Site #1 is using the full T-1, so all the Timeslots must have an Interface
assignment. Site #2 and Site #3 only use a fraction of the T-1, but the total
quantity of Timeslots must match those of Site #1. Unused Timeslots
receive an Interface number of 000.
Mapping Unused Timeslots
In the previous example, the WPIM-DI made use of all 24 timeslots.
None of the timeslots were mapped to another device and the Drop and
Insert function was not used. If, however, you wanted another WAN
device (e.g., a WPIM-T1) at the same site as the WPIM-DI to be able to
communicate with Site #3, your configuration might look like the sample
configuration shown in Figure 2-4.
Figure 2-4
Sample Network Configuration #2
Figure 2-5 shows a sample timeslot configuration for the network shown
in Figure 2-4. Of the 24 Timeslots, the WPIM-DI at Site #1A uses 16 to
communicate with Site #2 and the remaining 8 are mapped to the
WPIM-T1 at Site #1B. The WPIM-T1 at Site #1B uses these to
communicate with Site #3. This configuration varies tremendously
depending on how the service provider maps out the T-1 Timeslots. Your
service provider will tell you which Timeslots are active.
NOTE
The Interface numbers of Site #1, Site #2 and Site #3 do not
have to match. Only the quantity of Timeslots must match (the
service provider assigns the Timeslots).
