progress and results of this operation, for example:

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.

9.5 Firmware Screen
Find firmware at www.zyxel.com in a file that (usually) uses the system model name with a "*.bin"
extension, e.g., "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 the Firmware and Configuration File
Maintenance chapter in the parts that document the SMT for upgrading firmware using FTP/TFTP
commands.
Only use firmware for your Prestige’s specific model. Refer to the label on the
bottom of your Prestige.
Click Firmware to open the following screen. Follow the instructions in this screen to upload firmware to
your Prestige.
