John Linton For those readers of this blog who did not attend yesterday's NBN Co briefing (which included me) these are the observations of someone who did:
1,000 Fibre access nodes will be deployed each
serving 80,000 premises maximum = 93% fibre coverage
· Fixed wireless technology for next 4% will be based on
LTE but with no ‘mobile’ network capabilities – though I suspect this could be
done in software by an aspiring/innovative company… Due for deployment in
Early 2012 (!)
· Satellite services for the last 3% will be based on 2
x Ka band high power 80Gbps satellites that NBNCo will build and operate
offering the same 12Mbps down and 1 Mbps up Basic service plus telephony
· I assume the same NTU will be used for
Fibre/Wireless/Satellite services – 4 x UNI-D (10/100/1000 Ethernet ports) and
2 x UNI-V (RJ-11 POTS ports delivered via integrated ATA and SIP client)
· Future Gpon technologies include “4NGpon” which can
deliver 100 Gbps over the same passive infrastructure
· Network is Layer 2 only BUT they are using IGMP for
Multicast delivery
· Developing full B2B now with various discussion papers
and specifications available on their website
· They have about 1,800 FTE staff now
· We need to get a copy of the “Wholesale Broadband
Agreement” – due for release in mid 2011 and any variation made for one WSP/RSP
flows to all WSP/RSP, all agreements will be public!
· POI capacity is shared amongst all WSP/RSP – the more
capacity that is used the lower the cost gets over time – NBNCo has a fixed 7%
IRR effectively passing on scale economies directly with lower cost
· 120 POI’s – 80 Metro and 40 Regional
· Aerial fibre will represent 18% of deployment
· NBNCo is now responsible for Greenfield/New Estates as
of 1st January 2011 (which seemed like a surprise to them) – this is
all new estates with > 100 dwellings. They have 368 DA’s pending for
these and Telstra will hand over their development sites ~ 1,000 sites
· All services will have a consistent POI, Interface,
process, systems etc
· NO VOLUME DISCOUNTS FOR ANY CUSTOMER….
· Each UNI-D (4) and UNI-V (2) on the ONT can be
supplied by a different RSP – so in the extreme, the household could get 6
invoices…
· The Connectivity Virtual Circuit is where the
contention is specified – either nationally or per POI and per Class of Service
· Class of Service
o 1 = Real Time =
Telephony
o 2 = Interactive =
Interactive Video and IPTV
o 3 = Transactional =
Business Data/VPN and Gaming
o 4 = Best Effort = Web
Browsing
· Recommended reading
o http://www.nbnco.com.au/wps/wcm/connect/main/site-base/main-areas/publications-and-announcements/publications/
· Product roadmap has 5 releases every 6 months
o 1 – Broadband and
Voice
o 2 – IPTV
o 3 – Business
o 4 – Enterprise
o 5 – Enhancements
· CVC backhaul circuit is $20/Mbps
· Sydney POI is in Global Switch
· Migration of services has been studied in detail –
there are approximately 20 scenarios
So you can see how one 'industry participant' saw the various presentations.
