At the EUC2001, I spoke about implementing one relatively simple layer
of the #7 stack, MTP-2. Other (higher) layers of the #7 stack are
considerably more complex. Some of our customers have their own #7
stacks which they attach to our system at the MTP-2/MTP-3 interface,
but they're not Erlang.
There was an effort at the Ericsson computer science laboratory to
implement #7 in Erlang. I believe MTP-3, TCAP and SCCP were all "90%
finished". The other 90% of the work was never completed, the main
protagonists were sidetracked, first by inventing the binary syntax
and then by the .com bubble.
In any case, as far as I know, nobody has implemented a complete #7
stack (e.g. everything up to GSM-MAP) in Erlang. It seems like quite a
do-able project, albeit rather daunting for just one person.
