Downlink Gain/Uplink Gain: Allows the UL gain to be adjusted manually when ALC is OFF

DL Output ALC Level: Prevents the output power from exceeding the specified value

DL Output ALC Offset: When the incoming signal level increases, the system will not adjust the attenuation

levels until the delta reaches the level specified

DL /UL Gain Balance ON: Allows the user to enable or disable the gain balance. When gain balance is enabled,

the delta value between the downlink and uplink gains remain constant

5.3.5 ICS Control

DL ILC Level: Allows the user to specify the interference level control. The measured isolation value + ILC Level

will provide you with the MAX gain level. When the ILC Level + User Set Gain Level is larger than the measured

isolation value, ILC will adjust the gains levels to match the measure isolation value.

Downlink Signal Low: Allows the user to specify how low the signal can be before triggering a "Downlink

Signal Low" soft-fail alarm

Downlink Signal Not Detected: Allows the user to specify how low the signal can be before triggering a

"Downlink Signal Not Detected" soft-fail alarm

Downlink RF Power: Allows the user to set a maximum deviation value for the downlink RF power

For example, if the input signal is -50 dBm and the gain is set to 60 dB, the expected output power should

be 10 dBm. If the Downlink RF Power alarm value is set to 6dB, then if the output power is below 4 dBm,

then this will trigger a soft-fail alarm
