The configuration fields displayed on the WAN Physical Configuration
screen shown in
Figure 4-1 are specific to the DDS mode of the
WPIM-T1/DDS.
DDS Line Mode (Toggle)

(primary) and DDS-CC (clear channel). This field should be set according
to information from the service provider. The default setting for this field
is DDS-PRI.

DDS-CC is chosen for the DDS Line Mode then this field must be set to
Loop. The default setting is Loop.

Displays the internal Loopback as either Line-Loop or None. Line
loopback is reserved for network diagnostics only. The default is None.
