The E-450/G is a GSM and CDMA Mobile Stations device capable of using GSM and CDMA Circuit Switched Data (CSD), Fax and Short Message Services (SMS)communications and output. The E-450/G is a quad band, GPRS device communicating at GSM850 / EGSM900 / DCS1800 / PCS1900 MHz, Class 10 GPRS data packet transfer and CDMA450Mhz band A-B. It has an embedded TCP/IP stack and DNS query protocol supporting static and dynamic IP address allocation, PPP, UDP and FTP functionality.

Programming of the E-450/G DTU in use is either via the Forwell Wireless provided configuration utility, or via AT Commands. Connection to the host controller (Data Terminal Equipment DTE) is established through one RS232 standard port which also performs serial bidirectional Data and Fax transfer. Use of the E-450/G will require third party products and/or services such as telecommunications access.
