    Fault testing with a master socket

    • Answer
    • Checking your line using a master socket

      Master Socket

      • Unplug anything connected to the sockets within your house before testing to make sure nothing is interfering with the master socket. This includes house alarms, telephones, faxes, computers, satellite TV digital boxes, adaptors and double adaptors.
      • Test your master socket with a corded phone which you know works properly.
      • If the corded phone works when plugged into the master socket then it's likely the cause of the fault is a piece of equipment or your internal wiring and the BT Network is okay.

      If you find there's a fault with a piece of equipment or your internal wiring:

      • To try to find the fault, plug each of your devices in, one at a time, and check the line again sfter each piece of equipment is added.
      • If you find plugging in one particular piece of equipment causes the problem to reoccur, unplug it and consult the user manual it was supplied with or contact the manufacturer.
      • If each piece of equipment works correctly try plugging a corded phone into each extension.
      • If you find a faulty extension you can contact BT on 0800 800150 or a local electrician to fix this problem. You will be charged for this repair.

      If you find the corded phone does not work when plugged into the master socket:

      • Double check the problem is probably with your line by plugging another corded phone into the test socket.
      • If you're still having problems you can report your fault online at www.bt.com/faults
