The RTOP336 detects tributary payload defect indication (PDI-V) for each incoming tributary
and output to the downstream functional block. The RTOP336 generates tributary path AIS
indication for the outgoing tributaries as a consequential action upon a received AIS, LOP,
LOM, PSLM, PSLU, UNEQ, TIU, or TIM alarm.
The RTOP336 can also be configured to generate the inband error report. This feature allows the
insertion of remote alarm signals (RDI/RFI/ERDI[2:0]/REI) into the V5 byte (G1 byte for TU3
mode) in the outgoing tributaries. Table 13 summarizes the priority encoding for the G1 byte
(TU3 mode) or V5/Z7(K4) bytes (non-TU3 mode) when inband error reporting is enabled by
setting the RTOP336 IBER register bit to a logic 1. The table enumerates the values inserted
into the G1 or V5/Z7(K4) bytes when enhanced remote defect indication is enabled (ERDIEN is
set to a logic 1) and disabled (ERDIEN is set to a logic 0), respectively. Bits marked as “pass”
are not modified.

Notes
1.
2.
In TU3 mode, G1 byte contains RDI/ERDI. In non-TU3 mode, V5/Z7(K4) byte contains RDI/ERDI.
Insertion requires the RTOP336 IBER register bit to be set to logic 1.
