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 non-cooled power level 1 part (or non-cooled power level 2 part already enabled at power level 2 for TX_Fault recovery) is fully operational.

5)From falling edge of stop bit enabling power level 2 until non-cooled module is fully operational.

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.
