BCM1101 VoIP Ethernet Engine
Broadcom BCM1101 represents level integration feature-enhanced Ethernet phone products. modules integrated BCM1101 include: MIPS32 150-MHz processor with two-way associative Icache two-way associative D-cache. This supports VoIP protocol stacks, jitter buffer management, application program. Programming done Broadcom's objectoriented signal processing API. 108-MHz with 48-KB instruction 32-KB data RAM. supports wide range vocoders, acoustic echo cancellation full-duplex speakerphone, modems, variety telephony algorithms (e.g., DTMF call progress tones). Analog codecs. Three ADCs DACs integrated, eliminating need analog switch allow sharing codec between multiple interfaces. 10/100BASE-T Ethernet switch, media access controllers, transceivers. three-port Ethernet switch integrates three fullduplex capable Media Access Controllers (MACs), serial management port, address resolution engine, non-blocking switch controller, internal switch memory, 802.1p prioritization voice packets, 802.1Q VLAN support segmenting physical networks into multiple logical networks, Management Information Base (MIB) statistics registers. transceivers perform functions 100BASE-T Ethernet full- half-duplex mode over Category (CAT) twisted pair cable 10BASE-T Ethernet full- half-duplex mode over twisted-pair cable. They support auto-MDI/MDIX detection allow cable type either port. transceivers also integrate support in-line powering over Ethernet. BCM1101 represents first silicon solution that integrates silicon components Ethernet Phone into single device, thereby reducing overall system cost complexity Enterprise phone products, while same time increasing their voice quality reliability network which they attached.
