Question

Wired telephones connect to an "end office" (also called a "central office") using what is called a "star topology", with each telephone connecting directly to the end office. In contrast, in a cable television network, each customer connects to the cable company's "head end" using what is called a "tree topology", in which a single wire (coax or fiber) runs down each street. As we will discuss later in the course, most cable companies provide packet-switched telephone service. However, if a cable company wanted to provide circuit-switched telephone service, we want to consider how it could do so.

a) How would it multiplex phone calls onto a single wire?

b) Where would the telephone switches be placed?

c) How much capacity (e.g., how many MHz) would be required on each wire?
