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 Mobile unit in
this example in conjunction with enabling the DBU C and DBU I would be all the pro-
RITERIA ON NACTIVE
gramming required for normal dial backup from Mobile.
If the network fails at the Huntsville site, the Huntsville IQ 710 will first attempt to dial the Atlanta IQ 710
since it is configured as call order one. However, if it fails to connect, the Huntsville IQ 710 will attempt
to dial the Montgomery site which is configured as call order two. If that fails to connect, the Huntsville
IQ 710 will attempt to dial the Birmingham site which is configured as call order three. Finally, if that fails
to connect, the Huntsville IQ 710 will attempt to dial the Mobile site which is configured as call order four.
If all the Huntsville IQ 710 call order entries had been set to none, the Huntsville IQ 710 would have used
the first entry with a DBU phone number. In this example, it would have attempted to call the Atlanta IQ
710. If that had failed to connect, the Huntsville IQ 710 would have moved to the next entry with a DBU
phone number (Birmingham site) and so on.
