MSO Access Network – Distributed Access Architecture (DAA)

Leading Path brings you the right engineering and deployment management resources who seamlessly fit inside your organizations working together side-by-side on system integration, UAT, deployments to make your MSO Access Network DAA program successful!

Over the last decade, Internet traffic has grown at unprecedented rates. Networks are in a constant state of rebuild to keep pace with demand. With the continuous creation of new and innovative ways to consume content, this growth trend shows no sign of slowing down. Multiple Service Operators (MSOs) have had a significant speed and flexibility advantage over the traditional telecommunications companies for many years due to the robust nature of Hybrid Fiber Coaxial (HFC) Networks. While these networks continue to provide a quality customer experience (and will likely continue for many years to come), there is a need to evaluate next generation architectures to ensure the customer access networks can continue to grow for many more years to come.

Remote PHY is an HFC technology that leverages digital ethernet fiber connectivity directly to the node. In an R-PHY topology, the Edge QAM (PHY) is put into the Remote PHY Device (RPD) which resides inside the node and closer to the customer.  IP replaces RF to connect the headend to the access nodes.  The Physical Layer Converged Interconnect Network (PLCIN) equipment connect the CMTS cores to the RPDs.

Remote OLT (ROLT) is an EPON technology that also leverages digital ethernet fiber connectivity directly to the node. In an ROLT topology, the MAC and PHY of the OLT device resides inside of the node, decreasing the fiber distance to the customer while allowing for greater distance between the OLT and the northbound router.


Our Mission is to fulfill these needs by bringing staff and consulting expertise to the operators and their key joint ventures. Leading Path partners have more than 20 years inside the nation’s largest MSOs, inside the research and test labs, out in the field, part of the inter-ops, inside the operations supporting from the beginning. We work with you to leverage our networks, staffing specialists, consultants and get you the teams you need to be successful. Historically we have been part of some of the largest MSO developments performing QA & test engineering, field trials, deployments, and staff augmentation for the most important industry initiatives. Our expertise comes from the inside-out, deeply focused on supporting the MSO.
