EsatBT Residential ADSL

Paulw

I know they say 2.5km, but the real distance for ADSL can be up to 5km.

I certainly know that ADSL was tested to that limit and demonstrated to EsatBT before they bought the solution.

Of course, you get degradation the further over the 2.5km you are.

Yes but the gits are so inflexible about distances, I am 2.8k from the exchange (phone line wise) and they refused me, even though I said I was willing to sign something saying I accepted there might be degredation in speed

Just had a go of the 1mb dsl from esat tonight...it truly is a beautiful thing

Well, I've been using the service now for a good few days. I find it very good. Yeah you can notice the "idle" disconnects, but it's easy to reconnect again.

Speeds seem fine too.

I've been using the service since Friday, and I've been using Norton's Connection Keep Alive. So far I haven't been disconnected once.
However, I haven't left the connection active overnight, but I woud think the connection would be dropped when esat change my ip.
I've been using Esats new DSL service for multiplayer gaming and I reguarly get a ping of between 30 and 50 ms on a wide variety of of Game Spy servers.

Also, the service is advertised as 256 downstream, 128 upstream. But, I've conected everytime at 320, 160. I'm not complaining, but would be interested to know if your getting te same Paulw?

Alas I think that's a glitch with the modem, it'll report a faster connection speed than you're actually getting. Go to one of those internet speed test sites and tell us what that reports will ya?

Yeah, I'm getting the same speed reported. I did check some of those speed web sites, and they report 256. Seems fine.

As for my disconnects ... I forgot to turn off my own auto-disconnect for idle. Since I've done that, I haven't noticed a disconnect.

Are you getting many hits on your firewall?

Paulw

Yeah, getting a good few actually.

I'm using ZoneAlarm. I was thinking of getting BlackIce though.

Anyone recommend a software firewall ?????

etho_ you were right. I got an average download on a 1 meg file of 252.2
I'm getting quie a few hits on my firewall aswell. I'm using Norton System Wirks.

Its not a glitch in the modem - remember this is ppp-over-ATM.

The 320, 160 speeds you see are at the ATM layer (i.e. the adsl modem trains with the DSLAM at the ATM layer).

The "safe" estimate for the overhead of IP over ATM is approximately 20%.

Now look how that fits in.....

20%(320) = 64
320 - 64 = 256

20%(160) = 32
160 - 32 = 128

Now according to http://www.dante.net/operations/ip-eff.html, it is usually a little less, anything between 15 and 20 depending on the setup of the ATM network. So the actual IP rates are running at close to the specs of the service(256/128).

There may be a few k overhead depending on the setup of Esat's ATM network which could explain any variances you see.
