"Configured to a maximum of .....". Surely this configuration (Capping ?) needs removing now the attenuation issue has been resolved. It was that which was the absolute major contributing factor, to only having a max possible connection of 22/23 Meg. The attenuation is back to what it should be, and therefore the DSL should be reset to default inorder that BE gets his full whack back.
Walter, we don't fault to component level anymore, haven't done for over 20years. If the socket is faulty, the whole thing will be changed out.
We will only change the RJ11 lead if a 'Boost' task has been raised against the fault. The 'Boost' tasks are currently dominated by BTr, but I believe Plusenet and Sky are either coming on board, or are on board but I haven't had a task from them yet ?? With the 'Boost' tasks, we are allowed to replace the Hub/Router and associated leads. With bog-standard SFI tasks, we only work to the socket.
BE -- your question wasn't "Silly" as this method was employed over the years on POTS lines over a certain distance.
