Broadcom BCM1103 VoIP解决方案

Broadcom公司的Avaya 9600系列最先进的VoIP处理器BCM1103集成了MIPS和DSP处理器,吉比特以太网交换和快速以太网物理层器件(PHY).它所提供的特性使得BCM1103非常适合企业VoIP的应用,包括高保真音频,端到端安全保密以及先进的QoS.本文介绍了BCM1103的主要性特点和功能方框图.

　　Broadcom® VoIP Solutions for Enterprise and Small Business IP phones
Industrys Most Popular Gigabit Solutions for Enterprise Phones  
The Avaya 9600 series one-X Deskphone Edition phones are built upon Broadcoms most advanced VoIP processor, the BCM1103. In addition to the unparalleled performance provided by the integrated MIPS® and digital signal processing (DSP) processors, Gigabit Ethernet switch and Fast Ethernet physical layer devices (PHYs), the BCM1103 enables the delivery of features that are critical for enterprise deployments, including high-fidelity audio, end-to-end security and advanced quality of service (QoS).  

　　Several of Avayas enterprise IP phones also include Broadcoms BCM5482 single-chip Gigabit Ethernet transceiver, which maximizes the functionality of the BCM1103 VoIP processor for phones used on Gigabit Ethernet networks. The dual-port BCM5482 transceiver reduces bill-of-material (BOM) costs and utilizes less board space than competing solutions that use two single-port transceivers. This enables Broadcoms customers to build smaller and more cost effective IP phones.  

　　High-Quality Solutions for Cost-Conscious Businesses  
Avaya has also selected Broadcom VoIP solutions for its Avaya one-X Deskphone Value Edition (1600 series), which is a low cost family of phones designed to meet a range of end-user needs. The high-end model features Broadcoms BCM1104 VoIP processor, which enables advanced IP telephony features at price points that are attractive to cost-conscious customers. The innovative BCM1104 processor also integrates a Gigabit Ethernet switch and fast Ethernet PHYs, and runs all control and signal processing tasks on the MIPS processor core rather than employing a costly embedded digital signal processor.  
Included in the 1600 series lineup are two additional phones that include Broadcoms BCM1190 IP phone chip. By delivering cost effective IP phones with the same voice quality and security features as higher-end models, Avaya is providing small-and-medium-sized businesses (SMBs) with greater choices for deploying IP telephony across the board.  

　　The Broadcom BCM1103 IP phone chip enables manufacturers to build IP phones with integrated gigabit Ethernet switching, improved voice quality, hardware security, and advanced graphics-driven applications.
The chip integrates a gigabit Ethernet (10/100/1000 Mbps) switch and two fast Ethernet (10/100 Mbps) transceivers, allowing for the development of traditional fast Ethernet IP phone designs without the additional cost of adding external transceivers. With the addition of external gigabit Ethernet transceivers, manufacturers can easily upgrade their designs to create gigabit Ethernet IP phone models.
The BCM1103 integrates Broadcoms BroadSAFE security technology, which performs voice encryption and authentication and elevates the phones system security using a unique identifier embedded in each chip that is virtually impossible to decode, hack, or steal. This provides assurance that the identity of each phone in the network is genuine.

　　The chips high-performance RISC processor and DSP supports Broadcoms field-proven PhonexChange IP telephony software suite. PhonexChange includes a wide variety of narrowband and wideband voice coders, including Broadcoms high-fidelity BroadVoice® codec, a high-quality full-duplex speakerphone algorithm, advanced jitter buffer management and packet loss concealment techniques, and a complete library of standard telephony algorithms required for IP phone designs.

　　The RISC processor further allows customers to add productdifferentiating application software.

　　The chip integrates a variety of IP phone peripherals including wideband-capable analog codecs (coder/decoder) with integrated amplifiers, IrDA, USB host, and a touch screen digitizer. It also provides flexible interfaces for external peripherals and memory types. This high level of integration reduces the phones bill of material (BOM) costs and enables phone vendors to build scalable IP phone solutions using a single architecture.
