Click Maintenance > Diagnostic > OAM Ping to open the screen shown next. Use this screen to
perform an OAM (Operation, Administration and Maintenance) F4 or F5 loopback test on a PVC. The
VMG sends an OAM F4 or F5 packet to the DSLAM or ATM switch and then returns it to the VMG.
The test result then displays in the text box.
ATM sets up virtual circuits over which end systems communicate. The terminology for virtual
circuits is as follows:
• Virtual Channel (VC)
• Virtual Path (VP)
• Virtual Circuits
