5.3.6 Assigning B Channels
Choosing the “Bmap” option from the D channel configuration screen of the ISDN card screen
brings up the subscreen shown in Figure 5-10. This figure shows a typical “Bmap” screen. It
is a detailed map of all the WAN timeslots available to users as potential B channels.
When D channel #1 is placed in the “Configure” mode, the system recognizes the assignment
of WAN 1-1, timeslot #24 to this D channel and places it on the Bmap in the proper location.
Notice that since all WAN links are T1 interfaces, the Bmap shows the last 7 places with a
dash (-) indicating that the timeslot is unavailable for assignment.
