Click this to start the ATM loopback test. Make sure you have

configured at least one PVC with proper VPIs/VCIs before you

begin this test. The ZyXEL Device sends an OAM F5 packet to the

DSLAM/ATM switch and then returns it (loops it back) to the

ZyXEL Device. The ATM loopback test is useful for troubleshooting

problems with the DSLAM and ATM network.
