Page 5: Introduction
With Enhanced UBA you can provide your customers with a range of own-branded, broadband enabled services and applications such as voice over internet protocol (VoIP) and internet access. The Basic UBA variant EUBA 0 can be found described in this product user guide. 2 Benefits 2.1 Key benefits of Enhanced UBA: ... - Page 6 Enhanced UBA is an intermediate input service that you can combine with your own network, or other services, to provide a range of own-branded broadband enabled services and applications such as voice over internet protocol (VoIP) and internet access. It is designed to serve your customers with either single or multiple access devices such as computers, consoles or telephones.

4.2 Enhanced UBA access Enhanced UBA consists of a DSL data connection from the ETP at your customer’s premises to the DSLAM at the local exchange or cabinet. While Enhanced UBA is optimised for ADSL2+, it is possible to use ADSL1 modems (see section 11 ‘end... -
Page 8: Local Aggregation Path
In the context of Tail Extension a Remote handover point is an EAS located in a coverage area which is not the coverage area in which the Enhanced UBA access tail is provided. If you don’t have the ability to hand over traffic at the local handover point you can purchase Tail Extension (or another backhaul service) to take the Enhanced UBA traffic to a remote handover point that you’ve nominated. -
Page 9: Variants Of Enhanced Uba
Enhanced UBA 90 is suitable for G.711 codec. All four variants of Enhanced UBA can be provided with a voice service, such as Baseband. However, the Baseband Copper and Baseband IP services are not provided as part of the Enhanced UBA service and are as defined in the Baseband Service Description and product user guide. -

Page 11: Tail Extension
PPPoA modem support is an optional feature provided in accordance with the WSA. 6.4 Tail Extension Tail Extension is a backhaul service that extends an Enhanced UBA access tail from the local handover point to a remote handover point that you’ve nominated. For more detail on how Tail Extension works refer to section 4.6. - Page 12 These service specifications are design targets and should be used by you when developing end-to-end real time and best efforts applications. However the Enhanced UBA service will likely only form a small part of any such end-to-end application. Actual performance is not guaranteed as it is subject to external influences.

If you do not wish to (or are unable to) collect Enhanced UBA traffic from the local handover point and would like to transport the traffic to a remote handover point where you have already established a handover link, you may do so using one of the following: •... -
Page 14: Geographic Availability
The location of handover points and related coverage areas may change in the future as the ADSL2+ network is rolled out. Please refer to Clause 17.1.4 of the UBA STD Operations Manual for more detail on our obligation to notify changes to coverage. -
Page 15: Relationship With Other Products
8.3 Relationship with other products Enhanced UBA can be combined with a number of Chorus input products, such as handover links, UBA Backhaul, and Commercial Colocation. You can choose to use Enhanced UBA with or without Tail Extension. Enhanced UBA traffic can also share a handover link with High Speed Network Service (HSNS). -

Each Enhanced UBA access tail connection is carried over dedicated VLANs from your customer’s... - Page 20 Our network will translate the 802.1q VLAN ID to the 802.1ad identifiers. • The Enhanced UBA VLAN will support both best efforts traffic and real time traffic as long as that traffic is tagged correctly. Incorrectly marked traffic, including no markings at all, will be discarded.
- Page 21 If their LAN is not using 802.1q then the modem or gateway must tag the traffic according to the appropriate class of traffic. The figure below shows the format of the Ethernet frames for tagging Enhanced UBA traffic: Figure 11: Enhanced frames format Tag protocol identifier (TPID) is a 16 bit field containing the Ethertype.

Note: across multiple handovers for the same service provider there may be replication of S-VIDs on different handovers. 9.4 Traffic Management The Enhanced UBA service specifications for real time and best efforts traffic are managed through our network through a number of traffic management techniques, as shown below:... - Page 23 2 full length frames and a 200 byte VoIP packet to be sent without discard. At an aggregate level the Enhanced UBA traffic is managed as following: • All real time traffic is aggregated per service provider and strictly prioritised over the local aggregation path.

• PPP over Ethernet (PPPoE). This would be supported by many legacy and current generation devices utilised to deliver Basic UBA services, as well as many L2TP gateways. However, you must ensure these devices support priority-tagging and 802.1Q VLAN marking of the Ethernet frames. -

This Port ID is independent of the ASID or SVID/CVID (VLAN identifiers) although there will only be a 1:1:1 mapping between these values. The Port ID is returned in the OO&T order request for the service. Port IDs will change if the physical port changes, e.g. under some fault conditions, change addresses and cabinetisation (when the end customer is moved to a new DSLAM). -

‘leak’ between end customers. Since each end customer uses the same 802.1q VLAN, which is then translated into a unique VLAN within the Chorus network, it is not possible for an end customer to spoof a neighbour’s VLAN. - Page 30 deliver a maximum 1500 byte IP packet from the end customer, or a 1492 byte IP packet carried over PPPoE. Note: that PPPoE is optional. 802.1 q (VLAN) settings: VLAN ID of 10 is required 802.1 p (Ethernet priority flags) settings: Best effort-class frames are tagged ‘0’.
