Use the Loop Down Remote test to terminate the remote loopback.
You can run the Loop Up Remote and Loop Down Remote tests from the front panel.
Refer to Chapter 5, The Front Panel.
Figure 6-5 Loop Up Remote Test
NOTE: The full bandwidth loop up code puts the remote DSU/CSU in a full
bandwidth network loopback. The fractional loop up code puts the DSU/CSU in a
fractional (per individual port) payload loopback.
