This object is used for injecting continuous errors into transmitted BERT pattern. The errors are inserted in a BERT pattern sent, in order to do sanity check on receive interface in the event that no bit errors are detected. Injecting errors allows users to stress communication links and to check the functionality of error monitoring equipment along the path. Once set to send continuous errors, errors will be inserted at the configured rate until set to errorInsertionDisabled(1). The possible values are : errorInsertionDisabled(1) : no bit errors are inserted. oneInTen(2) : insert bit errors at the rate of 1 bit error per 10 bits (10^-1) transmitted. oneInTenPowerTwo(3) : insert bit errors at the rate of 1 bit error per 100 bits (10^-2) transmitted. oneInTenPowerThree(4): insert bit errors at the rate of 1 bit error per 1000 bits (10^-3) transmitted. oneInTenPowerFour(5): insert bit errors at the rate of 1 bit error per 10000 (10^-4) bits transmitted. oneInTenPowerFive(6): insert bit errors at the rate of 1 bit error per 100000 bits (10^-5) transmitted. oneInTenPowerSix(7) : insert bit errors at the rate of 1 bit error per 1000000 bits (10^-6) transmitted. oneInTenPowerSeven(8): insert bit errors at the rate of 1 bit error per 10,000,000 (10^-7)bits transmitted.
