Currently only the EDM card supports both the STC and l4l7 test packages at the same time across different ports.
To enable this do the following: - Open the Spirent TestCenter Firmware Manager from the Spirent TestCenter GUI - Select 'active test package' - Select ports to change active package - Select STC or l4l7 from the 'new test package' pull down - Click 'Active' and watch the GUI for status
