With the rollout of the NBN progressing, there have been plenty of people complaining about poor performance after being switched. Given many people were previously connected to ADSL that's a surprise. My experience of ADSL is that performance is highly variable. But with the ACCC interested in speeds and how they are measured, NBNCo is taking a proactive step by looking at the quality of the copper in people's homes.
Back in April, we reported on how the ACCC might go about validating the promises made by RSPs when it comes to network performance.
Networks are only as fast and reliable as the weakest link so it makes sense for NBNCo to take a proactive step in diagnosing issues that can hamper performance.
While issues like CVC are significant, local issues can also be a factor. And one of those might be the quality of the copper at your premises.
Documents made public recently [PDF link] reveal that NBNCo will begin testing the quality of copper leading into some premises in order to ascertain whether performance issues rest with the core network or the copper.
Of course, ditching the copper entirely might be a good idea but that ship has sailed.
