Here are 3 ways of receiving internet broadband access.

ISDN -          

ISDN stands for Integrated Services Digital Network. It is a type of digital data and internet service. ISDN is a digital service; your computer connects to the ISDN line and transmits without having to convert it into sound first.

There are two types of rate service

  • Basic
  • Primary

The terminal adaptor allows you to connect to two telephones each with there own number (as shown above). This provides three fully duplex channels. The first channel is used for control purposes and the other two are to carry out either voice or data. The rate at which data travels on these two channels is 64kilobits per second. The two channels can be used in parallel to provide a data transmission of 128Kilobites per second. The terminal adaptor connect to two telephones each with there own number. A router can be then connected directly to an ISDN line providing the internet service on a LAN network. When you connect to the Internet, the router will automatically dial the server provider to establish the connection.

There are different ways of using of using ISDN. While on one channel, you can talk and the second channel used for data transmittion or you can use both channel to obtain a high speed of 128Kilobite per second.

Uses for ISDN at Home!

With ISDN you can connect the home office from home. You can research via WWW and download various types of music. Use email to keep in touch, online gaming and holiday booking

Uses for ISDN at Work!

Online research via WWW as well as email to keep in touch with co-workers. Electronic diaries to keep information, remote working, faxing and video conferencing.

Advantages of ISDN

  • Less errors in the digital service
  • Connection will be fast
  • Higher bandwidth therefore faster downloading speeds
  • You can talk on the phone and surf the net at the same time
  • Video Conferencing
  • Not noisy compared to the analogue connection

Disadvantages of ISDN

  • The installation costs are expensive
  • If there is a problem in the system, there would have to be an engineer present to fix it.
  • It cost for you to convert the ISDN system back to an analogue system.
  • Some websites may have a different in speed of response
  • No difference to the browsing experience on the web

SATELLITE – Satellite internet doesn’t use a telephone lines or cable systems however it uses a satellite dish for two-way uploading and downloading data communication system. Satellite systems are 10 times faster then a modem system using one tenth of the 500kbps downloading speed.

Satellite internet consists of

  • A two foot by three foot dish
  • Two modems
  • Coaxial cables between dish and modem

It is important that there is a clear view to the south because orbiting satellites are over the equator. The internet uses an  technology which basically means up to 5000 channels of communication can be simultaneously served by a single satellite. This sends data from one point to many points by sending data at a compressed format which reduces the size of data and bandwidth.

Companies which provide this service include - StarBand, Pegasus Express, Teledesic ...
