asked the Minister representing the Minister for Broadband, Communications and the Digital Economy, in writing, on 26 May 2011:

Further to the Minister's answer to question in writing No. 178 (House Hansard, 10 May 2011, page 54), will the amount of downstream capacity per end user on the Gigabit Passive Optical Network fibre optic link be 77.8 megabits per second if the number of end users assigned to that link reaches the maximum permitted under NBN Co.'s design rules.

The Minister for Broadband, Communications and the Digital Economy has provided the following answer to the honourable member's question:

As referred to in the answer to HQIW 178 (b), the downstream capacity of a Gigabit Passive Optical Network (GPON) link is expected to be 2.488Gbps. This capacity is available and is shared dynamically amongst the connected users active at any point in time. Addition of an end user to a link does not assign a specific "block" of capacity to that user. NBN design rules ensure there is sufficient flexibility so that all end-users can access the bandwidth ordered via their RSP. Should demand for aggregate bandwidth amongst end users connected to a GPON link prove likely to exceed link capacity, the design of the NBN allows the option to reallocate end users to another link.
