Figure 6-17. Payload and DTE Loopback Test
Remote Port Payload Loopback
During this test, the local unit commands the far-end unit to
perform a payload loopback test for the selected Quad DSX-1
interface card. This results in all of the DSX-1 interfaces in the local
unit being looped back. See Figure 6-18 for an illustration of this
test.
