• Note the input level of the channel. If the reading is more positive than -4 dBm, apply attenuation (negative gain) in the amount that this reading is above -4 dBm.

Normally, this will require the Input Level Gain to be set between -2 and -4 dBm depending on cabling loss. (Note: If the Input Gain is currently set for 0 and the Input Level is below -10 dBm, then the FXS channel should be evaluated for a problem.)

To adjust the input level for the No.1 FXS channel, use Adjust the Input Level Gain and Output Level Attenuation. After the input level gain adjustment is completed, record the setting used to bring the input level to -4 dBm.You will need it to set the other FXS channels.
