Broadcom releases new chipset for ethernet-based wireless, wired backhauling applications

Uses multi-mode ADSL2+/VDSL2, vectoring and channel bonding technologies

By CBR Staff Writer

Broadcom has released a new chipset, 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, a multi-line digital subscriber line (DSL) terminal offering, leverages the company’s multi-mode ADSL2+/VDSL2, vectoring and channel bonding technologies.

The company claims that the BCM96519 increases the capacity of ethernet connectivity over copper, almost 10-fold, with rates approaching 1 gigabit per second (Gbps) speed.

According to Broadcom, the new BCM96519 multi-line DSL terminal provides wireless service providers with upgrades to multi-megabit per second (Mbps) backhauling links supporting 3G and 4G base stations, or Node Bs. It connects to the company’s BladeRunner family of DSL central office and fibre-to-the-node, fibre-to-the-curb or fibre-to-the-building chipsets.

The company said that the new offering provides better spectral compatibility with co-located ADSL and VDSL2 loops 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.

Greg Fischer, vice president and general manager of broadband carrier access line of business at Broadcom, 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.
