INTRODUCTION TO DATACOMMS
This course has been designed to provide delegates with a basic introduction to data-communications. First the theory to voice analogue to digital conversion is provided, followed by the theory of the characteristic impedance, and Line Constants, Ohms Laws is introduced with a calculations performed by the participants.

The OSI Model is introduced, with the TCP/IP model, then various protocols are discussed using the model as a reference.

Prerequisites
None

Learning Objectives
At the end of this class, participants will be able to:

• Understand Analogue to Digital Conversion for the connection of voice to a modern digital network.
• Understand the need for multiplexing used to allow many voice connections on to a single Line
• Calculate the maximum power transfer for differing cable impedance and using Ohms Law.
• Appreciate the need for Synchronisation and where Asynchronous connections are used.
• Understand the operation of the Modem when connected to an ordinary Telephone line.
• Understand the various type of protocols used in the Network to carry data, eg X25, ATM and LAN Technologies.

Who Should Attend
Network technicians, Technical Managers and Support Staff who are new the Networks and need to understand the basis for all modern data-communication.
