allows each DLCI listed in the table to be prioritized in the event that multiple
PVCs are lost at once. Dial backup will first be attempted on the PVC with the lowest Call Order
that meets the DBU Criteria settings. Leave this parameter at the default value of none.
The

parameter is disabled by default. For this example, leave it disabled in order
to ensure that the host unit will initiate the dial backup.
At this point all PVC options have been configured for basic Frame Relay dial backup from Atlanta to
Huntsville. The PVC entry on the Atlanta IQ 710 should look like the screen shown in Figure 28.The
remaining options may be left at their default values. The

Again, for this example only, the dial backup will only originate from the Huntsville site (in order to dem-
onstrate the call order parameter). In a normal circuit, the parameters programmed for the Atlanta unit in
this example in conjunction with enabling the

and

would be all the pro-
gramming required for normal dial backup from Atlanta.
