UNEQEPRDI
This register along with the Enhanced Path RDI Control register controls the auto assertion of
path RDI (G1 bit 5, 6 and 7) in the TPOP for the entire SONET/SDH stream.
UNEQEPRDI:
When set high, the UNEQEPRDI bit enables enhanced path RDI assertion when the path
signal label in the receive stream indicates unequipped status. When UNEQEPRDI is set
high and the path signal label indicates unequipped, bit 6 of the G1 byte is set high while bit 7
of the G1 byte is set low.
When UNEQEPRDI is set low, path signal label unequipped status has no effect on
enhanced path RDI.
UNEQPRDI:
When set high, the UNEQPRDI bit enables path RDI assertion when the path signal label in
the receive stream indicates unequipped status. When UNEQPRDI is set low, the path signal
label unequipped status has no effect on path RDI.
EPRDI_EN:
The EPRDI_EN bit enables the automatic insertion of enhanced RDI in the local transmitter.
When EPRDI_EN is a logic one, auto insertion is enabled using the event enable bits in this
register. When EPRDI_EN is a logic zero, enhanced path RDI is not automatically inserted in
the transmit stream.
NOPAISCONEPRDI:
When set high, the NOPAISCONEPRDI bit disables enhanced path RDI assertion when path
AIS concatenation (PAISCON) events are detected in the receive stream. When
NOPAISCONEPRDI is set high and PAISCON occurs, bit 6 of the G1 byte is set low while bit
