	Parameter			Symbol	Min.		Max.	Unit		Note
TX_DISABLE Assert time				t_off		10		µsec	1
TX_DISABLE Negate time				t_on			2	msec		2
Time	to	initialize	2-wire	t_2w_start_up		300		msec	3
interfase
Time to initialize				t_start_up			300	msec		4
Time	to	initialize	cooled	t_start_up_cooled		90		sec	4
module
Time to Power Up to Level 2				t_power_level2			300	msec		5
Time to Power Down from				T_power_down		300		msec	6
Level 2
TX_Fault assert				TX_Fault_on			1	msec		7
TX_Fault		assert for	cooled	TX_Fault_on		50		msec	7
module
TX_Fault Reset				t_reset	10			µsec		8
Module Reset				t_module_reset			TBD	msec		TBD
RS0, RS1 rate select timing				t_RS0_FC,			500	µsec		9
for FC				RS1_FC
RS0,	RS1	rate select	timing	t_RS0, t_RS1		10		msec	9
non FC
RX_LOS assert delay				t_los_on			100	µsec		10
RX_LOS negate delay				t_los_off		100		µsec	11

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.
