An ASx Issuer Solution with External Fraud Detection
In this example, the ASx solution is once again installed in two
locations, connected by dual TCP/IP Wans. ASx could either be configured in load-sharing
mode or in primary/secondary mode. The network management will be responsible for
routing transaction messages arriving from the networks to the appropriate ASx for
processing. There are various ways to achieve this depending upon the mode of operation
required. As always, the important point is that one ASx will take the load of another
immediately when a failure occurs.
For redundancy, there are twin Visa, MasterCard and domestic interchange access
points. Additionally, there are two connections to the external fraud detection
or management solution. ASx will pass either pre or post-authorization data to the
fraud management system and is capable of receiving transaction rules fed directly
from that system. Those rules shall be used for future transactions and may be applied
to a single card, single account or to multiple card and account ranges. For more
information on these features, please select the ASx Fraud Detection option from
the side menu.

HotSync® is used to maintain the integrity of the data used by both ASx systems
running at the two locations.
Not-on-us transactions received from the domestic interface shall be routed to the
Visa or MasterCard networks for processing. On-us transactions originating from
any network shall be processed directly by ASx.
ASx provides the required settlement for the domestic interface. ASx provides Visa
Base 2 and MasterCard ECCF/ICF clearing interfaces as standard.
