 Be sure to read the section **Advanced Message Matching** in [[Message Matching]] concerning Repeat and Optional before using this approach, but when required it can be a powerful tool.
+**Characterization**
+An alternative to the above approach to listing ECIDs is to use the characterization capabilities of TransSECS.
+Characterization provides a list of all CEIDs, Reports (RPTIDs) and VIDs (SVIDs and ECIDs) available on the tool.  Simply call the "characterize" method with the host controller.
+<code java>
+Characterize.characterize(host);
+</code>
+This will populate the GEM Host Model maintained by the host. This can be retrieved with the call:
+<code java>
+host.getGemHostModel();
+</code>
+Check the GemHostModel JavaDocs for details of the model.
