How to test Openreach NTE socket 
Follow the instructions to check your BT Openreach socket and phone line (for help call 01226 337070)
When you have a problem the first things your Network provider will ask are:
  • Try Using the Test point
  • Have you changed the Filter
  • Do you have a Dial Tone
  • Is there any Noise on the line
Most New BT Sockets are very Similar
generally the front part of the socket can be removed either by two small screws or on the latest NTE5C sockets it can be removed without tools

The test socket is larger than normal, but it will still allow a std BT telephone to plug in at the top edge of the test socket
Line Test
  • Plug a Standard Analogue phone into the test socket - you should get a Dial Tone
  • To check the Telephone Number Dial 17070 - you will hear a message giving you the telephone number associated with the line
  • Quiet Line Test - This lets you hear if there is Noise or crackling on the line
The Filter 
is a small white box that has a BT style plug that the you plug into the wall socket 
and on the other end the box has two sockets 
One for a Telephone and the other for a Router (for your Broadband)
This prevents Voice calls and Data interfering with each other
