Introduction 
This chapter introduces you to the features and specifications for the ZyXEL Omni 56K USB 
Plus and Omni 56K COM Plus modems. 
1.1  ZyXEL Omni 56K Plus modem Overview 
The Omni 56K USB Plus or Omni 56K COM Plus is an analog Data/Fax modem used for Internet 
access via PSTN line. Models included in this series at the time of writing are the Omni 56K COM 
Plus and the Omni 56K USB Plus. The difference between these two models is: the Omni 56K COM 
Plus uses RS-232 Com port interface and the Omni 56K USB Plus uses Universal Serial Bus (USB) 
connection to a computer. Users can connect the cables without turning off the computer which makes 
it simple to install the modem. It can run upstream and downstream maximum rates of 56Kbps. The 
rate selection depends on the line quality, and server side configuration.
