Re: Unlimited
DSL's limit is close to being reached with SBC's 768 up Since most DS-1s these days are delivered over HDSL, I would have to say that you are mistaken. |

Sure, you may get symmetrical 1.5Mbit/s out of HDSL and 4Mbit/s out of SHDSL, but you're killing the voice spectrum on the DSL pair, killing the voice spectrum on any pairs next to the DSL pair, and getting 'only' 1.5-4Mbit/s down when ADSL2 is getting 24.

768kbps is the max DSL will run at for upload. Zak3056 is the one who is mistaken. The DS, OC, or T1 lines feeding your CO may provide higher uploads, but the DSL technology can't feed that bandwidth between the CO/RT and your house. The theoretical limit is 1.0M but nobody is ever going to see that sort of upload on DSL and maintain reliability.

That's ADSL2+ and it's in daily use outside of US, f.e. in Europe.

ADSL2+ is also being widely deployed in Canada, albeit without the higher upload speed option (3Mbit/s) because to get the higher upload speed, you have to kill the voice spectrum. No telco wants to kill the voice spectrum, especially when it can cause issues with neighbouring pairs on the same drop. As it stands now, the maximum Bell offers is 16/1.

I wouldn't have said so before a few months ago, but I'm quite tired of my ISP right now.
