6. NA Tier 1 customer : VRAN network without on-path support.

7. Network Setup with TP4100 Slave TC14

8. TC14 TP4100 Slave Results
First 18 hours of Reference Client with 3 HOP TC14 Traffic Loading on Verizon 3 Hop Mobile Backhaul Demo Network. Started with none loaded connection and the TC 14 traffic load started nominally 1 hour into test window.

9. TC14 TP4100 Slave Results
The graph below shows the cumulative time error distribution of the reference client. The 90% performance is within 100ns dynamic accuracy under the TC14 3 Hop Test condition.

10. Static 40%30% and TC14 TP4100 Slave Results
First 18 hours of Reference Client with 2 HOP TC14 Traffic on 10G links and Loading on 1G links to see contribution of the 1G portion to time accuracy.

11. Static 40%30% and TC14 TP4100 Slave Results
The dynamic accuracy under this test is now 50ns with 90% confidence. This shows that half of the accuracy budget is consumed by the 7750 operating with TC14 dynamic load tests.
