Not Supported Applications

A main rule in the segmenting is that segment numbers have to follow a line without branches. At next

are shown some application examples which are not covered by the DSLC-2 / MSLC-2 system. The

application in Figure 8-7 and Figure 8-8 shows how the segment number line can branch. Another indi-

cation is the need for a segment breaker between segment 3 and 5, which does not exists.
