AGC Mode

AGC (Auto Gain Control) adjusts the variable gain of the repeater to ensure a

constant specified output power of 20 dBm. The functionality of the AGC feature

is assured under the condition that the input BTS signal is within the specified

AGC range (-60 to -35 dBm => assuming AGC Level is set to 20 dBm) and that

sufficient isolation exists between antennas (≥ 93 dB). By default, the

AGC ON

box is checked. To manually change the gains in both the links,

AGC ON

must

be unchecked.

AGC ON

is checked and

Uplink Tracking ON

is unchecked, the user can specify

the AGC level in the downlink and in the uplink respectively @ 0.5 dB step (0 to

20 dBm). By default, the AGC Level is set to 20 dBm in each link.

Downlink/Uplink HPA Mode

The HPA mode enables the user to turn the HPA on or off. If the HPA is turned

off on either link, the Epoch-M1C will not operate properly. Both HPAs needs to

be turned on for the RF portion of the repeater to work in both directions

(downlink and uplink). By default, the

Downlink/Uplink HPA ON

boxes are

checked.

Either or both HPAs can be turned off for troubleshooting purposes during an

installation process.
