Identification of the area where NBNCo does not intend to switch off DPBO

MG made this Freedom of Information request to NBN Co Limited

This request has an unknown status. We're waiting for MG to read a recent response and update the status.

From: MG


Dear NBN Co Limited,

On 17 Feb 2020 (in an email with "Charllick Rd" in the title), NBNCo stated the following:

"Mr Wilkinson lives in one of 15 premises on Charlick Rd, Crafers West, which have been allocated Sky Muster™ (satellite) as their nbn™ access technology.

These 15 premises have the option of maintaining an ADSL service beyond the completion of the NBN-ADSL co-existence period for this area. Typically, when co-existence concludes in an area, the Downstream Power Back-Off (DPBO) is switched off.

Mr Wilkinson’s observation that this change can result in interference to ADSL services within an area is valid. However, in the case of Charlick Rd, NBN Co has investigated options and found that there will not be a need to turn-off the DPBO, and therefore does not intend to do so.

This will ensure no interference to ADSL services in the area and will not affect the nbn™ access network’s ability to deliver stable broadband service which meet our mandated speed targets to fixed line services in the area."

I am requesting the following information:

1. Identification of the "area" where NBN Co does not intend to turn-off DPBO. (Suburb name(s) are sufficient)
2. The total number of "fixed line services in the area" affected by NBN Co's intention to not turn-off DPBO.
("Total number" means any premises that is already connected or can potentially connect to a NBNCo fixed line service in "the area".)

Yours faithfully,

Mr Wilkinson
