Gain
Balance
• Downlink ATT is applied to Uplink during AGC state
• Setting and maintenance of output level
• Additional attenuation to ALC Level
Oscillation
Check
• Isolation Check in initial set up or Reset
• Monitoring Oscillation comparing to minimum/maximum Noise Floor level
• When Oscillation occurred, repeater attempts to stabilize Isolation through Gain control function.
• Shutdown repeater when Oscillation still goes in Minimum Gain
• Automatic Recovery Algorithm conversion after Shutdown status
Spurious
Emission
Alarm
• Noise Floor Observation in case of ±2.25MHz down at the center
• In case of Noise level > –13dBm, Spurious Emission is stabilized automatically
• In case of Oscillation Spurious Emission Alarming in Minimum Gain, repeater will be shutdown
• Automatically Switch to Recovery Algorithm at Shutdown
Band Select • To select either 5MHz/10MHz/15MHz/20MHz
Power
Monitoring
Function
• Monitoring repeater’s output level
DL Input
control
• Monitoring Donor ANT input power of DL
Automatic
Recovery
• When in repeater shutdown, it periodically recovers output power of repeater then monitors
alarming
Security
• Support HTTPS for Web Browser security
• User authentication through User ID and Password
Tempera ture
control
• Monitoring temperature of repeater
• Maximum and minimum set up is possible. Shutdown in over temperature
• Automatic recovery after temperature becomes normal. (Hysteresis 10 degree)
VSWR
Monitoring
• Monitoring VSWR of Donor ANT Port (Every one and half minute)
• Reporting VSWR Alarm and Shutdown when the rate is 3:1
• Automatic Recovery Algorithm conversion after Shutdown status
IP address
report via E-
mail
• When in PPP reconnection, E-mail which includes HTML to connect to newly assigned IP Address,
reports to operator.
DHCP Client • Automatic IP assignment
DHCP • Server function for automatic IP assignment
