CommScope Demonstrates its DOCSIS 4.0 Modem Interoperability at CableLabs on All 4 Major CMTS Centralized & Distributed Access Architectures

CommScope Architectures successfully
interoperated with five DOCSIS 4.0 modem vendors with the
Integrated Converged Cable Access Platform (I-CCAP), Remote PHY
with Virtual CCAP Core (vCore / vCMTS), Remote PHY with Physical
CCAP Core, and Remote MACPHY
CommScope (NASDAQ: COMM) announced today 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 utilize 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.
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-leading 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 utilized 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. The demonstrated
interoperability is notable as it highlights CommScope’s ability to
leverage its robust, feature-rich, and field-hardened DOCSIS Media
Access Control (MAC) and application software across all four major
DOCSIS 3.1 access architectures with a similar feature set and
capability. Operators who have already deployed any of these
architectures can take advantage of these advanced capabilities
through a surgical application of DOCSIS 4.0 modems, for
subscribers who order the highest tiers of service, without the
need to upgrade the entire network. CommScope estimates the DOCSIS
3.1/4.0 hybrid configuration can be utilized to offer up to an 8
Gbps downstream service tier; this offers a cost-effective bridge
for operators to provide higher speed services ahead of fully
deploying 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 centralized 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 leading
operators for the 10G future.”
