1 ­ Telecommunications & ICT
Learning Objectives
Describe the use of telecommunication and information technology in telephone systems
A long time ago, in a galaxy far far away. . .
Read the links here and here and think about all of the technology involved in communication in the
film star wars (or any other sci fi film).
List this technology and think about whether this technology would be possible today. What do we
have that is similar? Will this be possible in the future? Does it exist now?
Task One
Using the link on the right hand side and any other resources you can find make notes on the
following questions:
What is voice mail? How does it work? What facilities does it provide?
What would voice mail have looked like 20 years ago?
How does a telephone menu system work?
What does VoIP stand for? Describe how this might be used.
Voicemail is a new facility on landline and mobile telephones where someone can leave an audio
message for someone else when they are not present to answer the phone. The message is
stored within the telephone system and can be played back, deleted and saved whenever the
number for voicemail is called. This is normally 1571. The facilities of voicemail include the
storage of many messages and the deletion of messages either all in one go or individually.
Voicemail would only have been in the early stages of development 20 years ago and ICT has
advanced since them.
Most companies use an audio menu system for handling incoming calls. This involves a number
of levels where buttons on the keypad need to be pressed in order for the company to deal
with the enquiry. For example, press 1 for accounts, 2 for customer service and 3 to speak to
an operator.
VoIP stands for Voice Over Internet Protocol and is used in interactive systems. This is able to
convert spoken words into binary data (1s and 0s) and transfer them over the Internet.
