Knowledge Base - FAQ
What is required to support OTN test options on the MSAM bert modules for the 6000A/8000 platforms?
For MSAM version 1 it has to be a dual port unit and tests can only be launched from port 1. MSAM 2 also requires a dual port unit but the test can be launched from either port 1 or port 2.
