What is 'network' in this context?

Ok, the only issue I have is the differentiation between a tandem and
network connection. They both seem to be paths, and the differentiating
factor is what happens to the data after it leaves the connection (does
it get forwarded on at the same layer, or does it get demux'd or adapted
up to a higher layer).
