Again, for this example only, the dial back-up 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 Montgomery unit
in this example in conjunction with enabling the DBU criteria and DBU on Inactive would be all the pro-
gramming required for normal dial backup from Montgomery.

DBU C
ALL
O
RDER
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
DBU O
N
I
NACTIVE
parameter is disabled by default. For this example, leave it disabled in order
to assure the
G
ROUP
parameter on the host unit will initiate dial backup.
At this point all PVC options have been configured for basic Frame Relay dial backup from Mobile to
Huntsville. The PVC entries on the Mobile IQ 710 should look like the screen shown in Figure 31. The
remaining options may be left at their default values. The
