Description: This attribute indicates the maximum value of the txCellFreeListSize and the discard thresholds of the transmit cell free list. The transmit cell free list is the memory used for storing ATM cells to be transmitted by the Lp.

The first value indicates the maximum size of the transmit cell free list. This is derived based upon the connectionPoolCapacity and the txFrameMemoryAllocation under the ARC component.

When the txCellFreeListSize decreases to the second value, the txCellFreeListCongestionState changes from 3 to 2. In congestion state 2, traffic with discard priority (DP) = 3 is discarded. This threshold is set approximately at 25 percent of the first value, the maximum transmit cell free list size.

When the txCellFreeListSize decreases to the third value, the txCellFreeListCongestionState changes from 2 to 1. In congestion state 1, traffic with discard priority (DP) = 2 is discarded. This threshold is set approximately at 20 percent of the first value, the maximum transmit cell free list size.

When the txCellFreeListSize decreases to the fourth value, the txCellFreeListCongestionState changes from 1 to 0. In congestion state 0, traffic with discard priority (DP) = 1 is discarded. This threshold is set approximately at 10 percent of the first value, the maximum transmit cell free list size.
