Minot Phone Book 1958 #2

Dial Service Instructions – One of the first pages in the 1958 telephone directory had a complete set of instructions on how to use a rotary dial telephone. I believe this was about the time the dial phones came into existence. The instructions also explained the different signals one could hear over the phone lines…. The phone ringing signal was described as a “burring” sound…. The Busy signal a “buzz-buzz-buzz” sound.  Instructions were also there on the use of “party lines”. Long distance and out of town calls had to go through the operator. In 1958 all phone numbers were 5 digit. Example: the phone number for Steenstrup Jewelers was 36-221
