This attribute specifies the allowable error rate beyond which the
AtmAccess component can be degraded if the error rate persists for
a duration longer than the maximumErrorInterval. The threshold is
expressed as a percentage. It is the ratio of the number of errored
cells in the last interval over the number of cells received in the last
interval. For AAL5, the number of errored cells is converted from
rxFrameDiscard of AtmIf Vcc using the assumption that three ATM
cells are used to carry a 128 byte AAL5 frame. The number of
received cells is specified by rxCell of AtmIf Vcc.
The configurable values are:
0 = the mechanism is completely disabled
1 = 1/(2**1)
2 = 1/(2**2)
3 = 1/(2**3)
:
10 = 1/(2**10)
