Figure 6-9. Payload and DTE Loopback Test Remote Port Payload Loopback

This selection initiates a Payload Loopback on the remote T3SU 300 for all data on the selected port. Perform this test to verify the integrity of the portion of the DS3 link connecting the local DTE and the selected port of the remote T3SU 300. All other ports on both the local and remote units are unaffected.

Remote Payload Loopback with BERT

Perform this test to verify the integrity of the link between the selected port of the local T3SU 300 and the corresponding remote T3SU 300 port. During this test, the remote unit loops back all data for the selected port, while the local unit sends and checks the selected BERT pattern. The loopback point and the signal paths for the remote T3SU 300 are the same as the Payload Loopback test for the local T3SU 300 (shown in Figure 6-6).
