ADSL2+ Line Profiles allow you to modify your connection's technical characteristics - to balance speed and stability, or to optimise latency. Line profiles are available to the following ADSL2+ customers:
There is a trade-off between speed and stability on ADSL2+ services - the faster ADSL2+ runs, the more sensitive it becomes to interference, filtering, or connection problems. In some cases, these problems may cause connections to "drop out" (brief disconnections), or may reduce overall throughput.
Figure 1: Line Profiles and the trade-off between speed and stability
Line profiles allow you to fine tune your connection to find the best
balance between speed and stability.
IMPORTANT NOTES: In addition to standard profiles, we also have special ADSL2+ profiles to optimise latency, increase upload speed (Annex M), or for video (Fetch TV).
There are no charges to change your ADSL2+ Line Profile.
You can change your Line Profile online through My Internode:
NOTE: Profile changes typically take 15 minutes to take effect, but may take up to one hour.
If you are a new customer, have recently relocated, or your service has been
migrated to an Internode DSLAM, Internode initially places your ADSL2+ service on the ADSL2+ High Reliability profile to ensure stability.
If the ADSL2+ High Reliability profile suits your needs, then no action is required. However, if you would like to maximise your connection speed, use our ADSL2+ profile change tool to select a profile which better suits your needs (or telephone line).
NOTE: If you change your line profile and subsequently cannot connect to the Internet, don't panic - contact our Support Team on 1300 788 233.
If your home or office is a long distance from your telephone exchange, or if your connection speed is less than 8 Megabits per second, it may be worth trying an ADSL1 line profile:
In some cases, these profiles may outperform ADSL2+ profiles - improving speed or reliability (or both!). Because ADSL1 profiles always use full power (ADSL2+ profiles are designed instead to reduce cross-talk), you may squeeze better performance out of weaker or longer telephone lines.
As you push your connection to higher speeds, ADSL2+ becomes more sensitive to noise
(e.g., cabling crosstalk or electromagnetic interference). At the worst, this will cause your connection to "drop out" (disconnect), however this can also cause other problems -
particularly with throughput.
Even with a good connection speed, this noise may cause a high "error rate" - where data is not sent or received properly and has to be re-sent multiple times in order to reach its destination. This continual re-transmission of data (packets) can reduce your connection's throughput significantly - causing slow downloads.
Throughput has a greater impact on your ADSL2+ experience and download speeds than your connection (sync) speed.
If you're experiencing slowness - even if your modem reports a fantastic sync speed - it may indicate that your current line profile is unsuitable.
To resolve the problem, simply try a more reliable line profile, and then download a test file from our mirror to check your actual download speeds.
If your connection becomes unstable after a profile change, simply move back to a more stable line profile. There are also a variety of simple changes you can make to your premises to stabilise a connection or improve performance:
