Register 0x00A, 0x10A, 0x20A, 0x30A, 0x40A, 0x50A, 0x60A, 0x70A:
This register, along with Channel Auto Path RDI controls the auto assertion of enhanced path
RDI (G1 bit 5, 6 and 7) in the TPOP for the entire SONET/SDH stream. For more details refer
to the Operation Section of this document.

NOLOPCONEPRDI:
TIMEPRDI:
Channel Auto Enhanced Path RDI Control
When set high, the TIMEPRDI bit enables enhanced path RDI assertion when path trace
message mismatch (TIM) events are detected in the receive stream. When TIMEPRDI is
set high and TIM occurs, bit 6 of the G1 byte is set high while bit 7 of the G1 byte is set
low.
When TIMEPRDI is set low, trace identifier mismatch events have no effect on path RDI.
In addition, this bit has no effect when EPRDI_EN is set low.
When set high, the TIUEPRDI bit enables enhanced path RDI assertion when path trace
message unstable events are detected in the receive stream. When TIUEPRDI is set high
and path trace message unstable occurs, bit 6 of the G1 byte is set high while bit 7 of the G1
byte is set low.
When TIUEPRDI is set low, trace identifier unstable events have no effect on path RDI. In
addition, this bit has no effect when EPRDI_EN is set low.
When set high, the NOLOPCONEPRDI bit disables enhanced path RDI assertion when loss
of pointer concatenation (LOPCON) events are detected in the receive stream. When
NOLOPCONEPRDI is set high and LOPCON occurs, bit 6 of the G1 byte is set low while
bit 7 of the G1 byte is set high. NOLOPCONEPRDI has precedence over PSLMEPRDI ,
TIUEPRDI, TIMEPRDI and UNEQEPRDI.
