Broadcom Announces Multi-Line DSL for Ethernet-based Backhauling

Broadcom announced a new chipset for Ethernet-based wireless and wired backhauling applications, as well as Ethernet-based business applications.


The new Broadcom BCM96519 is a multi-line DSL terminal solution that implements multi-mode ADSL2+/VDSL2, vectoring and channel bonding technologies. Broadcom claims the device could be to significantly increase the capacity of Ethernet connectivity over copper, almost 10-fold, with rates approaching 1 Gbps speed.


Broadcom said its BCM96519 delivers more network capacity at a better cost than legacy T1/E1 and G.SHDSL systems in transport and access networks. It also 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.


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.


The new chipset connects to the company's widely deployed BladeRunnerfamily of DSL central office and Fiber-to-the-Node, Fiber-to-the-Curb or Fiber-to-the-Building chipsets. Broadcom is also announcing a production-ready reference design platform and associated firmware for the new chipset.
