5.8.4. ATB<br />
In the ATB world a parametric table, or pectab, is used to display the data on the document.<br />
Migrating from ATB to <strong>BCBP</strong> requires reprogramming the pectab in the host to include a bar<br />
code.<br />
In the ATB model, the host sends the data as well as the pectab in order to print the ATB (see<br />
fig. 53). Format code W is the ATB2 magnetic stripes specifications defined in Resolution 722c<br />
attachment ‘C’.<br />

The ATB reader decodes the data stored in the magnetic stripe according to format code W and<br />
transmits the data to the boarding application (see fig. 54).<br />

5.8.5. <strong>BCBP</strong><br />
Implementing <strong>BCBP</strong> natively means that the airline programmes the host so that it sends a<br />
<strong>BCBP</strong> stream (see fig. 55).<br />
