The Broadcom BCM3351 represents a new and unprecedented
level of integration for PacketCable Multimedia Terminal
Adapters (MTAs). The BCM3351 provides a unique solution for
low-power and cost-effective MTAs that can deliver primary line
or secondary line VoIP cable telephony and broadband date
services to the home worldwide.
Key modules integrated in the BCM3351 include:
• Enhanced VoIP DOCSIS/EuroDOCSIS 1.0/1.1 based MAC
integrates a wirespeed DES encryption/decryption engine, full
DOCSIS/EuroDOCSIS 1.1 QoS, support for 16 SIDS in the
downstream, 256 multicast and Unicast DA CAM,
16 independent DMA controlled upstream queues, as well as
extended network management MIB and diagnostic features.
• 100+ MIP VoIP/FoIP DSP with patented PacketSync , supports
two primary lines of compressed voice packets including G.711,
G.729a/e and G.728 vocoders, plus T.38 fax relay.
Simultaneously it can support two secondary lines of G.711 for
class services such as three-way calling and caller ID.
TM
• Integrated two-line FlexiVoice™ Voice Codec with individual
line programmable filter coefficients, providing optimum
performance for both V.90 modem and voice applications.
• High-performance 160 MIPS, 140-MHz MIPS32 processor has
an 8K two-way set associative I-cache and a 4K two-way
associative D-cache.
• Broadcom PROPANE™ software supports enhanced bandwidth
efficiency and turbo modem performance.
• IPSec module with single-DES (CBC and ECB modes), tripleDES (CBC and ECB modes), MD-5 and SHA authentication in
hardware provides support for Virtual Private Networks (VPNs).
• Integrated iLine32™ HPNA 2.0 home phone line interface
eliminates hundreds of dollars worth of additional telephone and
Ethernet wiring.
• Integrated 10/100 Ethernet MAC supports small business
integrated access device applications.
