similar manner as IP or Internet Protocol relates to the Internet ("Public Switched Telephone Network," 2006). This is not a new innovation. It has a history. At the start of
the development of connections between telephones, the switches were analog, but today everything is done digitally ("Public Switched Telephone Network," 2006). This is a widespread phenomenon because as time goes
on, technology improves. Telephone numbers are important to PSTN. They are utilized to effect the switching ("Public Switched Telephone Network," 2006). One may compare this to the way in
which people go from one web site to another by typing in an Internet address. They are switched to a different page rather rapidly, as long as they are using
broadband. Interestingly, PSTN began with manual switchboards ("Public Switched Telephone Network," 2006). One will see this on old re-runs of Petticoat Junction and The Andy Griffith Show perhaps. The operator
would see a call come in and manually switch it from one locale to another. PSTN is a simple concept but draws on high technologically. Again, today, everything is done
digitally. Of course, while that is the case in a very general sense, in some older communities there are analog protocols in place ("Public Switched Telephone Network," 2006). The
purpose of PSTN is to route calls. It is a very simple function, but with millions of calls going through each day, one can see why efficiency is important. Clearly,
PSTN has made great strides over the years. 2. Describe what is meant by "postalized rates." Why are postalized rates available? Postalized rates is
