Notes:
1)Rising edge of TX_Disable to fall of output signal below 10% of nominal.
2)Falling edge of TX_Disable to rise of output signal above 90% of nominal. This only applies in normal operation, not during start up or fault recovery.
3)From power on or negation of TX_Disable.
4)From power on or TX_Disable negated during power up, or TX_Fault recovery, until 
5)From falling edge of stop bit enabling power level 2 until 
6)From falling edge of stop bit disabling power level 2 until module is within power level 1 requirements.
7)From Occurrence of fault to assertion of TX_Fault.
8)Time TX_Disable must be held High to reset TX_Fault.
9)From assertion till stable output.
10)From Occurrence of loss of signal to assertion of LOS
11)From Occurrence of presence of signal to negation of RX_LOS.
