4.3.3.1 Frame Length

The Frame Length of the 802.15.4 frame depends on the telegram type (data telegram or

commissioning telegram), the Device ID (identifying the device type as described in Chapter

4.4.1.1) and the length of the command list transmitted as part of the commissioning tele-

gram (as discussed in Chapter 4.4.2.3). Table 5 below lists the telegram length for the sup-

ported telegram types.
