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.

How to Use This Guide

This Guide is divided into 5 chapters. The first two chapters provide general information for
ZyXEL Omni 56K USB modem, and the next three chapters provide advanced information for
technical users who might need them for programming or other applications.

Flow Control

This feature refers to stopping and restarting the flow of data into and out of the modem’s
transmission and receiving data buffers. Flow control is necessary so that a device does not
receive more data than it can handle. The Omni 56K USB provides two kinds of flow control
methods.

Hardware CTS/RTS Flow Control

This is a bi-directional flow control where CTS and RTS are simulated RS-232C signals that
must be available on your computer. When the modem’s transmission buffer is almost full, the
modem drops CTS to signal the DTE that it cannot accept data any more. Turn on the CTS to
notify the DTE that it can keep sending data to the modem. On the computer software side,
when the receiving buffer of the software is almost full, it drops RTS to signal the modem to
stop sending data to the DTE. Turn on the RTS and the modem starts sending data again to the
DTE.
