Could PSTN Go Away By 2018? 305

Posted by timothy
from the hullo-operator dept.
An anonymous reader writes "If current rates hold, only 6% of the U.S. population will still be served by the public switched telephone network by the end of 2018. Tom Evslin reports that the 'Technical Advisory Council (TAC) to the Federal Communications Commission (FCC) recommended last week that the FCC set a date certain for the sunset of the PSTN rather than let the service fade slowly into oblivion as it is doing now.' Since doing 'nothing' isn't really possible, he suggests: (possibly) end(ing) the Universal Service Fund subsidies, ensuring PSTN-dependent services like E911 work on new technologies, and assuring that everyone who now has PSTN service has access to either a broadband or cellular communication alternative."

    As someone who's programmed PSTN, it's really not needed anymore. It's so inefficient it's not funny. Both ISDN & PSTN are so archaic now that there's no logical way to justify keeping these technologies going. It's why I don't understand opposition to the NBN here in Australia.

      Wireless ethernet backhaul - need towers

      Nobody. The copper will be pulled out and sold for scrap. And if you aren't really careful, the roving gangs of copper thieves will beat you to it and sell your copper even before the service ends.

      Goodbye DSL. It will not exist any longer. And no, the government isn't going to decide to spend billions on putting fiber in to every home. Verizon is already doing it and Qwest is getting started. Unfortunately, they might stop or really slow down if there is no more revenue from landline service.

    Here's a potentially stupid question.

    My family's gone cellular; we only have a landline for DSL. Last night we had a power outage in my part of Philadelphia. Not too bad, perhaps 20 minutes or so, but the outage apparently also took out the cell my phone connects to. As I recall, the PSTN works even if the rest of the grid is down. So what happens if, during an outage that also eliminates cellular connectivity, someone has, say, a medical emergency? With wireline redundancy on a separate system, I can call 911 and get an ambulance to my location in a hurry. Without it, I'm SOL.

    The question, therefore, is: How do we mitigate the risk that some related service interruption leaves us completely disconnected at a moment of crisis?

      Let's now be silly here. PSTN operates on a separate grid + backup power basis so that it works even in the case of a (normal) power cut. There's no reason that cellular or broadband networks can't be required to do the same and/or don't already do that.

      I've never experienced a cellular "outage" except through something other than simple power - i.e. oversubscribed networks, busy periods (e.g. New Year Eve), or just plain stupidity of someone changing settings they shouldn't. So there's nothing to say that the cellular network isn't already backed in terms of additional / temporary / emergency power.

      It's like saying what would have happened during a PSTN outage even if the normal grid wasn't affected? Same problem, and would have happened just as often (PSTN networks aren't somehow infallible, and sometimes HAVE to be shutdown for safety reasons if they are still supplying power to places that could be dangerous - e.g. fires, gas leaks, etc.). All that happens is that instead of PSTN you use cellular, or broadband (which is still essentially running on the same PSTN copper/street cabinets/exchanges).

      The only "problem" is that cellular isn't a guaranteed service in that it could be up and running but far too busy to let you call rather than, say, the emergency services. Although they have a QoS for such emergency services, you won't necessarily be able to get signal in an emergency purely because of the sheer number of people near you trying to do the same. But broadband? That's a different matter.

      PSTN was just "a" network. What did you do before you had cellular and there was an accident? You relied on PSTN or "something else" (i.e. your neighbours PSTN, or CB radio, or whatever). Now you just shift your expectations and use other methods.

      To be honest, in an urban environment, I've never had quite so many completely independent ways of contacting people in an emergency. The loss of one, albeit one of the most reliable, is hardly a loss at all in terms of safety. There are at least three different methods of Internet connection available to me just sitting at home - cable internet, phone-line-based internet (e.g. ADSL, etc.) and 3G internet. They are all more-or-less independent of each other so if the 3G goes down, SOMETHING else will work and if the ADSL goes down, I can always hook up a 3G dongle (on any of 5 major networks that all run seperate infrastructure and frequencies).

      If I was out in the sticks, I'd be slightly more worried but your basic landline phone isn't going away - it's just changing its underlying technology. There's still plenty of options open to anyone that needs them. It's not like it's the 40's anymore where the next phone is several miles away and you have no other backups at all.

        The POTS system has had a hundred years of experience to work out issues like redundant power supplies. Cellular networks haven't. So POTS often works when cell doesn't; the reverse is almost never true.

    • That seems odd. When the power went out to Northern Alabama for nearly a week in April it took almost 24 hours for the cell towers to start dying. They have pretty substantial battery backups. Within 12 hours or so of the towers starting to die, someone from AT&T seemed to realize that the power wasn't coming back anytime soon; and they either set up a battery rotation schedule or put generators on the towers. All in all the system was only really dead for about 12-14 hours of the week long outage.

  • I don't know about the US, but with the completion of the NBN [wikipedia.org] in Australia the PSTN will be history here.

    History means all copper land lines gone and all the analogue gear the copper is connected to in the 1200 exchanges becomes land fill, along with all the ISDN based switch gear. The 1200 exchanges will be reduced to 120 point of interconnects. We are talking scorched earth here.

    (Disclaimer: I work for a landline company)

    You are assuming that 'everyone' wants this, including retirees, people in rural areas, people who just don't need broadband and know it. You assume that the cellular/VoIP offerings will be as robust as the PSTN. You also assume that, if the landline business is 'dissolved', these other networks can take over the load.

    Do you know who connects those cell towers? Those towers don't talk to each other wirelessly, they use terrestrial copper/fiber. If you sunset the network that keeps the copper/fiber infrastructure in reasonably good shape, the economics of maintaining the cellular network change, driving up costs significantly.

    And please, don't maintain that there is quality parity between these types of services/networks: I have had so many conversations with business owners who tried using VoIP-based services for their dialtone and came running back to the PSTN because their customers complained about voice quality and dropped calls. Also note that while many government agencies have adopted VoIP internally, they recognize that they must have a reliable network to serve the public, especially for emergency services, and thus the vast majority stick with the PSTN for dialtone.

    The PSTN and the Internet are both great networks, but they were built on different premises and with different (internal) priorities. One is really good at low-latency communications, one is very good at network survivability.

    I'm not a Luddite suggesting that we throw away new technologies, but I'm also not some knee-jerk hype-meister of What's Hot Now. Both networks have their place and will coexist for many years to come.

  • So, they want to shut down the PSTN in favor of cellular service?

    What the FUCK do these dimwit politicians think is the mechanism that actually transmits their cellular call after it leaves the NSS? Magic and unicorn farts?? Or are they just in bed with the broadband/cable television companies who want to see even more critical consumer data pushed across their cheap last mile infrastructure so they can append it to people's data caps?

    That's fine, but first the wireless and broadband carriers must be made common carriers like they are over telephone. That is one of the biggest differences between the systems. Telephone companies are not permitted to delay, degrade, alter, or record telephone conversations or modem signals. But no such protections exist over broadband or wireless. They have no requirements for call quality, nothing stops them from inserted advertisements or charging you differently depending on who you call.

    Those same protections need to apply to other services, in addition to deregulating them so we have choices.

  • Could PSTN Go Away By 2018?

    I read that as "Could the PSN go away by 2018...". I was thinking: "Only if the script kiddies hit puberty!"

    Why is doing nothing never an option for federal bureaucRATS? If the service was really that bad, wouldn't the last few customers just stop using it completely? I guess then the cronies wouldn't be able to stick their greasy paws into every aspect of our lives. I am convinced that these FCC jobs are nothing but expensive busywork for the buddies of our elected officials. Nothing they do makes any logical sense.

    Some Congresscritter will come up with the idea of making everyone with cell phones, VoIP, and broadband connections pay even more to subsidize the dwindling number of PSTN users.

  • I dumped PSTN somewhere around 2002, first went to vonage and shortly after to Asterisk + PSTN gateways. Over these 9 years I think I've developed an idea of the pros and cons of VOIP.

    * Call quality, on average, has been very good. This probably depends mostly on one's ISP, but call quality is better than a cell phone which most people are OK with. I prefer PCMU since it's what the telcos use and is a simple (little processing overhead) and raw codec. Keep in mind that it's possible to use codecs with h

  • " and assuring that everyone who now has PSTN service has access to either a broadband or cellular communication alternative"

    What country does this guy live in? There are still areas (MANY areas)  in the US that are either only served by PSTN or satellite. I'd personally rather use dialup than satellite especially for the work I do in a shell (insane ping times on satellite...)
  • Last I knew, the FCC didn't run the PSTN -- they just regulated common carriers (the providers of the PSTN to consumers). They don't have the authority to shut it down, nor would they save any money doing so. All they do is regulate the carriers, approve interconnection agreements, and make skewed reports on its use.

    What is also neglected here is two major things :
    - The cellular network runs over the PSTN. Without the PSTN backbone, cellular calls would not be able to be connected to people outsi

  • I live in southern California. My electrical service is Southern California Edison (SoCalEd), which can have outages any time of the year.

    My broadband service is through Time Warner Cable TV. When SoCalEd fails, Time Warner's amplifiers die, leaving me with no Internet, no VOIP, and (if I had it) no Time Warner phone service.

    I don't have a cell phone, but my wife does. When SoCalEd fails, the local cell towers die.

    However, my phone service is land-line (PSTN) through AT&T. This phone service is self

  • ... when the replacement has the reliability of PSTN. At a minimum, the battery backup for the fiber box in my house must run longer than the worst-case power outage in my area.

    I could switch to FIOS right now, and they'd give me an interface box they claim is good for up to 12 hours.

    I live in the Washington DC metro area. Neighborhoods in this area have lost power for DAYS within the past few years.

    The migration of individuals from landline service to cell only insures that at some point there just isn't going to be enough revenue to keep the infrastructure maintained. So the maintainers are going to want to pull the plug and will start lobbying for that... like it seems they have already.

    First casuality will be DSL. It requires really good copper connections to the CO and they are going to degrade. Even if they don't pull the copper out and leave the CO as a unmaintained building the lines will degrade enough to doom any possibility of DSL in a short period of time. So if you don't have cable now, you might want to look into it REAL SOON.

    Second thing is people will notice that cell phone service isn't tariffed like landlines are. The operating companies are required to have pretty much 100% up time, or so close as to not make any difference. Cell towers are not required to be up. Cell towers are not on large building-size battery banks and do not have backup generators like every CO is required to have. So when there is a power outage, the tower is down until power is restored. Yes, there are UPSs in place to hold the tower service up over short outages, but we are talking seconds or maybe at most minutes not hours or days. Might want to think about that and lobby for getting cell service upgraded from being a luxury to being tariffed like landline phone service is today.

    It sounds really nice that the Australian government is taking over the last mile connections. It isn't going to happen in the US for a couple of reasons. The first one is can you imagine the response to spending 3-4 hundred billion on such a project today? No, sorry, it would not be approved as the money simply isn't there. Then there is the idea that the government would be actively supporting and facilitating child porn, porn of all sorts, etc. etc. etc. Someone would notice in a big way. You might be able to pass that off in some other places, but I don't think it would fly here. I can see it now where someone fights a child porn charge by having someone testify that the government provided their Internet connection and did not filter it to ensure that child porn could not be viewed. This then constitutes permission and facilitation.

    The private companies that are today running fiber are in large part still supported by landline phone service. It may be a declining part of their revenue, but it is still there. Should that revenue disappear - as is seems certain to do so - why would they continue wiring the world when their remaining revenue is from wireless services almost exclusively? Verizon and Qwest (the two that I know of with fiber programs) could drop all landline services, get rid of the thousands of trucks and wireline-servicing employees and focus only on wireless pretty easily. It would be a consolidation and focusing of attention, both things that are good for businesses. They would likely benefit greatly from increased efficiency - translated as revenue per employee. Oh, did I say that if you didn't have cable you might want to think about it?
