This thesis is the culmination of a number of years work and there are many people I wish to thank for their contributions in either a practical or intellectual capacity: my supervisors, Dr Jeff Pressing, Dr Keith Winter and Jim Sosnin for their insights, advice and assistance; Graeme Gerrard for his assistance, generosity and friendship; Chris Vaughan, Harry Tagaris and Joe Kade for the ground breaking work on the second generation system.

I am also grateful to Kym Horsell, Chris Dick and Dr Manfred von Thun for the many discussions on programming and electronics over the years. Telecom Australia for giving me the time off to complete this thesis, in particular, the Exchange Interfaces project team for tolerating my occasional appearances.

Finally, special thanks to Marie for her friendship, support and encouragement throughout the project.
