WPIM-DI Timeslot Configuration Table
The WPIM Timeslot Configuration table allows you to configure the way in which the WAN
module uses the T-1 line. The configuration table consists of 24 timeslots. You must assign each
timeslot an Interface number (for example, 002 for an active Interface number or 000 if the
timeslot is not used). When you lease an entire T-1 line, you can use all 24 timeslots (the full T-1
bandwidth). If you lease only a fraction of the T-1, the service provider tells you which timeslots to
use.
The WPIM-DI supports Time Division Multiplexing (TDM) allowing channelization of circuits
(Timeslots) within the public network. You can use timeslots any way you choose. When using the
WPIM-DI, you have the option of implementing all the available leased timeslots with the
WPIM-DI, or you may map any of the available timeslots to another WAN module through the DI
interface.
Figure C-2 Sample Network Configuration
Figure C-3 shows a sample timeslot configuration for the network shown in Figure C-2. 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
When the diDataEnable option is selected in the DI Enabled field, data from the host
device passes through the DI port and not the NI port on the host platform.
