From its offshore Sunnyvale, California base, the Cambridge, UK-based Advanced Telecommunications Modules Ltd has announced Streamlink, which it describes as the industry’s first Ethernet-Asynchronous Transfer Mode adapter boards for the desktop – and the Streamswitch 7000 series of Asynchronous Transfer Mode campus switches. The boards are designed to enable migration from Ethernet to ATM. The entry-level version, the Streamlink 2010, supports either 10Mbps Ethernet or 25Mbps ATM with 25Mbps ATM full-duplex performance. The 2020 network interface board supports either 10Mbps Ethernet or 155Mbps ATM. Both include an embedded ARM RISC processor for lower CPU utilization and are software- programmable. They support ATMoS, the company’s rea l-time operating system for multimedia streams. The ATM and IP/ATM standards are also supported, along with feature support for ABR, UBR and Early Packet Discard, and the boards operate under Windows95, Windows NT, NetWare, Forum Lane and IP/ATM env ironments. Advanced Telecommunications Modules’s multiprotocol Streamswitch family of stackable 155Mbps ATM switches is claimed to be fully scalable and provides an IP switching option which supports the Generic Switch Management Protocol. The base unit, the Streamswitch 7000, is a three-slot modular switch for workgroup or server clusters and can support six to 12 ports, with 1Gbps switching power. The 7200 and 7400 each have six ports supporting 155Mbps unshielded twisted pair and 155Mbps mu lti-mode fiber respectively. The 7600 has six 155Mbps ports and supports single-mode fiber. The 2010 and 2020 adapter boards will be available by the end of the year for $200 and $500 respectively. The Streamswitch 7000 is $4,000, the 7200 is $12,00 0, the 7400 is $10,000, and the 7600 is $29,000.
