Regional bell telephone companies around the country are in the process of phasing out all antiquated copper wire networks to be replaced by fiber optic cables to the home.
Only 16 years ago In 2000, almost every U.S. household had a landline phone. Since then, many have dropped landline service in favor of cell phones as a primary number, and nearly 50 million of the remaining lines have switched to Voice over IP, which sends voice calls in the user's broadband data stream rather than over traditional telephony’s copper wire pairs.
For one thing, this change will make the old DSL (digital subscriber lines) obsolete because there will be no need to compromise with the limitations of copper. FCC chairman Tom Wheeler and others have been pushing to shift telephone traffic to fiber optics and the Internet.
