I just remembered this site from my earlier telecoms work roles and it might be of interest for this module.
www.iec.org
This site, the American based International Engineering Consortium, makes available in their download area over 100 self teaching tutorials on a wide range of telecoms subjects. Each has its own self test after the main paper, and answers at the end.
The downside is - at least from here in the UK - is that the papers are largely but not exclusively drawn from the American viewpoint thus refer to ASNI standards e.g. their basic 56 k digital channels not European 64 k, and to SONET not SDH and so on in some fibre optic papers, although both SDH and SONET have their own main papers. On the other hand, there may even be overseas members working to north American standards. Some papers are also approaching 10 years old, so not always is the latest standard referred to.
I am aware that much railway telecoms are atypical of the general case, and many of the tutorials are of no use whatsoever in this environment. Nonetheless there are a few good papers - for example, the ''SDH'' document (attached if I can do it) describes more or less the fundamentals of an SDH (synchronous digital hierarchy) optical fibre network similar to the ''backbone'' of the Jubilee line (a network I have first hand knowledge of).
Also attached is the basic fibre optic technology file, as an example of what else is there.
To download the other PDF files go here:
http://www.iec.org/online/tutorials/
but you have to register, for free, all you need do is create a password.
Hope someone finds this useful , either for some revision or for some new learning.
