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.
