Indeed there are several. These include Ericsson's ATM switch
(about 700 000 lines of source code) and a special purpose PABX
(5000 000 lines of code). But don't get the idea that Erlang is
useful only for telecom products, Erlang has been used for a wide
variety of applications. On avaerage the total time required to
build products is about a quarter or the time used when a more
conventional approach is used. this is both because of Erlang and
because of the incremental design approach it allows

Good enough for our extremely time critical telecoms
applications!
