The Broadcom BCM3352 represents a new and unprecedented
level of integration for PacketCable Multimedia Terminal
Adapters (MTA.) The BCM3352 provides a unique solution for
low power and cost effective MTAs that can deliver primary line
VoIP cable telephony and broadband data services over phone
lines worldwide.
Key modules integrated in the BCM3352 include:
• Enhanced VoIP DOCSIS/EuroDOCSIS 1.0/1.1 based MAC
integrating 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.
• 200+ MIPS VoIP/FoIP DSP with patented PacketSync™
delivering four channels of compressed voice packets,
including G.711, G.726, G.729a/b/e, and G.728 Vocoders,
plus T.38 Fax Relay.
• Integrated iLine32™ HPNA 2.0 home phone line interface
that eliminates hundreds of dollars worth of additional
telephone and Ethernet wiring.
• High-performance 120 MIPS, 100-MHz MIPS32 processor
with a 4K two-way set associative I-cache and a 4K two-way
associative D-cache.
• Broadcom Propane™ software support for enhanced
bandwidth efficiency and turbo modem performance.
• Integrated 10/100 Ethernet MAC for support of small
business integrated access device applications.
• IPSec module with single-DES (CBC & ECB modes), triple-
DES (CBC & ECB modes), MD-5 and SHA authentication
in hardware, providing support for Virtual Private Networks
(VPNs).
• Integrated four-channel FlexiVoice™ Voice Codec with
individual line programmable filter coefficients, providing
optimum performance for both V.90 modem and voice
applications.
