What bandwidth to you get with your single user DSL connection?
My mom has SBC DSL in California, and it’s about 384 kbps. DSL speed varies widely depending on who you get it from, how far your house is from the phone office, etc.
I am getting 723kbps down and 104 up at the moment. I’ve seen it as high as 826kbps. YMMV depending on:
- Your distance from the central office,
- The quality of the copper run from the office to your home,
- The type of equipment and current network load.
I’m getting 1279kbps down right now, I’ve seen it as high as 1400.
I should clarify this. By equipment I meant the fast packet switching equipment and IOF (interoffice facilities) that the DSL provider has purchased from the telco. My provider buys ATM trunks with UBR class of service from the local telco and uses them to supply DSL to residential customers.
UBR is unspecified bit rate, meaning DSL will be the first to lose bandwidth if network resources become tight, as the network favors CBR (committed bit rate) and NRT-VBR (non-real time variable bit rate) customers who are paying big bux for guaranteed network availability.
My provider offers a higher class of service which promises something closer to full T1 download speed (1536kbps). I’m sure it costs probably double what I’m paying now, and I don’t need the extra 700k for $60 a month. I hardly use what I have now.
720 down, 126 up.
The download rate is typical for my connection; not sure about the upload rate, as i can’t remember what it usually is. Seems about right, though.
512/128. AFAIK, the highest available in the UK is double that. And IIRC, the highest possible with DSL technology is 8Mb.
721 kps throughput
1500/384 guarantee, following recent upgrade offer from 384/128. I actually measure out consistently at 4.<something> mb download, and have a strong temptation to give the screen a raspberry every time I see one of those Comcast ads about how much faster they are than DSL. Of course, I’m 6000 feet from the CO, and must have clean copper - when I first got DSL, the installer told be he tested the line as good at 6 mb. OTOH, the dslreports speed tests also tell me that other people on my ISP in this general area are also getting download speeds in the 4 mb range.
Apart from the guarantee you are given, your service may involve a speed cap placed on it. My old 384 service was capped at 1500. I found this out when I initially had a problem with my upgrade, and my ISP found that SBC hadn’t removed the 1500 cap. I’m now supposedly capped at 6 mb.
We’ve got a pretty good ADSL hookup at work. It’s not “single user,” but I don’t believe there’s anything special or expensive about it; in fact, we switched providers recently because we were offered this service at a better price than our old service. As far as I know, this service is available to residences in the area. My office just happens to be very close to the local telephone substation, and as others have said, that makes all the difference:
According to www.testmy.net:
Your connection is: 2015 Kbps (about 2 Mbps)
You downloaded at: 246 KB/sec
Your TRuSPEED™: 2257 Kbps :: 276 KB/sec (12% overhead factored)
Bottom Line: You are running: 36 times faster than 56K and can download 1 megabyte in 4.16 second(s)
According to www.bandwidthplace.com:
Speed 2.5 megabits per second
Communications 2.5 megabits per second
Storage 302.5 kilobytes per second
1MB file download 3.4 seconds

I have Verizon DSL out of Brooklyn. IIRC we’re only 3,000 feet or something from the co. I usually get around 1300 or 1400, and I’ve gone as high as 1532. Good enough for a zero ping on some NY based 3wave servers.
Rated for 6000 down and 768 up. Test out to as high as 5100, depending on other traffic on the web, time of day, sunspots, etc. I’m quite happy with this as it’s functionally impossible to get higher than about 5200, thanks to the “overhead” losses inherent to ADSL technology - packet frames, QoS info, etc.
There’s about 5500 feet of wire between me and the CO, and I have an actual DSL splitter installed at the MPOE, rather than microfilter dongles at each jack.
