new products Fanless wall mount computer The PicoBox is one of the compact wall mount high performance, fanless industrial computers with comprehensive and multi-functional features in the Boxline range from BEG Bürkle. The unit measures 88mm high x 230 mm wide x 300 mm deep. It has a Core Duo T2500-processor and a CPU cooling system with thermosiphons. The basic evaporation and condensation principle of thermosiphon allows for a considerably higher transfer of heat energy, as compared to conventional heat pipes. It uses a Seagate 2.5-inch EE25 hard disk which permits continuous 24-hour operation within the ambient temperature up to 50°C. For a more robust system, data storage can be provided by an IDE ﬂash disk module with up to 8 Gbyte of storage and whcih has no moving parts. The arrangement of all the operating agents, connections and drives on one side is user friendly. This also allows for different mounting options which are simply convertible by means of L- and Z-brackets. Since the chassis carries the cooling system on the rear, the PicoBox can be universally installed. The compact dimensions and fanless construction are suitable requirements for a decentralized integration into industrial equipment. The PicoBox is resistant to all kinds of vibrations, aggressive emissions and ﬁne dust particles. www.beg-buerkle.de VME switch for L3 Gigabit Ethernet The ComEth4070a family from Interface Concept is a line of 6U VME L3 fully managed Gigabit Ethernet switches for embedded applications. It uses the latest generation Gigabit switch engine and PHY transceiver and combines a layer 2+ switch and a full layer 3 router in a single board with optimized power consumption. The board supports full-wire speed L2 bridging and IP routing with L2-L4 Access List for classiﬁcation, ﬁltering and prioritization. The ComEth4070a provides 24 Gigabit Ethernet ports with a full-wire speed switching capacity of 37 Mpps. Twenty Gigabit Ethernet ports are routed on the P0 & P2 rear connectors; the four remaining Gigabit Ethernet channels are available on the front or via the P2. The front option can provide four 1000BT (RJ45) ports or optionally 1000SX/LX ﬁbre channels. The switches are fully managed and can be monitored from a browser, a remote application, a CLI or SNMP. www.interfaceconcept.com Vocoder chip eases multi-rate voice compression Digital Voice Systems has introduced the AMBE-3000 vocoder chip, a DSP based voice compression solution that is suitable for full or half-duplex, real and non-real time, communication systems. The chip implements DVSI’s patented AMBE+2 voice compression algorithm which is used for many mobile radio programs including DMR in Europe and APCO Project 25 in North America. It is also used by satellite systems to provide superior voice quality at low bit rates. The chip can operate at virtually any data rate from 2.0 to 9.6 kbits/s. This allows the user to optimize speech and/or FEC rates within their system 42 requirements to provide excellent voice quality with superior robustness to bit errors and acoustic background noise. The AMBE-3000 provides full or half-duplex operation, automatic voice/silence detection (VAD), adaptive comfort noise insertion (CNI), DTMF and call progress tone detection/regeneration, echo cancellation, low power modes and frame-by-frame “on-the-ﬂy” rate switching. As the latest addition to DVSI’s family of voice compression products, the AMBE-3000 has interoperable modes that provide a seamless migration path from systems already using DVSI’s AMBE-2000 and AMBE-1000 vocoder chips. These features, combined with the chip’s low power consumption and small form factor (128 pin LQFP of BGA package), make the AMBE-3000 suitable for wireless applications where bandwidth is at a premium and lowdata-rate, high-voice-quality is imperative. The AMBE-3000 Vocoder chip is designed for easy integration, with set-up, control and operation through control pins or a packet interface. It provides the choice of a UART, a parallel port or a serial port for vocoder conﬁguration, status information, as well as, transferring speech and compressed data bits to/from the chip’s encoder and decoder. www.dvsinc.com JANUARY – FEBRUARY 2007 | embedded systems design europe | www.embedded.com/europe 042_ESDE.indd 42 7/02/08 16:25:37 http://www.beg-buerkle.de http://www.interfaceconcept.com http://www.dvsinc.com http://www.embedded.com/europe
