Unfortunately Naked Extreme doesn't do a great deal for latency.

The only benefit is if you are extremely far from the exchange you can utilise Annex L.

What uni is that cronic

[CRoNic...]

Not a Uni Steve, it's where I work (SA Water!)

[CRoNic...]

But at home, I'm on that pair gain system, so I connect at 31.2kbps

I've argued with Telstra many, many times to get relocations, 2nd line installed and even thought about plowing a cheap bomb of a car into the local Exchange so it gets upgraded (as there's no spare spots on it to even get me off the system!) but nothing has worked.

So at home, I'm stuck on dial-up. No cable access, either. And ISDN is too expensive, and Wireless is a joke.

^^ you wouldn't happen to know a Kelly has blonde hair - in the IT department I think?

[Madaz]

Yeah im lucky we have cable otherwise it would be 28.8k for me

telstra wont do a transposition for you

[CRoNic...]

kelly Molly, PK?

Steve, Telstra simply wont touch it! I used to work for Kaz, and when I mentioned I was with them, they seemed to change their tune! But apparently it's just not possible and they've said "wait 5 years and then talk to us"

Hahahaha 5 years and I'll be out of that place! Or in 5 years, we'd all be running Fibre

SLED.. Pings - In this instance it depends on interleaving/error correction placed on he line.

Typically higher speed profiles that push the usable spectrum to the limit employ greater error correction/interleaving as a result pings increase.

An ADSL line profile essentially employs a given interleaving and target SNR.

so what you're saying is that if I log into my provider and up my speed, I'll increase the ping count but make it less stable.

I upped the speed awhile ago but kept dropping out so went back to standard.

I'm on Recommended at the moment and seems pretty stable:

What do the different Profiles Mean?

The following are the semi-technical terms for each of the Performance Profiles:

Conservative

• Can achieve speeds up to 4 Mbits/sec (~435kB/sec) but designed to sacrifice speed for rock solid connections. Used to support phone lines with poor Signal to Noise Ratios (SNR) and/or long distances from the Exchange.
  

Resilient

• Can achieve speeds up to 8 Mbits/sec (~870kB/sec) and builds on the checks used for the Conservative setting. Useful for customers who have consistent dropouts or Cyclic Redundancy Check (CRC) errors. Can provide the most stable connection out of all the performance profiles.
  

Recommended

• Can achieve speeds up to 8 Mbits/sec (~870kB/sec). Provided as the default configuration for all AdamDirect services. This ensures backwards compatibility for ADSL 1 capable modems. A robust setting that is good for the majority of customers connected to an AdamDirect Service, regardless of distance and minor variances in SNR.
  

Aggressive

• Can achieve speeds up to 12 Mbits/sec (~1306kB/sec). This setting provides for high speed connectivity. Suitable for latest generation ADSL2/2+ capable modems. This setting may be useful for short to medium length distances from the Exchange.
  

Adventurous

• Can achieve speeds up to 24 Mbits/sec (~2611kB/sec). Full speed capability is available using this profile. Your line quality should be of a high standard with a strong signal strength. We recommend attempting this setting if you have maintained a successful connection using the Aggressive profile for a period of time.
  

Thrillseeker

• Can achieve speeds up to 24 Mbits/sec (~2611kB/sec). This is an Adventurous setting with a twist: interleaving is turned off. Interleaving is a process of error control that sends data to your modem in a non contiguous fashion. This tends to provide a more error tolerant connection. Some customers would choose this profile to decrease gaming "ping" times. This profile is not recommended for general use.

oh, cod4 on sale at JBs for $59!!! woot, time to pick myself up my own copy finally =P

[Damo_R34]

is that for pc fish?

[Fishpaste~]

we are in computer jargon, there is no room for console's in here!! IMO we should destroy all consoles and make like they never existed...

so yes, its for PC =)

I'm on Recommended at the moment and seems pretty stable:

Typically running a line profile that aims to provide increased 'bandwidth' will target a lower SNR ~6db and increase interleaving that will increase ping/latency.

Depending on the ISP profiles can be configured any way they feel fit.

Typically there's 2 area's to consider. + the technology.. ADSL1 and ADSL2+

Interleaving and SNR target. SNR target determines the speed.

The Interleaving determines the stability/reliability to some extent. As you know increasing interleaving increases ping/latency.

Low SNR with no latency is the ultimate but only if you are close to the exchange, no bridge taps, internal wiring is spot on and no interference.

The Recommended profile appears to be an ADSL1 based profile.

If you experience dropouts with an ADSL2+ profile this is due to interference within the frequency range ADSL2+ uses. ADSL2/2+ uses a greater range of the available frequency to obtain the faster speeds over adsl1.

By you selecting the ADSL1 profile you are not using the frequency that suffers interference as a result your connection is stable.

Not much you can do about it apart from making sure your internal wiring is spot on and a central splitter is fitted.

I've found longer distances you can squeeze a little more out of your connection by locking it down to ADSL2 only mode (not 2+). 2+ doesn't work too well on long lines.

Hahah Fishpaste, I beat you in the Government ISP speeds

[writeoff]

Slower than when I had Internode.

probably coz of all the users leeching when they shouldnt be XD

that and you should see how much of our dl's are mysapce =(

[bezender]

a mate of mine works for a hosting company who have 4 dark fibre links that are load balenced

/dribble

basically 4 x 10Gb fibre links.... on the small portion of bandwith that he is allowed in his department he gets 78000+kb/s

he even is allowed to ave a PC in a rack there that can get 600kb/s with no d/l limit

im jealous
