connections. Circuit-switched data connections support speeds up to 14.4K bps, Class 1 and Class 2 Group 3
fax, as well as MNP2 V.42bis compression. CSD cellular wireless connections are ideal for applications that
require a quick wireless replacement of an existing point-to-point analog dial-up connection. They integrate
seamlessly with your current application requiring little infrastructure change.
Internet-Enabled. The MultiModem® EDGE includes an embedded TCP/IP protocol stack to bring Internet
connectivity to any device. Using the embedded Internet protocols and the wireless connection to an IP
network, it sends and receives data over the Internet. It can also serve a single web page in response to a
