Loopback Test Select a port number from the Port drop-down list box and enter a
VPI/VCI to specify a PVC. Click OAM F5 Loopback to perform an
OAMF5 loopback test on the specified DSL port. An Operational,
Administration and Maintenance Function 5 test is used to test the
connection between two DSL devices. First, the DSL devices establish
a virtual circuit. Then the local device sends an ATM F5 cell to be
returned by the remote DSL device (both DSL devices must support
ATM F5 in order to use this test). The results (“Passed” or “Failed”)
display in the multi-line text box.
LDM Test Select a port number from the Port drop-down list box and click Set
LDM Port to have the IES-1248-51V perform line diagnostics on the
specified port. The ADSL port must be set to ADSL2 or ADSL2+ ADSL
operational mode and have a connection. It takes about one minute
for the line diagnostics to finish. The screen displays a message
confirming upon which ADSL port line diagnostics will be performed.
Click Get LDM Data to display the line diagnostics results after using
the Set LDM Port button on an ADSL port. Use the line diagnostics
results to analyze problems with the physical ADSL line.
Click Get LDM Data(raw) to display the unformatted line diagnostics
results.
Click Get LDM Data(992.3) to display the line diagnostics results in
the format defined in the ITU-T G.992.3 standard.
Note: Wait at least one minute after using Set LDM Port before
using Get LDM Data.
