Why is operation over both phone wire and coax cable important?
Operation over coax and phone wire can lower installation costs by allowing every coax and phone jack to be a potential network connection. Cable adoption in the home is far from universal, while almost every home and MDU in America and much of the rest of the world has phone wires installed. In addition, the coax installed in an MDU may be the property of the building’s owner who already has a contract to provide TV services. Operation over phone wire can provide a service provider with an alternate means of access to customers who live in MDUs.
