3. Verify that the BU is set to operate with RIU:
• Click on the BU item in the Network Topology Tree Æ Select RF Parameters Tab
from the Work Area Æ Interface Type to MA RIU
• Optional: Assign the BU an identifiable name by Modifying the Name parameter in the
Module Info tab
4. Using a Fiber Optic Tester, verify that the UL Optical Link Level of the fiber connected to the
BU is >0
• Set the Fiber Optic Tester to a wavelength of 1310nm
• Unplug the UL fiber connection from the BU and test to make sure it is at a level >0
• If the level is not >0, clean the fiber and retest
5. Set up CW signal to be connected to the signal conditioner (BTSC/BDAC). The 700 MHz LTE
conditioner does not need an external CW signal (See Section 3.4.2).
• BTSC acceptable input power range = +10 to +36dBm
• BDAC acceptable input power range = -16 to +10 dBm
• Acceptable frequency range depends upon the RF service
6. Adjust the signal conditioner (BTSC/BDAC) with the CW signal. The 700 MHz LTE conditioner
does not need an external CW signal. (See Section 3.4.2).
• Connect the CW signal to the BTSC/BDAC DL Port or Duplex port located on the rear of
the RIU associated with the slot that the signal conditioner (BTSC/BDAC) is inserted into
• Click on the conditioner in the Network Topology Tree Æ Select RF Parameters Tab from
the Work Area Æ Adjust Max Input Power by clicking on the Adjust button in the DL
Power section Æ Select Use Current Input Power
• After a few moments, verify that the Target Max Input Power and the Current Input
Power are equivalent
7. Repeat Step
6 for each signal conditioner
8. Perform a Quality and Integrity Check of the installed system as per the RF Design and
Statement of Work. Contact a MobileAccess Project Manager for more instructions.
