Getting to Know Your Modem 1-1
Chapter 1
Getting To Know Your Modem
This chapter introduces you to the features and specifications for the ZyXEL Omni 56K Smart
modem.
1.1 The Omni 56K Smart Modem
The Omni 56K Smart is analog Data/Fax modem used for Internet access via telephone wire. The modem
can run upstream maximum rates of 33.6 kilobits per second (Kbps) and downstream rates of 56Kbps. The
actual rate depends on the line quality, the distance to the exchange and server side configuration.
1.2 Features of the Omni 56K Smart Modem
ZyDAS Sixth Generation Data Pump with V.90 Capability
The Omni 56K Smart modem complies with the V.90 standard for data communications. This means that
your modem is able to communicate at 56K on data communications originating from your service provider.
Microsoft Windows 95/98/2000/Me/XP: RS-232 Plug and Play Compatible
Your modem provides the convenience of simply being connected to the serial port on your computer. The
serial port is a dedicated communications port and allows for optimum data speeds between your computer
and modem.
V.34bis 33.6K Data Transmission Rate
Upstream communication rates of up to 33.6K are possible with the V.34bis protocol. The Omni 56K Smart
modem complies to the V.34bis protocol and this provides an effective transmission speed of 33.6K when
connection is made to a service provider that utilizes the same protocol.
Automatic Data/Fax Call Detection
The Omni 56K Smart modem can automatically answer an incoming call and ascertain whether that call is a
data or a fax call.

Omni 56K Smart User’s Guide
1-2 Getting To Know Your Modem
G3 14.4Kbps Fax Send/Receive
Your modem supports the V.17 fax standard that will allow for fax speeds of up to 14400 bps when
transmitting to another V.17 fax machine. When connecting to an earlier G3 fax device, your modem
operates at speeds up to 9600.
Support Fax Class 1, Class 2 and Class 2.0 Command Set
The fax facilities as offered on the Omni 56K Smart modem provides full compatibility with the class 1, class
2 and class 2.0 command sets. This compatibility means that your fax modem is fully configurable with a
wider range of options that can be optimized if need be.
Data Compression and Error Correction
Data compression is utilized to reduce the number of bits actually sent and received. This saves on the actual
amount of data being sent and therefore increases the modem's speed (or throughput). Error correction
protocols are used so that the compressed data can be accurately decompressed on the receiving end.
Omni 56K Smart modem supports V.42bis and MNP5 data compression protocols as well as MNP4/V.42
error correction. MNP5 is used with MNP4 error control; V.42bis is used with V.42 error control. The
compression efficiency of V.42bis is generally higher than that of MNP5.
