This second location, which we call an "Aggregation Node",
then becomes the PoI for access seekers. In this case the Fibre Access
Nodes are not PoIs.
There are, of course, a few more variations on this theme, but I
think you will have got the concept.
There are likely to be between 100 and 200 of these NBN Co
PoIs throughout Australia and their location needs very careful
Where we place these PoIs may have an impact on industry
structure so we will be consulting with the industry and holding
discussions with the Government and the ACCC to ensure we get
this placement correct.
By limiting our scope both in the geographic sense, from premise
to PoI, and in the network sense, by not going above the Ethernet
layer, we are occupying as small a footprint in the overall value chain
This leaves plenty of scope for the users of our network, the access
seekers to build facilities, innovate and develop new services.
It is now time I mentioned the support systems.
Business Support Systems (BSS) support processes such as sales
activities, customer interactions, taking orders and processing bills.
Operational Support Systems (OSS) support network processes
such as maintaining network inventory, provisioning services,
NBN Co plans to build a low-touch, self-serve, business and
operational support environment.
Because we are a startup and building a new network we have
no legacy systems constraining our design.
We are also doing everything we can to keep both the wholesale
product suite and network as simple as possible.
This reduces the complexity of designing and building the OSS
and BSS, which as we all know is one of the complex challenges all
Given this, we have set ourselves some requirements as we
design our BSS/OSS. These are:
h high transaction
mes with variable
transparent processes and automate
ordering, provisioning, assurance and billing.
f access for service providers regardless
of size and capabilities.
king to Access Seekers so they can
add, delete or modify services as simply as possible.
We will, of course, be discussing these and other requirements,
and their implementation, with potential access seekers.
Turning now to the solutions for the 10 per cent of premises not
For this remaining 10 per cent we are aiming to provide a
wholesale product using both wireless and satellite technologies.
We would like the wireless and satellite products to be as similar
Nevertheless, we will do our best to align the products as much as
The question of spectrum availability for the parts of the country
where we will need to use wireless is still an issue to be resolved.
There is obviously an advantage in using spectrum at the lower
end of the range so that we can use larger cell sizes and reduce the
number of cell sites needed in low-density areas.
This will keep costs to a minimum.
Given the size and demographics of Australia, we will need to
use satellites to reach the last several per cent of the population.
This is the only economic way of doing it.
We believe this will likely be done with a couple of new Ka band
satellites. Current satellite designs are available that can provide
capacities of close to 100Gbps.
wireless and satellite solutions and the outcome of these calculations
will inform our choices of where the technology boundaries will lie.
The capabilities of each technology and the dimensioning
choices we make will of course be included in our wholesale product
We are intending to have an extensive industry consultation on
this wholesale product suite, prior to the submission of an access
undertaking to the ACCC.
So, in summary, we are in the process of developing a wholesale
product suite that will:
-- Support differentiation and innovation by service providers --
by providing them with an experience as close as possible to
owning their own network
-- Offer open access and equivalence to create a level competitive
-- Promote ma
-user choice in terms of both services
-- Deliver appropriate network reliability, resilience and security
-- Allow secure simultaneous delivery of multiple applications
with predictable levels of quality
-- Offer flexibility in terms of speed, usage, degree of symmetry
and quality of service.
-- Support legacy services, with for example, an Analogue
Telephone Adaptor on the ONT.
We will also plan for the evolution of the network as speeds and
capacity demands increase.
life, the active equipment will need to be upgraded as technology
So we are giving careful thought to the potential upgrade paths
from the 2.5Gbps GPON systems of today to the 10Gbps systems
which will be available in a few years and then the 40Gbps systems
which may be available with Wavelength Division Multiplexing
Passive Optical Networks (WDM PON).
I will now say a few words about getting the network built.
