A faulty telephone line can cause huge problems and it can sometimes be difficult to address the issue as quickly as you would like.
The major service providers quote repair times as up to 3 working days however the weekend doesn't count so in reality it could be 5 days before they send an engineer to repair any telephone faults.
There is always a potential charge should an engineer decide that the fault is with your own wiring or a multitude of other reasons such as the line is ok when the engineer visits, damage caused on your property, all of which could range from £65.00 to £129.99 and sometimes more for a residential fault (Dependent on service provider) and currently £245.00 + VAT if it is a business fault.

Cotswold Connection offer a same day response (Workload permitting) to diagnose any telephone faults and repair them should the fault be with customers wiring or within the boundary of the property or prove conclusively that the fault is indeed a network issue. If the fault is proved to the network then the issue will be escalated to your service provider and an engineer appointment booked for them to carry out any repairs on their network

The Master Socket:


The NTE5 or more commonly known as the master socket is the demarcation point between customer owned wiring and the telephone network. The latest NTE5 should look similar to this.


The master socket has a detachable frontplate with a test socket behind it. This is the demarcation point and your service provider will always ask if you have carried out your own tests from the test socket. If there is dialtone at the test socket then whatever is causing the fault is with the internal wiring or equipment connected to it. If there is no dialtone in the test socket then it's always best to try another phone just in case the phone is faulty. If there still isn't any dialtone then the fault is likely to be on the network cable coming into your property and will have to be reported to your service provider. They should run a line test and confirm that there is a fault and arrange for an engineer to visit. It isn't always possible to locate the master socket and it may be that there isn't a master socket in the property. Older style sockets LJU's do not have a detachable frontplate which in turn means that it isn't possible to disconnect any internal extension wiring to carry out a test.

Telephone fault categories

Telephone faults can be anywhere between the local telephone exchange and the customers property and generally fall into the following categories.

Exchange: Faults in the local telephone exchange are usually identified during a line test. Symptons can range from No Dialtone to noise on the line or being able to make calls but not receive them.

E Side: The E Side refers to the cables leaving the telephone exchange and going to the green street cabinets. Symptons range from No Dialtone to noise on the line. E Side faults tend to be less common as the cables are pressurised.

D Side: D Side is the cable network leaving the street cabinet and going to telegraph poles or underground distribution points close to the property.

Overhead: The cables between the telegraph pole and the customers property. Again the symptoms tend to be No Dialtone or noise.

Common telephone faults

Line tests normally give a good indication of what and possibly where the fault may lie. The worst possible result is that the line tests OK even though you know you have no dialtone or the noise is so bad that you can't have a conversation. Your service provider will always try to say that the line tests OK so therefore it must be your wiring or equipment that is faulty and threaten you with a large bill if they have to arrange for an engineer.
Dis in the network is a clear indication that there is a fault in the network, this will result in the loss of dialtone and you won't be able to make or receive calls. This fault will need to be repaired by engineers working on behalf of your service provider and should not be chargeable unless there is damage to the cable within the boundaries of your property caused by trees, building work or accidents by trades people.
Earth Contact tends to be an underground fault and is normally associated with a humming noise on the line.
Battery contact again tends to be an underground issue which will result in a noisy line or possibly no dialtone.
A Loop fault is essentially a short circuit on the wiring and can be anywhere between the telephone exchange and the customers equipment. Common causes of loop faults are faulty ADSL filters and occasionally set top boxes. A full loop will result in no dialtone, being unable to make outgoing calls and the line being engaged on incoming calls.
A rectified loop is a partial short circuit and can result in the phone ring once and cutting off. Rectified loops tend to be more on the customers property and are generally caused by damp.
