H
H
Threshold for forced OAM cell insertion in downstream direction. If a
queue of the downstream shared buffer is filled beyond this level OAM
cells destined to the respective PHY are not inserted.
0
1...95
>95
Queue backpressure level in downstream direction. If a queue exceeds
this threshold the downstream receive UTOPIA interface does not
accept any more cell:
0
1...95
>95
(Recommended value is 65.)
H
H
No cell insertion downstream possible.
Cell insertion is possible until queue filling level reaches
threshold.
Cell insertion downstream only limited by buffer overflow
condition.
Always backpressure to downstream receive UTOPIA
interface for all ports.
Backpressure to the respective PHY of the downstream
receive UTOPIA interface if queue filling level reaches
threshold.
Queue specific backpressure disabled, backpressure
controlled by shared buffer overflow only.
