We are Grandfathering ADSL (Basic UBA) on ISAM DSLAMs to level 1 from 1 March 2018. This change was first communicated in November and was originally intended to be implemented on 1 February 2018 but as we have experienced delays, we will now apply this from 1 March 2018.

What’s changing

Grandfathering level 1 means:

• No new customers may obtain the product
• Existing customers can keep the instances of the product they already have
• If an existing customer moves they cannot keep the product
• Existing customers cannot order more instances of the product

To facilitate this change we will be updating our processes and any orders placed on or after 1 March 2018 will be rejected and you will received a message stating “BUBA is no longer available at this address”.

Alternatives to ADSL on ISAMs are ADSL2+ (Enhanced UBA) and VDSL (WVS) which offer better performance for the same monthly rental.

Supporting details

ADSL is in the mature stage of the product lifecycle and is delivered over the legacy ATM platform. ISAM broadband equipment also supports ADSL2+ (Enhanced UBA) and VDSL.

ADSL remains an option where it’s the only broadband available (ASAM and Conklin DSLAMs connected to the legacy ATM network).

It is not mandatory to move your customers at this stage, however there is a very straightforward migration process and it provides an ideal opportunity to discuss better broadband services with your customers.

Next steps

If you have any queries or wish to discuss migration options, please contact your service delivery manager.
