A WAN connection many include specialized equipment to link the digital WAN link to your network router. In this video, you'll learn about the CSU/DSU and how it's used to provide WAN connectivity for your network.

My god this is a valuable video.
All the Cisco courses and books I have taken and read just use the letters "CSU/DSU" in a way that just assumes that we already know what you said in your video. What a massive gap this video has filled.
Twelve thumbs up.

I thought I was the only one! After taking Cisco CCNA Discovery 1-4 I was still confused about this! LoL

So is a CSU/DSU the same as a modem?

[@jasonkiel4686]

From some material that I had..."The CSU terminates the digital signal and provides error correction and line monitoring. The DSU converts the digital data into synchronous serial data for connection to a router...A modem converts digital signals to analog signals."
