Connect Broadband Access Controller

Connect Broadband Access Controller is an industry-leading PON software based on ONF’s VOLTHA/SEBA. This innovative software provides a scalable architecture that allows each microservice to scale individually to handle capacity requirements. Simplify network operations with Connect Open Broadband’s flexible deployment options, open network design, and its microservices architecture. Implement zero-touch provisioning facilitated by its AI-based management capability. Sharpen fault detection and isolation with centralized management. Connect Broadband Access Controller is an agile software solution to transform your fiber network.

Flexible Control Options

Flexible deployment options enable you to transform your network in the most optimal manner. Per our analysis, the optimal deployment model for a very rural environment would be to use the distributed, while for extremely urban environments it would be the centralized deployment model. This allows service providers to choose the optimal model to meet current and future customer needs at the lowest cost/GB.

  • Our Distributed Control Plane deployment option enables you to transition to an open architecture and achieve greater control; better suited to rural, low-density deployments, this option only requires a change in the OLT.
  • Our Centralized Control Plane deployment option centralizes management and enables faster innovation cycles and uniform provisioning for urban, high-density deployments.
