o/t...T1/2/3 internet connection

[Richgm]

Dear Webmaster, what type of ADSL is Sky marketing at the mo? They claim I'll be able to get up to 16Mbit download although I can't find any info about upload speeds.

Sky Max is 768kbps

Sky Mid and Base are 400kbps

So I 'm lead believe by people on Digital Spy

You would have had E1 had you had Home Highway installed, E1 Basic Rate ISDN

E1 Basic Rate is 2 Bearer channels @ 64K and 1 Data channel.

No you wouldn't. Home highway is 2B+D Basic rate ISDN. E1 is generally used to mean Primary rate ISDN at 30B+D.

However an E1 does not have to be ISDN (just to confuse matters) but lets not go into that here.

Just to pick up a correction on the post on differences between E1 and T1. T1 is lower bandwith because there are only 24 timeslots compared to 31 for E1

If you want a rough idea of the speed you can actually dload at....

I know those online testers can be a bit random and all that, but i can never get anything more than this...not ever.

My connection is 10 meg but often downloads will never go above 750/800ish kbs.

Is it possible my router could be to blame or does anyone else never really get the maximum speed from their connection?

I appreciate all sites etc are different and you can get very low speeds depending on many variables, but at places i know should max out my download speed, i often never do.

I'd stop complaining. You have 90% of the raw maximum, which is pretty good, at the 10Mb will be perfect new shiny copper with no contention only a few feet from the exchange.

The killer is the contention ratio, which is how many others you are sharing your pipe with. A year ago it was around 20:1, meaning at peak times in an area where everyone had a broadband connection you could be at 5% of peak rate. Generally this set of conditions is rare though and I don't know what ratios they run with these days.

Not complaining Sir, just curious is all.  

I know some people with 10 meg who can achieve over 10 meg speeds that's all.Unless that is related to upgrade testing etc or something.

Unless i am grabbing say 4 large files via a download manager, i never get that close to my maximum.

If you have an old router it might be holding you back.

As you say bill a home highway is 2B+D and not an E1 at all. and E1 is a 2048K bit stream which is channelised into 32 timeslots with the first timeslot lost to synchronisation as per G704.

The T1 underlying data rate of 56K when used with CAS doesnt make the total rate of 1.544M as the slots are still 64K. With a T1 there are 24x 64K DS1s + 8K for framing = 1544K

Where's the emoction for what the devil that went striaght over my head  

[ACW]

Oh and the info I have suggests Sky are offering the same Max and Max Pro upload speeds of 400K and 800K as they seems to be using BT Stream products to deliver this.

Also Boomy if your getting that out of a 10M it really isnt bad one you consider overheads etc. I'd be surprised if anyone gets consistent downloads over 1MByte/s from may providers and not that many folks have sufficient core bandwidth to offer mutiple downloads at those sorts of speeds. Right now it easy to get 8M ADSL download connections, but somewhat more expensive if you want say 100M of upload/download connectivity so that 20 people can download at those sorts of speeds simultaneously - which to some extent at least nullifies some advantages to bandwidths on ADSL above 4-6M.

Now whose gonna start us off discussing the various merits of AMI, B8ZS and HDB3 now we have the speed sorted ?
