Payload Loopback

This selection initiates a Payload Loopback test for all data on the selected port rather than for the entire DS3. During this test, the data is looped back in the network direction. Perform this test to verify the integrity of the portion of the DS3 link connecting the selected port of the T3SU 300 and the remote DTE. This test is non- intrusive to the three other ports. See Figure 6-6.

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

Figure 6-6. Payload Loopback Test

This selection performs a bit error rate test on the selected port. This test in non-intrusive to the other three ports. Only one BERT test may be performed at a time. This test is normally performed from the remote and local ends simultaneously to determine whether the errors are coming from the transmit or the receive direction. See Figure 6-7.
