Bwd SECBC
When ‘1’, the accumulating Bwd Severly Errored Cell Block
Combined count had its MSB set. This indicator is not used if
PM Direction is ‘1’.

Fwd/Bwd Lost Fwd PM
Cells
When ‘1’, the Fwd or Bwd Lost Fwd PM Cells count had its
MSB set, depending on the setting of the PM Direction bit.
Because this count may roll over quite frequently, there is a
register bit, Sat_Fast_PM_Counts, which forces this error
count to saturate, and not generate Count Rollover FIFO
entries.
Bwd Lost Bwd PM cells When ‘1’, the Bwd Lost Backward PM Cells count had its MSB
set. This indicator is not used if PM Direction is ‘1’. Because
this count may roll over quite frequently, there is a register bit,
Sat_Fast_PM_Counts, which forces this error count to
saturate, and not generate Count Rollover FIFO entries.

10.17 Cell Routing
Generated reverse flow cells (Backward Reporting PM cells, Loopback cells, and RDI cells) are
routed to the Output Backward OAM Cell Interfaces of the S/UNI-ATLAS-3200. The output
BCIF has a 16 cell FIFO for buffering these cells before they are sent out. Cells generated in the
backward direction may be header translated as if they were being transmitted to the OCIF
depending on the setting of Xlate_To_OBCIF.
Cells received by the S/UNI-ATLAS-3200 on the Input Backward Cell Interface are buffered in a
16 cell FIFO , paced, and inserted into the cell flow stream.
