Purpose of the TCH connector component

The TCH connector component provides all functions that are required to interface with the TCH test and TCH production environments.

The component works on the same interfaces that are provided by the FTM for Immediate Payments TCH CSM simulator with all capabilities that are required to connect to TCH, especially from a networking, IBM® MQ, and security point of view. While you can test and extend the FTM for Immediate Payments application using the supplied simulators for those interfaces, you can switch at any point in time to use the TCH system after you are ready for running the systems end-to-end.

The key functions of the TCH connector component are:
  • System administration and notification messages:
    • Sending sign-on, sign-off, and echo requests.
    • Automatic sign-on for "always active configurations".
  • Processing and forwarding payment messages:
    • Message signature generation and validation.
    • Exchange messages with FTM for Immediate Payments.
    • Correlate responses from FTM for Immediate Payments with the originating TCH RTPS instance.
  • Processing of system notification messages that are received from TCH:
    • Support for IBM MQ publishing and subscribing. Allows any application to subscribe to RTPS notifications.
    • Optionally store system notification messages in log files.
  • Monitoring, logging, and tracing:
    • Provide all insight to operational staff on the message exchange with RTPS.
    • Supports IBM App Connect Enterprise data capture user interface
    • Supports logging for all failures and connection states
    • Supports tracing with different levels of details
    • Integration with IBM App Connect Enterprise data capture database and console
  • Support of HA and Failover scenarios in an Active-Active or Active-Passive TCH configuration.
    • Active-Active: 2 TCH connectors running in parallel on each operation site
    • Active-Passive: 2 TCH connectors running either on the primary or backup operation site
