Not working for TT I cant say in detail what their proceedures are for fault reporting processes, however before a fault can be reported for investigation by Engineers certain questions from an industry standard script must be answered by the customer, in fact this script is available from BT Wholesale and not only that but eco-repair explicitly asks that these questions have been asked.
Carphone's target is May i think for 1000+ exchanges being unbundled I beleive. This is a target they have stated in public and I'm sure will be met.
I can't comment on TT and your interleaving issue as I don't know the details...perhaps talktalkboy can? Though I will say that I used to work for a VERY WELL REGARDED ISP that charges the earth for connections and was informed that they had taken the decision to stop supporting third party equipment; they had done it on the grounds of the time it was taken for support to assist users. This was an ISP that regarded itself on Customer Services.
