Actual ADSL line speeds

[dagr]

I have just changed Internet Service Provider (ISP) at my house here in France in favour of a non-France Telecom company. All ISPs here are offering ADSL2+ lines but I never seem to get near the theoretical maximum (24Mbit/s). When I speak to Technical Support they annoyingly say I should be getting near 20M since I live near their DSLAM and don't understand why I'm stuck at 10 or 11M maximum, often less, with barely 1M upload.

Is this just a France thing or does the UK have similar gaps between reality and what's advertised?

(I'm still glad I quit France Telecom, but I'm wondering if it's worth upgrading the 512Kbit/s line at the UK office).

David,

If you give me you phone number of the ADSL you have at the office (pm me if you prefer) I can do anavailability check for you. This should give a pretty good indication of what you can get on your line.

I use Bulldog and the service is not so fast! I am supposed to be getting 16MB but it is still slow!

Due to the way that the ADSL technology works, you will never actually achieve the full rate of 8Mbps or 24Mbps. This is due to error-control communication that is part of any DSL connection.
The actual maximum throughput limits are:

7.2Mbps on an 8Mbps ADSL service
21Mbps on a 24Mbps ADSL2+ service

Also, nearly all ADSL broadband services available today are contended. A typical home service is 50:1 and a business sergvice is 20:1. There are only a few ISPs that actually offer 1:1 DSL services but they are relatively expensive, but you do not share the bandwidth.

Hope that helps...

cheers,
Tema.

Thanks folks.

Rupert, I did check it and it can apparently support 8M (in theory).
