The problem with searching for "Erlang" in connection with telecoms is
Agner Krarup Erlang and the erlang unit, not to mention several companies
named after them.

However, the 1.7m SLOC and 31 ms downtime per year figures are for the
AXD 301 ATM switch, which is much easier to search on -- for example see
<http://www.ericsson.com/ericsson/press/archive/1999Q4/19991012-0501.html>

The whole UK telephone system of course involves much more code than that
switch.
