Field

0
I, M
Average rate. The average rate parameter is set in cells. "I" cells are
transmitted per "M" cell-times (I/M).
Used by
μ
PD98405 to store temporary parameter.
Peak cell rate. Minimum time difference in transmission between two
successive cells in channel linked to shaper. Specified in cells.
Credit. These bits specify the maximum number of credits that can be
accumulated by a shaper.
The I, M, P, and C parameters determine the
maximum number of cells that can be transmitted continuously at the
peak rate (maximum burst size).
Used by
μ
PD98405 to store temporary parameter.

Priority. Host sets priorities of this shaper. '00000' is highest, and '11111' is
lowest.
Aggregate mode. Sets the cell output mode.
0: Normal mode. The rate setting is applied in VC units.
1: Aggregate mode. The rate setting is applied in shaper units.
Scan flag. Used by
μ
PD98405 to manage status of shaper. Do not change
value of this field.
Round robin flag. Used by
μ
PD98405 to manage status of shaper. Do not
change value of this field.
Active flag. Used by
μ
PD98405 to manage status of shaper.
1: Shaper is active.
0: Shaper is inactive.
This bit is set to 1 by host only when unassigned cell generator function is
used.
Enable. Set to '1' by host when this shaper is used.
1: Enables shaper.
0: Disables shaper.
