FCC NOTICE
This device complies with Part 15 of the FCC rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
NOTE:
This equipment has been tested and found to comply with the limits for a ClassA digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial environment.
This equipment uses, generates, and can radiate radio frequency energy and if not installed in

Network Loopback is a testing procedure that segments the line and
allows the user to isolate faults. The selections for this field toggle
between None and Line-Loop. In Line-Loop all 24 channels are looped
back to the T-1 line.The WPIM-T1 must be in Loop-Timing mode to use
this option. The default setting is
None
.
2.1.3 TheWPIMTimeslot ConfigurationTable
The WPIM Timeslot Configuration table allows you to configure the way
in which the Cabletron 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 entireT-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.
You can utilize Timeslots any way you choose. The WPIM-T1 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 T-1 (24 Timeslots), and you want to communicate with
two other sites, your configuration might look like Figure 2-2.

Telco Cloud
24 Timeslots

1482_02
CHAPTER 2: LOCAL MANAGEMENT
2-6 WPIM-T1 LOCAL MANAGEMENT GUIDE
Figure 2-3 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 T-1 Timeslots.Your
service provider will tell you which Timeslots are active.
Figure 2-3. Sample Configuration
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.

addresses.
Circuit State: Toggles between Active, Inactive and Invalid.
THE WAN INTERFACE CONFIGURATION SCREEN
WPIM-T1 LOCAL MANAGEMENT GUIDE 2-9
PT#
Displays the application ports (bridge ports) available from the host
platform to the WAN. If the active protocol is PPP, Local Management
assigns only one application port per interface number (IF#). If the active
protocol is Frame Relay, Local Management assigns the available WAN
bridge ports from the host platform, one per DLCI.
You can assign WAN application ports to the 24 interfaces for the PPP
configuration that suits your needs. In a Frame Relay configuration, you
can assign all WAN application ports to one interface. In this example, the
remaining 23 interfaces would not have WAN application ports available.
The quantity of application ports for a Frame Relay network is
determined by the quantity of DLCIs (Data Link Connection Identifiers)
assigned to that Interface. This is determined either manually or by the
