The Data Connect ST3342LP


For industrial networks, data centers and remote management application that require high-speed connections, the Data Connect ST3342LP family of wire line data modems incorporates the latest advances in modem design to deliver efficient and reliable performance that is packaged for industrial and commercial applications. ST3342LP series modems offer superior price/performance and robust features set that will meet or exceed your communications needs.
Complex network configuration often incorporate a variety of data set interfaces, each requiring separate modem types. The result has been a requirement to stock seldom used parts, often in significant quantity.  Now, the DCE ST3342LP series offers an all-in-one solution for a wide range of applications. Packaged in either a polymer or metal case, and backed by a five year warranty, the ST3342LP series is capable of operating in either 2 or 4 wire configurations on dial up, leased line, or short haul networks. Protocol support includes V.34, V.32, V.32bis as well as Bell 212A and 103j.
With its standard power saving standby mode and instantaneous (zero character loss) recovery, the ST3342LP series reduces stocking and spares cost while providing additional project flexibility. ST3342LP series modems have been developed to meet the strident environmental and performance demands of the commercial and industrial applications. Every component, switch and connector is selected for its ability to withstand industrial environmental demands. ST3342LP series models may be housed in optional metal enclosures and are built to meet the most stringent criteria. Temperature ratings, for stringent example, range from -20 C to +70˚C. Versatile power supply options will satisfy any industrial application. Available in commercial and industrial standalone configurations
