5 1 Introduction NBN Co Fibre Access Service (NFAS) is a wholesale, layer 2 based Ethernet Access product utilising Fibre to the Premises (FTTP) technology. NFAS provides Access Seekers with an Ethernet access solution from the NBN Co Point of Interconnect (POI) to the End-user interfaces on the Network Terminating Unit (NTU) located at the end-user premises. This document provides Access Seekers an overview of NFAS products, the key features, product components and their attributes, major network connection elements including Access Seeker interconnection arrangements and product pricing structures. Consultation The release of NBN Co s product description represents the culmination of an extensive industry engagement program on NBN Co s fibre product. As a wholesale only provider, NBN Co has been keen to engage with industry to understand the industry s product requirements. NBN Co has been actively engaging with access seekers (Access Seekers) since its inception. NBN Co has engaged with Access Seekers through a mixture of industry wide processes and bilateral meetings. NBN Co has also engaged on technical matters with industry via the Communications Alliance and met and presented to other industry groups. On the industry wide front, over 1000 attendees have participated in NBN Co s industry consultation forums: Three Product forums were held in Sydney, Melbourne and Perth (Perth jointly with Communications Alliance). 10 Network and Operations forums were held in Sydney (4 sessions), Melbourne (3 sessions), Adelaide, Perth and Brisbane. NBN Co presented to Communications Alliance members at two forums in Sydney and Melbourne on its product technical thinking. NBN Co released a public Product Consultation paper in December Nearly 50 submissions were received from industry and interested stakeholders and we released a response paper in March On the bilateral front, NBN Co has held a number of deep dive product and operations workshops with a number of key retail and wholesale service providers. NBN Co has completed approximately 150 hours of direct product deep dives in workshop sessions with over 25 access seekers spread across Australia. These sessions are designed to ensure that we get as much information as possible from our prospective customers to ensure that we develop the right products, operational systems and processes for industry and End-users. We have received a significant amount of valuable feedback from these engagements, much of which has been incorporated into this product paper. However, if you do have any further feedback Page 3

6 on this paper, please respond by 2 nd September 2010 via to: feedback@nbnco.com.au, with a subject line of Fibre Access Product. Next steps As part of the overall development of our commercial products, and the further definition of the network architecture, NBN Co is also developing a related - POI consultation paper, and a - Fibre Access Services (NFAS) Product Technical Specification - Fibre Access Services (NFAS) Pricing Guide Annexure A1 identifies the planned consultation and information release activities. Other related documents are in preparation, and will be published over coming months to form a suite of documentation: - Service Management and Operations Manual - Deployment Guide - Systems Manual The NFAS Products described in this Product Overview are available to retail and wholesale service providers to deliver services to end-user premises. A glossary of acronyms and abbreviations is included in the Glossary of Terms Section in Annexure A2. In a number of places in this paper, NBN Co has provided details of the speeds at which the NBN or a particular wholesale product offering is capable of operating. However, it is important for acquirers of NFAS to recognise that the speeds actually achieved by an End-User will depend on a number of factors, including the terms of the retail broadband plan, the End-User s chosen hardware and their in-premises connection. Page 4

7 1.1 Benefits The NFAS product offering will provide wholesale Ethernet access services with the following characteristics: High Speed Broadband Access NFAS provides high speed, high quality Ethernet access broadband services at speeds up to 1Gbps to meet the present and growing future needs of consumer, small/medium enterprise and corporate/government markets. Flexible service access speeds and a component based product approach provide the maximum flexibility and utility to Access Seekers. National Footprint NFAS products are provided using Fibre to the Premises (FTTP) technology to deliver high speed access to 93% of premises in Australia. Access Seekers can be connected to a fibre serving network at the NBN Co Points of Interconnect (POI). This will ensure an Access Seeker can provide a ubiquitous retail offering together with certainty of the speeds that can be delivered over the access network. NFAS access speed is consistent across the NBN FTTP footprint and unlike some earlier access technologies, does not deteriorate as distance to the end-user premises increases. High Quality Service Management Access Seekers using NFAS will be supported by highly automated systems and processes for service ordering and provisioning, service assurance and reporting/billing. Quality online service reporting and management tools will greatly assist the end-user and Access Seeker service management and communication process during the service lifecycle. Service Migration NFAS services and support systems are designed to enable a predictable service migration process from existing copper based access services to new fibre based services. Rollout An indicative national rollout schedule will be published and updated from time to time to give Endusers and Access Seekers as much visibility as possible of the local rollout arrangements and timing to ensure maximum uptake and minimise service disruption.

10 2 Product Overview The NFAS product consists of a number of components which are used by Access Seekers as building blocks to provide an end-to-end service. NFAS represents the access network portion of the overall network chain and is used for delivering Access Seeker s applications and services, as illustrated in the ISP application environment, Figure 2.1. FIGURE HIGH-LEVEL NFAS ACCESS SERVICES USED FOR INTERNET CONNECTIVITY NFAS delivers an active wholesale network connection via one or more Ethernet Virtual Circuits from the NBN Co POI to the End-user premises within the NBN Co FTTP footprint. It delivers analogue telephony and/or Ethernet interfaces at the End-user s Premises. Access Seekers can interconnect at designated NBN Co POIs which serve defined geographical Fibre Connectivity Serving Areas (FCSA) via Connectivity Virtual Circuits (CVC) as shown below in Figure 2.2. FIGURE NFAS NETWORK CONNECTION ARCHITECTURE Page 8

11 2.1 Key Wholesale Product Components The initial offering will be an Ethernet Bitstream product. It will consist of four key product components two physical and two logical network bandwidth elements. Access Seekers can build service offerings with significant flexibility using this component approach. The components are illustrated in Figure 2.3 which depicts the active network elements at the end-user premises and the Connectivity Serving Area, and the virtual circuits which connect the key active network elements. FIGURE LOGICAL NFAS NETWORK DELIVERY COMPONENTS User Network Interface (UNI) The UNI is depicted as product component 1 in Figure 2.3. It is the physical interface at an Enduser s premises and represents the NFAS network boundary. NBN Co will provide a NTU device which offers a number of UNI ports through which an Access Seeker can deliver services. An End-user may receive services from multiple Access Seekers simultaneously. An Access Seeker is able to deliver multiple services (for example, triple play) through a single UNI, or alternatively may elect to use multiple UNI. A UNI is uniquely allocated to an Access Seeker. Two types of UNI are provided: UNI-Data UNI-Voice Four independent 10/100/1000BaseT Ethernet ports are provided for data service delivery. Optionally, optical Ethernet UNI can be provided ie UNI-Data (1000BaseSX) and UNI-Data (1000BaseLX) At least one independent Analogue Telephony port is provided. This interface will utilise the SIP protocol for media signalling and can be interfaced with an existing Access Seeker SIP Softswitch infrastructure. Access Seekers can use these Page 9

12 interfaces to provide a migration path from traditional PSTN based telephony services. If two ports are provided both will be SIP Access Virtual Circuit (AVC) The Access Virtual Circuit (AVC) is the second product component depicted in the Figure 2.3. An AVC provides logical connectivity between a UNI at the end-user s premises and the Connectivity Virtual Circuit. Each Access Seeker wishing to deliver a service to a given End-user must order one or more AVCs. Each AVC can be ordered as Unicast or Multicast. Multiple AVCs can be mapped to a single UNI. AVC bandwidth is defined by the Committed Information Rate (CIR) and the Peak Information Rate (PIR). In the first release of NFAS there will be 7 defined PIR rates with the option to add incremental CIR bandwidth to support just-in-time and real-time applications such as voice and video Connectivity Virtual Circuit (CVC) The CVC is the third element depicted in Figure 2.3. It is the product component where many AVCs from End-users are aggregated together for presentation to the Access Seeker. The CVC provides logical capacity for connection of the Access Seeker network on the Network- Network Interface at an NBN Co Point of Interconnect (POI) to a Connectivity Serving Area. Each Access Seeker requires at least one CVC for each Fibre Connectivity Serving Area (FCSA) in which End-users are connected. The CVC is an aggregation element of the network and shields the Access Seeker from management of the NFAS infrastructure. This potentially allows the Access Seeker to achieve a higher utilisation and aggregation of backhaul. It allows for streamlining of backhaul providers, contracts, services and technologies, through the ability to use fewer, higher-capacity backhaul services, with greater control over contention and utilisation A given CVC is used to logically aggregate multiple end-users and is dimensioned by the Access Seeker. NBN Co may introduce minimum and maximum bandwidth rules on the CVC. Access Seekers may implement multiple CVCs in order to create a differentiated experience for particular end-user segments such as residential or business. The diagram Figure 2.4 illustrates the logical network configuration. The diagram illustrates that the CVCs are presented at a common POI for both residential and business End-users. Access Seekers may dimension the CVCs differently based on application and market requirements. Page 10

13 FIGURE MULTIPLE CONNECTIVITY VC (CVC) LOGICAL CONFIGURATION Network-Network Interface (NNI) The NNI is the fourth component of the NFAS product. It forms the physical service hand-off to the Access Seeker at each Point of Interconnect (POI). All End-user services in a given FCSA are presented to the Access Seeker at the POI via one or more Ethernet NNI. The NNI represents a physical aggregation where traffic is handed over to the Access Seeker and is delivered back to the Access Seeker s Point of Presence (POP) under whatever arrangements the Access Seeker has in place. Each NNI physically operates at either 1Gbps or 10Gbps and is available with a number of optical interfaces The NNI is offered in the following modes: Standard NNI Protected NNI A single physical interface is provided to the Access Seeker over which all NFAS services are presented. Multiple physical interfaces are provided which enable the Access Seeker to implement diverse equipment or backhaul. Physical interfaces are configured into NNI Redundancy Groups to implement either 1+1 redundancy or load sharing across ports, using IEEE802.3ad link aggregation. Page 11

14 2.1.5 Summary of Product Components and Relationships The following table provides a summary of the key NFAS product components and their context. Component Applies To Notes 1. User Network Interface (UNI) End-user 2. Access VC (AVC) End-user 3. Connectivity VC (CVC) 4. Network-Network Interface (NNI) Fibre Connectivity Serving Area Single or multiple Fibre Serving Areas The UNI provides physical handoff of Access VCs at an End-user premises. One or more UNI can be ordered by an Access Seeker. An Access Seeker can map one or more Access VCs to one UNI, but a UNI cannot be shared by multiple Access Seekers Each End-user will be served by a single or multiple AVC. AVCs can be ordered as Unicast or Multicast, and each AVC will be delivered to one UNI, although multiple AVC can be delivered to the same UNI of an Access Seeker. A Connectivity VC (CVC) aggregates multiple Access VCs back to the POI. The CVC is shared among nominated AVCs and allows the Access Seeker to manage network contention. The CVC connect to one Connectivity Serving Area. The NNI provides physical aggregation of several Connectivity VCs across a Fibre Distribution Region. It forms the physical handoff point to the Access Seeker at a POI and may be configured with redundant interface protection options. TABLE 2.5 KEY NFAS COMPONENT RELATIONSHIPS Page 12

15 3 Fibre Access Wholesale Product NFAS will offer one wholesale Ethernet Bitstream product with a variety of selectable features and functionality to enable Access Seekers to build Retail offerings in the residential, business, and enterprise & government markets. These include: Ethernet Bitstream Service Business features Interconnection Arrangements Class of service (COS) Telephony Capability Multicast Service OAM and Reporting 3.1 Ethernet Bitstream Service The Ethernet Bitstream product provides Access Seekers with a Layer 2 access service between the UNI on the NTU at an End-User Premises and the NNI located at the NBN Co POI. The logical architecture of the Ethernet Bitstream product construct is depicted in Figure 3.1 and shows the boundary within the End-User Premises that is known as the Wholesale Services Boundary (UNI), as well as the Access Seeker s POI network boundary (NNI). Within the initial release there will be seven bandwidth profiles based on Peak Information Rate (PIR) for the AVC. The base downsteam bandwidth will be 12Mbps, which will be consistent with the base downstream bandwidth of NBN Co satellite and wireless products. This will include 150kbps committed AVC capacity that can be either included in the AVC associated with the UNI-D or included as a separate AVC associated with the UNI-V to enable a standard telephony service. Downstream bandwidth up to 1000Mbps will be available on the NBN Co fibre network NBN Co will offer additional Committed Information Rate (CIR) speed increments up to an initial 100 Mbps per premises to support just-in-time and real-time applications such as video, voice and enterprise applications. Page 13

16 VLAN Tags The NFAS network will be designed to support network security and integrity to ensure secure delivery of services and support multiple End-Users. NFAS utilises a two-level VLAN addressing scheme to differentiate circuits, fully-compliant with IEEE802.1ad. A high level of security is achieved by including the NTU as part of the service it will not be possible for customers to connect directly to the fibre in the End-user s premises. Each AVC will be supplied as a separate virtual data stream within NFAS. The Tag structure uses an inner C-TAG to indicate an individual Access VC, to an NTU UNI-Data. The outer S-TAG indicates a Connectivity VC (which is specific to a FCSA). An example of NFAS planned VLAN tag assignment and usage follows: S-VLAN is used to designate the Connectivity Virtual Circuit from the Access Seeker to the Fibre Connectivity Serving Area. C-VLAN is used to designate the Access VC within the FCSA. The combination of S-VLAN and C-VLAN uniquely describes the EVC from the Access Seeker s network to the UNI at the End-user premises. S-VLAN tags will be unique within a POI, but may be re-used in other POIs. C-VLAN tags will be unique within the scope of a S-VLAN, but may be re-used between different S-VLANs. NBN Co will define and manage all tags unless VLAN transparency is enabled, in which case the business End-user C-VLAN tags are passed transparently through the NFAS network. Access Seekers will have the option of assigning VIDs at the UNI/NNI. 3.2 Ethernet Bitstream features for Business It is recognised that NFAS will be used as the access method of choice for many Access Seekers to build Wide Area Networks (WANs) offers for the enterprise market. As such NFAS will provide a number of enhanced features to enable this. Optical interfaces options on UNI-D Symmetrical CIR bandwidth from 10Mbps 1Gbps (for services higher than 100Mbps feasibility for Point-to-point deployment may to be considered) Multiple AVC support to a single UNI-D CE-VLAN Transparency options AVC protection options (specific design required) Page 14

17 Enhanced response and restoration SLA (up to 4 hour restore) An enhanced range of service provisioning and restoration options OAM and Enhanced reporting options (see section 3.7) 3.3 Interconnection Arrangements At each Point of Interconnect (POI), two options will be provided for Access Seekers to interconnect their infrastructure to the NFAS network platform. Passive Interconnection Facilities Access An Access Seeker requires only optical patching between the NNI and a backhaul service provided by a third party. An allocation is made at the Optical Fibre Distribution Frame (OFDF) at the POI. No facilities access is provided. An Access Seeker requires a physical presence in the POI facility for the purpose of housing transmission equipment related to the provision of backhaul. Physical accommodation and power is provided by NBN Co, and is ordered and supplied as a separate product from NFAS. Further information in Interconnection Facilities will be made available. 3.4 Class of Service (COS) The provision of end-to-end Class of Service (COS) is the responsibility of the Access Seeker to engineer and manage capacities, service policies, capabilities and tagging of different IP packets or Ethernet frames on the end-user UNI side of the Network Boundary and the Access Seekers NNI side of the POI. The Access Seeker applies the policy to its defined COS traffic classes in its network and interconnects this profiled traffic queue to collective end-users on the NFAS via the Connectivity VC at the POI. Two Classes of Service are offered with the initial release of NFAS: Traffic Class Typical Use 1 Control, critical and delay sensitive applications. 4 Data download / upload applications. Traffic Class 1 supports a Committed Information Rate with no excess information rate support, while Traffic Class 4 supports a Peak Information Rate with a Committed Information Rate set to zero. Page 15

18 Traffic Class 1 frames will be transmitted before Traffic Class 4 frames (ie. a strict priority queue). Additional Traffic Classes may be introduced in later releases of the product Further details on COS implementation will be available in the NBN Co Fibre Access Product - Technical Specification Congestion Management within NFAS Services Within an NFAS service, the Committed Information Rate (CIR) of Traffic Class 1 within an AVC is provisioned using reserved capacity. This results in deterministic performance for in-profile Traffic Class 1 traffic, under normal operating conditions. Out of profile traffic for Traffic Class 1 (ie. traffic sent in excess of the CIR) will be discarded. For all Traffic Classes, traffic sent in excess of the PIR of that traffic class will be discarded. 3.5 Telephony Capability NFAS will facilitate the delivery of a telephone service via an analogue telephony port (UNI-V) on the NTU by an Access Seeker. This capability is provided via an internal SIP based Analogue Telephone Adapter (ATA) and access is via the UNI-V interface. The UNI-V supports the following features where the Access Seekers softswitch supports this function, for example: Call Waiting Calling Number Display Call Blocking (Calling Number Blocking) UNI-V supports G.711 A-law voice coding. This will enable most legacy telephones to operate with the Access Seeker s IP telephony softswitch without having to change existing telephone equipment to an IP telephony handset. If required, local number porting of the end-user telephone number from legacy networks will be the responsibility of the Access Seeker. NFAS also supports Voice over IP (VoIP) natively within the AVC via a UNI-D. Thus the Access Seekers may deliver VoIP solutions from softswitch infrastructure to end-users with VoIP-compatible handsets and /or personal computers. The NTU will be able to accommodate an optional backup battery capability (ie a power supply unit capable of supporting a battery). NBN Co will not supply, install or maintain a backup battery. The ongoing supply and management of batteries will be handled by the telephony Access Seekers as will treatment of monitoring information provided by NBN Co by way of an optional service when power is not being supplied to the NTU. It will be up to Access Seekers whether they choose to acquire this service. However, NBN Co recommends that Access Seekers notify End-Users of its availability. Page 16

19 The support of Priority Assistance and Life-Line services are under consideration. NBN Co will provide an update of its position on these services as soon as possible 3.6 Multicast Multicast is a technology whereby content transmitted simultaneously to two or more End-users is carried as a single stream as far into the network as possible before being replicated (i.e. divided) and on-forwarded to end-users. Replication may occur at more than one point along the end to end path, resulting in a tree of replicated streams. The multicast technique can achieve significant bandwidth savings for the delivery of one-to-many services ensuring efficient use of the NBN capacity and Access Seekers backhaul, enabling a more cost effective delivery of services such as IPTV to a wide customer base. The example shown in Figure 3.4 depicts four End-users, each receiving a 10Mbps video stream. Multicast enables the Access Seeker to inject that stream only once at the POI. Without multicast, the Access Seeker would need to inject the same stream four times at the POI (consuming 40Mbps of bandwidth). An Access Seeker is free to scale the number of End-users they can support, without incurring additional CVC and backhaul expense. FIGURE MULTICAST REPLICATION The NFAS Multicast solution consists of two components: Multicast Domain Multicast Access Virtual Circuits Page 17

20 NFAS Multicast Domain Multicast Access Virtual Circuit Multicast Dimensioning Example The NFAS Multicast Domain enables Access Seekers to efficiently distribute content from a POI by injecting traffic only once at the Point of Interconnect (POI) irrespective of the number of end-users. NBN Co will manage the distribution of content to each OLT within the FAN(s). Access Seekers will define a series of Multicast Groups for each POI. In the context of IPTV, each Multicast Group represents one simultaneous channel of content. Charges are based on the aggregate Multicast bandwidth per POI and directly relate to the channel line-up offered by the Access Seeker. Access Seekers must order a Multicast Access Virtual Circuit for each End-user who wishes to receive Multicast content such as IPTV. This is an additional AVC to an AVC being used by the same Access Seeker for Broadband services. Multicast AVCs can be ordered at specific bit rates to suit the type of content being delivered (for example, Standard Definition or High Definition). This is a separate and dedicated AVC for multicast i.e. unicast traffic such as VOD or internet cannot be delivered on this service. In the context of IPTV, each Multicast AVC needs to be dimensioned at the required simultaneous viewing capacity that is to be provided to the End-user. The Access Seeker has a channel line-up as follows: 20 x Standard Definition 5Mbps per channel = 100Mbps 5 x High Definition 10Mbps per channel = 50Mbps The Access Seeker would order a Multicast Domain to satisfy the total channel line-up bandwidth of 100Mbps + 50Mbps = 150Mbps. End-user Multicast Access VCs (M AVC) would be ordered based on the number of channels to be delivered simultaneously. For example: Single Set Top Box package Dual Set Top Box package Standard Definition only package = 10Mbps M AVC. = 20Mbps M AVC. = 5Mbps M AVC. Page 18

21 3.7 Service OAM and Reporting Service OAM The NFAS product offers enhanced Service Operational, Administration and Maintenance (Service OAM) features using capabilities based on IEEE802.1ag (Connectivity Fault Management). NFAS Service OAM provides a level of operational integration across the NFAS service boundaries that allows NFAS services to appear functionally on-net to the Access Seeker. These features allow an increased level of visibility into the status of NFAS services, and provide diagnostic capabilities that assist in the rapid identification and isolation of faults. NFAS Service OAM is expected to appeal to Access Seekers who use NFAS to address the business market, and require a higher level of network monitoring and control for delivering premium applications. Reporting The NFAS network offers enhanced reporting for selected services. This extended reporting builds upon the base level of statistics, providing further information around traffic management and discard at the Class of Service level. These metrics help an Access Seeker monitor their congestion and traffic management within the NFAS network, to ensure preservation of their own IP-level, end-to-end QoS policies. This will appeal to Access Seekers who offer mixed-media applications across the NFAS network (e.g. tripleplay), who are expected to take advantage of the NFAS Class of Service mechanisms. Page 19

27 5 Service Management NBN Co s system architecture is built around the key principles of Service Provider enablement and automation. By placing the management controls of each End-user service in the hands of the corresponding Access Seeker, operational overheads and manual order processing are minimised. NBN Co system interfaces will span across a number of different domains as shown below. FIGURE 5.1 SERVICE MANAGEMENT DOMAINS Details will be provided in the Service Management and Operations Manual and the Systems Manual. 6 End-user Premises NBN Co will provide a Network Termination Unit (NTU) at each end-user premises. Further details will be provided in the Deployment Guide. Page 25

28 7 NBN Co Fibre Access Service (NFAS) Configuration Examples The following examples illustrate NFAS use in the typical delivery of residential and business applications offered by Access Seekers. They outline both equipment and service configuration arrangements, and how components of NFAS can be utilised in varying service delivery environments. 7.1 Residential Gateway The NTU connects to End-user equipment, typically via a Residential Gateway, which maintains the Access Seeker IP address required for the network connection. Figure 7.1 shows voice connection via the gateway. Traffic classes (TCs) are illustrated, terminating on a single NTU port. FIGURE RESIDENTIAL GATEWAY The Residential Gateway illustration shows residential connection for voice, video and data and the gateway CPE is the responsibility of the End-user or the Access Seeker. The selection of gateway equipment will be determined by the Access Seeker and End-user, depending on the Access Seeker retail service model and feature requirements. Page 26

29 7.2 Legacy Voice and Virtual Circuit Dimensioning A legacy POTS equivalent service, utilising existing in-house telephony wiring is illustrated in Figure 7.2. The Access Seeker provides an equivalent standard telephone service using the inbuilt NTU ATA capability. FIGURE 7.2 LEGACY VOICE SERVICE DELIVERY (FROM NTU) In this scenario, the voice service will be delivered from the NTU s analogue POTS port (ATA). The Access Seeker will need to undertake the following typical tasks to equip the NFAS product to provide voice services: Provision a Connectivity VC between the Access Seekers NNI and the connectivity Serving Area the Access Seeker s End-user is located. Provision an Access VC to the End-user premises at a sufficient bit-rate to carry one channel of voice (150kbps in this example). Enable the NTU POTS port, and configure the NTU SIP stack to communicate with the Access Seeker soft-switch and media gateway infrastructure. Once the new voice service is ready and tested, the Access Seeker will migrate the End-user s existing voice service to NBN, which will consist of the following: Connect the End-user s existing premises telephony cabling to the NTU POTS port. Initiate porting of the End-user s existing PSTN number as per the established Local Number Portability process If required, cancel the existing legacy voice service with the existing carrier. Premises cabling changes or upgrades are the responsibility of the End-user or Access Seeker. Page 27

30 The diagram in Figure 7.3 illustrates a possible approach to dimensioning upstream bandwidth requirements at the Connectivity VC taking into account the statistical nature of telephone calling and the potential for network efficient concentration or contention of the provisioned bandwidth at the Connectivity VC. FIGURE DIMENSIONING OF VOICE TRAFFIC This example illustrates the relationship between Access VC and Connectivity VCs for an Access Seeker provided voice service to End-users located in a Connectivity Serving Area. AVCs are dimensioned at 150kbps for each UNI voice port. Based on calling patterns of 100 End-users, 3Mbps of CVC capacity is provisioned, effectively contending the access capacity 5:1. Page 28

31 7.3 Legacy Voice and Basic Broadband replacing existing xdsl CPE The application illustrated in Figure 7.4 is the typical high speed internet broadband and voice service. It supports broadband High Speed Internet Access, Internet Video (e.g. YouTube, ABC iview), and standard OTT applications. The Broadband service is equivalent to today s ADSL/ADSL2+ speeds and throughput. FIGURE 7.4 LEGACY VOICE AND NEW BROADBAND SERVICE An Access Seeker providing this configuration would need a two access service with appropriate traffic classes to support voice and data services. It is recommended that the data service be TC-4 best effort while voice should be provided as the premium traffic class, TC-1. Premises cabling is the responsibility of the End-user or Access Seeker, but may affect service performance. Page 29

32 7.4 Access Seeker UniCast Internet Protocol TV Services IPTV services can be delivered over the NFAS network as over the top services. Figure 7.5 illustrates the service environment. IPTV and VoD services can be delivered to the user residential gateway or set top box as part of the normal High Speed Internet Access, service IP data bitstream by an Access Seeker with the appropriate content serving infrastructure.
