    Obviously, the thing to do is to contact a specialist at a company like Globalstar and tell them what you're trying to achieve, as cost-effectively as possible. They deal with this sort of thing all the time.
    Actually you did point out satphones as a redundancy resource, I was just mentioning how much they've come down in price lately.

    I don't think that wired telephone service for homes and businesses will be replaced by wireless anytime soon, but I do think that the way that wired service is provided to your premises is changing rapidly.

    Old-time telephone service (POTS) used a hardwired copper pair between your phone and the telephone company's central office. Your phone was powered by a bank of batteries located at the central office. The simplicity of this technology was what made it rock solid and very reliable, even in times of extended power outages.

    Today, your home phone service may look and act like POTS, but it may be something else entirely. A good example is the telephone service provided by the cable companies, which consists of a multiplexed signal which is run up and down the broadband cable network and decoded when it gets to your house.

    Also, many homes and businesses are now using voice over internet (VOIP) systems which use a fiber optic network connection rather than traditional phone lines to carry telephone signals. These systems are often configured to look like POTS on both ends to enable the use of legacy telephone equipment. The user may think he has POTS, but he really doesn't.

    Cable, fiber optic, and VOIP systems typically require lots of complicated electronic equipment along the cable pathway to your home or business. Most of this equipment is installed on poles or in cabinets along the roadway and needs local power to
    operate. Because of the added complexity of these systems, they are inherently less reliable than traditional POTS in my opinion.

    (Possibly the rantings of an old man who can't accept change.... )

And I'm not just talking about rural areas either. You can't get a decent signal half the time in DOWNTOWN MANHATTAN! (Check out the Sprint, Verizon and T-Mobile complaint forums if you don't believe me! The service capability of the carriers still lags way, way behind the capability of the phones.)

    So, my friend, you've spent a lot of time and effort to prove nothing. Regardless, I don't intend to get into a food fight with you when it comes to "future predictions" about cellular, particularly in the United States, which have traditionally been grandiose and way off the mark.
    I wholeheartedly agree they are not anywhere near the reliability of the good old land line. My point is if the FCC wants them gone like analog TV, They will be gone. When ATT and the FCC are talking about setting dates. When ATT is shutting down POTS systems converting them to VOIP right and left. Cable companies are getting into phone and cellular. Then hoopla starts about VOIP vs POTS, who are you going to believe? Is it another Y2K scare? Or are you going to just be SOL some day in the future? Now when congress gets involved to mandate nationwide broadband in their stimulous bill. It's coming. I dont like it . I don't want it. but...

    No food fight here, especially about cellular.

    The following article also compares the TV to telephone connection. Excuse the pun.


    POTS sunset on the horizon?

    Daniel Gelinas - Jan 07, 2010 Add date:
    Jan 07, 2010


    WASHINGTON--Plain-old telephone service--the mainspring of traditional burg and fire alarm signal transmission--could be coming to a mandatory end. The Federal Communications Commission on Dec. 1 issued a public notice seeking comment on a National Broadband Plan that could include a mandatory switch from a public switched telephone network to IP, similar to the FCC-enforced switch from analog to digital broadcast television that occurred in early 2009.
    FCC spokesman Mark Wigfield said while nothing had been decided, the FCC needed to collect as much information as possible about how such a nationwide switch over should be approached and what effect it would have. "There was a requirement in the stimulus bill that the FCC develop a National Broadband Plan for Congress within a year," Wigfield said. "Part of the question about going from circuit switch to IP is ... can you maybe align the incentives for investment and government incentives better if there's an IP network rather than this bifurcated circuit switch phone service? So we're looking at what these issues are and what it would take to make that switch."

    In a Dec. 21 filing from AT&T to the FCC, the telecommunications giant claimed the switchover is not only necessary, but is already an inevitable and accelerating process. "With each passing day, more and more communications services migrate to broadband and IP-based services, leaving the public switched telephone network ('PSTN') and plain-old telephone service ('POTS') as relics of a by-gone era," the filing reads. "The Commission has been charged by Congress with formulating a National Broadband Plan that will result in broadband availability for 100 percent of the United States. That auspicious goal is within reach, but only if the Commission marshals its resources and those of other stakeholders to develop and execute a strategy ... A key component of that strategy is the orderly transition away from, and retirement of, the PSTN." The AT&T document further claims that currently "less than 20 percent of Americans rely exclusively on POTS for voice service. Approximately 25 percent of households have abandoned POTS altogether, and another 700,000 lines are being cut every month."



    AT&T in a June 2009 press release suggested a deadline of 2014.

    AT&T Tells FCC It's Time to Cut the Cord

    By Tony Bradley, PCWorld
    In response to a Notice of Inquiry released by the FCC to explore how to transition to a purely IP-based communications network, AT&T has declared that it's time to cut the cord. AT&T told the FCC that the death of landlines is a matter of when , not if, and asked that a firm deadline be set for pulling the plug.

    Being primarily commercial we are going full data link cellular as primary but that technology is going away too being "upgraded". When the G's settle down a few years, we will decide upon which to focus on. Henceforth we have been toting the triple whammy. POTS, cellular and IP. All three for one money.

    Furthermore, there are still vast areas where it's going to be at least a decade before towers get built. Almost all of these areas are being served by landlines.

    POTS lines are going away. ATT reports cutting 700,000 per month since 2009. They estimate in 2014. they will be gone.

    The twenty bucks is going to be cheap redundancy for awhile - and you can always drop it when/if the line "goes away" and/or wireless service gets so good that you can bet your life on it.

    After yesterday's bus bombing in Jerusalem, all cell phones in the area were simply shut down. The police do this to prevent cell phone triggered secondary devices from taking out first responders.

    My grandfather, aunt, and three cousins were all in the bus station at the time, but they had to get to a pay phone to call my parents and tell them they were okay (my parents are in Israel for my cousin's wedding).

    Honestly, I don't even have a land line at home. My wife and I both have cell phones, I just can't see the utility in spending the... twenty bucks a month? What does a land line cost, anyway? But I'm reconsidering now.

    POTS lines are going away. ATT reports cutting 700,000 per month since 2009. They estimate in 2014. they will be gone. It is a shame because we cannot learn from our mistakes. Being from Oklahoma during the May 3rd tornado of 1998, cell phones were useless. Everyone and their dog was on a cell phone talking and you couldn't get a signal even trying 911. The phone just said no signal when you turned it on.

    Same thing with the Murrah bombing in 95.

    Cable TV and satellite internet were present but crude because of low bandwidth. No one had internet phone. Telephones were the only thing that worked.

    Imagine a small disaster without a public phone system.

    Imagine the Japan earthquake in L.A. without a POTS line. The internet is not reliable and old telephone lines would come in handy.


    Ham and short range CB's would rule. My handle is Snattlerake. We be 10-10 on the side...

They never minded when I'd reply, "Um, that's a negatory, Dogface. Catch ya on the flip side." Us CBers talk funny.
    LOL. When we were kids, my parents would sometimes talk to us in CB code, which amused us to no end. Then, when my dad joined the FD, we would listen to the radio and we learned the 10 code. My wife thinks it's "adorable" (her word, not mine) that I occasionally still talk to my father in 10 code, especially over the phone.

Can't you only talk to other sideband rigs? I wouldn't care for that. And another question - is anyone but truckers running CB these days? Seems like it's sort of gone out of favor.
    You can buy an SWR meter at Radio Shack that will work. Some radios, like my Cobra SSB, has an SWR meter built in that works pretty well. Using an SWR meter isn't hard to do, just follow the instructions that come with the meter. I'm using an 8 foot whip for an antenna, tuned to the center of the band (channel 20).
    You can talk to AM CB operators with a sideband unit in the AM mode. Single sideband suppresses the carrier so you use less power and less bandwidth to get your signal out. AM uses twice the bandwidth that SSB uses. Most ham radio operators use SSB exclusively on the ham bands for that reason. Some hams like to use vintage AM rigs, but there aren't that many.
    I don't even hear many truckers on the radio anymore. The bands are pretty quiet. I certainly don't miss the idiots playing music and whistling on the mic like the old days! I started in CB back when they still licensed CB operators. My old call was KAWK5821 but I never used it, preferring to use the "Hard Times" handle.

    I know a few hams who build tiny low power transceivers for under $20. They sometimes build transceivers small enough to put into an Altoids tin! With less than one watt of power, they can transmit and receive Morse code over 200 miles! You can't do that with FM voice.
    With the sunspot cycle on its way up, long range communications on the CB bands will be possible using 4 watt mobiles. I have a SSB rig ready to go when that happens. My CB handle is "Hard Times."
    Yeah, I know I should. The local club has license classes once a month or so, and it's lots easier now that you don't have to do the -.. .- -- -. . -.. code, at least for the Tech license. 2 meters, here I come! I had heard about some of those "matchbox" CW rigs. Cute!

    I am not sure where exactly it is, but there is an FCC regulation that stipulates that anyone can transmit on any radio frequency during a real (read life or death, something that 9-1-1 should have been called for) emergency. In any event, whether its breaking some federal regulation concerning radio transmission or using my firearms in self defense. I will take being judge by 12 over being carried by 6 any day.
