Optimize Network Performance with D3.1Enhanced
In today’s challenging economic environment, it’s more important than ever to ensure your current HFC access cable network assets are fully optimized to provide maximum performance, speeds, and capacities.
Not all network optimization scenarios, though, are equally viable. And not all network architectures need to evolve at the same pace.
D.31Enhanced (D3.1E) is an economical way to monetize existing network assets while optimizing your network’s performance. A D3.1E deployment supports maximum throughput speeds of up to 8 Gbps in the downstream in targeted areas of your network, enabling you to increase ARPU and keep pace with your competition economically and efficiently. With D3.1E, you can get the most out of mid-split and high-split network upgrades without resorting to costly rebuilds or disruptive service outages.

D3.1E: An Introduction
D3.1E doesn’t require costly or extensive improvements or upgrades to your existing network. Instead, D3.1E uses DOCSIS 3.1+ or DOCSIS 4.0 CPE devices to expand downstream capacity and increase speed tiers to your subscribers’ homes in mid-split and high-split networks. Which CPE device you choose to deploy depends on your network upgrade plans:
- If you’re planning to operate a DOCSIS® 3.0 or 3.1 network for the foreseeable future, then you can deploy DOCSIS 3.1+ CPE devices
- If you’re planning to upgrade your network to support DOCSIS 4.0 operation, then you can deploy DOCSIS 4.0 CPE devices in your current network (after equipping them with the proper diplex filters and/or switches) and future-proof your network for full DOCSIS 4.0 deployments
Both types of CPE devices utilize advanced chipsets that support up the bonding of 4 OFDM channels and 32 SC-QAMs in the downstream path and five OFDM channels (without SC-QAMs) in mid-split and high-split networks, whereas previous generation DOCSIS 3.1 CPE devices supported only two OFDM channels and 32 SC-QAM.

Speed and Capacity Gains
D3.1E enables significant gains in downstream speed and capacity over standard DOCSIS 3.0 or DOCSIS 3.1 network operation, though results will vary based on bandsplits, CMTS configurations, and other factors. You’ll realize the most significant gains in downstream performance with mid-split and high-split bandwidths.
D3.1E CPE devices support the bonding of up to four OFDM channels and 32 SC-QAMs in 1 GHz and 1.2 GHz mid-split networks and a maximum of five OFDM channels (without SC-QAMs) or four OFDM channels and 32 SC-QAMs in 1.2 GHz high-split networks. The additional OFDM channels are bonded from existing CMTS and/or Remote MAC-PHY equipment. The devices also support a maximum of two OFDMA channels in the upstream.
Flexible and Cost-Effective
By deploying D3.1E, you can leverage your existing network assets to improve performance and expand your service offerings—and, at the same time, extend the life of your current network. D3.1E requires only minimal upgrades to inside and outside plant equipment, providing a path to better network performance and downstream speeds without incurring exorbitant construction, labor, and equipment costs. You can use the flexibility of D3.1E to monetize your current network assets, maintain competitive value proposition with your subscribers, and get the best return on investment from your field upgrades. For example, your current DOCSIS 3.0 or DOCSIS 3.1 E6000 CERs deployments can support D3.1E operation, providing you with an excellent strategy for extending the life of your headend assets. CommScope’s E6000® Release 13 includes enhanced features for D3.1E operation, including support for DOCSIS 4.0 CPE devices running in D3.1E mode. Release 13 also features expanded OFDM channel bonding capacity to support expanded downstream bandwidth in D3.1E deployments. E6000 Release 13 also supports Distributed Access Architecture (DAA) Remote PHY operation, making it an ideal choice to future-proof your network for next-generation technologies. If you’re operating the C100G or the CommScope vCMTS—recently added to CommScope’s product portfolio after the company’s acquisition of the cable business unit assets of Casa Systems—upcoming software releases for both platforms will support D3.1E operation. C100G Software Release 8.12 will support four OFDM channel blocks and two OFDMA channel blocks for D3.1E deployments and will also provide support for DOCSIS 4.0 CPE devices running in DOCSIS 3.1 mode. CommScope vCMTS Software Release 10.8.2 will support these same D3.1E features on a virtual platform. For the outside plant, CommScope offers mid-split and high-split frequency split upgrade kits for your portfolio of amplifiers and nodes, providing an easy and economical upgrade path for fielded actives currently operating in sub-split networks — and full support for maximum downstream capacity and throughput gains in your D3.1E deployment. |
Optimized Network Performance
D3.1E doesn’t just expand downstream capacity and increase speed tiers available to subscribers. It also helps to optimize network performance. You can leverage D3.1E to enhance the operational capabilities of your current network, better utilize network operations and field services, and improve subscriber satisfaction. As the cable industry begins deploying next-generation network technologies, such as DAA, Node PON, and virtualized headend operation, many MSOs have begun planning to replace legacy MPEG QAM video channels with IPTV. By eliminating these legacy channels, you can reclaim either six or eight MHz per channel in the downstream band, depending on your current channel configurations. You can reassign this reclaimed bandwidth to a third, fourth, or fifth OFDM channel, depending on your D3.1E network configuration—something not possible with standard D3.1 CPE devices, which only support a maximum of two OFDM channels. OFDM operation can help improve the performance of CPE devices in the home and provide better subscriber experiences. OFDM operation supports multiple modulation profiles, which more efficiently allocate bandwidth to all CPE devices in the downstream path. And there are various solutions to automate operation with OFDM channels and enable the distribution of downstream signals at the maximum modulation levels available to all CPE devices, providing optimal OFDM support and maximum D3.1E performance. Many next-generation DOCSIS 3.1+ or DOCSIS 4.0 CPE devices feature improved or enhanced Wi-Fi® features that further support a transition to IPTV. Next-generation D3.1 Gateways, for example, may feature the latest dual-band or tri-band Wi-Fi 7 capability. Wi-Fi 7 supports accelerated through-put, reduced latency, and better reliability for improved performance with connected devices throughout the home network. |
