The WPIM Timeslot Configuration Table
The WPIM Timeslot Configuration Table allows the user to configure the way in which the
Cabletron WAN module uses the E1 line. The configuration table consists of 32 timeslots. Only 31
of the timeslots are available for use, because the first timeslot is used by the device to transmit
framing data. N/A (Not Available) always displays in Timeslot #1. You must assign each of the
remaining 31 timeslots an Interface number (for example, 002 for an active Interface number or
000 if the timeslot is not used). When you lease an entire E1 line, you can use all 31 timeslots (the
full E1 bandwidth). If you lease only a fraction of the E1, the service provider tells you which
timeslots to use.

You can utilize timeslots any way you choose. The WPIM-E1 supports Time Division
Multiplexing (TDM) allowing demultiplexing of circuits (timeslots) within the public network.
For example, if you have access to a full E1 (31 customer-usable timeslots), and you want to
communicate with two other sites, your configuration might look like

Sample Timeslot Configuration
shows a sample configuration for three sites. Of the 32 timeslots, Site #1 uses the first
timeslot for transmitting framing data, 23 timeslots to communicate with Site #2 and the
remaining 8 timeslots to communicate with Site #3. This configuration varies tremendously
depending on how the service provider maps out the E1 timeslots. Your service provider will tell
you which timeslots to configure.
