CommScope ATC200-LITE-USB Instruction Sheet

Figure 2-3. Option 3: Upgrading Actuator Firmware Through SBTs.
2.3 Option 3: Using Smart Bias Tees
In order to connect the portable controller with the installed actuator, Smart Bias Tees (SBTs) can
be used to inject the AISG signal into the RF feeder cable.
At the top of the site, either a top SBT or TMA is used to extract the signal from the RF line. A short
RET jumper cable connects the TOP SBT with the actuator. That top configuration does not need to
be changed for the firmware upgrade if the top SBT or TMA supports AISG mode. See Figure 2-3,
Option 3A.
On the bottom of the site, a bottom SBT is needed. If no bottom SBT is permanently installed, then a
bottom SBT can be temporarily inserted into the RF line. Therefore, the RF jumper cable will be
dis-connected from the BTS/Node-B and connected to the bottom SBT. Then a short RET jumper
cable is attached to the bottom SBT and the portable controller. See Figure 2-3, Option 3B.
After the successful firmware update, the bottom SBT will be removed again and the RF cable is
attached to the BTS/Node-B. See Figure 2-3, Option 3A.
Note: Please ensure the proper installation direction when connecting the SBTs.
