Long Haul -36dB
：
Equalizer detects the input wave and compensates 36dB at most to adjust
input E1 signal, and this function is used for cable loss (frequency), but not flat
loss (resistive)
；
Long Haul -43dB
：
Equalizer detects the input wave and compensates 43dB at most to adjust
input E1 signal, and this function is used for cable loss (frequency), but not flat
loss (resistive)
；
Short Haul -15dB
：
Equalizer detects the input wave and compensates 15dB at most to adjust
input E1 signal, and this function is used for cable loss (frequency), but not flat
loss (resistive)
；
Gain Mode
：
Equalizer detects the input wave and compensates 29dB at most to adjust
input E1 signal, and this function is used for flat loss (resistive), cable loss
(frequency).
