Preference for someone with telecomm hardware/communications background look at this...
My company hosts 20-30 web sites and we currently have SDSL service 768K Down/768K Up about 179/month. We can get ADSL service of 4M Down/768K Up for about 99/month with static IPs.
But I have heard with ADSL vs. SDSL there are inherent differences in the technical architecture and you cannot just think about the speeds that are quoted. Even if the speeds quoted were the same, SDSL would either be faster or more reliable than ADSL?
Any comments on ADSL vs. SDSL related to:
1) communication infrastructure (protocols, equipment, etc)
2) impact of other 'neighborhood users' on my speed
3) reliability
4) other
Thank you

They use the same infrastructure, with one exception, the Service level agreement, SDSL normally comes with an agreement that the line has to be working and fixed within a given period, whereby ADSL is a general service and when down, could take as long as it takes to fix.
SDSL also has a lower contention ratio, meaning you get more bandwidth during busy hours.
Persoanally I dont think is worth the cost, we use a main ISP on ADSL with 12Mbps/1.3Mbps for less than $75, then a backup line for the same cost but with a different company.

If both have the same upload speed you will see no difference by changing. Going down to ADSL may work as you are, depending on the routers you use, some routers for SDSL may need to be changed. You only need 1 fixed IP if you configure your servers correctly, this may save more money.

SDSL Synchronous (down and up the same)
ASDL Asynchronous (down is much more than up)
The pricing seems incorrect. I have not seen SDSL where the up is the same as the ADSL with the ADSL cheaper. The whole point to go SDSL is to get the faster UP speed.

The only difference that I know is that SDSL upload and download speed is the same, but ADSL they are not equal
