Timeslots can be utilized in any way chosen. The WPIM-T1/DDS in T1
mode supports Time Division Multiplexing (TDM) allowing
channelization of circuits (Timeslots) within the public network. For
example, if the WPIM-T1/DDS has access to a full T1 (24 Timeslots), and
the user wants to communicate with two other sites, the configuration
might look like that shown in
Figure 3-2 .
Figure 3-2 Sample Timeslot Configuration
Figure 3-3 shows a sample configuration for three sites. Of the 24
Timeslots, Site #1 uses 16 to communicate with Site #2 and the remaining
8 to communicate with Site #3. This configuration varies tremendously
depending on how the service provider maps out the T1 Timeslots. The
service provider indicates which Timeslots are active.
