I upgraded to DSL a few weeks ago; previously I used a 56k modem 
connection to the Internet.

The refeence to 'frame' as in 'Frame Relay' and 'ATM' as in 'Asynchronous 
Transfer Mode' describe a set of communications protocols and equipment 
that effectively do the same job. 

The VHS and Betamax analogy is perhaps a little misleading because we all 
know what happened to Betamax which curiously produced the better 
picture. Frame Relay and ATM technology is in widespread use throughout 
the World and neither is going to disappear overnight like Betamax.

If you look at the Verizon tables (Bronze, Enhanced Bronze, Frame, ATM) 
you will see little difference in performance between the different 
technologies and tariffs. The download speed is 768kb/s and upload speed 
is 128kb/s whether you choose Frame or ATM (Bronze). Speak to friends and 
see what they use and recommend. Your choice will likely have an affect 
on the type of equipment (modem / router) you will have install in your 
home.

(I installed a 4-port router at home because it will enable me to connect 
up to 4 computers to the Internet and use them at the same time.) 

However, beware 'small print'. Look at the description below the lower 
Verizon table. Connection speeds are greatly influenced by the quality of 
your telephone line and the distance between your home and telephone 
exchange. Your line should be professionally tested and your ISP will 
arrange this. If your line quality is poor or you live some distance from 
your exchange you may be disappointed with the results of DSL, assuming 
it will work at all.

I am very fortunate because I live near my telephone exchange and I have 
the fastest connection possible. It's an ATM (or PPPoA) connection. My 
downloads speed is at least 10 times greater than my analogue connection 
which is a blessing. I subscribe to dozens of online clubs but the Rollei 
camera club generates by far the greatest number of emails and a fast 
download is vital. In about a minute I can download around 200 - 250 
emails using DSL. Using a 56k modem I would be lucky to download 30 
emails a minute. That's the kind of performance improvement you can get. 
I use Emailer 2.0v3 and an old Quadra 650 computer (33Mhz) with a 
domestic DSL connection (Pipex Xtreme Solo) to the Internet. My office PC 
is a 700Mhz Toshiba laptop connected to the Internet via a high-speed 
proxy server. The email client is Outlook 2000, a corporate choice. Which 
system do you think is faster at handling emails? The Quadra and Emailer, 
of course.

I have retained my 56k analogue modem, just in case.

Regards

Phil.
