CITM13 Digital Telephony. Tutorial 5 Further Asterisk
Now you have successfully used asterisk to create users (extensions) and places calls, it is
time to move on.
The next step in development is to create voice menus. Essentially these are m

CITM13 Digital Telephony. Tutorial 4 Asterisk GUI
Weve now covered protocols and CODECS. It is now time to get our hands dirty in the
world of VoIP. This week we are going to start with the Asterisk GUI. We will work in at
least groups of 3.
Satellite Link Design Considerations
Satellite links are widely used in telecommunications and television broadcast. The factors affecting a satellite
link are earth station characteristics, link BER, rain attenuation and antenna pointing errors.

Overview of Simulation
Simulation can be said to be a combination of art and science, in the sense that, the
expertise in computer programming account for the science part, while the skilled in
conceptual model formation
