Remote PHY Interoperability testing reaches a new level with the CCAP Core Simulator by VECTOR TECHNOLOGIES


The CCAP Core Simulator allowing the testing of the Remote PHY Device (RPD) for compliance with the Remote PHY Specification is ready to implement. The Cable MSOs will have ability to facilitate the interoperability validation process.

As a result, they can achieve full interoperability of any Converged Cable Access Platform (CCAP) Core, Remote PHY Device (RPD) and Cable Modem (CM) by carrying out tests using the CCAP Core Simulator platform. VECTOR TECHNOLOGIES development will maximize the MSO’s business efficiency and profitability in transforming their cable access networks towards Distributed Access Architecture (DAA).

Over the last few months VECTOR TECHNOLOGIES has participated in the OpenRPD initiative and Remote PHY interoperability events at CableLabs. To take full advantage of the laboratory environment, VECTOR TECHNOLOGIES developed its own software based validation platform – CCAP Core Simulator (CCS).

“Working closely with multiple vendors in the laboratory environment and gathering their feedback is essential for future Remote PHY development,” said Maciej Muzalewski, CTO of VECTOR
TECHNOLOGIES. “At this stage the CCS will facilitate and improve the validation of RPD compliancy with the standards. In the next few years MSOs will be deploying hundreds of CCAP Cores and thousands of RPDs in their network. Therefore, the interoperability between multiple vendors should be one of the main objectives in the long term. The purpose of our solution is simple: help the cable MSOs to achieve an interoperable and reliable solution as quickly as possible. This will ensure there is a clear path to evolve their Next Generation Access (NGA) networks and to reduce the investment costs.”

The CCS platform emulates the CCAP Core with all logical functions required for appropriate RPD operation, while fully complying with the MHAv2 set of specifications. Due to this software-based solution, the CCS will in the future enable fast adaptation to the Full Duplex DOCSIS 3.1® technology and any changes implemented in the MHAv2 set of specifications. Communication based on 10GE symmetrical streaming will revolutionize HFC networks in terms of quality provisioning services.
