Test case for telecom cable network

How to make test case for telecom cable network so that it will help to get correct number signal from same cable.

hi suhir

you should have strong idea behind the signals before writing the test cases

analyse the classification of different cable structure

1.Fibre cable
2.undersea trunks
3.new copper technologies
4.new fibre technology

you should also have an idea about
copper twisted pair
cross talk
coaxial cable
dial up line

like this the topic goes on select the particular category in which you need to write test cases.. or else if you have prepared test cases please post it in the forum

Thanks
