BCM1100 VoIP Ethernet Engine Broadcom BCM1100 represents level integration enterprise Ethernet Phone small gateway applications. modules integrated BCM1100 include:
MIPS32 processor with 2-way 10/100BASE-T Ethernet Switch, Media Access
associative I-cache 2-way associative D-cache. This supports VoIP protocol stacks, jitter buffer management, application program. Programming done Broadcom's objectoriented signal processing API.
with instruction 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,
Controllers, Transceivers. three-port Ethernet switch integrates three full-duplex capable Media Access Controllers (MACs), Serial Management Port, address resolution engine, non-blocking switch controller, internal switch memory, 802.1p prioritization voice packets, 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. BCM1100 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.
eliminating need analog switch allow sharing codec between multiple interfaces.
