BT 21CN broadband service
BT have embarked on a large scale upgrade of the UK national telephone infrastructure. This includes new broadband equipment in exchanges and back-haul to ISPs. 21CN technology is being rolled out to the whole country over a period of many years.
Where 21CN technology is not available we can normally over 20CN broadband connections. We upgrade these to 21CN as available.
In some cases lines on 21CN enabled exchanges can have newer fibre to the cabinet services.

Upgrade
We upgrade lines from 20CN to 21CN as exchanges are upgraded as part of a bulk upgrade process. This can be some weeks or even months after the exchange upgrade. This is free of charge. We email customers in advance. There is usually an outage of a few minutes on the day of upgrade. The new tariff for 21CN applies from the next regular bill.
You can request an upgrade if your exchange has been upgraded, in advance of the bulk upgrade. This is chargeable at £12.92†.
Usage tariffs
All of our broadband services have a usage based tariff. You choose how many units per month in advance and can change from month to month if you wish. Using too little or too much is carried over to the next month within limits and using way too much means excess usage charges. The amount of usage you get for each unit depends on the time of day and what type of line you have. Only download counts, not upload. A unit is at least one gigabyte (GB) of peak download. Your usage does not have to be whole units at certain times, you can use some of a unit during the day and some in the evening, etc. Daytime usage is 9am to 6pm Monday to Friday and uses units the fastest.
