BCM1100 VoIP Ethernet CPE Engine The Broadcom BCM1100 represents a new level of integration for enterprise Ethernet IP Phone and small gateway applications. Key modules integrated in the BCM1100 include:
· MIPS32 100 MHz processor with 4K 2-way set · 10 / 100BASE-T Ethernet Switch, Media Access
· ZSP 140 MHz DSP with 48K instruction and 32K data
RAM. The DSP supports a wide range of vocoders, acoustic echo cancellation for full-duplex speakerphone, fax modems, and a variety of telephony algorithms (e.g., DTMF and Call Progress Tones).
· Analog Codecs. Three ADCs and DACs are integrated,
Controllers, and Transceivers. The three-port Ethernet switch integrates three full-duplex capable Media Access Controllers (MACs), a Serial Management Port, an address resolution engine, a non-blocking switch controller, 64K of internal switch memory, 802.1p prioritization for voice packets, and a set of Management Information Base (MIB) statistics registers. The two transceivers perform all of the functions for 100Base-T Ethernet in full- or half-duplex mode over Category (CAT) 5 twisted pair cable and 10BASE-T Ethernet in full- or half-duplex mode over CAT 3, 4, or 5 twisted pair cable. They support Auto MDI / MDIX detection to allow the use of any cable type in either port. The BCM1100 represents the first silicon solution that integrates all the key silicon components of an Ethernet IP Phone into a single device, thereby reducing the overall system cost and complexity of Enterprise IP Phone products, while at the same time increasing their voice quality and the reliability of the network to which they are attached.
eliminating the need for an analog switch to allow the sharing of a codec between multiple interfaces.
