Figure 3-7: Example of Network Topology
3. Verify that the BU is set to operate with RIU:
 Click on the BU item in the Network Topology Tree  Select RF Parameters Tab
from the Work Area  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  Select RF Parameters Tab from
the Work Area  Adjust Max Input Power by clicking on the Adjust button in the DL
Power section  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.
