This section describes the fields in the Wide Area DDS configuration window.
DDS Line Mode —
Displays the DDS Line Mode. The selections for this field are DDS-PRI 56K

The default setting is DDS-PRI 56K.

its timing information internally. If DDS-CC 64K was chosen for the DDS Line Mode then this
field must be set to Loop Timing. The default setting for this field is Loop Timing.
DDS Loop Back —
Displays the internal loopback as either Line Loop or No Loop. Line Loop is
reserved for network diagnostics only. The default setting is No Loop.

either Frame Relay or PPP. The default setting for this field is PPP.
Link Management Protocol —
If Frame Relay is the selected protocol, this field displays Q.933
Annex A and T1.617 Annex D. The default for Frame Relay is T1.617 Annex D. This field is
grayed out and not used for PPP.
