About ZyXEL Omni 56K USB Lite
The Omni 56K USB Lite is an analog Data/Fax/Voice modem used for Internet access via the PSTN (Public-
Switched Telephone Network) line. It supports the convenience of Universal Serial Bus (USB) connection to
PC. Users can plug and play USB cables without turning off the computer and since the modem is "bus
powered", you do not need to plug in a power adapter, offering true simplicity and energy efficiency. It can
run an upstream maximum rate of 33.6Kbps and downstream rate of 56Kbps. The rate selection depends on
the line quality and server side configuration.
