You should look into the TEKELEC Chameleon.  Not only can you write
simulation software, but you can buy already written software from them.
You can analyze, simulate, and even save/replay old protocol
scenerios, to see if you have fixed a bug correctly.
There's X.25 certification software, a BSC test package,
plus SNA test software.  It costs about $20K.
Our Rochester NY division used it to develop both X.25 and SNA,
plus port a version of BSC to our machines.  A co-worker has said
that the machine is incredibly powerful, however, I have not had
much first hand experience with using it.
