1 Fibre Access Service Technical Overview AUSNOG-04 Tom Sykes Product Engineering, CTO Group NBN Co Limited

2 Where does NBN Co fit? FAS represents the Access Network portion of an overall service provided by an RSP to an end-user An extension of your network with tight integration

3 Product Structure One product construct with 3 network platforms Fibre Wireless RSP / ISP NBN Co Satellite

4 Service Components CONNECTIVITY ACCESS POINT of INTERCONNECT SITE CONNECTIVITY SERVING AREA EFS NTU BRAS /BNG NNI CONNECTIVITY VC ACCESS VC UNI END-USER PREMISES Network-Network Interface - 1G or 10GE - Short or Long Range optics - Protection options Connectivity VC User Network Interface Access VC - Aggregate Bandwidth - Physical hand off to end user - Logical circuit to a premises - Creates a contention ratio - 4 x 10/100/1000 Ethernet - Can be one or more - Logical link only - 2 SIP ATA Ports - Unicast or Multicast - Various VLAN tagging options

5 Access VC Bandwidth Downstream PIR (Mbps) Upstream PIR (Mbps) CIR added as required for critical/premium applications End user service performance will depend upon a number of factors including their chosen retail plan, their hardware and in-premises wiring.

6 Network Termination Unit 2 SIP Telephony Ports 4 x 10/100/1000M Ethernet Ports DRAFT: Shown for illustrative purposes only.

7 VLAN Tagging Within the NBN Co Network Based on 802.1ad Double Tags Beyond the Ethernet UNI Untagged Interface Priority Tagged Tagged (Multiple Access VCs) DSCP Mapped VLAN Remapping UNI and NNI VLAN Transparency

Deployment Example - Residential Each Access VC is

Broadband Router Ethernet POTS UNI-D UNI-V Access VC

9 Deployment Example - Residential Each Access VC is presented at the NNI as a unique S,C tag pair. Each UNI has an associated Access VC The UNI is configured as an untagged interface NTU POI RSP BNG Broadband Router Ethernet POTS UNI-D UNI-V Access VC Access VC Connectivity VC N N I S=10 Data Voice S=10, C=40 S=10, C=45

10 Telephony Capability Two SIP based ATA ports RSP Infrastructure NTU Softswitch Emergency 000 IPND Access 2W I/F Voice-UNI SIP Stack IP Address ATA Config Access VC 150k/150k BNG DHCP Server LNP Interception Configuration Server Call Termination

11 Multicast STB RG NTU Specific channels the end user is watching Access Node/OLT PoI RSP e.g.8mbps One copy of each channel saves backhaul Potentially tens of thousands of end users One copy of each channel saves backhaul e.g. 100Mbps e.g. 100Mbps Total Channel Line-up End User Network Access VC Multicast Domain RSP Backhaul Further replication can take place within the premises. Multicast VC per end per RSP user will carry active channels only. NBN Co will distribute all channels to all Access Nodes per RSP Replication Point 11

infrastructure such as PoI backhaul and NNI. An RSP can query the eligibility of a premises to receive service.

The RSP can then commence a 1-on-1 sales campaign with end user.

12 Service Qualification The SQ tool will cater for all stages of the sales and ordering process Premises Stage 1 FSA Rollout Stage 2 Individual Premises A high level indicative rollout plan will enable RSPs to prepare marketing campaigns and establish common infrastructure such as PoI backhaul and NNI. An RSP can query the eligibility of a premises to receive service. Typically the process will reveal whether the premises is physically passed. The RSP can then commence a 1-on-1 sales campaign with end user. Product Stage 3 Product Qualification Stage 4 - Upgrades Product level checks for spare UNI, sufficient PON bandwidth, presence of NNI etc will be performed. Throughout the life of the service, the RSP can perform full service qualifications to validate up-sell opportunities and manage customer expectations.
