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.
