Call Scenarios and Applications
Issue 7 March 1998
A-49
External Call to a VDN that has a Converse Step
that is not Interrupted
This scenario presents the call flow for an incoming ISDN PRI call for VDN 7001
that has a converse vector command that is not interrupted (see Figure A-11). The
converse vector command passes both the ANI and the VDN number to the VRU.
The VRU, after completing the session with the caller, sends the call back to
vector processing. Along with sending the call back, the VRU also sends data
back to the DEFINITY ECS. This data is collected in a collected digits step. An
adjunct route is then done that sends these collected digits to the ASAI Adjunct
Processor. The ASAI Adjunct Processor then routes the call to ACD Split 3456.
Note that in this scenario, vector processing requires the caller to complete the
interaction with the VRU before any additional processing is done to the call.
Furthermore, the Alerting Event Report sent when the call alerts the VRU port
contains a cause value — CS3/23 (remains in queue). This is to inform the ASAI
Adjunct Processor that this is a converse split.
VDN 7001 has Event Notification active and each port on the VRU has Domain
Control active.
