This object indicates upstream ETH frame error ratio in current 15 minutes.
The value of this object indicates the exponente of the exponential expression of the upstream ETH frame error ratio.
For example, if the upstream ETH frame bit error ratio is calculated to be (0.0012), the exponential expression is 1.2E-3.
The multiplicando (1.2) is ignored, and the value of this object is (3).
The value (-1) indicates that the query fails or no information is detected.
The value (0xFFFFFFE) indicates that the bit error ratio is (0).
The value (0) indicates that the bit error ratio is (1).
