Send of the DUT is connected to the receive on the tester and the receive on the DUT is connected to the send port of the tester. In the testing scenario, the DUT (Device Under Test) is connected to send and receive ports on a tester. Connections are made from transmit of one device to receive on the other. The media over which the tests are run is the GameChanger cable. In this case, the DUT (Devices Under Test) are a pair of Viavi TBERG 5800 testers.
The tests are available for vendors to use and will provide users with test results in an apples to apples (device to device) fashion in a comparable comparison format. The document identifying the test parameters from IETF (Internet Engineering Task Force) is designed to stop what they call “specmanship” from vendors to give themselves a better position in the marketplace, as they feel this practice often involves smoke and mirrors to confuse the potential users of a product.
