The Wpim Timeslot Configuration Table - Enterasys WPIM-E1 Network Manual

2.1.3 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 E-1 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 appears 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 E-1 line, you can use all
31 Timeslots (the full E-1 bandwidth). If you lease only a fraction of the
E-1, the service provider tells you which Timeslots to use.
The WPIM-E1 always uses the first Timeslot (Timeslot #1) to
transmit framing data. A full E-1 line with 32 Timeslots has
NOTE
31 customer-usable Timeslots.
You can utilize Timeslots any way you choose. The WPIM-E1 supports
Time Division Multiplexing (TDM) allowing channelization of circuits
(Timeslots) within the public network. For example, if your BRIM-W6
has access to a full E-1 (31 customer-usable Timeslots), and you want to
communicate with two other sites, your configuration might look like
Figure 2-2.
