOT
currently declaring the LOS defect condition.
"High" - Indicates that the Receive STS-3 TOH Processor block is cur-
rently declaring the LOS defect condition.
