1. Broadband Connection Services

Broadband connection services represent a significant enhancement to the network connections previously available via dial-up services using traditional modems.

The term broadband covers a variety of technologies whose benefits include:

  • Faster connection speeds.
  • "Always-on" availability with no dialling required.
  • Simultaneous use of data and voice connections.
  • Simultaneous connection of multiple computers (may require additional equipment).
  • Fixed monthly subscription charges (although some subscriptions may limit the volume of data you can download per month).

The two main broadband systems currently in use for domestic users are:

  • ADSL (Asymmetric Digital Subscriber Line) which uses standard telephone lines in conjunction with an ADSL modem. The system is "asymmetric" because the data transfer rates are higher for information being downloaded than for that being uploaded.
  • Cable modem which connects a computer to a cable TV network and is therefore limited to those having such a connection available in their locality.
