SATURN USER NETWORK INTERFACE FOR 2488 MBIT/S
to be considered valid. When JUST3EN is set to logic 1, the previous NDF_ENABLE,
INC_IND or DEC_IND indication must be more than 3 frames ago or the present
NDF_ENABLE, INC_IND or DEC_IND indication is considered an INV_POINT indication.
When JUST3EN is set to logic 0, NDF_ENABLE, INC_IND or DEC_IND indication can be
every frame.
This bit is only valid for RHPP STS-1/STM0 #1.
RELAYPAIS:
The relay path AIS (RELAYPAIS) bit selects the condition to enter the path AIS state in the
pointer interpreter state machine. When RELAYPAIS is set to logic 1, the path AIS state is
entered with 1 X AIS_ind indication. When RELAYPAIS is set to logic 0, the path AIS state is
entered with 3 X AIS_ind indications. This configuration bit also affects the concatenation
pointer interpreter state machine.
This bit is only valid for RHPP STS-1/STM0 #1.
INVCNT:
The invalid counter (INVCNT) bit selects the behavior of the consecutive INV_POINT event
counter in the pointer interpreter state machine. When INVCNT is set to logic 1, the
consecutive INV_POINT event counter is reset by 3 X NEW_POINT indications. When
INVCNT is set to logic 0, the counter is not reset by 3 X NEW_POINT indications.
This bit is only valid for RHPP STS-1/STM0 #1.
NDFCNT:
The new data flag counter (NDFCNT) bit selects the behavior of the consecutive
NDF_ENABLE event counter in the pointer interpreter state machine. When NDFCNT is set
to logic 1, the NDF_ENABLE definition is enabled NDF + ss. When NDFCNT is set to logic 0,
the NDF_ENABLE definition is enabled NDF + ss + offset value in the range 0 to 782 (764 in
TU-3 mode). This configuration bit only changes the NDF_ENABLE definition for the
consecutive NDF_ENABLE even counter to count towards LOP-P defect when the pointer is
out of range, this configuration bit does not change the NDF_ENABLE definition for pointer
justification.
This bit is only valid for RHPP STS-1/STM0 #1.
