Telefonica disaggregates broadband network with Radisys solution

Radisys Corporation announced that Telefonica is disaggregating its broadband network with Radisys’ Connect Open Broadband portfolio to achieve more network flexibility and programmability, and to reduce the risk associated with supply chain shortages.
Telefonica’s 5G network in SpainRadisys’ Connect Open Broadband comes with hardware and software components, including white-box Combo-PON OLTs, the Connect Broadband Access Controller (CBAC), and the Radisys Management System (RMS) software.

Telefonica and Radisys will deploy the technology in a live network supporting residential and enterprise customers in 2023. The deployment means that Telefonica will be able to mix and match components from multiple vendors and multiple supply chains which helps lower total cost of ownership while also mitigating supply chain risk associated with a proprietary solution.

Telefonica is transitioning from legacy chassis-based OLT equipment to new solutions, where Radisys’ white-box OLTs with software-defined networking control to advance its telco cloud capabilities and achieve greater efficiency and automation.

This programmability allows Telefonica to use automation and Artificial Intelligence/Machine Learning in its network to accelerate service innovation and new service introduction. Radisys’ hardware and software components integrate with Telefonica’s OSS/BSS, resulting in increased operational simplicity. It also supports zero-touch provisioning and greater programmability with SDN control.

Radisys’ open-standards-based Combo-PON OLTs support G-PON and XGS-PON within the same PON port of the OLT, allowing Telefonica to migrate subscribers to XGS-PON when needed and to scale its network.

“Telefonica partners with Radisys for deploying a disaggregated architecture to accelerate time-to-market and innovation while minimizing risks associated with supply chain challenges, enlarging the vendor map and guaranteeing business continuity,” said Daniel Cortes Olmeda, senior manager for Fixed Access, Telefonica.

“We are working with Telefonica to prove out the benefits of a disaggregated network in both urban and rural environments. Our solution offers flexibility and scalability for all fixed broadband scenarios,” said Harris Razak, head of Radisys’ Broadband Access Business.
