Shutting the phone network off while you’re running out of internet protocol numbers

I ended 2011 with a short (20 December) visit to a pleasantly warm Washington, D.C. for my 5th FCC Technical Advisory Council meeting. Some of the discussions from the third meeting were extended, others cut off for lack of time. We spent over an hour on the suggestion made by the Legacy Transition working group two meetings ago to advise the FCC to move forward in sunsetting (although we shunned that term at this meeting — “It’s a new beginning, not an end!”) the public-switched telephone network (PSTN). Many questions have arisen repeatedly in the discussions over the course of the last two meetings (and two FCC workshops in between), notably, “What happens to the telephony numbering system?” The initial strategy was imprecise, “The numbering plan will continue to exist but governance and allocation process needs to be considered.” Another repeated question has been “What exactly do we mean by PSTN?”
