4.4.4 Assignments for Two or More D Channels
Previous paragraphs dealt with multiple B channels for a single D channel. Often, the system
will be called upon to manage the ISDN communication for more than one D channel, as
described earlier in this chapter.
In Figure 4-13, D channel #2 is changed from stdby to conf and is assigned to timeslot #24
on WAN 1-2.
Figure 4-13. Assigning B Channels
When the Bmap selection is made (with D channel 2 highlighted), D channel #2 appears on
WAN 1-2, timeslot 24.
DS0s are still represented by “x”s. B channels which have already been assigned to D channel
#1 (and are therefore unavailable to D channel #2) are represented by “1”s.
Using the same procedure learned in the previous section, assign a lowercase "b" to each
timeslot assigned by the carrier by pressing the “Enter” key in the column and row on the
screen. In this example, timeslots #11-22 on WAN 2-1, #11-22 on WAN 2-2 and #1-24 on
WAN 3-1 are assigned as B channels for D channel #2.
Remember to save your work before pressing “m” to return to the top level D channel
configuration screen.
