This register and the S/UNI-QUAD Channel Auto Path RDI Control register controls the auto assertion of enhanced path RDI (G1 bits 5,6,7) in the local TPOP. Since the S/UNI-QUAD provides a STS-3c (STM-1) mapping, this register with its companion register controls auto enhanced path RDI assertion on the entire transmit stream.

NOLOPCONEPRDI:

When set high, the NOLOPCONEPRDI bit disables enhanced path RDI assertion when loss of pointer concatenation (LOPCON) events are detected in the receive stream. If enabled, when the event occurs, bit 6 of the G1 byte is set low while bit 7 of the G1 byte is set high. NOLOPCONEPRDI has precedence over PSLMERDI and UNEQERDI.

When NOLOPCONEPRDI is set low, reporting of enhanced RDI is according to PSLMERDI and UNEQERDI and the associated alarm states.

NOLOPEPRDI:

When set high, the NOLOPEPRDI bit disables enhanced path RDI assertion when loss of pointer (LOP) events are detected in the receive stream. If enabled, when the event occurs, bit 6 of the G1 byte is set low while bit 7 of the G1 byte is set high. NOLOPEPRDI has precedence over PSLMERDI and

UNEQERDI.

When NOLOPEPRDI is set low, reporting of enhanced RDI is according to PSLMERDI and UNEQERDI and the associated alarm states.

PSLMEPRDI:

When set high, the PSLMEPRDI bit enables enhanced path RDI assertion when path signal label mismatch (PSLM) events are detected in the receive
