ISDN Question

Hi all,

I am studying using the Sybex N+ book. On the CD there are two bonus exams, one of the questions is as follows:



I can't for the life of me find the explanation of this in the book and I've tried looking on the web but again, nothing turning up. Can anyone shed any light on how this diagram works?
