4. Decrease the DL “USER ATT(①)” to 30dB(Minimum gain) and verify that antenna is
connected at antenna port of SRU properly.
5. Press the “HPA On/Off(②)” button to turn HPA on
6. Monitor the output power level from “ OUT PWR(③)” parameter and tune up “USR ATT(①)”
to set the proper output power level of SRU.
2.6.2 Up Link power setting
1. Use the “ATT(④)” to control Uplink gain.
2. Uplink gain is very important parameter because uplink is connected to RF source of BTS. If
you have wrong uplink gain set BTS receiver sensitivity may be degraded by SRU uplink gain.
3. Try to minimize uplink gain with mobile Tx power.
2.7 Configuration and Maintenance
SRU can be configured in three ways via remote internet connection or local serial port connection.
• SNMPv3 interface through the internet
• Web interface through the internet
• Local management interface through the internet, serial connection, and Bluetooth
Master Unit is a remote management system that provides SNMP v3 and Web interface, and maintains
all functions of optical DAS system including configurations, monitoring, and real time alarm reporting.
