• Enhanced VoIP DOCSIS/EuroDOCSIS 1.0/1.1 based MAC
• 200+ MIPS VoIP/FoIP DSP with patented PacketSync™
• Integrated iLine32™ HPNA 2.0 home phone line interface
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.
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.
that eliminates hundreds of dollars worth of additional
telephone and Ethernet wiring.
