= 0: receive equalizer off (short haul receiver)
= 1: receive equalizer on (long haul receiver)
Select fix gain or LOS level detect threshold.
Note that this bit is effective only when long haul operation mode is selected (EQ_ON=1).
= 0: the receiver operates in adaptive gain mode, in which the maximum receive sensitivity is up to 43 dB for E1
and 36 dB for T1.
= 1: fixed gain mode. The receive sensitivity is fixed on the value selected by LOS[4:0].
