About 911 and Cell, I had previously looked into this; it is *technically* feasible to pre-load 911 data base with address of cell, depending on 911 software in use, but they don't like to do it (and it might over-ride the GPS-locater function that will someday be in all cell phone calls to 911), according to person I spoke to at my county's 911 Center.
Here's what I did to satisfy concerned friend about my personal safety coming home from hospital with trach (He really didn't understand it) because they made such a big deal of it before releasing me to home (and sister, who they trained to clean inner cannula, but I always did it anyway
). I ordered a power line carrier system that extends your telephone wiring on the power wiring already installed in your home, by electronically 'piggy-backing' the telephone stuf on the power wires and is intended for VOICE applications, like telephone and FAX. There are also units made for DATA, for extending satellite receivers (large market here;), and other more complicated stuf.
Here's what I ordered:
http://www.amazon.com/Easy-Jack-Wir...lectronics&qid=1236801585&sr=1-1 plus I bought a plain-jane wired telephone instrument.
I live in a small condo, with four units in each of two buildings. The plan is that I would plug the base unit into my neighbor's home and telephone jack, the extension unit into my own home and the phone into that. If I made a 911 call, it would show at the 911 center as my neighbor's address and she would direct them to me (Or we could leave a small note fastened to her door directing emergency responders to check my Unit also). There are obvious flaws, but it's better than nothing and my original intention was to satisfy my friend's worry, not actually make a call).
Consequently, I never have gotten around to hooking it up to see if it works (Other stuf on the power wires might create noise, etc.) AND I never bothered to read User Reviews -- It turns out that this company makes both Voice and Data units and their ads and ordering information don't allow a choice or even reveal which kind you are buying!! Mine are PX-211D
and they are apparently hard to return.
You essentially have to look at the unit's *complete* model number (Not in the ad or ordering info) to see a "V" or a "D" to differentiate the units. Turns out they ship the "D" unit, perhaps because that's what's best for the satellite TV receiver application; in fact, Dish recommends the unit.
One user found the Data version to be useless for his intended Voice application and that might be true for me also.
What they don't tell you is that these systems will NOT pass a power transformer, so the two locations must be on the same transformer AND anything else on that transformer is a potential noise source...
They do have this note:
QUOTE
Important Notes on Operation
� Do not plug equipment into a surge protector, plug strip, A/C extension devices or GFCI-protected outlets. Doing so can negatively affect performance.
� Equipment will not operate during a power outage. Use a hardwired phone during a power outage.
� Equipment can only be used for a single phone line.
END QUOTE
It turns out that even having a surge protector within 4-6 feet of the unit may cause malfunctions and even long-term failure.
I will post an update whenever I get around to installing and testing the system.
