LABEL DESCRIPTION
Reset VDSL
Line
Click this button to reinitialize the VDSL line. The large text box above then displays
the progress and results of this operation, for example:
"Start to reset VDSL
Loading VDSL modem F/W...
Reset VDSL Line Successfully!"
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.
Back Click this button to go back to the main Diagnostic screen.
12.5 Firmware Screen
Find firmware at www.zyxel.com in a file that (usually) uses the system model name with a
.bin extension, for example, "Prestige.bin". The upload process uses HTTP (Hypertext
Transfer Protocol) and may take up to two minutes. After a successful upload, the system will
reboot. See
Chapter 24 on page 214 for upgrading firmware using FTP/TFTP commands.
