The faceplate should be fitted to the supplied 23mm standard single back box using the included fixing screws. The included IDC tool can be used for connecting the internal wires on the BT cable to the master socket. The NTE5A master socket has a removable front panel which makes testing a line extremely easy. This is the latest version of BT socket with a bellwire filter which can help to improve broadband speeds. The BT drop cable coming from outside the property usually has orange, white, green and black wires. Usually the orange and white internal wires are the active pair and go to connections A and B on the master socket, in some master sockets these connections are marked 2 & 5. If you are removing or changing your current master socket, you can check which wires are the active pair by looking at the original wiring. The polarity can sometimes stop some equipment from working. One of the cables will have a voltage of -48V and this needs to go to pin 5 (B) and the other will have a voltage of 0V and this needs to go to pin 2 (A). Voltage can be checked by using a multimeter. The BT drop cable has more than 1 pair of internal cables, this is for if you wish to have 2 or more lines in your property, or if a pair fails, the chances are that there are still existing pairs available, hence there would be no need to replace the drop. Made from high gloss VO rated material. Supplied with single back box, fixing screws and tie-wrap. Supplied with IDC Punch down tool. Can be flush or surface mounted. Official Loops Product!
