Figure I-12. C Segment Slots<br />

e. The segments shown in Figures I-10 through I-14 are <strong>com</strong>plete selections. They<br />

facilitate understading how the controller determines the number of users that may<br />

simultaneously use a channel without causing interference. The first item considered is<br />

the data rate of the baseband device. This is indicated by the first number in each<br />

block. The second item considered is the burst rate, which can be one of three<br />

selections. On good channels, the burst rate can be as high as 32-kilosymbol(s) per<br />

second; on noisier channels (or channels with disadvantaged users), the burst rate is<br />

lowered to 19.2- or 9.6-kilosymbol(s) per second to increase the likelihood of successful<br />

<strong>com</strong>munication. The encoding rate also plays a major role, especially with the<br />

disadvantaged users on the DAMA channels.<br />
