BT NTE5 Compatible ADSL Broadband Faceplate Splitter Adaptor Socket This splitter ADSL faceplate is of the type installed by BT engineers for ADSL service to your home. Shown to increase broadband speed and reliability in many cases, this ADSL faceplate replaces the lower half of your BT NTE5a or NTE5b master socket, and provides outlets for RJ11 (for ADSL modems) and 431A (for telephone line equipment). This phone socket with built-in ADSL filter gives you the advantage of needing only one filter, instead of filtering each socket in your home for ADSL connection, and is ideal for connection to a single computer in close range to the master socket. Note: The NTE5 master socket is the type that when the lower half is un-plugged, it isolates the BT network side from the subscriber. Any ADSL modems connected to the filtered output, either via the socket on the front or connected into hardwired extension sockets wired from the rear, will not function from these filtered outputs. S
