mscLpE3TestBitErrorRate 1.3.6.1.4.1.562.36.2.1.12.6.2.12.1.11

This attribute is not displayed for ATM cards because the physical layer drops all errored frames at the controller interface. For all other card types, this attribute is the calculated bit error rate on the link. Test data are generated and sent in frames of a preset size (frameSize). The Test component will try to estimate the number of bit errors in any errored frame which is identifiable. The statistics will be updated accordingly. A lost frame (may be due to an error on the flag sequence) will be discarded for the bit error rate calculation. The result is presented in the form of xEsyy, where x is the mantissa, syy is the exponent, for example 0E+00, 2E-09. Note that the bitErrorRate is an estimate only. For more reliable test results, the test should be done over a long period. Multiple tests would also improve the confidence level of the test results.
