The RPAISINS indication is defined by Equation 5. The bits from and including PLOPTREN to
PTIMEN are register configuration bits that individually enable or disable each defect. The bits
exist for each path. The RPAISINS is used to insert P-AIS on the receive SONET/SDH stream.
PAIS is inserted by inserting an all-ones pattern on the H1-H2 and the SPE bytes. Optionally, it
can be inserted on the transport overhead bytes.
Equation 5:

The Path ERDI[2:0] insertion indication (PERDIINS) is defined in Table 41. A RDIEN bit
exists for each path. P-ERDI alarms are used to generate the receive in-band P-RDI alarm. They
are also used to return P-RDI to the far-end device.

The Received Path detects BIP-8 error. The BIP error count is fed back to the transmit side to be
returned as REI-P to the far-end device.
