The RPAISINS indication is defined by Equation 6. The bits from and including RLAISINSEN
to PTIMEN in the Indirect Register 2H: SARC Path Receive AIS-P Insert Enable Indirect Data
(48 path)
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.

The Path ERDI[2:0] insertion indication (PERDIINS) is defined in Table 23. 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.
