Edinburgh, Scotland-headquartered Spider Systems Ltd is launching a new family of multiprotocol tariff management routers under the generic name SpiderIntegrator. SpiderIntegrator will switch dynamically between different wide area network services such as ISDN and X25 at different times of the day to obtain lowest cost networking. According to Spider, SpiderIntegrator will support ISDN services across Europe, including the recently launched Euro-ISDN standard, and give access to X25 services such as Global Network Service in the UK, Transpac in France and Datex-P in Germany, as well as private X25 networks, and leased lines such as Kilostream-N in the UK and Transfix in France. The family supports IP, IPX and OSI protocols, but new ones can be added with a software upgrade without affecting existing configurations; its plug-in interface boards will similarly support new technologies such as 100Mbps Ethernet and Asynchronous Transfer Mode when they are more widely available, says Spider. The range will initially consist of the Pico, offering up to three wide area network interfaces, and the Mezza, offering up to nine wide area interfaces. The Pico Bridge Router chassis with IP and Fixed Ethernet will be UKP2,130, with plug-in boards from UKP290 and additional protocols from UKP300; the Mezza Bridge Router chassis with IP and Fixed Ethernet will list for UKP2,990, with plug-in boards starting at UKP590, and additional protocols from UKP300.
