• POTS replacement [telecom]

    From David@21:1/5 to All on Sun Oct 10 12:54:53 2021
    There exists a species known as "POTS Replacement" router.

    It refers to, in effect, a cellphone that you screw to the wall; it has
    an RJ11 jack for a POTS phone. It's used where you can no longer order a
    POTS line from the LEC, such as in much of Verizon FIOS territory.

    VZ tried to foist off an older version called Voice Link on some coastal
    NJ/NY areas where their cable plant was destroyed by Sandy; it backfired
    badly for residence use.

    But current products do well serving existing dialup alarm systems, and
    NFPA fire alarm systems. Another term is "Elevator Phone" as elevators
    require emergency phones.

    I wonder what, if any, models CDT readers have experience with?
    I seek one with:

    a) 1 Line, RJ-11 jack
    b) The carrier will be AT&T Wireless
    c) LTE Voice {and maybe even 5GeeWhiz...}
    d) It needs jacks for external outdoor antennas
    e) And 12/24VDC power


    It's not for a fire alarm, which requires NFPA approval, just voice.

    There are VoIP adapters which are able to connect POTS instruments to
    a VoIP access. They're almost certain to cost less than a cellular adapter.

    Of course, I'm asuming that you have Internet service and would keep
    it no matter what the cost of each option.

    No broadband there. Hence the cellular request.

    Every time I read about cellular devices repacing copper pairs, I
    remember the job my brother had in South America: he was building
    solar-powered cell sites for a subsidiary of GE.

    He told me that every site was located on a mountaintop, accessible
    only by helicopter.

    Your memory is a little off on that. Many of the sights were on
    mountaintops were the only rapid way to access them is helicopter. Many
    of those had very rough, hard traveling for days at a time, road access
    but about a 1/3 did not. We also had to install them at every telephone exchange in the southern part of the country because the system needed
    access to the individual local telephone exchanges to put the calls onto
    their POTS network. The existing connections between rural exchanges was microwave and they said that they only had trouble with that very
    rarely. I asked the Telefónica Argentina project manager why they were insisting on steel equipment shelters for installations on ridges and mountaintops, that were being built using helicopters which were real
    beasts [S-64 Aircrane class birds], when they were allowing us to use
    walk in refrigerator kits to make the shelters at the exchanges. He
    chuckled and said, through pantomime, that the bored gauchos on the
    pampas below were likely to shoot at the shelters with their 30/30 lever
    action saddle carbines. The steel skinned shelters would stop the 30/30
    bullets where aluminum shelters or the metal skinned Styrofoam panels of
    the walk in refrigerator kits, which we had used so successfully in so
    many other places, would not.

    A side note on that project was that I carried an extra suitcase
    everywhere that the crew went and I filled 2 20-Liter size water
    carriers with fresh water at the start of each days driving between
    the work sites. The suitcase was one of the monstrous roll along hard
    shelled type that is almost always charged as overweight when flying.
    Finally the crews curiosity got the better of them and they asked what
    was in the suitcase after noticing that it's weight never changed and
    they had never seen me open it. I just opened it for them because my
    Spanish is so bad that the only phrase I knew was "Where is the
    bathroom." They gawked at my large supply of freeze dried food,
    international multi fuel stove, pots, & eating equipment for 8
    people. They asked me what it was for and I pantomimed driving the
    truck, the engine sputtering, and our coming to an unwanted stop. I
    looked all around and shrugged my shoulders, talked on the satellite
    phone without actually using it, indicated 2 days to them and began
    the set up to cook. They asked "So Much?" I gestured 16 days for me or
    2 days for all of us. I then repeated 2 days for all of us and showed
    yes by the customary shake of the head recognized everywhere I've been
    in the world. After that they went obviously out of their way to do
    anything which I indicated needed to be done. I had obviously risen
    very much higher in their esteem. I put a large duct tape stripe
    across the suitcase and wrote out word by word, from my English <>
    Spanish dictionary, My life long crew leading mantra. "Take care of
    the people and they will take care of the work!" After that they
    showed that suitcase to every one of the managers and overhead types
    who came to the work sights like a show and tell. Many of them saw how appreciative their construction people were of my looking out for them
    and got the idea. I cannot believe that so many people in management
    are total strangers to that concept.

    It sometimes took days to drive from one town to the next and we stayed
    at rural guest houses at ranches along the way. When Teleffónica
    Argentina realized how much Westinghouse (not GE) was charging them for
    my time they had another crew that would leap frog to every other
    install and had me driven to an airport to fly to the next install. I
    left the suitcase with the crew I started with and told them to just
    leave it at the Buenos Aires office when they got back. A week later the
    other crew had a much older but fully functional satellite phone, a
    couple of crates of food, bottled water and a little gas stove on which
    to cook. That crew looked at their boss like a Martian had landed. He
    pointed at me and indicated that I was crazy and they only did it to
    humor me. When he was gone each one of them shook my hand like I was a
    long lost son. It really isn't rocket science. I taped the same mantra
    onto those containers as well. "Take care of the people and they will
    take care of the work!" We got a lot more shelters built and fitted out
    in one month than anyone at Westinghouse thought we could. Gee I wonder
    why?
