SBMax(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 1024:
Threshold = TrafClassMax(7:0) * 1024 Cells
SBMax(7:0)
Combined Threshold of the Maximum Number of Buffered
Cells in the Scheduler Block; that is, all cells which are in the traffic
classes (= cells in the corresponding queues) of the Scheduler
Block for the following cases:
a) If EPDen=0 and ABRen=0
Þ Maximum Scheduler Block fill threshold for CLP=’0/1’ cells
b) If EPDen=1 and ABRen=0
Þ EPD Scheduler Block threshold
c) If ABRen=1
Þ CI Scheduler Block threshold for ABR connections
(Set CI-Bit (Congestion Indication) in the RM cells)
The threshold is defined with a granularity of 1024:
Threshold = SBMax(7:0) * 1024 Cells
