control is sent to Step 10, where the 
route-to number
 command sends the call to 
vector 60, which allows the caller to leave a recorded message.  The first step of 
vector 60 contains an 
announcement
 command, which is not skipped, since the 
treatment step is 
not
 the first non-
goto
 step branched to by a 
goto
 step that 
follows an adjunct routing command whose ASAI link is down [the 
route-to 
number
 step (Step 10) in vector 40 is the first such step].  Similarly, neither the 
wait-time
 step (Step 2) nor the second 
announcement
 step (Step 4) is skipped.
Returning to Step 7 in vector 40, let’s assume that there are 50 or fewer calls in 
queue.  In such a case, the 
goto
 step fails and, as a result, the 
announcement
 
step (Step 8) that immediately follows this step is skipped. (Remember, even 
though this 
goto
 step does not immediately follow the 
adjunct routing
 step, the 
former step qualifies as a test case because it is branched to by another 
goto
 
step that does immediately follow the adjunct ro
uting
 step.) Thereafter, the 
goto 
vector
 step (Step 9) routes the call again to vector 50, which is designed to 
queue the call and provide standard call treatment.
The following table summarizes the procedures discussed in this section.  In so 
doing, the table refers back to the vectors presented in the previous screen.
Awaiting the Response to the Call Route Request
After the switch sends a route request to the ASAI adjunct, vector processing 
continues with the following vector steps.
The step that follows the 
adjunct routing
 step in effect determines the maximum 
length of time the switch will wait for the ASAI adjunct to reply with a call route.
