Wireless PTP link not passing Y.1564 certification Test

We have a customer who is requiring us to pass a Y.1564 certification test. The customer is connected via netmetal (RB921UAGS-5SHPacD) using 5Ghz using nstreme to another netmetal (RB921UAGS-5SHPacD). The link is 11.8 miles. SNR is between 40/42. CCQ hovers around 95%. The link is failing the Y.1564 test that is being performed with a Anristu MU909060A. On one side of the link the netmetal is setup as a AP Bridge while the other netmetal is configured as a station bridge. Basically a layer2 bridge for the customer’s network. Any suggestions or recommendations would be greatly appreciated.

Thank you!

And how are thresholds set and which one doesn’t pass?
