This case study details the collaboration between AllPoints Fibre Networks (APFN) and AVSystem to develop a multi-tenant Auto Configuration-as-a-Service (ACS) model aimed at transforming wholesale broadband service delivery in the UK. The document outlines how this innovative model allows Internet Service Providers (ISPs) and Managed Service Providers (MSPs) to manage Customer Premises Equipment (CPE) at scale without the need for their own infrastructure. It describes the integration of AVSystem's Cloud ACS with APFN's aquila platform, enabling service providers to automate CPE provisioning, updates, and diagnostics through a unified interface. The study highlights the operational benefits, including reduced costs, faster scaling, and improved customer experiences. Additionally, it discusses the future-ready foundation of the service, supporting both TR-069 and TR-369 standards for next-generation device management. Overall, the case study presents a significant advancement in the efficiency and effectiveness of broadband service operations.
