Tom,

   Interesting history and somewhat clear (to me) explanation.

   When the 971 overlay to area code 503 went into effect 7-digit dialing
died. All calls require the area code even if you call your 503- cell phone
from your 503- land line in the same house.

   So, if all calls are treated the same, as digital data, why can some
really local numbers be dialed without the 1 prefix?
