AGS Algorithm description

Oscillation can be reduced in case that 3dB Attenuation is increased in an excess of Isolation Gap

ATT status value : 0~2.5dB (Shutdown on , DL/UL PAM on, DL Always OSC on)

3dB~30dB (ALC on ,shutdown on , DL/UL PAM on, DL Always OSC on)

Over 30dB (uplink OSC Alarm , DL/UL PAM off )

1. Isolation Check in initial set up or Reset

2. Monitoring Oscillation comparing to minimum/maximum Noise Floor level

3. When Oscillation occurred, repeater attempts to stabilize Isolation through Gain control function

4. Shutdown repeater when Oscillation still occurs in Minimum Gain

5. Automatic Recovery Algorithm conversion after Shutdown status
