SbMaxEpdCi(7:0)
TrafClassMax
(7:0)
Maximum Traffic Class Fill Threshold (determines the maximum
number of cells in all queues associated with this traffic class). The
threshold is defined with a granularity of 256:
Threshold = TrafClassMax(7:0) * 256 Cells
SbMaxEpdCi
(7:0)
Combined Threshold of the Maximum Number of Buffered
Cells in the Scheduler; that is, all cells which are in the traffic
classes (= cells in the corresponding queues) of the Scheduler) for
the following cases:
a) If EPDen=0 and ABRen=0
⇒ Maximum Scheduler fill threshold for CLP=’0/1’ cells
b) If EPDen=1 and ABRen=0
⇒ EPD Scheduler threshold
c) If ABRen=1
⇒ CI Scheduler threshold for ABR connections
(Set CI-Bit (Congestion Indication) in the RM cells)
The threshold is defined with a granularity of 256:
Threshold = SbMaxEpdCi(7:0) * 256 Cells
