Broadcom's new VoIP digital signal processor for next generation MSANs

Broadcom Corporation introduced its new voice over IP (VoIP) digital signal processor (DSP) BCM6515, that targets next generation OEM designs of multi-service access nodes (MSANs), IP digital subscriber line access multiplexers (IPDSLAMs) and deep fiber multi- dwelling units (MDU).
The new device offers low cost and high quality telephone services that can be bundled with high-speed Internet access, IPTV and a host of converged wireless capabilities.

The features are listed below:

1. Provides a ready-to-use voice access solution
2. Provides up to 72 lines of complex voice coding.
3. Provides high-speed voice coding, voice compression, IP processing and embedded adaptive jitter buffering with direct uplink network connectivity in combination with Broadcom's BCM5481 Gigabit Ethernet transceiver.
4. Supports ITU standard codecs such as G.711a and u, G.726, G.729a, G.723.1, TR38 fax relay, three way conferencing and many more narrow band telephony.


Broadcom also announced the availability of its BCM96515, voice line termination reference design, which is a joint collaboration between Broadcom and Zarlink Semiconductor Inc. The BCM96515 reference design is based on Broadcom's BCM6515 DSP and BCM5481 Gigabit Ethernet transceiver chip, and Zarlink's VoiceEdge VE792 next generation carrier chipset. The VE792 chipset includes an octal subscriber line audio-processing circuit with an integrated carrier-grade line test toolbox, single channel subscriber line interface circuits, and a multi-port voice control processor that provides real-time call control functions, as well as carrier-grade line testing.

Availability: The BCM6515 VoIP DSP is now sampling to early access customers.
