Telstra's ADSL may soon be within the reach of 1000 customers currently cut off from the broadband service.
The Telco is conducting a national three month field trial, hoping to extend delivery of ADSL residential broadband beyond the current limit of four kilometres from Telstra exchanges.
This could attract 1000 Telstra customers who have registered an interest in ADSL but live beyond the reach of the current service.
The trial will measure the amount of noise interference when copper is deployed over longer distances.
Telstra General Manager, Access Technology, Jim More, said that during the trial, participants would see their transmission limits scaled from 56dB to 80dB until the end of January when the trial ends.
"With broadband via ADSL now available to around 80 per cent of Australian household and business lines we continue to look for ways to extend the ADSL broadband footprint in Australia through technical innovations and solutions that are helping us get more out of our existing technology," said More.
"Having said that, these are very early days and the results of the trial will be critical to any future decision."
Spokesperson for Telstra, Pat O'Beirne, was unable to put a figure on how much the trial would cost and on how likely an extension of the ADSL range would be after the trial.
"We will not be able to make any comments like this until the completion of the trial at the end of January," he said.
Telstra has over 10,000 exchanges throughout the country. It recently announced it had over one million broadband customers, 530,000 of which were BigPond customers, the rest wholesale.
Optus has 250,000 broadband subscribers.
