# Externally Initiated “Fire and Forget” to TD or TS Queue

The externally initiated “fire and forget” to TD or TS queue shares the same architecture for the preceding scenarios, except that the inbound data is written to a CICS TS or TD queue. The TD queues can be local to that AOR or shared with another AOR.

The following figure shows the externally initiated “fire and forget” to TD or TS queue scenario:

You can create a dual-purpose definition of that resource in a Circuit Switch Data (CSD) file that is shared by the local and remote systems. Such a step reduces disk storage and maintenance, because only one CSD file record is required for each shared resource.
