5.3.7 Assigning 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 (interf ace ) 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 thes e timeslots ar e controlle d by other
system modules, thus are unavailable to this D channel.
Figure 5-11 shows 36 B channels assigned to D channel #1. In this example, the carrier
requested that you use timeslots 1-9 on W AN 1-1, t imeslots 11-19 on WAN 1-2, timeslots 1-9
on WAN 2-1 and timeslots 1-9 on WAN 2-2.
