⢠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
