1. Introduction<br />
<strong>Dollar</strong> <strong>General</strong> is tasking Spacenet to provide data communication services to its retail<br />
stores in the United States. Spacenet’s <strong>VSAT</strong> network provides store connectivity for:<br />
� Xcellenet polling<br />
� Check authorization<br />
� On-line inventory management.<br />
� Calling Card Activation<br />
The <strong>VSAT</strong> service includes MSK modulation on the inbound side and Reed Solomon<br />
coding on the outbound side. The outbound data rate is 1 Mbps, QPSK, requiring a<br />
phase–locked loop (PLL) low noise block converter (LNB). The inbound rate is 76.8<br />
kbps. The Satellite is GE–5, Transponder 2, Horizontal Polarity.<br />
1.1 Interface Type<br />
Ethernet ports will be available on both the IDU and customer’s equipment, most likely<br />
an Ethernet <strong>Hub</strong> connected to a Server Register. Use a RJ–45 straight thru cable to<br />
