PSTN-to-IP transition

[Commentary] Federal Communications Commission Chairman Ajit Pai is setting a record pace for deregulating the communications industries. Believe it or not, things are about to get worse in Nov. Starting with the FCC’s open meeting on Nov 16, the agency is poised to approve or propose no fewer than four decisions that will deregulate consolidated industries, remove consumer protections, and widen the digital divide:

Sooner rather than later, landline telephone service will completely transition to wireless and Internet-based calling (commonly referred to as Voice Over the Internet Protocol or "VoIP").  While the Federal Communications Commission, for over a decade, has precluded a “flash cut” service termination, I expect the timeline for copper wire service retirements to shorten.

In rural areas, many large internet service providers (ISP) offer voice-over-IP. Nathan Smith, Director of Economics and Policy at Connected Nation said, “It’s likely that a lot of [Broadband Equity, Access, and Deployment (BEAD)] sub-grantees will add voice for an additional revenue stream." However, the BEAD Notice of Funding Opportunity does not require grant applicants to offer voice service, though the actual grants will be made by state governments who set their own rules. Ciena’s Solutions Marketing Senior Adviser Vinicius Santos expects some state broadband offices to ask applicants

The Public Switched Telephone Network (PSTN) network has been used for interconnection to the local incumbent offices and tandem switches, for connecting to 911 centers, for connecting to operator services, for connecting to cellular carriers, or for connecting to other neighboring carriers. We are finally starting to see that network being shut down, route by route and piece by piece. But like everything related to operating in the regulated legacy world, it’s not easy to disconnect the PSTN connections called trunks.

Frontier Communications still has hundreds of thousands of copper passings, but it doesn’t seem like that footprint will be taken offline anytime soon.

During a hearing titled "Building Resilient Networks," lawmakers on the Senate Commerce Committee's Subcommittee on Communications, Media, and Broadband were asked to boost the reliability of the nation's broadband networks by spreading infrastructure funding among a variety of technologies such as fixed wireless and mobile broadband rather than limiting it solely to fiber. Wireless Infrastructure Association President Jonathan Adelstein testified that a singular focus on fiber broadband networks that can deliver "symmetrical" speeds of 100 megabits per second would prioritize a sometimes c

AT&T and Frontier have let their copper phone networks deteriorate through neglect since 2010, resulting in poor service quality and many lengthy outages, a report commissioned by the California state government found. Customers in low-income areas and areas without substantial competition have fared the worst, the report found. AT&T in particular was found to have neglected low-income communities and to have imposed severe price increases adding up to 152.6 percent over a decade.

Network reliability and network resiliency are distinct concepts that are inextricably linked. “Network reliability” means that you can rely on the fact that you will have phone service to make and receive phone calls and text messages. As an example, a network can become unreliable from a lack of network maintenance that leads to total degradation, or a lack of preparation to handle technological failure.

USTelecom released its Industry Metrics and Trends 2020 report highlighting key elements of the broadband boom and investment story. USTelecom will weigh in soon explaining why the Federal Communications Commission should no longer mandate so-called network unbundling, a relic from a different (and far less competitive) era. Key highlights from the USTelecom Industry Metrics and Trends 2020:

Consumers and providers have made the transition from legacy voice to broadband and mobile communications services.

The 9th U.S. Circuit Court of Appeals denied a legal challenge from Public Knowledge, The Greenlining Institute and other groups to Federal Communications Commission Chairman Ajit Pai’s 2017 rollback of certain Obama-era requirements for phone companies angling to transition off of legacy copper networks. “This is a victory for American consumers, who will benefit from faster fiber deployment and the increased availability of next-generation services,” Chairman Pai said. He has touted the deregulation as critical for allowing the transition to more advanced, IP-based networks.
