Figure 2-1 ARS Process
If the telephone's FRL is equal to or greater than the FRL of the first route (for
example, the telephone's FRL is 4 and the route's FRL is 3) and if the route is
available, the call is put through. If the route is busy, the FRL of the second route
is checked and, if the telephone has the appropriate FRL the call is put through.
If fhe second route is busy. the process is repeated for the third route, and so on
until ARS finds an available route.
Note: If all routes are in use, Callback can be used to queue the call and wait
for an opening in the first route. Callback will not queue a call for any other
route.
The flow chart in Figure 2-1 illustrates the ARS process.
