1GigE, 10GigE and 100GigE are available. UFB Handover connections provide 802.1Q and 1GigE, 10GigE and 100GigE are available. UFB Handover connections provide 802.1Q and 802.1p transparency (with up to 4093 service VLANs each with 4093 end user VLANs to be passed to the service provider). VLAN allocation is based on the access service on the UFB Handover connection (refer to the respective NGA service description for more detail).

For locations and availability please check the Operations Manual:

Note: 1GigE UFB Handover connections are not available at all locations.

To use a UFB Handover connection you must have the capability to access and interconnect with it by one of the following:

• Tie cable connecting the UFB Handover connection service to colocation footprints
• Footprints can be yours or third-party footprints
• Backhaul service that can be provided by you or Chorus or a third party
• Direct Fibre Access service (DFAS) to connect to your equipment at a remote location within the central office (exchange) area. 

UFB Handover Connection Diversity

10GigE and 100GigE Handover services supports multiple physical links for resiliency and 
capacity using Link Aggregation Grouping (LAG) in the following configurations:

Handover Configuration options

LAG Ports:

LAG allows multiple physical ports to be combined into a single UFB Handover Connection Service. 
In the event of the failure of one physical link, the traffic management rules apply. Only same speed
 links may be combined into a LAG group.

100GigE and 10GigE Card and Geo Diversity

Where 
(a) Standby links can be in same or different POI site but must be in the same POI area as the active link.
(b) All active links are provisioned on one card and all standby links are provisioned on a different card within the same node or on a different Chorus handover node. All ports must have the same interface rate (Except during bandwidth upgrades where dissimilar speeds are temporarily permitted).
(c) The active/standby status of links is controlled by Service Provider equipment using Link Aggregation Control Protocol (LACP)
d) For card diversity the standby links would be in a separate card but on the same node in the same POI site (aka Exchange). For geo-diverse connections, the standby links would be in a separate card on a separate node in a different POI site (aka Exchange), but in the same POI area (aka candidate area)

Handover Geo Diversity 

This feature introduces an additional level of resilience as it allows end-users to map to two geographically separated UFB handovers in the same candidate area ensuring that in the event of a failure for any one of those handovers, the customer can seamlessly switch traffic over to the other handover.

At this stage, UFB Handover geo-diverse service is available at the following pairs of the exchanges with more POI locations to be included in the near future: 

Service Exclusions  

1. Layer 1 services, such as DFAS, ICABS or BFAS
2. Chorus Connect and Chorus Datacentre Connect   
3. CRT
4. Copper services, including Basic Unbundled Bitstream Access (BUBA)
5. HSNS/HSNS Premium 

Handover Grooming offers:

• Supports Link Aggregation Group (LAG) rearrangements within a UFB Handover node.
• Provides more flexibility in the way you upgrade and expand Link Aggregation Groups where port capacity limitations occur on a card.
• Allows Handovers to be migrated between card slots for the purpose of capacity expansion or reconfiguration. E.g. 1Gbps to 10Gbps and 100Gbps upgrade or LAG expansion.
• Enabling a faster way of expanding capacity without having to remap each access
