The carrier I work for (TDMA/GSM technology) uses triangulation to determine your approximate location. The 911 operators have the address and the GPS coordiates of the nearest tower and can tell the sector your are calling from.
There may be one or two carriers that use GPS enabled handsets, I'm not sure. Anybody know?
Cingular should allow you to dial 7 digits to numbers in your area code in LA... the dial plans for the area allow it. AT&T Wireless follows the dial plans as specified at the NANPA http://nanpa.com/area_codes/index.html... do a search for your area code to see the allowed dial patterns.
A lot of other areas are moving to a forced 10 digit pattern because they are doing area code overlays of a physical area. LA has been doing splits of areas when introducing a new NPA. The 7 digit dialing is almost always retained when this happens.
I'm an employee on the AT&T side of this merger and this is something that will have to be fixed relatively soon. Our customers scream bloody murder if their 7 digit dialing breaks for any reason... so I doubt that it's going away. My hopes are that it'll come to a Cingular network near you.
I'll get back to you on whether I welcome my new Cingular overloards...
Kits are available on eBay to do this to most any phone. I unlocked/unbranded my Ericsson T616 and T68i this way... all for a grand total of $15. The best part is that I was able to update the firmware in each phone to it's latest revision. This drastically improved the signal reception of my T616.
I agree. Since the tech industry is dying, I've been thinking about going back to law school. There seems to be plenty of work for those that specialize in IP, patent, or copyright law.
I put my nokia 5160 in test mode and did some tests. 4 bars is about -51dB to -66dB, 3 bars is about -67dB to -83dB, 2 bars is about -84dB to -97dB, 1 bar is about -98dB to -113dB. Each bar seems to be about 15-16 dB. In my experience, call quality is nearing the awful range at about -100dB.
The reason that AT&T was so attractive to Cingular is they use the exact same technologies: TMDA and GSM. It's so much easier to pool the entire subscriber base that way.
TDMA is not being retired any time soon. AT&T's GSM network is no where near large enough to handle the entire subscriber base. Once the Cingular overlords take over, this may change.
This is a retirement of phones that only work on one frequency band and suffer dropped/blocked calls due to not being able to use AT&T's entire available spectrum in those areas.
A tech came to the house. Installation is a cable modem swap that has 1 ethernet connector and 2 RJ-11 connectors on the back (only #1 can be used unless you get another line). Plug the RJ-11 into any phone jack in the house and your set. The tech has to register/activate the phone via a web browser. The whoe thing took 10 minutes.
Initial reaction to limited use is the quality of the voice is good with no noticable delay. I haven't noticed any speed difference in my data connection while on the phone, but I haven't tested that extensively yet.
Thier handout that comes with the modem says basic 911 is included and E-911 is available in some/most areas. It's most likely tied to your billing address.
With a chatty teenager and wife in my house, it's saving me a bundle... about 50% over Verizon or AT&T Local.
My daughter loves to play games from the Jump Start series. I have seen her learn quite a bit about logic and language from these. She has also become quite proficient at operating my aging PowerMac 7200.
I don't let her play to the extent I used to play my Atari 2600 ('til I had blisters on my thumbs). I use it as another tool to teach and amuse along with more traditional methods.
Don't limit your options because something isn't tangable. It is equally difficult to 'grab' something in a book.
The Caller-ID with Name feature works on that database dip...not the Caller-ID itself. The return result from the dip is the name, etc. If they'd just link their databases, the Caller-ID with name would work over expanded areas and would not add any measurable amount to the call delivery time.
The SS7 messaging carries the calling number from originating phone to terminating phone. Every switch and trunk in every carrier along the way must support SS7 for this to work. If there is a change in the signalling type on a trunk/switch, the calling number is invalidated as 'caller-id' and not displayed as such. It is still passed on to the next switch and used in the billing records.
PBX switches originating calls will sometimes send a trunk number as caller id for all calls. It may or may not show up as caller id, but it will show up in the billing records.
I started writing to my congressmen...but I started to think 'What if this goes through. Will I then be labeled a terrorist and deported for my opposition to this bill?'
Maybe I'm getting too paranoid...gotta stop reading/.
I work as a network engineer and I do the routing for one of the major cell phone companies here in the U.S.
To answer your question, until 11/24/2002 phone numbers, for the most part, are given out in 10K blocks (NPA/Nxx) to specific compaines; wireline, wireless, whatever. In theory, if you know the first six digits of the phone number, you can tell if it's wireless or wireline. That is, if you have access to that information (like I do). To the best of my knowledge, I don't think people outside of Telcos have access to this so the point is moot.
After 11/24, all Telcos will be participating in number pooling. Basically we donate numbers back to the pool for other carriers to use (if we're only using 50 numbers out of 10K) and whatever we still use is routed back to us via local number portability. So now even if you had the aforementioned information, it could be invalid. Basically your screwed one way or the other.
To further complicate matters, after 11/24/2003 all numbers will be portable between any carrier within a rate center. So you can move your number from (ex.) Verizon landline to AT&T Wireless to Nextel, to AT&T Local Services...and on and on....as many times as you'd like. By then, it's impossible to know.

If you really need to hear a talking clock, call 202-762-1401. The service is provided by the US Naval Observatory.

Compare Mac OS X Server and Apple Remote Desktop to what you work with now. You can do a lot with these packages.

If they sneeze into their hands, say 'nice catch'.
That loophole is probably filled by these phrases:

"...for the purposes of direct or indirect commercial advantage
and
"... by rental, lease, or lending, or by any other act or practice in the nature of rental, lease, or lending."
Of course, IANAL.

That's a TDMA phone and is not affected by this 'upgrade'.
I just got that installed yesterday.

...about $50K worth of overtime implementing LNP translations in my companie's network. It worked out great for me.
If only I could port out my work number so I could get some better service...*sigh*.

They could use bluetooth for that. You could hop from game to game as you discovered new networks or devices.
The ties just keep the foreskin from rolling up over thier heads.
