A bit more pricey than the passive ADSL filtering alternatives,
Sorry
Jason but I shall dispute your implied comment (by using the word
passive in the above) that the "Premium Centralised Filter" is an
active device. It is not.
It is a passive device based on the concept of nothing more than an interstitial filter.
It is, in fact, nothing more than the device shown as the "Broadband Accelerator" (and marketed by
BT / OR, a few years ago, as the
iPlate) with the filtering components of the "Standard Centralised Filter" added to it!
