The line monitoring system allows you to track the performance of your broadband connection in terms of latency and packet loss.
If you do not use microfilters, and still want to use a phone then a replacement Master socket cover that filters the ADSL or VDSL2 signal from the extensions is needed.
Filtered faceplates are a lot easier to find today than a few years ago with numerous sellers now listing them on Amazon As there are various versions of faceplate and the curvy 5c version is not compatible with older master sockets (and vice versa) make sure you are buying the correct version.
These companies also offer a variety of extension sockets with built-in microfilters, thus avoiding the need for an unsightly cable tangle. Also locating the DSL modem at the master socket should be the optimal location to avoid losing connection speed, this is more important with VDSL2 (FTTC) than ADSL2+ and will be very critical when G.fast is widely available.
Almost all broadband orders for ADSL2+ and VDSL2 are self-install, some providers may allow you to add an additional engineer visit, but this usually doubles the set up cost.
As when ADSL2+ and VDSL2 was first rolled out we expect G.fast to come with an engineer visit for the first year or so as Openreach tries to make sure people get the best speeds.
Users applying for a 0.5Mbps or 1Mbps service on a very long line may still see a note about a possible engineer visit. This visit will only occur after the line has been activated and if you are having problems with the service. For example if your ADSL modem will not connect (sync) with the exchange hardware.
If an Openreach engineer does visit as part of a boost and you do not have a modern master socket they will usually install a new master socket, but be warned they do not usually re-wire all your extensions the extra time for that work is likely to be charged to you, so make sure you know what the cost is upfront.
Extension leads with RJ-11 plugs are available from a variety of sources, e.g. Comet, B&Q, Argos, Dixons etc.
Generally online sources are the cheapest. Some of the best cables will be made using CAT5e cable, but this is only necessary if you are having problems with existing wiring. High prices does not always equate to better, so check reviews for the item you are busying.
You only need a microfilter for your analogue telephones and anything else like a Sky box that is plugged into the phone line. If you do not have any telephones on your line, there is no need for a micro-filter. What you will need is an adaptor for the normal ADSL modem lead to convert the RJ11 plug to a standard BT plug - in the majority of cases your old 56K modem lead will suffice.
It will vary from location to location. Generally upto 30m of CAT5 cable is fine, longer is possible.
Normal phone extension cabling is fine for the vast majority of ADSL users so long as it is a twisted pair cable (standard name is CW1308), but for those with a low signal to noise ratio they may find using CAT5 twisted pair cabling improves the stability of the line. If installing extensions remember to avoid running them parallel to mains cable and other interference sources.
If you have your line activated and are having problems it is suggested that you unplug all extensions and try the ADSL modem at the test socket that is part of the main BT socket.
If you are going to put in a new extension, then a normal phone extension kit will be sufficient. There is no need to buy expensive extra high speed type cabling. Always ensure though that the extension is already filtered by a faceplate or you connect the phone via a micro-filter.
A micro-filter is a special adapter that you need to use on your phone line, so that your telephones do not interfere with your ADSL connection. Some people call them a 'splitter', the naming is interchangeable.
Engineer Assisted installations are optional (in most cases) and more expensive. An engineer will visit your premises to connect and configure a supplied modem or router, and answer any questions you may have. Businesses often prefer engineer assisted installations because internal extension cabling is frequently needed.
Self Install is sometimes described as 'wires-only'. During the activation phase, you'll never see an engineer (unless there is a specific problem with your telephone line). Shortly after placing an order with your chosen ISP, you'll be assigned an activation date, assuming your line passes the required tests (see our Technical FAQ). In the meanwhile, you'll need to purchase an ADSL modem or router (often available from your ISP). If purchasing a router, ensure that it also includes an "ADSL modem" in it, and isn't just a broadband router (see our reviews for some examples). After activation, you should be able to connect with the details supplied by your service provider.
The wording 'very unlikely' is used to denote those lines that BT Wholesale think are very long, and therefore the chance of it not working is much higher than on average.
It is still worth ordering as until the line is activated you cannot tell for certain whether the service will work. If the line fails to work BT Wholesale will not charge the ISP anything, and any contract is considered void by BT Wholesale. This means your ISP should refund you any money taken in advance if the line does not work at all.
If your immediate neighbours have a working service you can usually get an idea of whether the checker estimate is seriously wrong or on the ball by running a speed test to find out how fast they get. Though due to the vagueries of the phone network there are cases where areas have vary different line lengths and quality so the speed of a neighbour goes not guarantee you will get the same speed.
As most people are keen to have reliable video streaming, you need to order a service that will usually support download speeds of 5 Mbps or better. If there are several people in your home multiple the 5 Mbps by the number of people who will be streaming at the same time.
Superfast broadband services are very widely available now, but while the adverts talk of up to 38 Mbps and up to 76 Mbps not everyone will get those speeds, so when comparing providers prices make sure you check their speed estimates for your address. Also pay attention to the upload speeds, gamers who enjoy broadcasting a video stream while they play will need the up to 9 Mbps or faster upload services and not the bargain basement up to 1.9 Mbps providers sell as their entry level service.
VDSL2/FTTC is normally faster than ADSL2+ but this is not always the case, so if your speed predications are down in the sub 3 Mbps type area, you may find that ADSL2+ is more stable compared to VDSL2 and is usually cheaper.
Choosing the right service provider can be tricky, and often boils down to word of mouth, or 'gut instinct'. There are many service providers competing for your business so we recommend you use the search on that page reduce the list to a more manageable number of providers to consider.
Remember that if you're looking for a good personal service, the cheapest products and the largest ISPs are not usually the best choice. Try asking on our Message Boards in the "Which ISP" forum (residential / business) and comparing providers with our ISP Comparator.
This is probably because a previous resident of the property had ADSL or VDSL2 but did not cancel the service, or a broadband provider has not fully removed itself from the telephone line. The problem is often referred to as 'having a tag/marker on your line'.
This problem is very rare now, and in cases when it does occur it usually resolves itself once all the databases update to reflect the status of the telephone line. Worst case scenario is ordering a telephone service and once that is live you can subsequently order broadband as the update of the telephone records triggers an update to the broadband database.
Ideally if wanting to change service providers you should use the existing migration procedures. Where this is not possible you can cancel a service, and get your new provider to connect you again - this is referred to as a cease and provide.
Sometimes when ceasing (stopping) a broadband service a provider cancels your login but fails to tell the wholesale provider to remove the tag from the line that says you have ADSL already. It is possible for a broadband provider to issue all the correct paperwork, but for the wholesale provider to make a mistake too.
To get the Tag/Marker removed you should chase up with your new broadband provider, whose backroom support staff should be able to help.
Some places may call it an iPlate, but it stands for Interstitial Plate, which means the plate that fits in between.
The basic function of the Original I-Plate was to reduce the interference that the ring wire can introduce into the telephone wiring and slow down your ADSL and ADSL2+. The ring wire is the third wire in telephone extensions (connected to pin 3 at the BT master socket). For a telephone and ADSL to work only the wires connected to pins 2 and 5 are needed.
Openreach shortly after the original interstitial plate was introduced added a version with a built in socket for a DSL modem. In addition there are A and B IDC terminals so that a dedicated data extension can be wired up if desired.
Fitting an I-Plate is designed to be simple and does not require any changes to the telephone wiring in the home. Most people who can change a fuse will be able to fit an I-Plate. The sequence is laid out below:
Some broadband providers will order one for you upon request, or supply of part of their fault finding processes. There may be a charge for the I-Plate and/or delivery so check before asking for one.
A number of commercial outlets will sell you an I-Plate, which retails for around £10 to £20. If going to buy one, then for the small amount of extra hassle and cost you may find fitting an ADSL/VDSL2 faceplate to be neater, this reduces the impact of the ring wire, and also removes the need for micro filters on your telephones.
The I-Plate can improve some lines significantly, giving improvements of 4Mbps (4 Mega bits per second) for ADSL2+, the general rule is that the more telephone extensions you have and the closer to the exchange the larger the improvement is likely to be. The level of improvement from an I-Plate or faceplate filter is even higher on VDSL2 where some people have seen 15 to 20 Mbps gains if their connection was performing well what was expected.
You can determine what effect the I-Plate is likely to have by testing your broadband at the test socket that is revealed by removing the bottom half of your BT master socket, see picture below for where the test socket is located.
NOTE: The results from speedtest websites may not improve immediately if your broadband is still based on the old ADSL BT Wholesale solution but the vast majority of broadband now updates the through speeds within seconds of the speed improving. It is very important to also check the connection speed reported by your modem, since speed tests can be influenced by the performance of the provider at that time of day.
The I-Plate is actually a surprisingly simple device, we have dismantled one so you do not have to break your own.
In 2016 Openreach released the 5c version of its master socket. This new faceplate and master socket replaces the existing 5a and is installed in new homes or where Openreach visit to fix a fault and the master socket gets upgraded.
The important point to note is that the new design is not compatible with the majority of aftermarket faceplate filters, the only one we know that works is the Openreach faceplate filter that simply plugs in just like the I-Plate.
The tool-less nature means you don't need a Krone tool to push home wires, but rather the blue section lifts up and then clamps down onto the wires if you are fitting an extension. You will notice the extension wiring is part of the backplate, but when the bottom half of the master socket is removed the extensions are still disabled, meaning that the test socket is still good for testing whether your extension wiring is causing broadband problems.
The I-Plate while a nice and simple device, will cost many people money, and the simpler option of removing the ring wire from the master socket faceplate is a free option.
The image above shows a standard BT Master Socket with the removable faceplate lifted off. There are four wires connected; the blue pair to pins two and five, and the orange pair to pins three and four. The ring wire is the wire on pin three, i.e. orange wire with a white strip. It should be pointed out that old wiring may use just four solid colours and the wires will not be twisted together, in which case rewiring the telephone extensions in the property to use modern twisted pair phone cables is worthwhile; If you have two or more telephone extensions, you will find multiple wires connected to pin three.
To disconnect the ring wire(s) lift the wire away from the metal conductor as shown below:
Removing the wire on pin 3 on the other sockets around your property may help, but generally will have no effect. As with any changes make sure your telephones and ADSL still work and if not return your wiring to its previous state, to test the phones fully you need to make an incoming call to check they still ring.
NOTES:Where possible do not cut the ring wires, but lift them out of the connector, cutting them may leave you with too short a wire to reconnect when you move out of the property. If refitting a wire to connectors like those in the sockets, an IDC Krone tool must be used which can be purchased at stores that sell telephone extension kits (such as DIY stores) and also online.
This procedure of removing the ring wire is also useful if you do not have an identifiable master socket in the property.
The short answer is no. The longer answer is that if you do not have one of the suitable master sockets, you can call your telephone line rental provider and request the fitting of a BT master socket (known as an NTE5). This carries a charge which your provider should be able to advise you about.
If you have a telephone socket that looks like this:
Then these are normally used in properties which have two telephone numbers. You cannot fit an I-Plate, or any of the other ADSL faceplates to this type of socket.
The master socket which has the Openreach branding looks identical to older versions of the master socket. The difference is actually in the removeable faceplate.
The difference is small round lump in the bottom right corner of the device which holds the component to reduce the effect of the ring wire (which would connect on pin 3).
Older installations will have a master socket that was not designed to be accessed by the consumer, and thus does not have a removable faceplate. An example of this older style socket is shown below:
The options if you want to fit an ADSL faceplate or an I-Plate are to run a short wire from this socket to your own Master Socket that you have installed, or ask your telephone line rental provider what the cost would be for Openreach to attend and fit a new NTE5 master socket. This is known as a "Conversion of hard-wired master socket to Linebox and Regularisation of illicit master socket" in the BT Price List, or colloquially 'master socket normalisation', and costs around £25.
If the previous resident had broadband then do not panic, upon taking over a telephone line it can take the online checkers a few days to update.
Broadband providers should still be able to place an order if you explain the situation.
The online checkers take time to update, sometimes a week or more when the person whose name the telephone line is in has changed. This can result in slow speeds being estimated on the online checkers.
If you can find out from the previous resident what their actual broadband speed was, you should be able to achieve the same.
The online speed estimators where you put in your telephone number or postcode do nothing to actually limit your broadband speeds. If the checker is wrong your broadband modem will still negotiate the best speed possible for the parameters that have been set.
A short answer NO. A provider must allow you to migration even if you owe them money, of course ignoring any debt may serious implications in the future as providers may use a debt agency to recover monies owed.
If leaving a provider while within their minimum contract term you are liable for any charges as set out in the products terms and conditions and the notification letter when you initiate a migration should set these costs out. If the cost is too high you can cancel the migration.
If you have left a provider and dispute the charges they say you owe them, follow our resolving a problem guide.
The phrase 'camped on the line' is used to describe a situation, where you have moved into a property and took over the telephone line, but the old broadband is still active.
Your broadband provider should wait three days for the tag to clear and place a broadband order after this. If the tag fails to clear then given proof that you have taken over the telephone line they will arrange for the old broadband to be removed.
Prior to 2008 you would have to chase the old broadband provider yourself, or contac the TAGS helpline directly. In 2008 the systems have altered to make things simpler, and now it is the job of your new broadband provider to chase this situation up, and remove the old broadband service.
Switching the company who you pay your telephone line rental to will not affect the broadband, provided that the broadband and telephone are not a fully unbundled service (e.g. TalkTalk and Sky).
To move line rental provider, simply contact the new provider. One note of caution, if this new provide has telephone and broadband bundles make it clear that you DO NOT want their broadband. They should not be able to remove your broadband, unless it is a fully unbundled product, and even then they should have your permission.
Be aware that some providers who sell telephone and broadband as a bundle while they will technically allow you to move the broadband elsewhere may charge a supplement on the broadband fee if you move the telephone service away, supplements of £2.50 to £5 per month are not uncommon.
The price for a brand new line varies, from free to a worst case figure around £125, though very few people seem to pay the higher amount, around £60 is more common.
All the providers who sell telephone and broadband bundles should be able to order the install for a new telephone, though be aware that it can take several weeks for the install to take place, so if moving into a new property don't leave ordering the telephone and broadband to the last minute.
Switching providers is commonly known as a migration, and for the vast majority of broadband providers (namely those using ADSL, ADSL2+ or FTTC) it is very simple.
New rules that come into effect on 20th June 2015 mean that you should just need to order the service from your chosen new provider and they will contact your old provider.
Your old provider will send you a letter to confirm that you are happy to migrate and this gives you 10 days to reply and cancel the migration, i.e. to avoid a rogue sales person slamming your connection.
After 20th June 2015 anyone trying to issue or obtain a Migration Authorisation Code is out of luck. A new migration system has made the old MAC obsolete.
Our Migration Guide is worth a quick read and outlines the new process which is generally much simpler than the old system.
In February 2007 Ofcom announced General Condition 22, which provides rules for how migrations should take place.
Easy question, no needs a MAC to migrate after June 2015, the MAC system has been abolished.
The new migration system is controlled by the provider you are trying to switch to, and they or their wholesaler will inform your old provider, making migrations much simpler if you are leaving your old provider because you are not happy with the service.
Now that a unified migration system is in place no broadband service needs a MAC to migrate, just contact the new provider you want to join.
The broadband provider should avoid ceasing a broadband line at all costs, and suggesting this method rather than a migration is not the best practice.
A cease order will result in broadband being removed from your telephone line, and may lead to a delay of a week or more in getting broadband back again.
Ceases used to be free, but to encourage broadband providers to use migrations they are now charged £18.50 for every cease, and some providers pass this cost onto you.
The key thing to remember is that with a fully unbundled service both the broadband and telephone products are unbundled. This has previously often made switching provider difficult.
The changes in the broadband migration process mean so long as you are switching both phone and broadband to the same provider or you need to do is contact the new provider. If moving telephone and broadband to two different providers things are a little more complex as you need to get a Linked Order Reference Number added to the orders to ensure that the wholesalers are away that this is a linked order. Your chosen operator should help you with this.
The first thing to decide is whether you want to use your existing broadband provider at your new home. If you do not then what you should do is tell your old provider to cease your broadband by the date you are due to move out, and then order broadband from new at the new property. If you do the alternative of moving your old provider to the new home and them migrating you may find yourself stuck in a lengthy contract, and the probability of it going wrong are much greater.
The process for ordering broadband and a telephone line at a new home (this process applies even if the new home does not have an active telephone line) is outlined below:
Until a telephone number is actively in your name at an address it will not provide accurate estimated broadband speeds.
If possible obtain the telephone number of the line that is in use at the property currently, or ask them what speeds their broadband connects at.
