CDMA / GSM migration plans -- as I am told
From what I am told by folks in the industry/infrastructure directly is the push to 3G (3rd Gen), which is GSM. North America is very lacking (got lazy) on the digital side of things. There is more fibre in the ground than needed, but none of it is in use. FINALLY, after 16 years, that appears to be about to change. About time we get VDSL, VDSL2, 3G Cellular, etc..... and catch up with the rest of the world!!!
(So much for being #1 at one time... i grew up with the now older/obsolete telco systems (dms, ess, hook, etc)). Perhaps our cell and home phones will FINALLY become ONE if we opt for that service.

ADSL vs ADSL2 vs Home vs Cell
Gang,
First, I have ADSL2+ (or VDSL2)+ (25 Mbit), clocking as 28.3 +/- (sync) here. I recently learned that when i had to get the new modem upgrade as I live less than 1KM from the DSLAM (I am on a non-spliced fibre from DSLAM -> Demux). They give us a bit extra to compensate for PPPoA (Point-To-Point Over ATM). The plan is to clock us a bit higher, but some switching equipment is not up to speed yet. When it comes, the 'upgrade' will occur automatic. The 'PROVISIONING' (service you see) is the difference.
I have to learn more about VDSL2 (Sweden) system as it is even faster.
EDIT: (FOUND IT! : http://en.wikipedia.org/wiki/VDSL2 )
The 10 Mbit rates can be clocked (sync) up @ 12.233 Mbit/sec depending on distance from the switch and the provider. Anyone with that service in the US will see about 1.2 MBytes/sec on a download from a good server like a giganews server if they have a clean 12.223 sync rate. (WHICH IS A SYNCHRONOUS performance rate.) Ignore the 'A'DSL label. You are sync PERIOD. The 'A', in my experience, simply means you do NOT have to wait for a full packet of data before it's transmitted. Your DSL modems will tell you a LOT about ALL that. Look for the attenuation/sync/other tech data about the connection ) on the internal menus/status pages (IPV4 = 10.0.0.138 for many) and modem model #. Example: a Thomson 5x6 means that a 516 is a single port and a 546 is a 4 port. Hope that helps.
Some providers provide you a 10Mbit sync rate and let you suffer the overhead and then provision you at strange speeds like 768/256. 768/80 is a common (even cable) speed around here. (10 Mbit sync will give you around 800 KB/sec.... look at the old theoretical vs practical 10Mb ethernet specs)
There will be a lot of changes when the new cables being put in for the ATSC (digitial TV OTA) change over and the US will see, effective Feb 2009 when NTSC OTA (Over the air) is discontinued. That is why the fuss about a 'converter box' US residents see. Cable Internet runs as (IIRC...) 15-25 Mhz on the wire so as not to interfere with standard signals. 10 Mbit cable runs around 12-15.
As to the question of house vs cell vs fax...... there are two types of thinking. 1) auto roll over to your cell # or 2) simply auto roll to your cell KEEPING your home number forwarded to the cell. I DO NOT KNOW yet which is the default. I am trying to learn from the guys who run the local switch here. Some know and aren't permitted to say, others simply don't know.
My Cell has been GSM since 1999 (Voicestream, now T-mobile, owned by Deutsche Telekomm)
Regarding the 'auto rollover', the classic example we all do is to be on the house wireless and get in the car, losing signal a few KM down the road. That will stop. That is the transition point to cellular-mode. In the reverse situation... a Cell call can be routed to your home wireless when you are within range or stay on the handset.
As for me personally, on home or cell #, I have auto fax detection (digital vs voice) call and keep home & cell (car & handset) separate. Digital (or data) calls get routed based on what is in the home. Since my DSL is always on, any digital call to my cellular stays with the phone and if plugged into the laptop, rings in to it. Fax is stored in the phone and provided as a 'msg' (much like picture msg) . Obviously these can be transfered via IR, Bluetooth or USB (most common) to your PC on demand. My selection has been to keep house and cell seperate and programming the CELL to forward fax calls back home to the fax line if busy.
Please do keep in mind the 3rd generation (aka '3G') phones will have more features as well as the 2100 Mhz band assigned to them. Most of us now have 3G phones, but have "2.5G" service.... we have faster data calls outbound, cleaner voice, but only have access to the existing 4 frequency bands (based on carrier). As equipment upgrades complete, more of us will simply 'switch over' from 2.5 -> 3G natively. The phone is already awaiting an OTA (Over The Air) signal from the tower to start using that 5th band. Many locations in the US have full 3G service already. It is local 'core' and tower based limitation only. Your cellular or telco ISP can tell you when the schedule is and what your options are.
As for Canada, I will learn all I can and forward it here ASAP.

PS: I do have "Fiber to the curb" (home) as it is called. There is only copper inside the home (4 wire) and from the fiber -> copper Mux/Demux unit. That unit is 20 ft from the house. The distance from the DSLAM to the CO (at the company office) is about 5 miles (8? km).
Here's a link.... and in spite of it showing ADSL2+ @ 15, we as a private LEC have more. (correction: Called the telco and I'm part of the 25Mbit pilot/pre-rollout program)

It shows the compatibility requirements and specs so you can inquire as an educated consumer and not accept some BS from a sales pitch.
