Data Sheet
The availability of the line interface D channel is indicated in bit 5 "Stop/Go" (S/G) of the
DD last octet of channel 2 (figure 34).
S/G = 1 : stop
S/G = 0 : go
Figure 34
Structure of Last Octet of Ch2 on DD
The Stop/Go bit is available to other layer-2 devices connected to the IOM to determine
if they can access the D channel of the line interface.
