CommScope DOCSIS Architectures successfully interoperates with DOCSIS modem vendors
CommScope , announced that all four of its major DOCSIS Access Architectures have successfully demonstrated interoperability with five DOCSIS 4.0 modem vendors . All four architectures , which are out of CommScope ’ s Access Network Solutions segment , proved interoperability during two inaugural Interop · Labs DOCSIS 4.0 Technology events hosted by CableLabs and its subsidiary , Kyrio , during the weeks of July 17 and August 14 , 2023 .

The primary goal of this interoperability event was to test whether new DOCSIS 4.0 modems , that utilise longer certificates for encryption per the DOCSIS standard , would register and properly provide high-speed data service on Cable Modem Termination Systems , CMTSs that only support up to DOCSIS 3.1 technology .
A secondary goal of the event was to determine if DOCSIS 3.1-capable CMTSs demonstrate higher downstream speeds with DOCSIS 4.0 modems over what can be achieved only with DOCSIS 3.1 modems . Such a configuration is a hybrid DOCSIS 3.1 , 4.0 which begins to harness the improved capabilities provided in the DOCSIS 4.0 technology .
In a blog post , Doug Jones , Principal Architect with CableLabs , noted " The DOCSIS systems we investigated passed high-speed traffic . Very high speed , as in gigabits-per-second downstream and upstream . For me , a long-time DOCSIS expert who still remembers dial-up speed , DOCSIS 1.0 speeds and everything since , it really was quite amazing to witness the speeds that DOCSIS 4.0 technology makes possible . This included DOCSIS 3.1 CMTSs augmented with additional channels to support DOCSIS 4.0 modems .”
“ CommScope is proud to have demonstrated DOCSIS 4.0 modem interoperability with all of the major DOCSIS 3.1 CMTS architectures , both centralised and distributed ,” noted Guy Sucharczuk , SVP and President , Access Network Solutions , CommScope .
“ Demonstrating the highest industry speeds with our vCore , vCMTS solution with DOCSIS 4.0 modems was especially notable . This is a significant step forward for CommScope and the industry , and it is a showcase for how CommScope is equipping the world ’ s operators for the 10G future .”
CommScope demonstrated interoperability in the hybrid DOCSIS 3.1 , 4.0 configuration across all four major DOCSIS 3.1 architectures : I-CCAP , Remote PHY with vCore , vCMTS , Remote PHY with a physical CCAP Core , and Remote MACPHY . CommScope was able to achieve this with a combination of products , including its industry-E6000 Converged Edge Router , CER , which can be deployed as an I-CCAP , a CCAP Core for Remote PHY , eCore operation , or as hybrid I-CCAP , eCore , meaning both architectures in the same chassis .
CommScope also utilised its highly flexible RD2322 RxD device , which can operate as either a Remote PHY Device or Remote MACPHY Device with a field-deployable software upgrade . In addition , CommScope introduced its vCore Virtual CMTS , vCMTS product , which achieved speeds of approximately 8.7 Gbps downstream and 1.4 – 1.5 Gbps upstream .
CommScope has demonstrated how operators can leverage CommScope products to navigate the path to 10G with any architecture that is the best fit for their current requirements , along with the flexibility to change course if needed . p
