Preface
Thank you for purchasing the ZyXEL Omni 56K USB modem.
About ZyXEL Omni 56K USB
The Omni 56K USB 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.
