T1 Network Loopback
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 The WPIM Timeslot Configuration Table
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 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.
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.
