6.4.3Assigning B Channels to One D Channel
B channels are assigned to the highlighted D channel by placing the cursor in the row representing the WAN link (interface) and the column representing the timeslot. Pressing the “Enter” key will place a lowercase “b” in that timeslot (the "Enter" key toggles the "b" off and on). This indicates that you have designated this timeslot as a B channel to be controlled by the highlighted D channel. You will not be able to place a “b” in any timeslot that is currently occupied by a letter, number or dash, because these timeslots are controlled by other system modules, thus are unavailable to this D channel.
Figure 6-11 shows 36 B channels assigned to D channel #1. In this example, the carrier requested that you use timeslots 1-9 on WAN 1-1, timeslots 11-19 on WAN 1-2, timeslots 1-9 on WAN 2-1 and timeslots 1-9 on WAN 2-2.
