4.5.2 Operating Control
• DL and UL Path Control allows the user to toggle on or off the power amplifiers.
• DL and UL Gain is available when AGC mode is off. The user may enter gain values
manually. Manual gain control is an alternative to automatic gain control(AGC). Manual gain
is disabled (grayed out) when AGC mode is on. Gain cannot be controlled manually above
the available gain found on the status page. The system will not allow gain to be increased
such that maximum output power(30dBm) is exceeded.
• Gain Tracking sets UL gain equal to DL gain. The feature helos maintain forward and
reverse link balance. The function control is grayed out when AGC mode is on.
• Automatic Gain Control :
- In contrast to manual gain control, automatic gain control (AGC) sets gain such that the
desired amplifier output level (dBm) is automatically set.
- The user controls gain by adjusting the AGC level. The user may set the level from 0dBm to
30dBm. AGC can be used to control the signal level radiated from the server antenna.
- AGC may also be user to match the repeater to a DAS (distributed antenna system). AGC
level may be restricted by available gain and DL input power.
• UL Gain offset is used in conjuction with AGC to reduce the amount of amplification in the
reverse direction (uplink). In the cases UL offset is set to -2dB.
• Automatic Shutdown (ASD):
- ASD temporarily shuts down the amplifier if the ASD level is exeded. It is not necessary to
turn off ASD. ASD events are stored in the alarm hostory log. Repeated ASD events will
