| Re: Clue So most dwellings have two loops, each is 24AWG or thicker. This gauge can safely carry what, maybe 500mA? So with two loops on -48V at 1A we have 48W of usable DC power. If the damn ONT consumes much more, then Al Gore will have much bigger issues with it than replacing lead-acid batteries every 5 years by Joe and Jane Doe. 
We are talking DC power, already provided on these loops to power offhook phones. For the ONT, power supply filters can be put in place (capacitors) so that the ONTs do not interfere with DSL or POTS lines in the same cable. | |

Correction: most dwellings may have two loops, each maybe is 24AWG or thicker.
DC doesn't work that way. It doesn't run like AC which is why Westinghouse won and Edison lost when it came to standardization. You can't transmit DC long distances effectively unless you have high gauge wiring and enough of a step-up to reduce voltage drop. | |

| Re: Clue DC transmits better than AC. There are now several DC high-V power lines. They use DC because you don't get the reactive loss of the lines.
The problem with DC on mains power is you can not step it up or down. Edison had to run everything on one voltage because he could not step it up or down. Westinghouse (Tesla) could step up the voltage for lower losses, then step down locally.
As far as the local loop, I have worked with devices powered over 24GA wire. For a device that used about 8W, at 24 volts, the best we could do was about 700' on a single pair and 1000' on 2 pair.

| Re: Clue Thanks for the info on HVDC.
The way I took it the loss and inability to step effectively is what killed DC because placing power plants locally killed the idea for most Americans. While AC could be transmitted at high voltage and stepped down to low voltage locally.
Either way, that's why I liked BellSouth's FTTC engineering. It used 22ga cabling to power 130VDC systems. I could see an eventual move to FTTH from there could possibly allow for telco provided power to the house (which was within 1kft always). | |

| here is the math, lets assume 90v, since thats what a telephone rings at.
90 volts
0.0842 ohms per meter for 24 gauge
60000 feet, FIOS uses BPON, 12 mile limit from central office
90*(90/((60000/3)*0.0842))=4.8 watts
20000feet
90*(90/((20000/3)*0.0842))=14.4 watts
heck, I dont know how RF noise friendly this is, but if we use 2 wires, we can use earth return, and get 2 times what is there, add a 2nd pair, same thing
»fios ont power req
18watts with TV+internet+phone running (not on emergency power), emergency power will be less
so yes its feasible, you'll probably need a new ONT tho, I dont think the current ONTs are as optimized as they could be when running on emergency power, so I dont think it would be as simple as plug battery pigtail of BBU into adapter and 2 screw terminals on the other end of adapter. | |

| Re: Clue If you ever get a chance to read documents on proving in an FTTP network from a cost savings standpoint, you should browse the numbers as it makes for some interesting reading. With the rising cost of copper, it makes no sense to maintain two separate cable networks to support battery backups. In fact, that was one of the largest hurdles during the early FTTP deployments. They tried to power units from offices in the late 90's and found it to be to costly.
How many people here still have a corded phone in their home for use during power outages? Most people I know use cordless phones and are thus rendered useless in a power outage situation anyway. | |

Thus, a lot of the maintenance problems in the past can be eliminated, saving a ton of money. -Tzale You fail to acknowledge that maintaining a copper loop requires Verizon to offer the loop as an unbundled element to competitive local providers on a wholesale basis.
The maintenance savings are elimination of local competition.

Why are two crews needed? Sounds doubly expenpensive to maintain!
Yet splicing a fiber is cheaper at lesser cable bundles.
Fiber rocks, but it ain't cheaper...fiber has it's issues (moisture related as well), but I agree it is where the network provider should head. I don't think there is ANY network provider who would disagree or build otherwise... | |

| Re: Clue Training two sets of techs and outfitting them with different equipment is costly. The huge cost of copper cable materials puts it in a league all by itself when you compare it to fiber. A 100 pair copper costs 8X the cost of a 96 fiber cable in materials. With copper going up every day, this factor will only increase.
Also, Verizon is making a point of burying the fiber in more areas and avoiding aerial when possible. This puts the cable in less danger of being damaged.
If you were to rebuild an entire office from ground zero, fiber is cheaper to build. But, it is also cheaper to maintain and easier to troubleshoot problems than copper. | |

Yes it will help but they are really designed to give a few minutes (enough to properly shut down the typical PC) and are severely limited in terms of amp-hours capacity. The ONT may only use 12-20 watts but it's constant and the inverter of a UPS that converts to AC power will also run constantly. There is actually a provision for the Verizon BBU to be connected to an external 12V battery. AFAIK Verizon never implemented that with non-MDU ONTs probably because that battery would also have to be properly charged. In any case the choice of a sealed lead-acid battery shows that Verizon was primarily interested in low cost. | |

As far as I know, if there is a power failure the entire (localized) cable network goes down, not just the end users. It isnt self powered at the CO level like DSL/FIOS. All the repeaters/amplifiers on the poles require power as well, so if your area is out of power having a "wind powered" cable modem wont help.

Any hay made over this issue is hype IMHO.
People have a lot of things in their house they can't fix themselves. Heck, the last 10 years of her life my grandmother was housebound and I had to do her grocery shopping.
My sister couldn't fix the faulty valve in her toilet (I would say taking a crap might be a little more of a necessity than making a phone call, but anyway). She called me to fix it for her.
She could have called a plumber to fix it, but she decided to save a few bucks and have me do it.
I'm sure just about anyone who's ordering FiOS is going to have someone in their life that can help them with such things.
Of course, there is always and exception to every rule, but for the most part, I think this is a red herring...

I think this is a problem, but the bigger problem is if power goes out then no telephone service.
I wonder if Verizon is thinking about a solar companion for those that want a backup? Say a small solar panel that will keep only the telephone part working, for emergencies? Obviously won't work if the failure is at night, but it could be a nice option for those that want more peace of mind. | |

Which makes complete sense. Original build out of the telephone infrastructure required battery backup from the CO to power phones during time of power outages and other disaster situations. Now, monopolistic phone companies that are greedy for nothing but the bottom line redesign the system everyone is used to having where the phone company provides the power for uptime. Now the end user must be responsible for the power for their phone to work and must be semi-techinically knowledgeable to maintain it. | |

| Re: solar alternative maybe you missed that i mentioned the 'night' problem in my post, and yes, the power usually goes out when the weather is a factor. however, weather changes rapidly, so once a storm has passed, the sun comes out. those without electricity for hours, days or even weeks will also not have phone/tv/internet service. it would be nice to have a solar extended backup option that prioritizes services. so if the panel creates enough juice, phone gets service first, then tv, then internet. | |
