The provision of telecommunications services, including broadband, is a matter in the first instance for the fully liberalised private sector, regulated by ComReg, the independent Commission for Communications Regulation.
The question of enabling telephone exchanges for broadband is an operational matter for Eircom, and I have no function in the matter.
My Department's website www.broadband.gov.ie lists a number of broadband service providers offering services in all parts of County Donegal, using a variety of broadband technologies such as DSL, wireless, fibre, cable and satellite. The website gives prices for the various services on offer, and contact details for each of the companies.
