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 enable/disable any defect from the
previous enumeration.
In some applications, the receive overhead processor and the transmit overhead processor do not
reside on the same device. The receive defects are returned to the far end through a ring control
port (RCP). The SARC inserts all the section, line and path defects detected in the local receive
data stream into the receive RCP output port. The SARC extracts the APS, line RDI, line REI,
path ERDI and path REI defects to be inserted in the local transmit data stream from the
transmit RCP input port. The RCP port is a low speed asynchronous serial interface operating at
20.736 MHz. The defects carried by the RRCP port is show in table
When the RCP port is enabled, the APS, line RDI, line REI, path ERDI and path REI defect
indications to be inserted in the transmit data stream are extracted from the RCP port. When the
RCP port is disabled, the defect indications to be inserted in the transmit data stream are derived
from the defects detected in the receive data stream.
