Configuration with QuickSET
84 QuickSET Configuration Guide
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 device to receive its timing
information from the service provider. The Local-Timing setting allows the device 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 — The Protocol panel lets you select one of four protocols: Point-to-Point, HDLC
(High Level Data Link Control), Frame Relay Point-to-Point, Frame Relay Point-to-Multipoint.
High Level Data Link Control lets you select either Full or Fractional mode for all or half of the
time slots (for a single interface number and alias). Point-to-Point protocol lets you select an
interface number for each time slot. Frame Relay Point-to-Multipoint allows only one interface
number and alias, but allows multiple DLCIs. Frame Relay Point-to-Point allows multiple
interface numbers, aliases, and DLCIs.
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.
DLCI Button — The DLCI Setup button displays the DLCIs window shown in Figure 91. The
DLCIs window shows a list of Interface Numbers, Aliases, and DLCIs (Data Link Connection
Identifiers). Use the Add button and Add DLCI window (Figure 92) to make new entries to this
table. Use the Delete button to delete the entry highlighted. Click Done when you have finished.
