Telephone faults Self Checks

This page may be able to tell you if a fault exists on your own wiring or equipment.

If you have reported a fault your service provider should tell you to do this first test:

Your service providers line testing equipment is very sophisticated and rarely wrong, if you have been told that there is a fault in the property or a ca (customer apparatus) fault then it is very likely there is a fault.

Phone Line Checks..... this will help you do some initial checks

This is the type of phone socket supplied by service providers and is named the NTE (network termination equipment) which should be the first socket in the premises, this is what decides who owns the wiring and who is responsible for repairs.

The socket consists of two parts
The main socket (owned by the service provider)
which is the part secured to the wall (in blue) and the

Front Plate (your part of the phone socket)
which is secured to the main socket with 2 front pate screws

   

The test socket
Remove the front plate by removing the 2 front plate screws and you will see the test socket shown left

Insert a phone in to the test socket. If you have clear dial tone here then your internal wiring is at fault.

If you still have no dial tone or it is still faulty then it is possibly ** the responsibility of the service provider to repair

Please also be vigilant
If any part of the main socket is damaged and or damp, corroded or tampered with charges may apply.

You may not have the socket above fitted, it may look like the below picture.
If so then you will not be able to test your line without removing the extension wiring from behind if any attached

** This test is not a 100% guarantee that you will not be charged, some other factors may be involved for example:

Someone has wired extensions at or before the test socket

External/internal damage to the wiring that feeds the first socket,
service providers call this damage or 3rd party damage.

The test socket is not the first socket in the property, and there are other sockets and wiring before this.


If in any doubt call us
