Broadcom Announces Multi-Line DSL Terminal Solution

February 16, 2018

Broadcom Corporation today announced a new chipset, production-ready reference design platform and associated firmware that is targeted for Ethernet-based wireless and wired backhauling applications, as well as Ethernet-based business applications that require higher bandwidth.

The new Broadcom® BCM96519, the industry’s first and most compact multi-line digital subscriber line (DSL) terminal solution, leverages Broadcom’s high performance multi-mode ADSL2+/VDSL2, vectoring and channel bonding technologies.

Compared to existing copper-based transport and backhaul systems in the market today, the BCM96519 significantly increases the capacity of Ethernet connectivity over copper, almost 10-fold, with rates approaching 1 Gigabit per second (Gbps) speed.

Highlights/Key Facts:

•Broadcom’s new BCM96519 multi-line DSL terminal solution provides wireless service providers with fast, simple and cost-effective upgrades to multi-Megabit per second (Mbps) backhauling links supporting 3G and 4G base stations, or Node Bs (also known as BTSs or base transceiver stations) to accelerate the introduction of new mobile broadband services such as mobile TV, live video sharing and high resolution 3D gaming.

•The BCM96519 delivers more network capacity at a better cost than legacy T1/E1 and G.SHDSL systems in transport and access networks, allowing service providers to offer new services to both businesses and consumers wherever they are. Fixed (wired) network service providers can now deploy higher speed telecommunications services to business accounts and remote DSLAM cabinets using existing copper plants.

•The BCM96519 multi-line DSL terminal solution:

o Complements system vendors’ product portfolios by offering a high data rate, low complexity and scalable copper-based transport solution to feed IP service routers and remote DSL access concentrators. This enables carriers and service providers to re-use their existing copper infrastructure to reach remote and less dense subscriber clusters.

o Easily connects to Broadcom’s widely deployed BladeRunner™ family of high performance DSL central office and Fiber-to-the-Node, Fiber-to-the-Curb or Fiber-to-the-Building chipsets. This creates new revenue opportunities for telecommunications service providers, enabling them to add higher bandwidth services to wireless and wired networks in growing consumer and small-to-medium-sized business (SMB) applications.

o Provides better spectral compatibility with co-located ADSL and VDSL2 loops when compared to legacy E1/T1 or G.SHDSL technologies, and in turn, provides better overall connectivity rates and capacity for a given cable binder.

o Is integrated and standards-based, providing a small footprint design that reduces bill-of-materials (BOM) cost and eliminates the need for legacy or proprietary technologies.

o Is based upon the Broadcom® BCM6519 octal digital transceiver and the Broadcom BCM6529 dual analog front end companion chip with the following capabilities:

• For basic service provider requirements, the BCM96519 supports ITU-T standard compliant 992.3 ADSL2, 992.5 ADSL2+ and 993.2 VDSL2 protocols with additional support for 998.1 ATM bonding and 998.2 PTM bonding, up to 8 lines.

• To increase capacity, the BCM96519 supports ITU-T G.998.4 compliant physical layer retransmission and G.993.5 vectored VDSL.

• For carrier grade voice transmission and other timing sensitive applications to share the same backhaul links together with mobile broadband data and video transmission, the BCM96519 supports a high precision and innovative network timing recovery subsystem.

Greg Fischer, Vice President & General Manager of Broadcom’s Broadband Carrier Access line of business said:

“The production release of such innovative technology is another milestone Broadcom has achieved toward the IP-based convergence of wireless radio access networks and fixed broadband access networks where carriers and service providers can leverage both their existing copper infrastructure and installed access concentrators to reliably enable higher speed wireless and wireline services with minimal capital expenditures.”
