The two test data files presented here for unit testing of RAA' function are: d144-ul-input.asc This file is generated in Themyscira gsm-net-reveng Hg repository, d144 subdirectory. The original hand-crafted input is a different file in the same directory (ul-input); the present *.asc file is the output of some helper programs maintained in the same place, reformatted to be more directly suitable as a unit test for libosmotrau RAA' encoding functions. nokia-tcsm2-atrau.hex This file is the A-interface output from a historical hardware TRAU (Nokia TCSM2) whose input was the sequence of 290-bit "user" frames in d144-ul-input.asc. It is raw E1 timeslot output that has been extracted in perfect alignment and converted into hexadecimal representation, with 80 hex digits per line. A correct RAA' encoder implementation should produce output identical to nokia-tcsm2-atrau.hex when fed with d144-ul-input.asc, and vice-versa for a correct RAA' decoder implementation.
