BUBA is an early version of UBA where the handover uses Layer 2 Tunnelling Protocol (L2TP). We are withdrawing the old L2TP network technology and as a result need to migrate BUBA customers to better performing EUBA0, either ADSL or VDSL. You should also consider migrating your customer to fibre services where they are available.

This update provides a 12 month notice of the withdrawal of L2TP based BUBA handovers.

What’s the detail?

BUBA is an early version of UBA where the handover uses Layer 2 Tunnelling Protocol (L2TP) and therefore requires you to have a L2TP Network Server (LNS).  Please refer to the “Basic UBA product user guide” for more details.

We are withdrawing the L2TP platform and as a result need to upgrade customers to Enhanced UBA (EUBA0) which supports ADSL1, ADSL2+ and VDSL.

This migration is an opportunity for you to upgrade customers to ADSL2+ (line speeds of up to 20/1Mbps) or VDSL2+ where available (line speeds of up to 70/20Mbps or if vectored VDSL up to 130/20Mbps). Actual performance will depend on the customers’ modem, premises wiring, distance of customer from Chorus equipment and service provider network.

You should also consider migrating you customer to fibre services, where they are available, providing line speeds of up to 1000Mbps.

BUBA connections delivered over L2TP Handover connections will no longer be available from 1 November 2020.

Next steps

All BUBA connections that are delivered over L2TP Handover connections to be migrated to an alternative solution by 1 November 2020.

To facilitate this change we will be offering, at no cost, a managed migration service to migrate to EUBA0, either ADSL1, ADSL2+ or if available VDSL2+.
