2.37.2 Sub-communication channel for 1CB arrangement
(i) Normal (N=1) communication
Figure 2.37-2 shows the Normal frame that is defined in the IEEE C37.94 standard as N=1†.
When Normal is applied, sub-communication channels are provided at bits: COM1(2bits). The
use of the sub-communication channels are not restricted, hence the user can use them for
sending user-wishing data.
