Broadcom's BCM1115 designed cost-sensitive, single Ethernet port consumer Enterprise Phone Gateway products. modules integrated BCM1115 include: MIPS32 150-MHz processor with two-way associative I-cache two-way associated D-cache. This supports VoIP protocol stacks, VxWorks operating system, customer application software. Programming done Broadcom's object-oriented signal processing API. 87-MHz with 48-KB instruction 32-KB data RAM. support narrow-band voice communication using G.711, G.726, G.723.1/A, G.729A/AB, BroadVoice®16, wideband communications using G.722 BroadVoice®32. Full-duplex speakerphone capability supported conjunction with these voice compression techniques phone designs. also supports enhanced packet loss concealment, jitter buffer, relay telephony algorithms e.g., DTMF call progress tones.
Analog codecs: integrated analog CODECs capable supporting both narrowband Kilohertz (KHz) wideband sampling, which, conjunction with wideband voice coders, such Broadcom's BroadVoice32TM, will enable phone networks deliver high-fidelity voice transmission. 10/100BASE-T media access controller transceiver. media access controller (MAC) supports 802.1p prioritization voice packets 802.1Q VLAN support segmenting physical networks into multiple logical networks. transceiver performs functions 100BASE-T Ethernet full- half-duplex mode over Category (CAT) twisted-pair cabling 10BASE-T Ethernet full- half-duplex mode over twisted-pair cable. also supports auto-MDI/MDIX detection allow cable type. transceiver integrates support in-line powering over Ethernet.
