NOTE:
The American firmware version supports both the S/T
interface and U interface models. During the power-on test, it checks
the hardware configuration and follows the initialization procedures

Follow these steps to upgrade you omni.net with flash EPROM, by using a communications
program:

Make sure your omni.net has the power turned ON.
Step 2.

Step 3.
Press 'Y'. The following message then appears:
Start programming, please upload.
Step 4.
Use the Xmodem protocol to upload the file ONETd.vvv to your ISDN TA. This
step updates the omni.net's flash EPROM with the new firmware. When installation
is complete, the omni.net will restart automatically.
