Business ISP Spitfire has today announced the launch of its new DualStream SDSL broadband (symmetric - same speed both ways) service. The new product provides customers with two separate DSL circuits routing via different paths to the Internet and costs from upwards of £85 per month for a 2Mbps connection.

The primary circuit is provided by Spitfire’s LLUStream (unbundled) SDSL and the back up circuit is supplied by Spitfire’s IPStream ADSL. Spitfire can supply the same IP addresses to both the primary and the back-up circuits so that in the event of the Primary circuits failure the back-up IPStream ADSL circuit can connect to the same IP range in about 90 seconds. This means that an office and even remote workers are able to reconnect to the Internet within minutes of Primary circuit failure:


DualStream SDSL has been designed as a low cost Internet back-up service with a one-time connection charge of £250. An entry level service costing £85 a month for a Primary 2Mb LLUStream SDSL circuit with 20:1 contention and 2Mb IPStream ADSL 20:1 contention back-up circuit. Spitfire can also supply DualStream SDSL with lower contention ratios for the primary LLUStream SDSL circuit including 1:1.
