The value assigned to the timeslots is the interface being used
for WAN communication. The next available interface is
displayed on the WAN Physical Configuration screen in the
Next IF field (see
Figure 3-1 ). The Next IF number shown must
be used to add a new interface. The Next IF will increment as
interfaces are added. The previously entered interfaces can be
modified by entering the interface number.
