leaving more cycles for application program
• Enables wire-speed non-blocking operation
• Blocks unnecessary traffic by learning local MAC
addresses
• Segments network, preventing any restriction on
number of hops
• ^{100 MHz MIPS32 CPU Supporting:}
• H.323, H.248/Megaco and SIP
• Application program
• ^{140 MHz DSP Supporting:}
• G.711, G.726, G.729A/AB/E, G.723.1/A, G.728
• Half- and full-duplex speakerphone operation
• Two- and three-channel conferencing
• Fax relay (T.38, V.17, V.29, V27ter)
• Ancillary telephony algorithms
• ^{10/100BASE-T Ethernet MACs and PHYs}
• Provides Auto MDI/MDIX enabling the use of straight
or crossover cables in either port
• ^{Wideband Audio CODECs}
• Enables support of emerging wideband vocoding
standards
• ^{Glueless Interface to BCM4210/4100 HPNA MAC and}
AFE Devices
• Enables low-cost home networking IP phone prototyping
