Reset ADSL 

Line

Click this button to reinitialize the ADSL line. The large text box above then displays 

the progress and results of this operation, for example:

"Start to reset ADSL

ATM Loopback 

Test

Click this button 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 Prestige sends 

an OAM F5 packet to the DSLAM/ATM switch and then returns it (loops it back) to the 

Prestige. The ATM loopback test is useful for troubleshooting problems with the 

DSLAM and ATM network.
