Find firmware at www.zyxel.com in a file that (usually) uses the system model name with a 
.bin extension, for example, "ZyXEL.bin". The upload process uses HTTP (Hypertext 
Transfer Protocol) and may take up to two minutes. After a successful upload, the system will 
reboot.

Note: Only use firmware for your device’s specific model. Refer to the label on the 

bottom of your device.

Click Firmware to open the following screen. Follow the instructions in this screen to upload 
firmware to your ZyXEL Device.

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 ZyXEL Device

back) to the ZyXEL Device. The ATM loopback test is useful for troubleshooting 

problems with the DSLAM and ATM network.
