Connecting voice devices to a network infrastructure requires an in-depth understanding of the signaling and characteristics that are specific to each type of interface. Digital trunks are used to connect to the public switched telephone network (PSTN), to a PBX, or to the WAN, and are widely available worldwide. This course maps out analog and digital interfaces; examines analog voice ports, analog signaling, and configuration parameters for analog voice ports; and explains how to implement and verify digital trunks.
The course also explains the compression schemes that you can use to transport voice using various coder-decoders (codecs), and the implications of these compression schemes on bandwidth usage. How to calculate the amount of bandwidth that a VoIP call will consume is also explained. Finally, the course discusses the digital signal processors (DSPs) that convert analog and digital voice signals into VoIP traffic.
