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
Þ Maximum Scheduler Block fill threshold for CLP=’0/1’ cells
b) If EPDen=1
Þ EPD Scheduler Block threshold
The threshold is defined with a granularity of 1024:
Threshold = SBMax(7:0) * 1024 Cells

AcceptedCells/Packets(23:16)
AcceptedCells/

(31:16)
Count of Accepted Cells or AAL5 Units within this traffic class,
depending on flag SCNT in TCT3.
If SCNT = 0:
This counter is incremented when a user data cell with AAL_
indication=1 is accepted (Packet end indication in AAL5: PTI= xx1).
If SCNT = 1 all accepted cells are counted
Do not Write in normal operation.
Must be reset after Read access.
