PRODUCT
Brief
BCM1100
•
10/100BASE-T Ethernet Switch with 802.1p Support
• Ensures QoS for voice packets and minimizes latency
• MIPS32 CPU not burdened by data packet processing,
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
BCM1100 VOICE OVER IP ETHERNET CPE ENGINE
