Types of fibre-optic connection
The speed of your fibre broadband connection, which is measured in Mbps – (explained in the ‘Other terms’ section on this page) can vary considerably. The twotypes of fibre connection being installed by Connecting Shropshire are:
FTTC (fibre to the cabinet) – fibre-optic cables run all the way to the cabinet in the street, which can be up to 300m away. This is the most common connection.
FTTP: (fibre to the premises) – fibre-optic cables run all the way to the outside of your property. If you’re in an FTTP enabled area, you can benefit from download speeds of up to 300mbps (and upload speeds of up to 30mbps). However, not all service providers currently offer the service so you might not be informed by your Internet Service Provider (ISP) that it is available and may need to consider changing providers. Because FTTP is still a relatively new technology, there are a few differences in the customer journey when ordering fibre broadband, for more information, see: http://connectingshropshire.co.uk/fibre-to-the-premises-fttp-installation/
Asymmetric Digital Subscriber Line. ADSL is a technology that transforms a standard telephone line into a high-speed internet connection capable of simultaneously carrying voice and data. It is called ‘asymmetric’ because data moves in one direction faster than in the other. With the vast majority of broadband connections downloading data is usually faster than uploading data.
ADSL2 and ADSL2+ use the same cabling and exchange infrastructure as a regular ADSL connection. The software allows for greater amounts of data to be transmitted, which means that it can reach speeds of up to 3x regular ADSL – 24Mb download and 1Mb upload. As with ADSL connections, the distance of your house from the telephone exchange and the quality of the copper wiring can have a significant effect on the speeds you are able to get.
The capacity of your internet connection to transmit and receive data. Bandwidth is usually measured in bits-per-second.
A generic term for high speed digital internet connections. Broadband via a telephone line is currently available to 99% of households in the UK.
A combination of services from a supplier such as combined broadband and line rental.
This relates to the maximum number of users sharing the bandwidth available through the connection between your local telephone exchange and the Internet Service Provider. For example, a contention ratio of 10:1 means you will never have to share your broadband bandwidth with more than 9 other users.
Dynamic IP address
Your Internet Service Provider will have a range of dynamic IP addresses available and you are allocated one of these each time you connect to the internet.
A method of codifying information to prevent unauthorised access.
Gatekeeper software that guards against unauthorised access to your computer via the internet.
Internet Protocol address. A unique number used to identify your computer to the rest of the internet. An IP address refers to the host computer you are assigned by your internet service provider when you make an Internet connection.
Internet Service Provider. Typically this refers to the company supplying your Broadband service, e.g. BT, Sky, Talktalk, etc.
Megabits per second. A unit measurement that defines the speed at which information can be transferred through a network or cable.
A device that allows multiple devices to be connected together. Routers usually incorporate a modem to allow a shared broadband connection.
Broadband connectivity supplied from a satellite located in geostationary orbit.
The ability to connect to the internet without the need for any cables.
