Receive section alarm (RSALM) indication: RSALM is asserted when a OOF, LOF, LOS. AIS-L,
RDI-L, APSBF, TIU-S, TIM-S, SDBER or SFBER defect is detected in the receive data stream.
Configuration registers allow the user to remove any defect from the previous enumeration.
Receive line AIS insertion (RLAISINS) indication: RLAISINS is asserted when a OOF, LOF, LOS.
AIS-L, RDI-L, APSBF, TIU-S, TIM-S, SDBER or SFBER defect is detected in the receive data
stream. Configuration register allow the user to remove any defect from the previous
enumeration.
Transmit line RDI insertion (TLRDIINS) indication: TLRDIINS is asserted when a OOF, LOF, LOS.
AIS-L, RDI-L, APSBF, TIU-S, TIM-S, SDBER or SFBER defect is detected in the receive data
stream. Configuration register allow the user to remove any defect from the previous
enumeration.
Receive path alarm (RPALM) indication: RPALM is asserted when a RSALM, MSRSALM, AIS-P,
LOP-P, PLU-P. PLM-P, UNEQ-P, PDI-P, RDI-P, ERDI-P, TIU-P or TIM-P defect is detected in the
receive data stream. Configuration registers allow the user to remove any defect from the
previous enumeration.
Receive path alarm insertion (RPAISINS) indication: RPAISINS is asserted when a RLAISINS,
MSRLAISINS, AIS-P, LOP-P, PLU-P. PLM-P, UNEQ-P, PDI-P, RDI-P, ERDI-P, TIU-P or TIM-P
defect is detected in the receive data stream. Configuration registers allow the user to remove
any defect from the previous enumeration.
Transmit path ERDI insertion (TPERDIINS[2:0]) indication: TPERDIINS[2:0] is updated when a
PLU-P, PLM-P, TIU-P, TIM-P, UNEQ-P, LOP-P or a AIS-P defect is detected in the receive data
stream. Configuration register allow the user to remove any defect from the previous
enumeration.
10.20 SONET/SDH Inband Error Report Processor (SIRP)
The SIRP block is used for error reporting from a remote APS protect mate when operating as the
working mate under a failure condition. When in the failure condition, the remote protect mate
performs section, line and path termination and passes the expected P-REI and P-RDI indications
back to the working mate in-band in the G1 byte via its output APS port. The SIRP block
processes remote alarm indications in the SONET/SDH data stream from the Input APS port. The
SIRP in the companion working mate can be configured to extract remote defect indications (RDI)
and remote error indications (REI) from a STS-48c (STM-4c) incoming data stream. Accumulated
remote error indications and remote defect indications are reported to the THPP block. Both RDI
and extended RDI modes are available. The RDI report can be configured to be maintained
asserted for at least 10 frames or 20 frames.
