Description

The external modem provides communications over switched telephone lines. It has the following
important features:
• Powered by +5 Vdc through a serial port by most SEL devices or,alternatively, through a separate AC transformer.
• Metal enclosure.
• Operating temperature range of –20°C to +70°C.
A commitment to constant improvement keeps Data Connect
communications products ahead of the industry in quality and
performance. Our 14.4Kbps models incorporate the latest
advancements in modem design to deliver more performance,
more features and higher reliability.
Our 14.4Kbps models provide a complete implementation of the ITU-T V.32bis standard for
14.4Kbps operation. In addition, all designs offer complete compatibility with older standards
such as V.32 and V.22bis.
