Time Warner Cable - Legacy → Re: [Internet] backup modem with Time Warner

Addicted to the internet much? I work from home and if my internet goes out I'll just go into the office...

If you are home-bound, and rely upon medical telemetry you are not going to any office. But your point is well taken. Maybe you can live with an outage if you have acceptable recourse.

The medical telemetry I've been around all uses the cellular networks for communication back to the home office.

Good for you!

And good luck next super-storm.

You might want to consider that the op has asked about a sensible, cost-effective, and fault-tolerant solution.

Exactly, so why did you bring up medical telemetry? OP just wanted to know about a backup modem. Not fault tolerance....

And I'm betting that during super storm Sandy fault tolerance wouldn't have meant shit if you lived up in that area...

In my particular area, we lost power for over a week, but my phone service never went down.

Never give up your pots line!

In the past medical telemetry equipment just hooked up to a phone line and dials out every so often and/or dials out in an emergency. (e.g Home Dialysis) More recently I have seen stuff with built in cellular devices for communication so you can actually go be outside and still wear your monitor.

In any case, Internet access is a necessity for modern life, certainly for those like me who do not subscribe to television anymore and get virtually all entertainment on-screen by means of internet. But it isn't a "life or death" situation. As others have mentioned, if I really really needed internet, i'll set my phone as a wifi access point, and just limit traffic to web browsing and email. It seems that people have forgotten what life was like before we had internet. And an outage isn't really an outage anymore these days with everyone having smart phones that connect to the internet.

Where my apartment and office was in Manhattan (several miles apart), we lost power, POTS, cable, DSL, fiber, cellular, you name it, for quite some time. In fact, in various parts of the the city, they never fixed the ancient POTS and simply told customers they could switch to fiber or another solution for voice.

How could you have lost your POTS connection? We are talking straight copper from your premises to your serving telco central office (which in my case is the 18th St. co).

Do you really have a pots line terminated with a dumb phone which requires no external power?

During our last major storm of ice in 2002, I was without utility power for a week. 36 hours in to the power outage and my POTS line went dead. It didn't come back for nearly 3 days after power was restored in my area.

IIRC there was a lot of under ground flooding that damaged a lot of equipment when Sandy came through.

In my location, which is virtually served because we are too far from the CO, our phones will be out within a day if the power doesn't come back up in the area. DSL will be down right away. Verizon has to bring a generator out to the remote terminal to keep it powered up. In some cases, they don't end up doing that at all.

Our cell towers also behave similarly. They will fall to EDGE or 1X service after about 6 hours without power.

Salt water does not mix well with any sort of wires/equipment. Sandy was a real bitch.

In the event of a sustained power outage, only your pots lines will remain operational. In my high rise, all my FIOS/TWC voip subs lost their land line phone service within minutes after the East 14th Street substation explosion. Everyone with copper continued to have service.

Two of our Manhattan CO's took a hit-

140 West St. Central Office 1-day outage (hardened after 9/11)
104 Broad St. Central Office 11-day outage (should be hardened by now)

Yeah SO long as the POTS lines are not damaged, which happened to ALOT of people during Sandy and VZ said FU get wireless or whatever... We aren't fixin it.

Edit: And that left DSL subs screwed since they used the same POTS lines...

I know people who didn't have a POTS phone line for 3 months after Katrina hit. And no, they didn't live near New Orleans or the coast in general, but about 2 hours inland. The damage from Katrina was so widespread the telephone companies just didn't have enough time to fix it all.

As a matter of fact, the mobile masts were up and running a lot sooner, as 1 mast covered e.g. a 5 mile radius, and it was easier to just put a generator near it and get communications back up in an area.

The same people by the way did not have electricity for 4 weeks. That was a higher priority to get back up and running then phone lines I would think.
