BT has announced the start of trials across the UK to gauge demand for its 330Mbit/s service.
The firm's Openreach division is hoping internet service providers (ISPs) will be able to find customers keen on receiving the service, with businesses cited as a key market segment the service could benefit.
The "On-Demand" trials will be hosted in High Wycombe, Bristol South, St Agnes in Cornwall, with Edinburgh's Waverley exchange will be added to the pilot in September 2012, and will also offer upload speeds of 30Mbit/s.
In the first phase of the trial ISPs will be able to place orders for the service where an interest is shown by their customers. They will then help cover some of the cost of the deployments carried out by Openreach.
Once completed, the firm will then begin the necessary rollouts and add four new areas to the pilots in Watford, Cardiff, Basingstoke and Manchester Central.
This pilot work should help Openreach assess the costs and requirements of providing Fibre to the Premise (FTTP) on-demand in the future.
Mike Galvin, Openreach's managing director of network investment, said the on-demand system could prove of great interest to businesses wanting to guarantee high-speed internet access for their staff.
"While we believe FTTC [Fibre to the Cabinet] will be our mass market consumer product for some time yet, FTTP may be of interest to small and medium sized businesses and so we want to make it accessible throughout our fibre footprint," he said.
"This development can potentially help SMBs to compete both at home and abroad as well as maintain and create jobs across the UK."
On Tuesday BT announced 98 new locations that will be upgraded with FTTP and FTTC services as it looks to provide two-thirds of the UK with high-speed broadband services by 2014.
