OAMTHRU(5:0)
OAMTHRU(5:0)
Threshold for forced OAM cell insertion in upstream direction. If the
upstream 32-cell buffer is filled beyond this level OAM cells are inserted
with lower priority than user cells. Recommended value 30 (1E_H).
0
OAM cell insertion upstream only possible if no cell from
UTOPIA is received.
1..31
Cell insertion has higher priority until filling level of
upstream 32-cell buffer reaches this threshold.
>31
OAM cells are always inserted with higher priority (in case
of 32-cell buffer overflow backpressure to PHY).
