2. CPRI Application FTTA (Layer 2)
Antenna
CPRI Layer 2 RRH Initialization
Use the T-BERD to verify provisioning and Radio Head initialization at the top of the tower
Application
Initialize an RRH and measure basic CPRI parameters such as
Initialization Start Up Sequence
C&M Channel Type (Fast vs HDLC)
Protocol ID
Line Rate (Freq Rx)
Problems Solved
Enables users to verify basic RRH CPRI port operation, provisioning and initialization. Therefore, verifying basic RRH CPRI operation from the bottom of the tower.
RRH
COAX
Fiber
T-BERD

3. Identify problems with fiber link and SFP in BBU and RRH

4. Check the RRH SFP

5. Check RRH Serial Number, Manufacturer, and SW Version

6. Check the RTD to RRH (indication for distance/cable length)
RRH Delay
Fiber Delay

7. Turn-up CPRI links easily

8. Launch CPRI Workflow

9. Configure

10. Pick preset Profiles for your job (with types of optics, measurement thresholds etc)

11. Validate SFP

12. Run Test: check Power/Frequency, Layer 1 & 2

13. Create report

14. Repeat test or create report
