Not very likely with today's technology. Before 1985, if a territory that had not had phone service in the past suddenly started getting settled and there was a lot of demand for phone service, a phone company typically would file to offer service in that area, and once granted, that phone company would run copper and build a CO.
Today, such an area would typically get a remote terminal or a VRAD, depending on the entity offering service. Or perhaps just a wireless offering, if the area was large.
Most definitely in the areas where service is already offered, the telcos won't build any new COs. They'll use the existing outside plant to continue offering traditional voice service (unless SB 1161 gets rammed through without any amendments), and they'll install remote terminals and/or VRADs to extend digital services to the areas where they believe the demand for digital service will provide sufficient ROI.
