Data Sheet
Figure 19 shows the timing of shifting data from TSa to TSb on DU(DD). In figure 19a)
shifting is done in one frame because TSa and TSb didn’t succeed direct one another
(a,b = 0...9 and b
frame. This is the case when the time slots succeed one other (b = a+1) or b is smaller
than a (b < a).
