Wawina has the distinction of having America's smallest telephone company. Northern Telephone Company of Minnesota (Area Code 218–488) serves fewer than 40 subscribers. It gained brief fame as the last place in the continental United States to use a trunking system (inter-office circuits) that was called "N2 Carrier", an analog system that utilized Multi-Frequency (MF) tones and the infamous
2600 Hz control tone for answer supervision and idle trunk condition. This system was much loved by phone
phreaks as it was the same system which the now infamous
John Draper made famous. The era ended in June 2006, when the privately owned exchange switched to a digital trunk. Phone hacking attempts from across the nation had placed a large burden on the extremely small telephone company serving Wawina Township. ==References==
