Figure 9.12: Segmentation

• Data from segment 1 are written in receive buffer CU (10 frames) and optically transmitted directly

from there.

• The transmitted data are received by the DT2 and written in receive buffer OP (64 frames >

800 kBit and 128 frames < 800 kBit).

• Data in receive buffer OP are sorted by priority or processed according to the FIFO principle

(depending on the operating mode used)

• Data in receive buffer OP are passed to segment 2 for arbitration.

• The same process also occurs when transmitting data from segment 2 to segment 1.
