The choice of unbundled (LLU) providers has been extended due to ISP Tiscali planning to unbundle up to 200 exchanges by the end of the year.
They plan to install equipment from Chinese manufacturer Huawei , whose kit will also be used by BT, having won a major role in the construction of  21st Century Network, into up to 700 exchanges.

Tiscali said it will have unbundled 27 London exchanges by the end of this week, rising to 200 by the start of 2006, and then onward to 700 by the end of 2006. This will mean that nearly 40% of UK households will be able to connect to a Tiscali LLU exchange.
But it doesn't come cheap, such an investment will cost in the region of £60m, but Tiscali hopes to reclaim this by providing not only broadband services, but also telephony and TV in the near future.
