Are Telephone Engineer required when diagnosing a line fault?
Telephone Engineer Clock Face need you to know when the telephone line goes dead many people panics and call their service provider straight away but this could turn out to be an expensive mistake. Some faults can be caused by equipment and extensions within the home that are not covered by the service provider.
Most houses in Clock Face use a master socket known as an NTE5 which has a detachable front plate that can be removed by taking out 2 short screws. By removing this front plate, assuming the house has been wired to standard, you will be disconnecting all internal telephone extensions. The remaining part of the master socket or NTE5 now has a test socket in the bottom right-hand corner to be used to test the incoming line.
Are You Getting A Dialing Tone?
The next step is to take a telephone that you know is working, preferably one that does not require mains electricity, and plug it into the test socket and listen for a dialing tone. If there is no dialing tone at this test socket then the fault is very likely to be in the external network and all work to repair the fault can be carried out by the service provider free of charge.
Your Clock Face Based Phone Line Engineer can test if there is a dialing tone at the test socket and the tone disappears when the front plate is reinstated then there is a fault on the internal wiring or equipment. The next step is to unplug from telephone sockets any equipment/modems/telephones in the house. If there is still no dialing tone then there must be a fault on the internal wiring within the house.
