MT3334SMI6

Introduction

The MT3334SMI socket modem provides a fully-integrated data and fax communications design for

communications over wide area networks using dial-up phone lines and the Internet.

This guide provides the Service Class 1 standard defining the commands that the developer can use

to configure and control a fax/data modem and the responses (result codes) that the fax/data modem

issues in response to the commands. This guide also provides the developer with specific Class 2 fax

command protocol used to control the sending and receiving of faxes.

Product Description

The MT3334SMI is a standard 64-pin Socket Modem (Figure 1-1 illustrates the MT3334SMI in

relationship to Multi-Tech’s Demo board) used for integrating data and fax communications. It

provides:

• Low power consumption

• A serial TTL level interface

• Full-featured fax and datacomm operation

• A very small footprint for embedded applications
