FCC workshop participants: Interconnection critical to PSTN phase-out
Before the traditional phone network can be phased out, steps should be taken to ensure that the networks replacing it are interoperable, said several stakeholders who participated in a Federal Communications Commission workshop convened to explore issues associated with a public switched telephone network (PSTN) phase-out -- an idea floated by AT&T a couple of years ago that is now gaining momentum.
Ensuring interoperability is no easy task, considering that the tightly integrated and monolithic phone network of yesteryear has been gradually transitioning to a more competitive and fragmented marketplace. Walter Johnson of the FCC’s Office of Engineering and Technology framed the issue in a question at yesterday’s workshop. “How do [we] create a common language when so many [parties] bring a piece of the solution to the table?” he asked. “This is the critical question,” answered Harold Feld of consumer group Public Knowledge. “It starts with interconnection.”
