The telephone company provides for you a dialtone from the global telephone network. The wire carrying your dialtone will be attached to your home directly to the demarc. Demarch or Dmarc is short for "demarcation point" which is the point where the telephone company network ends and connects with the wiring at the customer premises. You may find the demarc on the inside or outside of your home or business.
