ISP Spitfire has confirmed its participation in BT Wholesale's first consumer trials of Very High Speed Digital Subscriber Line 2 (VDSL2) technology.

The VDSL test will initially facilitate the provision of downstream speeds of between 15Mb and 40Mb and upstream speeds of up to 2Mb, although an upstream speed increase to 5Mb is expected.

Taking place in Muswell Hill, London and Whitchurch, Cardiff, the trial will commence on July 1st and run until December.

"We are delighted to have been selected by BT Wholesale for this important trial," commented Spitfire Sales Director Tom Fellowes.

"SIP trunks and hosted SIP telephony are now moving into the mainstream and VDSL will give an important boost to the take-up of these critical new comms technologies."

Nine other UK ISPs have already been selected by BT Wholesale to take part in the assessment programme, including PlusNet and Entanet.

The move is a precursor to 28 more exchanges being enabled with VDSL2 technology early in 2009.
