DS3 Payload Loopback

During this test, all payload information is re-framed and looped back towards the network. See Figure 6-3for a block diagram illustrating the loopback point and the signal paths for this test.

This test does not interrupt data flow from the network to the DTE, but it does block all DTE-to-network data.
