BT iPlate - BT Broadband Accelerator (I Plate)

Dead easy to fit and comes with two long screws (see photo).

Below is a description of the i-plate from broadbandbuyer:

"What is the BT Broadband Accelerator & how does it work?
The BT Broadband Accelerator is a filter for use on ADSL Broadband lines to improve the speed & stability of the connection. Since they're easy to install yourself, (see YouTube video below) there are no costly engineer visits required. When connected to the master socket, the BT Broadband Accelerator filters the 'bell wire' which used to be needed to make our old-fashioned analogue telephones ring. However, with today's touch-tone phones, this bell wire is now redundant and its presence in a master socket actually causes digital interference on the ADSL line.

Please note that with a BT Broadband Accelerator, you will still need to use micro filters.

Increased speeds:
Some lines have seen up to 4Mb increases in speed although improvements of 1.5Mb were found to be more typical in a benchmark survey of 36,000 filtered lines. This indicates a potential 10Db extension in reach meaning BT Broadband Accelerator can also help with poor performing ‘Long lines’. These benefits were realized on ADSL lines and they'll be at least as good, if not better, on ADSL2+ lines.

Improved stability:

Since the BT Broadband Accelerator also helps to make ADSL connections more stable, there can be Broadband performance benefits even when line speed is not noticeably increased. The same benchmark study of 36,000 lines showed that filtered lines typically had 20% fewer re-trains (denoting lost connections) and a 45% reduction in error rate.

Who can use the BT Broadband Accelerator?
7 out of 10 UK homes will benefit to some extent – that’s approximately 9m Broadband lines. You must have a BT NTE5 type Master Socket (does your socket look like the picture below?).

Will I benefit from an BT Broadband Accelerator?
A good way to tell if your line is likely to benefit from bell wire filtering is to compare Broadband performance test results when the modem is plugged into the master socket, versus plugging it into an extension socket. If you see an improvement in broadband performance when the master socket is used, this is a good indication that an BT Broadband Accelerator will help."
