Look-Ahead Interflow
8-4Issue  4  September 1995
Here’s an example of an outflow vector that might be included in a sending 
switch:
Figure 8-2. Sending Switch Outflow Vector
If split 3 has staffe d agents, and if there are 30 or fewer calls queued to the sp lit, 
Step 3 queues the call to the split’s queue at a medium priority. In Ste p 4, an 
announcement that apologizes for the delay is provided. Vector processing then 
continues at Step 5, where music is provided for 20 seconds (Step 5). If the call...

Once inflow checking is complete, acceptance of the Look-Ahead Interflow call 
is accomplished by executing any of the vector commands presented in the 
following table:
NOTE:
For each command in the next three tables, only one of the corresp onding 
qualifications need be true for the command to effect the d esired result 
(call acceptance,...

If the receiving switch decides it is unable to accept the Look-Ahead Interflow 
call, call denial is accomplished by executing either of the vector commands 
listed in the following table. One recommendation: use 
busy instead of 
disconnect to allow for compatibility with similar network services such as ADR.
The vector commands presented in the next table are considered neutral 
because they do not generate either call acceptance or denial messages....

The following is an example of an inflow vector that might b e used by a receiving 
switch:
Figure 8-3. Receiving Switch Inflow Vector
Step 1 of this inflow vector checks the inflow thresholds. The 
g oto step command 
in Step 1 chec ks the number of queued calls in split 1. If the number of such calls 
is greater than 5, a branch is made to the 
busy command in Step 6. If executed, 
the 
busy command denies the call, and the receiving switch returns a...

Figure 8-4. LAI Using a Tandem Switch
Sending Switch Operation
The sending switch is unaware that its Look-Ahead Interflow call is being 
tandemed to an alternate switch. The operation of the sending switch in the 
tandem switch configuration is the same as that in the two switch configuration.
Tandem Switch Operation
If the receiving switch executes a route-to command that routes the call over an 
ISDN facility b efore call acceptance, the 
route-to...

Step 1 of this vector checks the inflow threshold. If the inflow criteria are 
acceptable, the vector flow drops to Step 2, where the 
queue-to main sp lit 
command provides acceptance to the sending switch. Thereafter, Steps 3 
through 5 provide a typ ical queuing-wait scheme.
If, however, the inflow criteria are not acceptable, a branch is made to Step 6. 
The 
route-to command in this step checks another switch enabled with Look-
Ahead Interflow on...

The type of DNIS information that is displayed depends upon a number of

NOTE:
VDNs that map to vectors that place Look-Ahead Interflow calls must have 
their ISDN Calling Party Number (CPN) prefixes administered. If an ISDN 
CPN p refix is not administered, the assigned VDN name is not sent, instead 
a DNIS of all blank s pace...

Look-Ahead Interflow with AT&T Network
Alternate Destination Redirection (ADR)
Call Vectoring and Look-Ahead Interflow are compatible with and supplement 
the AT&T network services Alternate Destination Redirection (ADR) rerouting 
feature. ADR uses ISDN-PRI connectivity with the customer-premises PBX/ACD 
in the same manner as Look-Ahead Interflow to allow the receiving PBX/ACD to 
indicate whether a call is to  be accepted or rejected. The same type...
