Introduction

8th February 2011 Update: Trial Concluded

The trial phase of interleaving control on high speed Telstra Wholesale ports has now concluded. The trial was very successful, and interleaving control has now become a permanent feature.

• There is no change to existing service settings for trial customers who have already turned interleaving off. Your service will remain in its current state—you do not need to re-apply.

6th June 2011 Update : Interleaving Control is Restricted to ADSL2+ ('OPEN2') Ports

Telstra Wholesale has advised us that a technical issue has been identified which has impacted interleaving requests for 8 Mbps services. Hence 8 Mbps (OPEN1) services are now be excluded and interleaving requests will only be available on 20 Mbps (OPEN2) services.

So please only apply if you're on the 20 Mbps ("OPEN2") type of Telstra port.

What Is Interleaving?

Interleaving is a forward error correction technique used on higher speed ADSL services to increase the stability and throughput of the data connection.

It involves rearranging the data being transferred, in order to make successful transmission more likely in the presence of 'bursty' noise. From the user's perspective, it can mean faster downloads—but at the expense of a slightly higher latency.

Why Would I Turn It Off?

Most broadband users benefit from the interleaving trade-off, with the exception of dedicated online gamers. They tend to prefer a low latency connection, to better participate in their real-time online game, even at the expense of line stability or data throughput.

Interleaving on an Internode DSLAM Port

Internode customers connected to an Internode DSLAM port can use our web tool to select a 'Low Latency' profile, which disables interleaving. Further instructions for customers on an Internode DSLAM port.

Interleaving on a Fixed Speed Telstra Wholesale Port

Interleaving is always disabled on a Telstra Wholesale port that operates at 1500/256 kbps, 512/128 kbps, 256/64 kbps or 512/512 kbps. It simply isn't necessary at these speeds - so there's no problem to solve with these services!

Interleaving on a High Speed Telstra Wholesale Port

To date, interleaving has always been enabled on a Telstra Wholesale port that operates at high speed ADSL (i.e., the 'up to 8M/384k' OPEN1 ports); or ADSL2+ (i.e., the 'up to 20/1M' OPEN2 ports). These ports are used to deliver Internode ADSL services, such as Easy Reach and the earlier ADSL Fast plans.

We now have the ability to disable interleaving on an Internode high speed ADSL service delivered via a Telstra Wholesale OPEN2 port, a process also known as 'Fast Path'.

Frequently Asked Questions

How Much Does It Cost?

Currently there is no charge for this feature.

How Long Does It Take?

There's still a degree of manual processing required, our objective is to process each request - either to turn interleaving off, or to turn it back on again - within one business day. It can take another day or two for our wholesaler to complete the request.

What If I Want To Change Back?

No problem—if disabling interleaving makes your service unstable, simply use the same web form to request that interleaving is re-enabled.

Of course if your service becomes severely unstable, just call Internode support on 13 66 33 with your request.

Important Conditions

It is important for you to appreciate that the removal of interleaving from a noisy line can cause your ADSL to become unstable. In particular, if you are disabling interleaving on a Business ADSL or Business Pack service, our normal SLA rebate will not apply.
