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 (primary) and DDS-CC 64K (clear channel). This information is supplied by the service provider. The default setting is DDS-PRI 56K.

DDS Clock Source — Displays the DDS clock source. The selections for this field are either Loop Timing or Local Timing. The Loop Timing setting allows the HSIM-W6 to receive its timing information from the service provider. The Local Timing setting allows the HSIM-W6 to generate 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.

Protocol — Displays the active protocol for the DDS WAN port. The selections for this field are 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.

Once WAN configuration is complete, click on the Next>> button in the DDS WAN configuration window and proceed to the Bridging and Routing Configuration section of this guide.
