Not a telephone central office building per se. This ratecenter is so small that a small cabinet based remote switch is all that's needed. There is another similar cabinet about a mile away that has a FairPoint logo on it but didn't stop to take a picture of it. Hancock is one of only three ratecenters in MA served by an independent telephone company.
