We're doing the test for LTE modem with service providers.
I suggest you direct your questions directly to the Meraki staffer who provided the MX, in the first place.
I have had MNO clients for some decades, in my experience the MNO's contractor works with the equipment manufacturer and the appropriate standards authorities to set up test environments and execute one or more of a series of tests to establish the equipment's performance and compliance with standards.
The questions you are asking, can be quickly answered by a Meraki engineer. You should also contact the manufacturer, in this case Gemalto, part of the Thales Group.
