To allow communications between customers of different carriers, the carriers must implement physical connections between their networks. In this module, you’ll learn how the Internet is actually implemented, with peering and transit agreements at Internet Exchange buildings.
You will also learn about POPs in toll centers: how and where local exchange service providers: ILEC, mobile providers and CATV connect together and to other carriers for phone calls with a PSTN phone number; and SS7 to set up the calls.
We’ll finish by understanding where a CLEC fits into the picture with equipment collocated in wire centers.
