VT/PORT LOOPBACKS

Chapter 6. Diagnostics

VT/PORT LOOPBACKS

After you select the number that corresponds with the line you want to test, the menu in Figure 6-2 appears. The number selected (1-28) refers to the VT number. The Port (T1/E1) that will be tested is the port mapped to the selected VT number. The sections following the figure provide descriptions and illustrations of the testing options. Select 1-DATAMODE to end a test in progress.

Figure 6-2. VT/Port Diagnostics Menu

Tributary

A TRIBUTARY loopback loops the selected VT/Port back to the network (STS-1). The T1/E1 is looped back through the STS-1 mapper. During this loopback, the corresponding DSX-1/E1 input is overwritten by the outgoing DSX-1/E1 signal. See Figure 6-3 on page 6-3 for an illustration of this test.
