4. If the oldest call waiting time is less than 60 seconds, step 4 accepts the 
call and queues it. ADR then connects the call through to the receiving 
PBX/ACD.
5. Steps 5-7 provide ringback, announcement, and music to the caller.
If the vector at location A rejects the c all b y sending a busy indication back to the 
network over the ISDN-PRI link, ADR reroutes the call to location B, which must 
accept the call. If location B is closed or too busy to...

Adjunct Routing
Introduction
Adjunct Routin g allows an associated adjunct to make a call routing d e cision 
when it encounters an 
adjunct routing vector command during vector 
processing.
An adjunct is any p rocessor connected to a switch that can use ASAI features.  
The adjunct makes a routing decision according to caller information and/or 
agent availability, and it returns the routing response to the switch.
Adjunct Routing c an be used in conjunction with Call...

extension, or a particular agent. An adjunct can also provide priority ringing and 
priority queuing.
Sending the Call Route Request
Here’s an example of a simple vector that uses adjunct routing:
Figure 9-1. Adjunct Routing Vector
In this vector, 
1111 is the extension number of an ASAI link.  Each ASAI link has a 
unique extension number, even in a configuration where there might be multiple 
ASAI links to the same adjunct.
When a call encounters an

If the call is queued, the adjunct routing step is ignored, and vector processing 
continues at the next vector step.
NOTE:
For reasons that we discuss later in this chapter, you should always in clude 
a 
wait-time ste p, announcement or another adjunct routing step (G3V3 and 
later releases) after an 
adjunct routing step.
Effects of ASAI Link Failure on Vector Processing
If the ASAI link specified in the adjunct routing step is down, the step is...

The following vectors can be used to illustrate the processes just described.
Figure 9-2. Skipping/Non-Skipping of Treatment Commands 
with ASAI Link Down
Because we are assuming the a djunct link is d own, the 
adjunct routing command 
in Step 1 fails.  Because the 
wait-time command in Step 2 immediately follows an 
adjunct routing command whose adjunct link is down, the wait-time step is 
skipped.  Step 3 contains another 
adjunct routing command whose...

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 d own [the

Accordingly, you should almost always include either a wait-time step or an 
announcement step immediately after an adjunct routing step. Moreover, the 
switch cancels the route request if vector processing encounters a step 
containing one of the following commands:
nadjunct routing (G3V2 and earlier releases.) G3V3 and later releases allow 
multiple outstanding adjunct route requests.

judgement should be used in  determining which of the treatment commands is 
best for the particular ap p lication.
Finally, note that the adjunct can also decide to not route a call by rejecting (that 
is, negatively acknowledging) the route request sent by the switch.  Upon 
receiving a route request rejection, the switch terminates the 
announcement or 
wait-time step that is being executed for the call and then continues with the next 
vector step....

NOTE:
The o peration described in the previous paragraph is similar to that for the 
route-to with coverage command.
Multiple Outstanding Route Requests
This feature allows multiple ASAI  Route Requests for the same call to be active 
at the same time (simultaneously). The Route Requests can be over the same or 
different ASAI links.
The requests are all made from the same vector. They must be specified back-
to-back, without intermediate (
wait-time,...

User Scenarios
Figure 9-5 shows a typical vector where multiple adjunct route requests  to 
multiple links will be active at the same time. The first adjunct to route the call is 
the active adjunct (that is, it specifies which VDN the call should be route d to at 
that point).
