+\section adsi_tests_page_sec_1 What does it do?
+These tests exercise the ADSI module, for all supported standards. A transmit
+and a receive instance of the ADSI module are connected together. A quantity
+of messages is passed between these instances, and checked for accuracy at
+the receiver. Since the FSK modems used for this are exercised fully by other
+tests, these tests do not include line modelling.
+
+\section adsi_tests_page_sec_2 How does it work?
