Advance Information
In DN, Dual Port mode, the DNIC receives a D-Channel on CDSTi while transmitting a D-Channel on CDSTo.
Fifteen channel times later (halfway through the frame) a C-Channel is received on CDSTi while a C-Channel is
transmitted on CDSTo. The timeslot assignment used by the DNIC is shown in Fig. 29.
In Figure 28, on page 70, timeslots 4-11 and 20-27 are allocated for the 8 DNICs. Timeslots 4-11 contain the
B1 channels on STi/o0 and D-channels on STi/o1. Timeslots 20-27 contain the B2 channels on STi/o0 and C-
