Broadband

Various phone companies in the UK are rolling out 'cable modem' services. If you have Cable TV or phone services, a cable modem will give you high speed data access to the Internet. Cable modems run at downstream rates of between 500Kbp/sec and 100Mbit/sec, though that varies on your supplier and chosen service level. One major physical difference between ADSL and Cable is that with ADSL, your data is carried down your own copper pair (wire) all the way to the BT exchange. In the case of cable modems, you share a common 'bus' with your neighbours back to the head-end router in the cabinet at the end of your street.

Another difference between Cable and ADSL service is that the termination may be different - i.e. the interface to your own equipment. Cable service from Telewest and Virginmedia presents itself as an Ethernet (10BaseT) interface - suitable for connection to a network card in your PC, or an Ethernet router (e.g. Vigor 2900). ADSL on the other hand is available as either an ADSL modem with USB connection, or via an Ethernet router, depending on the service selected.

SDSL

Symmetric Digital Subscriber Line

SDSL broadband is a high speed internet service, offering downloads and uploads at the same speed. SDLS is ideal for businesses that need to be able to upload information quickly and efficiently. While it might sound complicated, an SDSL - or Symmetric Digital Subscriber Line - is basically the same as a standard internet connection but offers fast uploads as well as download speeds.

Why get SDSL broadband?

Normal copper-wire broadband, or ADSL, offers asymmetric broadband speeds - giving you a fast download speed but a much slower upload speed. A typical connection may offer download speeds of up to 8Mb or even 20Mb broadband but upload speeds at only 448kb - with a maximum of around 2.5Mb on high-end packages. SDSL is not subject to these limitations - your download and upload speed will be the same, giving you 2Mb uploads as well as downloads, for example. This makes SDSL ideal for home offices and business users that need to transfer a lot of data without being restricted by slow upload speeds.

Low Contention Ratios

Another common criticism of ADSL is the high contention ratios, with a standard package coming with a contention ratio of around 50:1. This means that you could be sharing your connection with as many as 49 other people on your road, which can really slow you down at peak times when lots of other people are also online. SDSL offers a much more attractive contention ratio ranging from 10:1 to 1:1, so you could have a dedicated line to yourself.

High Speed (Fibre)

FTTC (Fibre to the Cabinet)

FTTC is a method of delivering very high speed broadband to businesses and homes by shortening the distance the connection travels on the copper line. This is achieved by installing 'street DSLAMs' which act like a mini exchange close to the business or home. The connection between these Street DSLAMs and the telephone exchange is fibre (hence Fibre to the Cabinet). The remainder of the distance between the street DSLAM and the customer premises is copper, but the copper distance is short enough to use VDSL (Very-high-bitrate digital subscriber line) technology which has a maximum theoretical upload speed of 10Mbps and a download speed of 40Mbps.
