A good place to start might be the POTS control program, which was
presented in the Erlang book, and also used (in a slightly different form)
in the Introductory Erlang course.

I used it in my "Structured Network Programming" presentation to
show the consequences of different programming styles in multiway
signaling:

I'm not convinced that it will be sufficient to reveal significant differences
between the standard erlang style and channels, but it's a good place to
start, and the code can be expanded in a number of interesting ways.

(There's a working simulator to go with the program, but the OTP team
would have to give permission to release it in public. I'm sure you can
get your hands on it anyway.)
