• 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 
Temperature 
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  • Server function for automatic IP assignment 
Web GUI  • Remote and local user browser support through Web Browser 
SNMP Agent  • NMS report via SNMPv2 Trap 
LED Display 
• LED displays power and operation status on front side of repeater system. 
• DL input and output signal level is verified by LED bar. 
Report No. : HCT-R07-013     13/33
