In this module, we review the different types of telecom equipment, beginning with the essentials of the broadband telecom network: Ethernet switches and IP/MPLS routers, comparing costs and capabilities.
Then, we’ll review the different types of customer premise equipment for broadband.
To explain soft switches, call managers and SIP servers, we’ll begin with legacy CO switches and PBXs to see the fundamental differences.
Gateways and how they convert packets to channels completes the chapter.
